2015/11/17 (T) Drivable Again

Linda set her iPad alarm for 5:45 AM.  I heard it go off and got up shortly thereafter even though I did not turn out my light last night until 12:30 AM.  She got up at 6 AM and was showered, dressed, and out the door by 6:20.

I tuned in Weather Nation on WILX TV out of Lansing while I folded the clean laundry.  Of all the stations we can pick up this is the only one with a dedicated weather sub-channel.  The current forecast was for two more days with high temperatures near 60 degrees F but high humidity and rain as moisture races north from the Gulf in advance of a cold front.  By the weekend we are looking at highs at or barely above freezing and lows in the low 20’s.  The 10-day forecast has us back in the 40’s by Tuesday so we should not have any weather difficulties for Thanksgiving and the following day when we head south.

We planned to re-install the two front seats in the bus late this afternoon and I plan to take it on a fueling run tomorrow so I can run the Aqua-Hot diesel-fired hydronic heating system instead of running electric heaters.  I will also drain and refill the fresh water tank, but those are tomorrow’s tasks.  I had other things to do today, starting with the laundry.

I needed to wait until late morning to do the final cleaning of the tile in the cockpit and had several things to do that had to wait for the cleaning to be done first.  To make good use of my time I decided to measure, cut, drill, and paint the 1/2″x3/4″ aluminum angle that will serve as a retaining bracket for the refrigerator.  I will install it tomorrow after the front seats are re-installed and out of the way.

With that done I got the 3/4″ piece of walnut that Jarel cut and shaped for me to cover the front edges of the plywood under the refrigerator.  The piece sticks up a little above the top of the top layer of plywood so I wanted to install it in a way that will allow it to be easily removed.  That precluded the use of nails, even small ones.  I did not want the appearance of screw heads and wasn’t interested in drilling deep countersunk holes and using plugs.  (The woodwork in the bus was essentially assembled this way and most of the plugs have come out.  We will probably put them all back in once we are done reconditioning the wood even though I would rather not.)  That left Velcro as the only reasonable option, so I started a shopping list.

My next mini-project was to attach the 1/4″ walnut veneer plywood to the face of the pull-out pantry.  Jarel had ripped two pieces to the proper width for me but neither one was quite long enough to fully cover the front of the pull-out pantry.  Step 1 was figuring out where to have the two pieces meet and then determine how long each piece needed to be.  The next problem to solve was how to attach them.  I decided to use glue, clamp the walnut panels to the front of the pantry, and then secure them using screws from behind.  I looked for my large wood clamps but could not find them so I added face clamps to my shopping list.

The front structure of the pantry is 1/2″ thick ash and I planned to drill countersunk holes from the inside so the screw heads would be flush.  That meant I needed #6 5/8″ screws, which I did not have, as 3/4″ screws would probably puncture the veneer.  I added the screws to my shopping list.  I selected a small drill bit and drilled holes from the inside just below the top board and just below each shelf plus one just above the bottom shelf.  Because of the metal side plates these locations were easier to reach on the inside.  I then switched to my countersink bit and drilled the holes out from the inside.

Back in the garage I sprayed a second coat of black paint on the aluminum angles for the refrigerator retaining bracket, moved a load of laundry to the dryer and put another load in the washer, and then took my shopping list and went to Lowe’s.  Lowe’s had a very clever Automax self-adjusting face clamp with a 6″ reach.  It was a little pricier than the 3″ version which was a little pricier than the 3″ manual adjust version, but the size and auto adjustment feature swayed my decision.

On the drive back to house I had a nice QSO with Steve (N8AR) on the South Lyon 2m repeater.  When I got home I had some wasabi/soy almonds and sourdough pretzel nibblers with hummus for lunch.

Returning to the bus work I cleaned the tile in the cockpit using Armstrong Once ‘n Done and rinsed it with a clean sponge and warm water.  I then returned to working on attaching the walnut veneered plywood to the face of the pantry.  I decided which piece to use for the longer bottom section and which portion of the other piece to use for the top section.  In the shop I clamped each piece in turn to a 2×4, set the Boca saw guide, and trimmed them to length.

The 1/4" walnut veneered plywood clamped to the front of the pull-out pantry.

