2016 Albuquerque International Balloon Fiesta – Final Flight

I ended my last post by saying the final day of the 2016 Albuquerque International Balloon Fiesta may be a bust. It was raining when I went to bed Saturday night and looking at the forecast, I fully expected to hear raindrops on the roof when my 4:30am alarm sounded. I was surprised to find it wasn’t raining and dragged myself out of bed.

Brad picked me up at the Fiesta Park entrance. I had a nice chat with Johnny, the security guy there, while I was waiting. Hanging out with Johnny for 15-20 minutes every morning for nine days straight gave us a chance to get to know each other.

Breakfast burritos and excellent locally roasted coffee from Piñon coffee was served to pilots and crew at the pavilion. A great start to the day. They do a great job of feeding about 1700 pilots and crew on weekdays and up to 2200 on the weekends.

The pilot’s briefing had weather info that caught me by surprise. It seemed like a nice morning with favorable winds, however there was some ground fog to the east and the possibility of more fog in the river bottom as the dew point and temperature were close.

After sunrise, Brad gave the go-ahead to unload and assemble the Heart’s A’Fire hot air balloon. We had it cold inflated and I expected Brad to fire the burners at any moment when we were given the command to stand down. I didn’t know what was up but soon found out that the field had been closed due to the fog bank to the east. Ground fog can be very dangerous for flight as it makes it impossible to see and identify obstacles for landing.

We were soon back at it, inflating the balloon. I really like manning the throat of the balloon and watching it inflate. It can be taxing at times as wind or the weight of the sponsor banner makes the balloon want to roll on the ground. It’s important to keep the envelope properly oriented with the basket so the lines don’t twist and tangle. The lines connecting the basket to the envelope are numbered and we strive to keep number 10 and 11 centered on top as the basket lies on its side. I had some muscle soreness every day for the first week of the Fiesta but now I’ve worked myself into shape – just as we’re finishing up.

Brad’s passengers for the day were a special pair of siblings – brother and sister. They are the children of a good friend of Brad’s that’s an avid extreme hiker – more of a rock/mountain climber than hiker from what I understand. About three weeks ago, he disappeared while hiking 14,000 foot peaks in Colorado. Search and rescue operations searched for eight days before they were suspended. The kids haven’t been out of the house since his disappearance. Brad thought it would be good for them to get out, have a flight in the balloon and enjoy a day. He contacted their mother and invited them to go up.

We were given the thumbs up by the launch director and they were off!

Final launch of the 2016 Fiesta

We chased the balloon over to 2nd Street, west of the field. Brad had it working as he flew high and went north over the Sandia Pueblo Reservation, then dropped altitude and came back south down low. In fact he went low enough to dip the basket in the Rio Grande River – what they call a splash and dash! He did this a couple of times.

After more than an hour of flight time, he landed near the water diversion channel – about 150 yards from his landing the day before. This time he was on the west side of the channel and the access road had a locked gate. Lucky for us, a Sandia Tribal Police Officer had a key and unlocked the gate for us. Last year I heard horror stories of how the tribe treated balloonists and crews that landed on the reservation. This year there seems to be much more understanding and cooperation – I haven’t heard any bad stories, only good news.

After packing up the balloon, we had our usual tailgate party. Donna and our friend, Kris Downey, joined us. One of the crew members, Darren, thoughtfully lent us his Ford F150 truck so I could transport the Traeger grill, table, chairs and a few odds and ends from our site in the RV park to our trailer. Thanks, Darren! It would have been a real hassle to walk the stuff all the way to where we dropped the trailer.

I napped and watched football for the remainder of the day. At 4pm, Donna took a Lyft ride to an after-Fiesta party. She had a good time and was glad she opted for Lyft instead of riding the Spyder. We had another thunderstorm pass through. Besides, she could enjoy a couple of glasses of wine without worry. Brad and Jessica drove her back to the coach.

This morning I woke up a little before 6am. It felt luxurious to lie in bed for 15 minutes, then get up. I felt like I’d slept in. After a regular breakfast of eggs, bacon and toast with raspberry-ginger jam, I started packing up for the road. I had a few things I needed to take to the trailer. On my way walking back after the first trip, I saw Jim McManus with his head inside the battery compartment of a motorhome belonging to a solo woman RVer. I stopped to see what was going on. She had a problem with her house batteries not charging. The generator had tripped the breaker. When I checked it, the breaker didn’t feel right, the switch didn’t snap into place like it should. I worked it a few times and snapped it vigorously and it closed like it should. We checked it with a meter and it was charging.

On my next trip to the trailer, I saw Jim messing with a compartment door on the same coach. The door wouldn’t latch and they were trying to come up with a temporary solution. I checked the latch and it worked. The problem was that the squared-off U-bolt that it latches to wasn’t adjusted properly. The woman who owns the coach said she just had that compartment door replaced. It appears as though the shop didn’t lock down the adjustment nuts and they worked loose. Easy fix.

I like to help people out when I can, especially if I know what the answer to the problem is. Helping out here put me about 15 minutes behind schedule – but hey, what schedule? So I thought we could leave by 9am. What’s the big deal? I didn’t have to be anywhere at any special time. By the time I hooked up the trailer and loaded the Spyder, we pulled out at 9:30am.

We didn’t have any special destination in mind. I was thinking if we could make it to Holbrook, Arizona we could find a place to boondock for the night.

We’re not in New Mexico anymore

On the road, we thought about what we needed to do in the next three days. Tomorrow I want to stop in Mesa, Arizona at the RV Renovators to go over the work we need to have done to repair the damage caused by the suicidal deer in Idaho. Then I’d like to continue on to Casa Grande where I’ll have service work done at Speedco and a wash job at the Blue Beacon there. This had me thinking I should try to get closer to Mesa than Holbrook.

