2015/11/16 (M) Tiling the Cockpit, #3

Linda planned to go to the bakery today but decided yesterday to stay home and help me instead.  Based on the 10-day forecast this looks like our last decent weather day to work on the bus and we wanted/needed to make the most of it.

We had breakfast at 8 AM (granola with blueberries and a banana) and had a cup of Stash China Black tea.  I had a text message from Kristine Gullen regarding getting together with her and Jim on Saturday and replied in the affirmative.  We finished our tea by 8:30 and got to work.

I really wanted to finish tiling the cockpit of the bus, or at least as much of it as we could.  That meant cutting and fitting tiles for the stair treads and risers and the two side walls of the entry steps, gluing them in place, and then grouting all of them.  We needed to mount the table if possible and I also needed to build a new step for the platform.  That was a lot to get done in one day and even before we started I doubted that we would get it all done.

When we opened the bus we were surprised to find that the tiles on the walls of the platform had slipped all the way down to the floor tiles.  Obviously I should not have removed the spacers right after installing the tiles and should have to left them in place for any horizontal grout spaces on vertical surfaces.  Oh well, not much to do about it now.

Keith called to see if he should come and mulch the leaves one last time.  The weather the last few days had been very nice, unseasonably warm and dry.  Today was also a beautiful day but the forecast going forward was for much cooler and wetter conditions, so this was an ideal day for our last lawn mowing of the 2015 season.

We measured and cut the tiles for the face of the platform and out to the door.  At that point I evaluated what I needed to do to complete the job.  Basically, I needed to cut all of the tiles for the entry steps and walls and then install them from the bottom up.  Every piece of tile was going to be smaller than a full 16″x 16″ tile and custom cut so even though the square footage was not that much there would be more pieces than usual and it was obviously going to take quite a bit of time to get all of the pieces ready to install.  I thought we could be ready for adhesive in two hours but Linda figured it would be at least three.  It also meant working with the door open which would make it difficult to keep the interior as warm as we needed.

Phil showed up with his excavator and a dozen bales of straw.  I knew the excavator was for a different job as he did not have anything left to do at our place that required it.  He was here to finish covering the topsoil and grass seed with the straw.  We took a break to go talk to him and confirmed that he was done with the driveway and French drain projects except for the straw.  He staged the bales where he needed them but said he had to leave to dig a perk test hole at 1:30 PM and would be back mid-afternoon to finish spreading the straw around.

Linda suggested that we go ahead a grout all of the tile we had already installed.  I was more emotionally invested in completing the tile work than Linda but had to agree that this was the prudent thing to do.  Until the tile was grouted we could not reinstall the accelerator, the steering column shroud, the seat bases, and the seats, so grouting the tile was clearly a critical path item and that is what we did.  It was after noon by the time we finished so we took a break for lunch.  Phil had taken off by this time to go dig the test pit.

Lunch was grilled vegan Italian sausage on a bun with mustard and relish and black grapes on the side.  Keith finished up mowing the yard while we were enjoying a cup of Rooibos tea.  We paid him and chatted about next year.  I gave him our approximate timeframe for returning home from Florida and asked him to go ahead and start mowing next spring whether or not we were here.  We have had Keith take care of our lawn since we bought our house in the country and he has been very good about doing that when we are away and allowing us to catch up with him when we get back.

By the time we got back to work on the bus it was after 1 PM and I had to concede that we were done working on the tile until next spring except for cleaning them, which had to wait until tomorrow as the grout has to cure for 24 hours before final cleaning.  With that decision made we considered what else needed to be done and in what order.

The first order of business was painting the two front seat bases black.  We spread out painter’s plastic on the driveway and taped it down.  We set the bases there and then masked off the top portion with the swivel bearings and mounting bolt.  We wire brushed the bases to remove rust and then went over them with a sanding sponge.  I used a cleaner/degreaser and water to clean them and then gave them a coat of black rubberized undercoating paint.