The 1/4″ walnut veneered plywood clamped to the front of the pull-out pantry.

Back in the bus I applied the bottom piece first.  It was slightly curled, lengthwise, so after applying Titebond II glue to the back I positioned it using the two Automax face clamps and then used C-clamps with scrap pieces of underlayment to hold it flat while protecting the veneer.  I then installed #6 5/8″ SR screws from the back to secure the face plywood.  I installed the upper panel using the same procedure.

We are using the same handle for the pantry that we have used throughout the bus.  Jarel made a 4-1/2″ by 8″ piece of 3/4″ walnut with coved edges to serve as a decorative base for the handle and to cover the joint between the upper and lower pieces of veneered plywood.  I marked the vertical centerline on the back and then marked two holes on 3″ centers, centered vertically.  I selected a 1/8″ drill bit, which was slightly larger in diameter than the #8-32 machine screws used to secure the handle, and drilled the holes from the back side using a block of 2×4 as a drill guide to make sure I went straight through the board.  (A drill press would obviously have been the correct way to drill these holes, and I have one, but it is buried behind other things where I cannot get to it.)

I clamped the decorative base to the front of the pantry centered horizontally and vertically on the joint between the two veneered panels.  Using the handle mounting holes I drilled all the way through the front of the pantry.  I bought special handle mounting screws the other night that are 2″ long but can be broken off at 1/4″ intervals.  I needed a 1-3/4″ length, so I inserted the screws through the holes from the back and broke off the first section with a pair of pliers.  I screwed them into the handle, temporarily securing the block.  I then drilled four countersunk holes from the inside of the pantry into the back of the decorative block and secured it with 1-1/4″ self-drilling screws.  I left all of the other clamps in place while the glue dried.

The only thing I did not get done on the pull-out pantry was attaching the door stop to the bottom of the face.  I will take care of that tomorrow.

Linda called at 3:30 PM to let me know she was on her way home.  I started working on remounting the accelerator pedal.  I got the pieces of old tile that were installed in that area and used them as templates to mark the location of the mounting holes.

Yesterday I discovered a grease fitting on the steering column.  It is located towards the center front of the bus about 8″ up from the floor.  Joe has never put grease in this fitting when he has serviced the chassis and for all I know it may not have been greased since it left the factory.  I wanted to get some grease into this fitting before I remounted the steering column shroud but I did not have a grease gun so I put that on my next shopping list.

Linda got home a little quicker than usual due to lighter than normal traffic.  After changing into her work clothes and grabbing some pretzels for a snack she came out to the bus to help.  I set the accelerator pedal upside down on top of the brake pedal to get it out of the way and drilled holes at the three points I had marked.  Linda handled the vacuum cleaner as we are trying to keep the coach clean.  I set the accelerator pedal where it belonged and started the three lag screws by hand.  Linda then held the pedal up while I tightened the three screws with a socket and ratchet.  I also drilled a small hole for a screw to secure the cable clamp on the accelerator wiring harness and installed that by hand as there was no room for the Rigid drill/driver.

I did not want to install the steering column shroud until I had greased the fitting but I went ahead and installed the base bracket.  Again using an old tile as a template I lightly marked two of the five holes.  I removed the old tile, set the bracket in place, and lined it up with the two marks.  I then marked the other three holes.  I selected a suitable drill bit, smaller than the diameter of the screws, and drilled through the tile and a little ways into the plywood below.  The screws were 5/8″ pan head Philips so I installed them by hand.

It was finally time to install the two front seats.  We got the base/pedestals from the library and checked to make sure the paint was dry.  It was, so we moved them to the bus.  I was going to install the driver’s seat first but the 3/4″ holes I had drilled in the tile when I installed it were not big enough.  Actually, they were exactly the right size if they had been in exactly the right place.  I needed to enlarge them to 1″ but did not have a 1″ drill bit.  I added that to my shopping list and we proceeded to install the passenger seat.

I set the base over the four captive mounting bolts and put a large/thick washer over each one followed by a substantial lock washer and finally a nut.  I ran the nuts down by hand as far as I could and then used a socket and ratchet to snug them down.