We ended up driving about 340 miles – a lot longer than we usually do – and are dry camped at a casino in Payson, Arizona. We started the day at an elevation of 5,000 feet above sea level in Albuquerque. Our route across I-40 took us to the Mogollon Rim in Northern Arizona – there’s some disagreement on how to pronounce Mogollon. This is probably due to various tribal dialects, Spanish speakers and settlers in the area. Most seem to agree it’s muggy-on. The Mogollon Rim brought us to an elevation of more than 7,700 feet. Now we’re right back where we started sitting at 5,000 feet above sea level.

Tomorrow night we can find another boondock spot – maybe the Elks Lodge in Casa Grande. Then we’ll move on to our little piece of desert in California west of Yuma/Winterhaven for the night.

It will be nice to have a quiet, secluded night before we move on to city life for the next three months in San Diego. I don’t think I’ll be posting for a couple of days as we take care of business.

Good to Have a Plan “B”

In my last post, I mentioned a problem with our awning. The pin that the upper eye on the gas strut mounts to came off. I temporarily installed it and secured it with wire. I needed a new clip washer to complete the repair.

Tuesday was our last full day in Santa Fe. While Donna went out for a run in the morning, I took the Spyder to Home Depot to see if I could find what I needed. No luck finding an actual clip washer. After searching around, I came up with something I thought might be workable. The pin is 3/8″ diameter. I found internal toothed lock washers and selected a package to fit a 5/16″ bolt. I figured I might be able to force the under-sized washer over the pin and the teeth would grip it.

5/16″ internal toothed lock washer

I tried to force the washer over the end of the pin by fitting a 3/8″ socket over the washer and tapping it with a hammer. The stainless steel washer was too stiff, I couldn’t get it over the pin. I used pliers to bend the teeth slightly, opening up the inside diameter of the washer. A few more taps with the socket and it was on. Then I used a punch tool and tapped the teeth firmly against the pin.

Washer locked down

This locked the washer in place. I’m fairly confident it will hold the pin. It took longer than it sounds, but in the end it was job done!

I downloaded another novel by Kyle Mills from Amazon to my Kindle Reader. This is my third book from this author – he writes a great story but the Kindle editing and formatting leaves a bit to be desired. There are typos and missing punctuation at times.

On Wednesday morning, I had much to do. I secured everything in the trailer and loaded the Spyder. I checked our tire pressures and put away the tire covers. I filled the fresh water tank and dumped and flushed the holding tanks. I worked for nearly two hours before I was ready to light the fires in the Cummins ISL diesel engine. We pulled out of Los Suenos de Santa Fe RV Park right at 11am. I usually prefer to hit the road earlier than that, but we were only going to Albuquerque – about 60 miles away.

Our first stop was at the San Felipe Truck Plaza in San Felipe, New Mexico – about halfway to Albuquerque. We’ve only covered a little over 200 miles since I last filled up in Raton, but we have run the generator a lot since then and I will be running the generator in the next few weeks. I like to have the tank topped up when I know we’ll be using the generator. Diesel fuel at the truck plaza was $2.19/gallon. That’s the least expensive fuel price we’ve had since we hit the road.

Our destination was Jessica Rice’s parents’ home in the North Albuquerque Acres neighborhood near Sandia Heights. Our plan was to dry camp on their property for a week until we move to the Balloon Fiesta Park. I had looked at the property on Google Earth and it looked large enough, but I thought I would have to back into their driveway or else I wouldn’t be able to turn around and maneuver.

When we arrived, we saw Jessica’s dad Bruce in the driveway. I stopped in the street and got out to look things over. The street was narrower than I expected. When I stepped out of the coach, I noticed that the edge of the road dropped off immediately into a ditch. I also found the weeds along the ditch were full of goathead stickers and my bare feet in flip-flops collected several. Ouch!

After looking the situation over, we decided we needed to go to plan “B.” The narrow road with no shoulder coupled with posts on each side of the driveway entry would make it difficult if not impossible to get into the driveway. Even if I made it into the driveway, there was less room than we thought there would be. I think Bruce was surprised at the size of our rig. Bruce felt bad about us having to go somewhere else, but it wasn’t his fault.

It’s always good to have a contingency plan when we’re going to an unknown dry camping place. We were invited to join Bruce and his wife Casey along with Brad and Jessica and Jessica’s brother Bruce and his wife Julie for dinner at the elder Bruce’s house around 5pm. Donna had baked pear gingerbread before we left Santa Fe in the morning to contribute to dinner. We left the gingerbread with Bruce and headed over to the Sandia Resort & Casino.

This was our fall-back option. We knew we could park overnight at the casino which is only about five miles from Bruce and Casey’s house. After some tight maneuvering in the casino lot, we found ourselves in nearly the same spot we occupied last year.

Donna took her laptop into the air-conditioned lounge in the casino and used her phone as a hot spot to get some work done. It was 87 degrees in the coach! Around 4pm, we rode the Spyder and made a stop for a quick cold one at Albuquerque Brewery which was near Bruce’s house. This is a small brewery making good beer to style. We met the brewmaster who is also one of the owners. We had a nice chat and enjoyed a pint before we headed to dinner.

Casey cooked up a large pot of southern New Mexico-style green chile enchiladas. These are different than the usual rolled enchiladas. It’s more like a green chile chicken stew served over a fried tortilla and it was absolutely delicious. The eight of us enjoyed the meal and conversation and had a great time. Casey gave Donna some of the leftovers and also a couple of servings of adobada (sometimes spelled adovada) which is a red chile marinated meat – most often pork or chicken but could also be beef. I’m not sure what’s in this dish, but I’ll find out for sure today. If it’s half as good as the green chile enchiladas were, it’ll be a treat!