The next order of business was getting all of the tools and materials that we no longer needed out of the bus to give us room to work on other things.  On Saturday I re-installed the bump out on the walnut cover for the passenger side HVAC duct.  The duct needed to have two 4″ holes drilled in it to match the holes in the metal duct, so that was the next task.  I measured very carefully and transferred the measurements to the face of the cover with equal care.  Even so, I was off slightly and had to use the sheet metal nibbler to enlarge the bottom of each hole.  At least I had a relatively straightforward way to fix this problem; I am not always so lucky.

With the holes enlarged we put the cover in place.  The 4″ round plastic registers fit through the wood into the duct but not all the way due to two tabs.  I trimmed the tabs off using the Porter-Cable oscillating saw and trimmed a little bit off of one of the outer mounting flanges to make it fit flush.  I drilled holes through the two mounting holes on each register using the #5-6 self-centering drill bit and secured them with #6-5/8″ SR screws.  We then removed the two temporary black plastic registers from the front of the built in sofa.  I trimmed the tabs off of two new brown ones and installed them using the same procedure as the first two.

In the grand scheme of things getting the cover in place and the four registers installed was a small task but it needed to be done and stood in the way of other things.  The cover has been stored on top of the two front seats, which have been lying on their backs on the kitchen floor of the bus for weeks.  We plan to re-install the seats late tomorrow afternoon.

Two more small, but critical, tasks were securing the pull-out pantry and the refrigerator.  I have assumed for quite a while that we would secure the pantry for travel with some form of sliding latch but had not thought about it in any detail.  We also needed to secure the refrigerator but I had not thought about this in any detail either.  As we pondered the pantry latch it slowly became obvious that we did not have enough wood for a strike plate to receive a pin and we did not have two unobstructed surfaces that were in the same plane, which would be required for the kind of latch I had been thinking about.

As for the refrigerator, one of our bus nut friends secured their unit by running mounting bolts (machine screws) through the floor of the cabinet above the fridge and threading them into the unused tapped holes provided for the upper door hinge (if it was reversed) .  After looking at it for a while we realized that we could attach a section of small angle to the inside of the right alcove wall with the other side just against the face of the fridge case but not over so far as to interfere with the door gasket.  My measurements indicated that a 1/2″x3/4″ angle would be just right.  It looked to me like two 12″ pieces, one by the freezer door and one by the bottom of the fresh food compartment door, would be more than adequate to keep the refrigerator from rolling out as it cannot shift sideways or twist due to the aluminum angle on the left/hinge side at the floor.

About this time Phil returned in a red pickup truck.  He finished distributing the straw and loaded three unused bales into the back of his truck.  He pulled up in the main drive and we invited him into the bus to see what we had been working on all summer.    It is always a pleasure working with Phil.  If/when we build a barn we will have him do all of the site prep and finish grading.  He will figure out the final cost for the driveway extension and French drain and send us an invoice.

Linda prepared an easy but tasty dinner consisting of a nice green salad, mixed frozen vegetables (corn, peas, and carrots) suitably reheated, and mac-n-cheese that was both dairy-free and gluten-free.  After dinner we went to Lowe’s and The Home Depot.  At Lowe’s we bought a 1/16″ thick 1/2″x 3/4″ aluminum angle and three 8 foot lengths of brass colored nose edging but did not find a latch that we liked.  At The Home Depot we bought some screws for securing the handle on the front of the pull-out pantry and a solid brass door stop to keep the pantry in place.  The door stop folds up when not in use and should work to keep the pantry closed while traveling.

Although the new Panera on the southwest corner of Grand River Avenue and Latson Road was finally open for business we stopped at Teeko’s Coffee and Tea on the northeast corner of that intersection.  Jeff was there and took our order for eight pounds of coffee beans.  We got two pounds each of Ethiopian Yirgacheffe, regular and decaffeinated, the Seattle Blend (regular), and the Sweet Dreams blend (decaffeinated).  They will roast the beans and then let them outgas for a few days before vacuum sealing them in half-pound portions.  This allows us to take them with us in the bus and keep them very fresh until we are ready to use them and to change what we are drinking more often.