By now it was half past dark.  We needed dinner and stuff for the bus so we headed to Lowe’s where I bought a 1″ twist drill with a 1/2″ shank.  We then went to the new Panera, on the same property as Lowe’s and Walmart, for dinner.  This Panera had a different look and feel than the older ones, which a much smaller bakery section, but the food and coffee were the same and were good.  After dinner I drove across the street to O’Reilly’s Auto Parts and bought a grease gun.

On the drive home I decided to defer greasing the steering column until tomorrow. Our priority was getting the driver’s seat installed.  I used the 1″ twist drill bit in our 1/2″ Craftsman drill to enlarge the four holes.  The base/pedestal has 1″ long alignment tubes on the underside so the holes in the tile and underlying plywood had to be big enough to allow for less than perfect positioning.  With the holes enlarged I dropped the base in place, set a large washer over each hole, and threaded the new bolts into holes in the structure of the bus.  That was the end of the bus work for today.  We retired to the basement recreation room and watched NCIS and NCISNOLA before going to bed.

 

2015/10/27 (T) The Pilot’s Seat

My morning started at 8 AM in its usual fashion.  I fed the cats, made coffee, started a load of laundry, made/ate breakfast (orange/grapefruit juice and granola with fresh blueberries), drank my coffee in the living room with the fireplace on and Jasper at my side, day-dreamed about high quality used Sony alpha lenses, and finally got to work on the bus a little after 10 AM.  Rain is coming tonight and forecast to stick around into Thursday so today would be a good day to do some more trimming, felling, and cutting up of dead trees.  The temperature this morning was still in the 40’s, however, and there is still much to be done in the bus.

A few days ago I installed a new AC outlet on the forward side of the cabinet behind the driver’s seat.  I wired it into the outlet on the aft side of the cabinet and then discovered that the original outlet was cracked.  I had also used an oversized cover plate on the new outlet and it interfered with the Corian cabinet top.  I finally got around to replacing the cracked outlet this morning.  I also switched the cover plates.  The regular size one still interfered slightly with the Corian top so I cut 1/8″ off of the top edge and added strips of felt on the three edges of the cabinet to raise the Corian top slightly and cushion it.  Everything fit nicely.  I turned the circuit breaker on and checked for power.  The outlets were good to go and I checked this mini-project off my (mental) project list.

I took a break and called the Escapees RV Club to register Linda and me as staff for the July 2016 Escapade.  I then called Josh at Coach Supply Direct regarding extra brackets for our MCD shades/brackets, the wiring of the passenger seat switch, and the correct orientation of the swivel bearings.  I learned that the flange, which wraps around the other piece on the inside of the ring, goes down.  (I had puzzled out that it should go the other way so I am glad I asked.)  When I was done with my phone calls I had a quick lunch of Sabra Roasted Red Pepper Hummus and Snyder sourdough pretzel nibblers.

My next task was unbolting the driver seat pedestal base from the floor.  The pedestal is secured by four large carriage bolts that go through holes at the four corners of the base plate and thread into nuts that I presume are welded into the floor structure.  The base had to be removed in order to remove the old vinyl floor tile which was installed under the base.  To get the old tile out I also had to remove a plastic cover around the steering linkage and a floor mounted bracket that retained the bottom if it.  Last, but not least, I had to unscrew the accelerator bracket from the floor by removing three small lag screws.  The accelerator is electrical, with a cable that runs through the floor, but other than limited access it was easy to detach.

Removing the old vinyl tile from the driver’s area of the cockpit was relatively straightforward.  It’s somewhat flexible and wasn’t glued down that tightly.  When Creative Mobile Interiors installed the tile they laid it out in a way that allowed the pieces to be trimmed in reasonable ways to fit around the steering column and brake pedal.  The brake pedal is mechanically linked to a complex multi-port air valve in the compartment under the floor and any finished floor has to be installed around it.

The plywood under the driver’s seat area was depressed directly under the base.  It seemed unlikely that this was the result of the base being bolted down.  It may indicate that this area also got wet like the area under the passenger side seat base.  I plan to install SurePly underlayment on the floor under the passenger seat but not the under the driver’s seat so I will either have to replace this piece or use floor leveling compound to fill the depressed area.  Replacing the plywood is probably the correct, but more involved, solution.