We were having such a good time, I didn’t want to interrupt the flow by taking photos, so no pictures from the dinner party. It started to sprinkle as we were leaving but we managed to outrun the storm. Back at the coach, I covered the Spyder before the lightning, thunder and rain hit.

This morning it’s clear and sunny. We’ll move to an RV park on the west side of town called Enchanted Trails RV Park. I’ve booked a week there, then we’ll move to the Balloon Fiesta Park as planned.

*Just so you know, if you follow one of my links to Amazon and decide to make a purchase, you pay the same price as usual and I’ll earn a few pennies for the referral. It’ll go into the beer fund. Thanks!

Trouble with Fasteners

Sunday went pretty much as planned – I watched a lot of TV. First up was the Formula One race from Singapore, then it was NFL action for the rest of the day. Before I got through the race, we had a problem though. I was putting the awning out when I heard a sharp snap followed by a loud bang. I could see the rear support arm wasn’t extending like it should.

Upon inspection, I discovered that the pin the upper end of the gas strut is mounted to had come off. The pins used on the awning supports are held in place with thin clip washers with a serrated inner circumference. These are forced over the end of the pin and grip it, holding it in place. Well, the clip washer had broken off, allowing the pin to come out.

Upper gas strut mount broken

To get the strut back in place and insert the pin, I had to compress the strut. This is easier said than done, the pressure in the strut is amazingly high. With a little ingenuity, I was able to extend the awning support arm and lever the strut in place. Then it took several attempts using a large screwdriver as a pry bar to align the upper strut mount with the holes in the awning support and insert the pin. Once I got the pin in place, I temporarily wired it so it wouldn’t back out. One of the spacers is also missing, but the wire job kept the strut in place.

I need a bigger hammer

Temporary wire job

After I got the awning back in, Donna took advantage of the nice weather and walked to Sprouts to do some food shopping and also walked to Ulta. Then she rested her shoulder and read a book – one of my favorites – Zen and the Art of Motorcycle Maintenance.

On Monday morning, we were a little more ambitious and went to the Genoveva Chavez Community Center here in Santa Fe to play pickleball. We played for more than two hours and I think I got nine games in. I played much better than I did on Friday as I lost some of the rustiness from going months without playing. Donna’s shoulder issue is on her left shoulder. She’s right-handed so playing pickleball was okay for her.

I had another project in the afternoon. Our toilet seat cover is deteriorating. The toilet seat and cover are made from molded pressed wood particles and covered with a urethane finish. The urethane is flaking off in a few places and I can see raised areas where it’s separating from the pressed wood.

Old toilet seat cover

I ordered a new seat and cover from Amazon on Saturday. Tracking showed delivery to the RV park Monday afternoon – how do they do that? I walked up to the park office and asked about the delivery. I was told nothing came for me. I saw a flat box in the corner and walked over to look at it – sure enough, it had my name on it.

The new seat and cover are similar to the old one, but it has a soft-closing feature. When you lower the seat or lid, some kind of friction device lowers it slowly so it’ll never bang shut. Getting the old parts off and installing the new one was harder than it should have been. Obviously the seat and cover were put on the toilet before it was installed in the coach. I didn’t want to remove the entire toilet to change the seat so I had to be a contortionist to get to the mounting nuts behind the toilet. It took a little time and effort but I got it done.

New seat and cover installed

I have a gripe about the new cover though. Typically these are installed with nylon bolts through the mounting tabs and nylon nuts underneath the toilet to clamp the mounting tabs in place. Some whiz-bang engineer thought it would be wise to come up with a new way to accomplish this. The new nylon bolts have a circular shoulder with a groove around the circumference. The mounting tabs have plastic fingers that are forced into the groove when the mounting tab cover is snapped in place. These plastic fingers and groove are what holds the seat and cover to the toilet.

What were they thinking? Bolts, washers and nuts are clamping devices. The age-old method of using them as such to hold the seat works fine. With the new method I have problems. When the soft-closing feature has the cover slowly lowering, the leverage it has puts a large force on the mounting tabs. One of the tabs has popped out of the groove in the bolt several times already. Using the shoulder of the bolt to create a friction fit of the fingers in a groove is just plain stupid. I reinstalled the offending bolt this morning, we’ll see if it holds or if I have to come up with something else.

We’re expecting a high in the low 80s today. The weather guessers say there’s zero percent chance of rain. I’ll go to the hardware store and see if I can find a suitable clip washer for the awning – we’ll want to shade the coach with the awning today. Tomorrow we’ll leave Santa Fe and move to Albuquerque where we’ll be for the next 19 days.

Angel Fire Vietnam Memorial

It’s so quiet and peaceful here at Eagle Nest Lake, we decided to extend our stay two more nights. Donna hiked down to the Six Mile Creek day use area on Wednesday. Later we rode the Spyder to Angel Fire. We had pizza for lunch at the Angel Fired Pizza place and I needed to stop at a hardware store. Google maps showed Lowe’s right next to the pizza restaurant.

Lowe’s turned out to be a local grocery store – Lowe’s grocery. I found a lumberyard that’s also a True Value hardware and bought Gorilla glue for a project I needed to attend to. The support for the hanger pole in our closet broke. There’s a lot of weight on the pole from our clothes and some of the bumps on I-25 were pretty harsh.

Broken hanger pole support

I applied the glue and then screwed it back in place. I added cross screws for additional strength. I hope it holds up. Otherwise I’ll need to redesign the attachment. Our friend Dave Hobden had to rework his – he posted about it at UrbaneEscapeVehicle.

On Thursday morning, we woke to clear blue skies and the promise of a sunny, warmer day. I tried the panorama function on my Samsung Galaxy smart phone in an attempt to capture the beautiful view of the lake.