We got home just after 8 PM and took our iPads downstairs to use while we watched our Monday evening CBS TV programs.  We caught the weather forecast and then headed to bed.  It looks like we will have two more days with unseasonably high temperatures near 60 degrees F but with intermittent rain and then a serious cooling trend with highs this weekend barely above freezing.  Our time for working on the bus and being in Michigan is definitely running out.

 

2015/10/17 (S) First Snow

Last night we removed the dining table from the back of my car and put it on the bed in the bus.  We then removed the two rear seats and put them in the garage.  We wanted the back of the Honda Element empty when we got up this morning as we do not usually have time to spare in the morning before driving to South Lyon for breakfast with the South Lyon Area Amateur Radio Club.

It’s always good to see our fellow hams and today was no exception.  We arrived just before 8 AM and stayed for over an hour.  We left around 9:15 and drove to Chuck’s shop in Novi to get the box with the two remaining lower windshields for our bus.  Chuck was already there and helped us load the box into the car.  The box was sized to hold five windshields but only had two in it so it was light enough for us to move by hand.  I knew it would fit in my car as we had measured it on a previous visit and I had checked the dimensions against the car.  We set one end on the tailgate, lifted the other end, and slid it in.  We chatted for a while, and looked at a project Chuck is working in for new front window shades, before heading home.

Phil was not at our house when we got home but he had obviously been there.  All of the concrete, and many of the rocks and boulders, were gone from the driveway extension area so I presumed he had loaded them in his truck and hauled them away.

The Converted Coach Owners (CCO) Halloween Rally was going on this weekend and today was the main day for activities.  We had intended/hoped to go to the rally but the progress on our bus remodeling has slowed over the last couple of weeks for various reasons, all legitimate, and it was not in a condition to travel or be used.  It’s not that things are not getting done; they are, just not as fast as we would like or need them to.  Among other things I have not yet secured the refrigerator and pantry.  We thought about driving over in the car but it was over two hours one way and we needed to spend what time we had available working on the bus and could not justify being gone.  Thanksgiving does not look/feel that far away anymore.  It also seemed ill-advised to be gone while Phil is here digging up the yard.

My main bus focus for today was completing the installation of the built-in sofa.  We had already set the plywood seat board on a blanket on the bus kitchen floor so I had access to the inside of the base/storage box.  I did not need Linda’s assistance for a while so she worked on her counted cross-stitch project.  Before starting on the sofa, however, I took care of a few other minor things.

First I replaced the alkaline batteries in the TempMinder thermometers with Lithium ones.  I then reset the minimum and maximum temperatures for the two remote sensors.  Sensor #1 monitors the freezer and sensor #2 monitors the fresh food compartment of the bus refrigerator.  The directions for the TempMinder suggest using Lithium batteries if the remote sensors will be in cold environments.

Next I got a piece of scrap SurePly underlayment to see how it would fit in the rabbited wood trim on the lower outside wall of the hallway.  I inserted it fully into a corner and marked the edges with a pencil.  It is approximately 3/16″ thick and fit nicely without being too tight.  With a layer of veneer it should be just right.  When I removed it the depth of the rabbits appeared to be 5/16″ to 3/8″.  I think the underlayment will make a nice base for hardwood veneer.  I will cut the panels 1/2″ wider (22-1/2″) and 1/2″ longer (28″) than the 22″ X 27-1/2″ dimensions of the framed opening and allow them to “float” just like a frame and panel door.

My last mini-task was locating the 1/4″ walnut veneered plywood we removed from the old refrigerator and measuring it to see if we had pieces big enough to panel the damaged area on the wall by the co-pilot seat.  I was pleased to find that the remaining pieces are large enough for this application.

By now it was 12:30 PM and my phone reminded me that we had an RVillage Ambassadors webinar/meeting at 1 PM.  Linda heated up some Amy’s Vegetable Bean Soup and made hot lentil loaf sandwiches with ketchup.  Yum.  We got our first snow flurries of the 2015-16 winter season during lunch and they continued off and on through the afternoon.  We moved to Michigan in May 1976.  It snowed on October 15th that year and we had snow on the ground every day until early April 1977.  While that has not held up over the years as a “typical” southeast Michigan winter it was very different from what we grew up with in Missouri and formed our first and most lasting impression of our adopted state.