I started thinking about installing the new tile so I laid out all of the old tiles on the floor in the garage, kind of like putting a simple jigsaw puzzle back together.  I plan to use them as a pattern to cut the new tiles.  With a clear view of the whole driver’s area I became intrigued by the lower sidewall counsel next to the driver’s seat.  The more I looked at it the clearer it became that Royale Coach had cut the top off of a bumped out area, removed the upper three inches of the wall of the bump out, replaced the top piece, and tried to fill in the three inch gap in the side wall.  They had also cut out an access plate and then screwed it back in.  It eventually became obvious to me that they had done this to create horizontal space for the wide Villa driver’s seat that was in the coach when we bought it.  Had Royale Coach left the ISRI seat in place these modifications would not have been needed.  They were originally hidden under carpet but once the carpet was removed the really poor quality of the workmanship in this area was all too apparent.

I probably should have applied adhesive remover to the stairs and walls around the cockpit but it has to sit for 1 to 3 hours and the timing wasn’t right.  The weather was still decent and I needed to finish working on the trees at the west end of our property.  The adhesive remover can be left on for up the 24 hours so applying it at 5 PM with the intent of removing it the next morning might be ideal.  The weather forecast for overnight, through tomorrow, and into Thursday, however, is for rain and colder temperatures, so they will not be good mornings for working with the door of the bus open.

Around 3:30 PM I had a banana nut muffin and then called Phil at Precision Grading.  I got his voice mail and left him a message.  I was getting ready to use the chainsaw to cut down a small dead tree at the west end of the property when Linda texted that she was leaving the bakery.  A few minutes later Chuck called.  He had some carpet remnants for us and was nearby so he came over.  He could not stay long but took the time to look at what I was working on in the bus before he left.  It would still be awhile before Linda got home so I took the chainsaw to the west end of the yard, cut down the tree, de-limbed it, and cut it up into manageable size pieces.  I then cut up another tree of similar size that has been on the ground for a while and cut up some of the larger branches that I trimmed off the trees yesterday.

Linda got home while I was finishing the tree work and started fixing squash and a lentil/quinoa pilaf for dinner, both of which would take some time.  After cleaning the saw and putting it away I took one of the carriage boots from the bus driver’s seat and went to Lowe’s to see if I could find slightly longer replacements.  The old ones were somewhat rusted and some of the threads were in less than ideal condition.  The new Armstrong vinyl tiles are also a bit thicker than the old ones and I wanted to make sure I had bolts that were long enough to completely thread into the retained nuts.  It turned out that the bolts are metric, specifically M12-1.75×80.  Lowe’s had Grade 8 M12-1.75×90 bolts (10 mm longer than the 80s) so I bought four.  I also bought some thick M12 fender washers that were larger than the old ones.  While I was there I picked up a role of red electrical tape.

Dinner was excellent.  The squash was baked without butter (vegan) or brown sugar but was very tasty.  The pilaf had onions, garlic, and mixed greens and was very good.  We finished the Witch’s Brew wine from Leelanau Cellars that Linda used to poach the pears on Saturday.  The squash did not look that big, but neither of us was able to finish our half so we saved it for tomorrow’s lunch.

I checked e-mail after dinner and then we settled in to watch our Tuesday night TV programs.  We caught the weather report at 11 PM and then turned off the television and lights.  I turned down the brightness on my iPad display and worked for another 30 minutes before going to sleep.  I did not hear back from Phil this evening but I already knew he would not be here on Wednesday if the rain came as forecast as he had another job to work on that was better suited to working in rainy conditions than ours.

 

2015/09/25 (F) Miss Dig

I turned the lights out at 11 PM last night and slept until 8:15 AM this morning.  I was preparing coffee when Linda told me there were wild turkeys in the back yard.  They were gathered at the deer feed block and more showed up while we were watching.  There were 15 in all, and they were big.  We had our usual granola for breakfast with fresh blueberries, strawberries, and bananas.  We finished our morning routine and coffee at 10 AM and got back to work on the bus.