Here are a couple of signs by the visitor center giving a little information on the area. Click on the photos to enlarge if you wish to read them.

Donna said she thought she heard coyotes yapping in the distance before sunrise. I didn’t hear a thing. The nights are very dark and absolutely silent. I wouldn’t be surprised to find coyotes in the area. There’s an abundance of food sources for them – rabbits and prairie dogs are constantly on the move in the campground.

Ozark the cat amuses herself all day sitting in window sills or on the door step watching the prairie dogs.

Prairie dogs and their holes are everywhere

The park is home to a large prairie dog colony.

In the afternoon we rode the Spyder to Angel FIre. On the way we stopped at the Vietnam Veterans Memorial State Park. This was the first major Vietnam Memorial in the United States. It was started by Victor and Jeanne Westphall after their son, Marine First Lieutenant David Westphall was killed in an ambush along with 15 other soldiers in Vietnam on May 22, 1968.

In the ’60s, Victor and Jeanne purchased the 800-acre Val Verde Ranch and intended to open a resort. After David was killed, they built a chapel dedicated to his memory instead. This grew into a five-acre memorial site. Over the years, they sold off the ranch land to fund the memorial, which Victor mostly built himself. The chapel was completed in 1971.

Amphitheater behind the chapel

The memorial is now operated as a state park and is open year-round with no admission charge. It’s the only Vietnam Memorial State Park in the country. In 2014, New Mexico governor Susana Martinez announced the addition of 10 acres of adjoining land south of the chapel had been donated and is designated to become a rural veteran’s cemetery built to federal standards.

One of the most widely recognized aircraft of the Vietnam War era was the Bell Iroquois UH-1 helicopter – popularly known as the Huey. In 1999, the New Mexico National Guard brought a Huey to the memorial. This Huey served with the 121st AHC and is maintained by current and retired Guardsmen.

Bell UH-1 “Huey”

From the high ground of the memorial, I could see the runway at the Angel Fire airport. I was struck by the length of the runway – you don’t see runways this long at most small general aviation airports. Then it occurred to me – Angel Fire is 8,400 feet above sea level. On a hot summer day, the density altitude could easily exceed 10,000 feet. It takes a lot of airspeed to generate enough lift to take-off in this thin atmosphere. That means a long take-off run before the plane can rotate and also means touching down at high speed when landing. Thus the long runway.

That’s a long runway

We continued on to town and found the Enchanted Circle Brewing Company.

Angel Fire is a town of only about 1,200 full-time residents. But it’s a popular winter ski resort and has over 500 acres of ski slopes. Its mild summer climate brings mountain bikers and hikers, golfers and hunters come to the area in the fall. Hopefully this brings enough customers for the 20-barrel brewery with a 50-seat tasting room. The brewery opened in April of this year. The owners had the vision and built the place, then they advertised for a brewmaster! That’s right, they built it then they hired a brewmaster to create the beers.

We found their beers to be very good. I had a few small samplers then settled on the Glory Hole IPA. Donna had a plum sour then had a pint of stout.

Beers on tap

Donna had tempura battered veggies and I ordered hand cut fries with house made tartar sauce to go with the beer. It was worth the ride to town.

Today looks like another beautiful day with clear blue skies. Donna headed out at 7:30am and walked along the lake trail to the Eagle Nest village. She bought pastries at the bakery there and just returned with them, so I guess it’s time for breakfast.

Site 16 at Eagle Nest Lake

We’ll spend one more night here, then move on to Taos, New Mexico tomorrow.

Success at Last

In yesterday’s post I said I was giving up – throwing in the towel – in my attempt to remove the lower left front shock bolt. I made several phone calls looking for a mobile mechanic that could come to the coach with a large impact driver and air compressor. No luck. One guy returned my call and said he would do it if he was in the area, but he’s away on vacation until the end of the month. Another guy told me it would cost nearly $200 by the time I paid their standard minimum fees.

My daughter Alana said her neighbor does automotive work on the side and she was sure he had air-operated tools. The problem with that was getting the coach to his house to access his air compressor. Then I had an idea. I’ve had a large air compressor all along – the coach has an onboard air compressor driven by the Cummins ISL diesel engine. This compressor supplies air to reservoirs for the air suspension. It has a quick release connector for auxiliary air in the service bay at the right rear of the coach. All I needed was a hose long enough to reach from there to the left front and an air-operated impact driver.

Alana called her neighbor who invited us to come over to see what they might lend us. He wasn’t home but his wife showed us the tools. He had an Ingersoll-Rand 1/2″ impact gun and a 50-foot length of hose on his compressor. She told me I could take the hose and impact gun to see if it would work. The Ingersoll-Rand tool delivers more than 400 foot-pounds of force versus the cordless electric impact driver’s 330 foot-pounds.

The coupler on his hose didn’t match the quick connect on the coach, but I had a coupler and it was easy to change it. Fifty feet of hose was plenty to reach the front shock. I fired up the engine and ran it at high idle – 1,000 rpm. The compressor quickly built air pressure and I went to work. With the socket over the 28mm nut, I hit the trigger on the impact gun. BRRRRP. No movement. I hit it again. BRRRRP. No movement and it seemed like the impact gun was slowing down. Maybe the coach compressor didn’t flow enough air for full power. I waited for the pressure to build to the maximum and tried again. BRRR-ZING! The nut was free. Success at last!

The recalcitrant bolt

Ten minutes later I had the new shock mounted. Then I put the original coupler back on his hose and returned the tools. Job done.

I think Ozark the cat will be happy once she realizes I won’t be banging away with an impact driver under the coach anymore. It gets loud!

No more noise, Ozark

Later, the sun broke through the cloud cover. Alana prepared a vegan meal for our dinner. I’m a carnivore and I favor man-food like meat and bacon. But I was willing to give it a go. She made black bean burgers that were spicy and quite good. We also had french fried potatoes and sweet potatoes that I grilled and steamed green beans and artichokes.

Lainey, Alana, Gabi and Donna

With the daily rain showers and constant threat of rain, the Spyder has been relegated to the garage. The weather forecast calls for improvement over the rest of the week, but it’s still overcast this morning. Maybe we can get out on the Spyder to see some sights later this week.

Spyder stored in Alana’s garage

Alana is working today in the ER at Providence Hospital in Everett. She left us her car so we can visit our friend, Sini Schmitt, this afternoon. Other than that, I have no plans for the day and no unfinished chores.

Nuts and Bolts

Today’s post will be in two parts. First, I’ll catch up on social activities and then share my technical woes. On Friday afternoon, Donna marinated boneless chicken thighs with olive oil, garlic and fresh herbs. I grilled them on the Weber Q for dinner. My daughter Alana eats a modified vegan diet to control lupus and our granddaughter Gabi is vegan. Donna made teriyaki tofu bites for Alana and I grilled a hot vog (vegan hot dog) for Gabi.

We sat outside at our table and enjoyed the sunshine while we had a chance. Other than Wednesday, we’ve had periods of rain showers every day since we came to Arlington.

Dinner in the open air and sunshine – clockwise from left – Donna, Alana, Lainey and Gabi

Saturday evening we were all invited to go to Alana’s mother’s house and have dinner with LuAnn and her husband Jerry. We had a break in the weather and enjoyed hors d’oeuvres outside in the backyard. LuAnn set a table of appetizers including spicy shrimp on marinated cucumber slices.

Appetizers

We moved indoors for dinner which featured grilled salmon, roasted potatoes, corn on the cob and asparagus.

Dinner table – clockwise from left – Donna, LuAnn, Lainey, Alana, Gabi and Jerry

We all had a good time. After dinner, Jerry and I sampled a couple of fine Scotch whiskys. First up was a glass of Ardbeg Islay scotch – very smokey and complex. Then an 18-year-old Glenmorangie Highland scotch. Good stuff indeed!

The rest of my weekend was spent trying to complete my shock absorber installation. Before I get into that, I want to talk about properties of materials – specifically, rigidity and deformation. Any mechanical engineer will tell you that there’s no such thing as a totally rigid material. Everything flexes or deforms to one degree or another.

An extreme example happens everyday. Have you ever been stopped in traffic on an overpass? Did you notice how you could feel vibrations and even sense movement when a large truck passed by on the opposing lane as you sat stopped in your car? That’s the concrete and steel structure of the overpass slightly deforming and flexing temporarily from the moving weight of the truck.

Materials have limits of flexibility and deformation. Elastic deformation occurs when the force is large enough to deform the material (yield), but it allows the material to return to its original dimensions. Plastic deformation occurs when the force applied is large enough to exceed the elastic limit and the material is permanently deformed – it doesn’t spring back to its original shape.

When we apply these concepts to fasteners – such as nuts and bolts – we want to tighten the fastener enough for it to yield within the elastic deformation range. This causes the threads of the bolt and nut to fully engage and maintain their tightness. When we remove the nut from the bolt, the threads spring back to their original shape and can be reused.

I’m telling you this to explain why I spent the rest of my weekend struggling with a nut and bolt. The lower bolt on the driver’s side shock is locked solid. I worked all day Saturday and again on Sunday with the cordless electric impact wrench and haven’t been able to budge the nut. I also used a 24-inch breaker bar and pulled myself up on it from underneath and bounced my body weight until my arms gave out. I believe the mechanic that installed the shocks over-torqued this nut and deformed the threads permanently – plastic deformation – and they refuse to unlock. I finally threw in the towel last night and gave up.

Today I’m looking for a mobile mechanic that can come over with a 1-inch impact driver and pound the nut off. Once off, I’ll inspect the fastener carefully for permanent distortion or cracks before I install the new shock. If I find any damage, I’ll have to replace the fastener.

Just Four Bolts

I mentioned taking delivery of a pair of new front shock absorbers for our coach. The current set of shocks was installed just two years ago, but the trip up I-5 made it obvious that the front shocks weren’t holding up. A vehicle weighing more than 30,000 pounds has to have high spring rates and serious dampers to control the suspension.

Shock absorbers exist to damp the action of the springs. Undamped, the springs would compress over a bump, storing energy in the spring. The spring would then extend, releasing this energy as it elongates past its resting length, only to return to a compressed state. This cycle would repeat until the energy is dissipated through friction and heat. The vehicle would bob up and down like a boat going over swells in the ocean.

Getting the damping rate right isn’t a simple matter. Hydraulic shock absorbers have a piston inside a cylinder filled with fluid. The piston is connected to a shaft that extends from the cylinder. Typical installation has a fastener at the closed end of the cylinder opposite where the shaft exits and another fastener on the end of the shaft. Suspension movement strokes the piston in the cylinder, moving it through the fluid.

Slow movement of the shaft, such as compression of the front suspension when braking, or cornering, requires a high damping rate to limit the movement of the suspension. You don’t want the front suspension to compress or dive excessively while braking or roll from side to side when cornering. This is accomplished by forcing the fluid through a small port in the piston. The size of this orifice sets the low piston speed resistance – the damping rate.

Conversely, when the piston moves at high velocity – such as when hitting a square edge bump like an expansion joint where the road meets a bridge or a pot hole – we want the spring to compress and take the hit without transmitting it to the chassis. The orifice used for low-speed damping is insufficient to move the fluid quickly enough through the piston and the shock would hydraulically lock. What the shock designers typically do is add a number of high-speed ports – a ring of orifices through the piston.