Linda continued working on removing the old wallpaper while I worked on the entry and cockpit.  She used a drywall sanding sponge to try and remove the last little bit of material from the walls she stripped yesterday and it worked rather well but not 100%.  I was able to remove the step well cover assembly yesterday and today I removed the last step before reaching the main floor.  It did not come out easily; the three screws securing it to two adjacent walls were badly rusted and the Philips heads would not hold the screwdriver bit.  I ended up prying them loose, and inelegant (brute force) but effective solution.  I am going to rebuild this step with a slightly deeper run and an open front so we can store shoes under it.  First, however, I have to tile the floor.

I spent some time examining the old tile in the driver’s part of the cockpit.  It clearly goes under the accelerator pedal but around the brake pedal.  That’s reasonable as the accelerator is electrical, with only a cable that goes through a small hole in the floor, while the brake is pneumatic and the major part of it is in the bay below the floor with all of the air lines connected to it.  I came to the conclusion that the tile was also installed under the seat base, which means Creative Mobile Interiors removed the base to install the tile.  I did not come to a final decision regarding removing the tile versus tiling over it, but I am leaning towards removing it.

I was also able to determine that the retaining nut on the swivel bases for the pilot and copilot seats was 15/16″ and accessible from the rear with the seats moved forward.  That means I can remove the seat, 6-way power base, and swivel plate as one assembly by removing one nut.  I will then have excellent access to the pedestal mounting bolts and the driver’s area once everything else is out of the way.

Rebecca from Shutz HVAC called at 10:30 AM and arrived about 15 minutes later.  Shutz is the HVAC installation contractor for the Lowe’s in Howell and she was here to look at our main air-conditioning system and give us a quote on a new Trane system as that is what Lowe’s sells.  Lowe’s had a Pro Show on Wednesday and Rebecca was staffing the Shutz table so we stopped to chat.  She let us know that everything at Lowe’s was on sale through tomorrow at closing for 10% off with our Lowe’s credit card, including installation labor.  The card is automatically good for 5% off on any product purchase so the extra 5% is not enough of an incentive to cause us to make the purchase, but we were curious what a new system might cost.  I will get a quote from Darryl at DCM, however, before making any decisions.  Also, our friend Mike (W8XH) recently had an A-C system installed and was very happy with the company, product, and installation so I will find out who he used and get a quote from them too.

Rebecca was very nice and very knowledgable.  After looking at the condenser/compressor outside I got a step ladder and she went up in the attic to look at the old air-handler/evaporator.  The system is a Coleman and we have no idea how old it is; we just know that it did not do a good job of cooling the house this summer.  The quote was for a “3 ton” system for $7,800.  With 10% off it came to $7,020 but that price was based on flushing, testing, and reusing the existing refrigerant lines, which did not sound like a good idea to me.

Charles from USIC (Miss Dig) showed up around 11:30 AM to mark the utilities.  Phil plans to start digging and grading next week, hopefully Tuesday.  Charles came to the front door and I excused myself from the air-conditioning conversation to walk the property with him.  I explained what we were having done and showed him where the work would take place.  He marked the main gas line along the entire length of our property, a portion of the branch line going to our meter, the tie in for the branch line to the house across the street, and the T at the northwest corner of our property where the main line splits to service the court.  He also marked the phone line, which runs underground from a pole west of our house to the southwest corner of our garage.  The main electrical service runs underground with the phone line but someone else has to come out and mark that.  I chatted with Charles briefly before he left and then called Phil and left him a message.

Last summer Darryl from DCM Heating and Cooling installed a new natural gas furnace with an air conditioner for our library, a natural gas heater in our garage, ran all of the black iron pipe, including 160 feet of 2″ line, hooked us up to the gas meter, and got everything working for just under $11,000.  The Trane system would be bigger than the one for the library, and the air-handler in the attic is a more difficult installation, but $7,800 for just the air-conditioner without new refrigerant lines seemed a bit high.  After Rebecca left I called and left a message for Darryl.

Linda was ready to strip the wallpaper behind the built-in sofa so we moved the two desk pedestals onto a blanket on the kitchen floor in the bus and unscrewed the seat and set it on top of the desk pedestals.  When I finally got back to work on the bus I removed the cover for the front OTR HVAC system and set it aside.  I was trying to get access to the underside of the wood trim that includes a grab handle that needs to be tightened but had a look around first.