This ring of orifices allows much more fluid movement – but how to keep fluid from moving through these holes when we want stiff low-speed damping? The most common way is to cover these high-speed ports with a thin metal shim. A stack of shims can be made to gain the proper stiffness of the cover over the hole. When the piston moves through the fluid at a high enough speed, the shim flexes as the fluid is forced against it – as it flexes away from the holes, it uncovers them and the fluid can pass.

Our current front shocks are Koni FSD series 8805. These shocks are designed pretty much as I described above. The piston in these shocks have a 36mm diameter. Hitting sharp irregularities in the road wasn’t an issue when these shocks were new. Over time, they gradually lost the ability to transition from high-speed damping to low-speed damping after hitting a sharp bump. It’s like the high-speed ports stay open too long, allowing the coach to bounce on the springs three or four times after hitting the bump.

About five months after I bought these shocks, Koni came out with a new replacement for use on the Alpine Coach Peak Chassis and Monaco Roadmaster RR4 chassis. This new shock, designated the Evo 99 series, has a 50mm piston and revised valving. The 40% larger piston allows the shock to operate at much lower fluid pressures and should enhance durability.

My task on Thursday was to remove the old front shocks and install the new series 99 shocks. It’s only four bolts – one on each end of the two shocks. How hard could that be, right? Well, I remembered when I had the shocks installed, the guys used cordless electric impact wrenches to remove and install the shock bolts. The mounting bolts were stubborn and it took two mechanics about an hour to replace four shocks.

The first thing I had to do was buy a 28mm socket and a large breaker bar to break the bolts loose. I bought a 24″ breaker bar and I couldn’t get the bolt to budge. I needed an impact driver. I borrowed my daughter Alana’s car and drove to Harbor Freight in Everett. I used to have a few impact wrenches in different power levels, but they’re long gone thanks to those Dirty, Rotten Thieves. I figured I could buy an air operated impact driver at Harbor Freight for about $40.

When I got there, it occurred to me that I only have a small, portable air compressor with only a few gallons capacity. In my sticks-and-bricks garage, I had a 60-gallon compressor that powered air tools easily. Although my little compressor can reach 150 psi, it doesn’t have a fast enough flow rate to power a big impact driver. I needed an electrically operated impact driver. I found a cordless impact driver with a 330 ft-lbs torque rating. It was branded Chicago Electric – Harbor Freight’s Chinese sourced house brand. I paid over $100 for it.

By the time I got home with it, it was after 1pm. I needed to charge the 18-volt battery before I could use it. It has an 18-volt nickel-cadmium (NiCad) battery. NiCad is old technology, but it works. The first charge on a NiCad is important as it forms the cell. I charged it for 90 minutes – the day was getting away from me. It takes three or four full charges before a NiCad reaches it its full capacity. After charging the battery, I had to allow another 15 minutes for it to cool before using it.

I started banging away on the first bolt with the cordless impact driver. I would hit it for several seconds, then stop to keep from overheating the motor and battery pack. After about 10 minutes of this, I needed to charge the battery pack again. Arrgh! This entails a cooling period for the battery before charging, about an hour or so of charge time, then another cooling period before attacking the bolt again. I had the first bolt off by 5pm and called it a day!

Friday morning I was back at it with a fully charged battery and started on the second bolt. After two charge cycles, I had it off. Removing the shock and installing the new one was fairly easy – it only took about 10 minutes. Getting the new shock in place entailed holding it at arm’s length with one hand while I was bent over the front tire with my head in the wheel well, then inserting the mounting bolt with my other hand. It was a workout!

Now I had to start the charging – working – charging – working cycle on the other side. By the end of the day, I had one bolt removed from the other shock before I gave up. It was beer-thirty and I was ready for a cold one.

Today I’ll start over and remove the last bolt. A lot of work for four bolts!

On Thursday evening, we received tragic news. Our friend Sini Schmitt texted Donna to inform her of the passing of her husband, Bob. Bob died unexpectedly while they were vacationing in the British Virgin Islands. We met Bob and Sini in San Diego a few months after we first hit the road. Since then, we’ve met up with them in Arizona and again in California and always had fun times together. I’m deeply saddened by Bob’s untimely passing. He was a great guy and will be missed by many.

Oregon IPA Quest

Monday was a fairly quiet day for me. Donna wrote the blog post, so I had the day off from that. When I say quiet, I mean as far as activity goes. We seem to find places that are on flight paths wherever we go. Here at Columbia River RV Park we’re on the west side of the Portland International Airport (PDA).

PDA is a joint military-civilian airport and it’s the largest in Oregon. It seems like activity ramps up around 6am. Take-offs from runway 28L pass just to the north of the RV park over the Columbia River. Flights from the busier runway 28R pass well north of here. The commercial flights are reasonably quiet – we sleep through most of the early morning traffic. Some days, military aircraft fly by – F-15 Eagles of the Oregon Air Guard. These are supersonic tactical fighters capable of reaching speeds of mach 2.8 (2.8 times the speed of sound). As such, they have very powerful engines – two Pratt and Whitney F100 axial compressor turbofans with afterburners.

Of course they aren’t exceeding the speed of sound when they fly by here, but the engines roar and you can hear the air parting and rushing back into the void as they speed by. Last week they passed overhead in pairs. This week they’re going by four at a time. It only happens a couple of times per day so I’m not complaining. Ozark the cat stops whatever she’s doing and looks up at the ceiling in the coach whenever they fly by.

On Monday evening, I continued my quest for the great Oregon IPA. This time I sampled a beer from Old Town Brewing called Shanghai’D. It’s a medium bodied IPA and not overly hoppy – more in the English style and very drinkable at 6.5% ABV. Old Town Brewing is a brewery and pizza joint with two locations in Portland. One of their claims to fame is the fact they deliver beer! That’s right, you can call in a beer order within a certain range of their location and they deliver by bicycle.

I picked up this bottle at Walmart. In Portland, Walmart has a sizable selection of craft beers. When I rode the Spyder over to Walmart on Monday afternoon, the traffic on eastbound Marine Drive was backed up in front of the park. I had to wait for a car to clear the intersection as the traffic crept along before I could hit the westbound lane.

I came home through residential back streets as I could see the traffic jam hadn’t unsnarled yet. Later I found out the cause of the traffic. Monday was the start of the Cambia Portland Classic – A Ladies Professional Golf Association (LPGA) tournament that runs all week through July 3rd. The classic is held at the Columbia Edgewater Golf Club – just east of the RV park on Marine Drive.

On Sunday’s bicycle ride, Donna had trouble with the left pedal on her bike. She uses SPD type pedals that she clicks into with cleats on her cycling shoes. She likes the SPD type because they allow her to use shoes that are comfortable to walk in. I took a look at her pedal Tuesday morning and saw the problem. A part on the pedal that applies spring pressure to the mechanism had broken off. I took the pedal to a bike shop nearby to see if I could get the part for it. The guy there told me he didn’t have the part, but he thought I may be able to find it at another shop a few blocks away where they hang on to old stuff to take parts from. Then he added that in his experience, the cleat is usually wallowed out when this happens and won’t hold up. I bought a new set of pedals.

After I installed the pedals, Donna and I went for a ride. We followed the trail east on Marine Drive to the I-205 crossing, then turned back. We had a tailwind getting there, which meant a headwind on the way back. For some reason, I developed soreness in my right knee on the ride. I was riding my mountain bike and the upright position makes riding into the wind a real chore. I didn’t ride my road bike because my shoulders and neck got stiff on my last road bike ride.

When we reached the M James Gleason Memorial Boat Ramp and Park, I peeled off the bike path as Donna wanted to ride up 33rd Avenue to get in some more miles and then do some grocery shopping at New Season’s market. I took a look at the beach area on the Columbia River before heading home. For a Tuesday afternoon, it was busy.

The temperature was in the 80s – nice beach weather.

Later, we decided to grill the lamb chops Donna bought from the rancher down the street from the RV park. Donna marinated the chops with olive oil, fresh rosemary and oregano, lots of garlic and lemon zest. I grilled them on the Weber Q. They were great!

Donna served them with steamed green beans and Moroccan quinoa. Delicious!

I paired it with another IPA I found at Walmart. This one was from Laurelwood Brewing in Portland called Workhorse India Pale Ale. This is a big beer at 7.5% ABV, double dry-hopped and full of citrusy hoppiness.

This morning we have overcast skies – I couldn’t see the F-15 Eagles fly by but I sure heard them. The cloud cover should burn off by noon and the forecast calls for a sunny 83 degrees this afternoon.

I tackled a minor repair on Tuesday. Most states require trailers with a gross weight of 3,000 pounds or more to have trailer brakes that automatically engage if the trailer accidentally separates from the tow vehicle. Our trailer is equipped with a breakaway switch that activates the brakes if a pin is pulled from the switching device. A length of cable connects the pin to the tow vehicle. If the trailer comes loose, the cable pulls the pin and the brakes are applied.

Breakaway pin and cable ends

The cable has a loop for the pin and a loop on the other end that I connect to the receiver hitch with a carabiner. I’m not sure how it happened, but the cable must have dragged on the ground at some point and wore through, separating it into two pieces.

Steel cable separated in the middle

When I went to Walmart the other day, I saw a fisherman’s supply store. I stopped in and bought some nylon covered stainless steel leader cable and some double barrel crimp connectors.

This made it easy to create a new breakaway cable for the trailer.

That was easy – job done!

In the afternoon, Donna and I rode the Spyder down NE 33rd Drive and found the store Ray told us about. It’s called New Season’s. It’s similar to Sprouts – a store chain we like in the southwest. It’s an upscale store, so you have to shop carefully as the prices can be good or they can be high. Donna had defrosted the refrigerator in the morning and now it was time to restock it.

On Wednesday morning, we rode the Spyder to Beaverton to visit with our friends, DeWayne and Marlo. They live in a co-op housing development which is basically condominiums with shared community areas. Residents sign on to teams to develop and maintain community property. They have shared garden space, community meeting rooms, a woodworking shop and more. DeWayne runs the wood shop and also leads the building repair and maintenance team.

After giving us a tour, DeWayne had a project to work on and I left Donna and Marlo to their girl talk. I rode the Spyder over to the Hillsboro airport where I wanted to check out an aviation museum. When I got there, I was disappointed to see a closed sign in the window. I looked at the hours on the door – it said 9am to 4pm Monday through Thursday. A woman inside saw me looking and came to the door. She pointed at a guy out front spraying weeds.

The guy came over and introduced himself and told me they were in the process of moving the museum to Tillamook. All but one of the flyable airplanes had already been moved. He offered to give me a tour of the remaining aircraft and parts, but warned that things were in a bit of disarray.

I took him up on the offer and we spent about an hour looking at old planes and parts. They have mostly military jet aircraft from the 1950s to the 1980s. The owner has a number of contacts in foreign governments and wheels and deals for airplanes. A number of their aircraft came from Taiwan. They also had Soviet airplanes from Poland and Czechoslovakia.

I rode back and picked up Donna a little past noon. It was a short visit for the girls, but they were happy to catch up in person.