I noticed a damper controlled by a flexible cable and figured it was what determined if the air was fresh or recirculated.  I turned the knob on the dashboard and saw the cable move but not the damper.  The damper was stuck so I loosened it by hand but the knob still did not cause it to move.  I then noticed that the sheath of the flexible cable had come loose from its retaining clip.  It was a tight spot in which to work but I was able to loosen the two screws holding the clip using a right angle screwdriver.  I slipped the sheath under the clip, tightened the screws enough to hold it, and turned the knob.  It worked!  On a day when I did not feel like I was accomplishing very much this was a tangible and unexpected success.

I removed the only four visible screws from the wood trim but it would not budge.  I had tried removing it once before without success but was determined to get it loose this time.  The only reasonable explanation was that CMI had glued it on after tightening the grab handle as part of the initial work we had them do right after we bought the coach.  I carefully worked a pry bar under the passenger side end and gradually applied force to it.  It was, indeed, “glued” on but it appeared that I would be able to pry it loose without breaking anything if I took my time.

When I did finally get it off I could see that they had used clear silicon (adhesive) caulk to attach it to a dark gray plastic piece.  Royale Coach had originally attached it to this plastic piece using four screws.  The plastic piece turned out to be the lower windshield defroster duct and I am considering how we might finish this without replacing the wood trim.  Wallpaper is currently at the top of my list but I doubt that it would be a good solution.  Of further interest to us was the wood itself.  We presumed it was maple based on the color but were puzzled why they would have used a different wood in the entryway.  Once we saw the back side, however, it was obviously walnut that lightened where it was exposed to light to the point of looking like maple.  There is other wood in the entry and copilot area that is equally light and we now realized that we had a refinishing task and not just a cleaning task, ahead of us at some point.

My next task was to scrape as much of the caulk off as I could.  I got a lot of it off, but not all.  Silicon caulk is difficult to remove.  I eventually found a single edge razor blade holder and blade and used that to get the last bit off.  I then worked on removing layers of masking tape from the edges of the base where the former step well slide was installed.

I have some carpentry to do to rebuild the steps and prep them for the tile installation and needed some materials and supplies so I went to Lowe’s and got:

  • Adhesive remover;
  • A 4’x8′ sheet of 3/16″ SurePly underlayment;
  • Two 3/4″ x 2.5″ – 6′ poplar boards;
  • A 15/16″ open or closed end ratcheting wrench;
  • A bottle of Piranha Wallpaper remover;
  • A Piranha wallpaper remover sponge;
  • A pack of 2,000 18 gauge 3/4″ long x 1/4″ crown staples;
  • A pack of 25 sheets of 120 grit and a pack of 25 sheets of 220 grit 1/4 sheet sandpaper.

I got 10% off the total bill! which was nice.  I did not get a palm sander as they were out of the Porter Cable model I wanted.  The Lowe’s in New Hudson showed two in their inventory so we will stop there tomorrow after breakfast and get one.  I also needed a half sheet of 3/4″ plywood to make a new platform to replace the step well slide but did not feel like dealing with that.

For dinner Linda heated some butternut squash ravioli she bought at Whole Foods.  She served it with sliced vegan Italian sausage cooked with mushrooms, onions, and garlic, a side dish of steamed fresh green beans, and a glass of Moscato.

After dinner I uploaded my blog posts for July 23 through 31 plus a gallery post of 11 photos I got from Jarel Beatty of the custom walnut desk in the process of being built in his shop.  I got a call back from Darryl and we discussed the new air-conditioning system.  He said he would get me a price but advised us not to let anyone reuse the old refrigerant lines.  If they are not 100% clean the old refrigerant will contaminate the new system.  If Shutz installs the Trane system it comes with a 10 year parts and labor warranty, but it would still be a hassle to deal with getting a contaminated unit repaired or replaced.

After chatting with Darryl for a while we agreed that there wasn’t any urgency to this.  For one, we need to have Darryl check the current system for leaks, and assuming it does not have one, for proper refrigerant charge, cooling capacity, and airflow.  Darryl is busy doing heating systems at the moment, but is willing to do the maintenance work.  Also, the cooling season is done for this year and we will be traveling during the hottest part of next summer.  A final factor is that this has been another expensive summer for us with the new roof on the house, the interior remodeling of our motorcoach, and the work Phil is about to do, so we would prefer to defer this expense.