Marlo and Donna

Instead of riding the freeways home, I took us down Burnside Street into downtown Portland. We stopped on Alder Street where all the street food vendors are located. There are dozens of food trucks and small stalls lined up over two blocks. We arrived a little after 1pm and missed most of the lunch crowd. After walking down the street and looking over the offerings, we both went for Thai food. It was a tasty lunch on the street.

After we came home, I retrieved a couple of packages we received at the office. One was a chair that Donna ordered from Bed, Bath and Beyond, but it wasn’t what she expected so it’s going back. Another package was our mail from our service in South Dakota. This package included new license plates for our coach and Spyder. The design on our current South Dakota plates was first issued in 2006. After 10 years, some of the plates are deteriorated and hard to read or have lost their reflective properties, so South Dakota decided it was time to issue new ones.

I took a photo of our new plates and made a discovery. When light is directed at the plate (in this case via the camera flash), a squiggly line appears in the middle from top to bottom. I suppose this is an anti-counterfeit feature.

Donna went for a bike ride as she continues to aim for her 250-mile Great Cycle Challenge goal while I installed the plates. After I put the plates on, I had a message telling me another package arrived at the office. It was the Elka suspension I ordered for the Spyder – custom made shock absorbers and springs. I paid for expedited shipping since they came from Canada. I didn’t want them to get delayed in customs and have them arrive here after we’ve moved on. Timing of package deliveries can be a challenge on the road.

Last night Donna made baked shrimp with fennel and feta for dinner.

I paired it with an Imperial IPA from Hop Valley Brewing in Eugene, Oregon. It was delicious – the shrimp I mean.

We ended an excellent day by starting season two of True Detectives. It appears that season two has no connection with season one – we’re starting a whole new story line with different actors.

After a few days of great weather, rain moved in last night. We have a heavily overcast sky this morning and expect rain off and on all day with a high temperature only reaching the low 60s. I’m chomping at the bit to install the new suspension on the Spyder, but it looks like that will have to wait.

Road Bike Ride

Donna had another article assignment to complete on Monday. While she was doing that, I made a run to Walmart to pick up a few groceries. While I was out, I also picked up supplies for two upcoming projects. When I came home, I found a Yamaha FJR motorcycle at our site. Our friend Ray, who we met in San Diego through Kris and Tom Downey, stopped by. He and his wife Kathy live nearby and knew we were here via this blog. We hope to get together with them this weekend.

I went to work on another project before lunch. The rear end of the floor in our trailer has a metal trim. The original trim was stamped aluminum sheet – very thin and mostly decorative. A while back when I was loading the Spyder, I had a little wheel spin as I was backing in. The tire gripped the trim and tore it away from the floor.

Trim damage due to wheel spin

I cut the damaged portion away and overlaid a 36-inch section of extruded aluminum trim that’s 1/16 inch thick. This is much heavier than the original stamped sheet aluminum and should stand up to abuse.

With that job done, we had lunch and headed out on our bicycles at 2pm. I don’t remember when I last went out on my Orbea road bike. We headed east on Marine Drive and picked up the paved bike path. It’s been a while since Donna and I rode bicycles together – my mountain bike can’t keep up with her road bike. We first met in a cycling club in Mesa, Arizona where we rode together almost every weekend.

My Orbea is a full carbon fiber road racing machine. As such, it handles much quicker than my mountain bike. It felt lively and a little skittish at first. When I ride my mountain bike, I wear hiking shoes and the pedals have small studs that help me grip the pedals. On my Orbea, I have Speedplay pedals that I clip into with special cleats on my stiff Sidi bicycling shoes. To unclip from the pedal you have to twist the rear of your foot away from the bike and it will release. At one point on the trail we stopped to admire the view. I forgot to twist my foot and my right shoe was caught on the pedal. I fell slowly into the weeds on my right shoulder. It probably looked comical, but it wasn’t fun.

After that, I quickly became reacquainted with my road bike and settled into a rhythm. East of the I-205 bridge we stopped to look at Mt. Hood and take a selfie. I’m not too good at shooting selfie type pictures.

Not too good at selfies

We rode about 10 miles east, then turned around. This stretch of the Columbia River has a number of uninhabited islands. We saw people on the island beaches that they reached by boat. We also saw an old shipwreck – a sailboat that must have broken loose in a storm and ended up beached on an island.

On the ride back, we saw an osprey struggling to gain altitude with a large fish in its talons. The osprey was a large bird – its wingspan had to be nearly six feet. The fish was weighing it down but it slowly circled upward and away from us.

We wanted to grill steaks on the Weber Q for dinner, but I realized I was out of propane. I made another run to Walmart and picked up four propane canisters. While I was there, I also found another local IPA to try. It was from Pelican Brewery in Pacific City, Oregon. It’s an IPA that’s brewed with a single hop variety – Ella hops from Australia. They use this hop type in the boil and then dry hop twice with them.

Umbrella IPA

This was solid example of west coast IPA. It went well with the bacon-wrapped filet mignon. While I was grilling the steak, Donna prepared sauteed mushrooms and onions and sides of rosemary and garlic roasted fingerling potatoes and steamed broccoli.

It’s been awhile since we had steak and Donna said she was craving it. All in all, it was meal fit for a king (and queen). After dinner we took a walk through the RV park and then settled in to watch another episode of True Detective. This series starring Woody Harrelson and Matthew McConaghy really keeps you guessing as to where it’s heading.

Ozark the cat wanted to recline in front of the refrigerator but apparently the floor isn’t comfortable there. She pulled out the little rug in front of our shower and made herself a bed.

Ozark making it comfortable

The weather forecast calls for another nice day with a few clouds and highs in the upper 70s. I have one small project to complete on the trailer. Donna is defrosting the refrigerator – something we haven’t had to do in nearly eight months. After the refrigerator is defrosted, we need to stock up on groceries. We want to check out a few stores that Ray told us about.