I retrieved the link for the Go To Meeting from the RVillage website and put it in my web browser.  1 PM came and went with no meeting.  The meeting notice said “Saturday, October 17 at 10 AM PST” but they had clarified that was actually 10 AM PDT, which is 1 PM EDT.  We decided that perhaps they really meant PST, which would be 2 PM our time.  We tried again an hour later, but no meeting ever commenced.

When I finally got to work in the bus on the sofa I removed six screws, three each from two angle brackets, and pulled the entire base assembly out from the wall, giving me complete access to the HVAC duct and wiring chase.  Much of the final installation of the sofa involved this duct.

The ends of the plywood seat rest on two boxes with open ends that also serve as plenums for air from the OTR HVAC system ducts.  I needed to cut out rectangular openings in the vertical face of the duct to allow air into the back end of these boxes.  I used a 1/2″ drill to create starter holes at the corners of the openings and then used a manual sheet metal nibbler and a drill-powered reciprocating nibbler, both of which I borrowed from Chuck a few weeks ago, to cut out the sheet metal.  The two tools work differently but they both worked well and I was glad I had both of them for this task.  The powered nibbler created a lot of small metal debris so I vacuumed the whole work area very thoroughly when I was done nibbling.

The right (forward) end of the duct also had an extra hole in it where I did not need or want one.  I removed an old sheet metal patch plate and cut a new one to cover the area I needed to close off.  I ended up having to pre-drill holes as I spun the heads off two of my cheap sheet metal screws.  I had a heck of a time getting the shafts out, but I got it done.  This was just one more example of why seemingly simple projects always take longer than they should.

Phil returned while I was working on the sofa and continued trenching in the French drain.  I stopped to chat with him briefly and Linda came out to let me know she was headed to the grocery store.  I then got back to my own tasks and let Phil get back to his.

The left support/plenum box with the circular register hole cut in the face plate.

The open fronts of the two plenum boxes are attached to the inside of the vertical front support, which is 3/4″ walnut veneered plywood.  To get the air out of the boxes and into the coach my design called for brown plastic 4″ round louvered diffusers.  They are considered “four inch” because the two inch long cylindrical pipe on the back will just fit through a 4″ diameter circular hole.  (A 4″ flexible duct, like dryer duct, will also just fit over the pipe.)  The visible part of the diffuser is actually 5-1/2″ in diameter.

The inside width of the plenum boxes is 4-1/4″ by design.  I needed to center a 4″ hole within that space so I had to locate the center point for my 4″ hole saw very accurately side-to-side.  I also wanted the hole centered vertically.  Using my small square I marked the vertical midpoint on the edge of the front plywood at each end.  I then measured in 2-13/16″ from the midpoint mark and used my spring-loaded center punch to mark the center of the hole.   [The 2-13/16″ dimension came from half the inside width, or 2-1/8″, plus the thickness of the plywood used to make the plenums, or 11/16″.]

I stood the boxes on their back ends so the front board was horizontal.  I straddled the front board with my legs to hold it and drilled starter holes with a #6 countersink bit.  I then drilled the 4″ holes with a 4″ hole saw using my 1/2″ Craftsman corded drill, being careful to have the pilot bit in the starter holes and drill perpendicular to the face of the plywood.  I have had this drill for 37 years.  It is very powerful and has several ways it can be gripped quite securely.  It is large, heavy, and lacks the convenience of a cordless drill but when I need to use a bit with a 1/2″ shaft and/or need the torque, this is still the drill for the job.  The hole saw created some sawdust so I vacuumed the whole area thoroughly when I was done drilling.

I was just finishing this work when Linda got back from the grocery store.  She put the groceries away and came out to see if I needed any assistance.  I already had the roll of plastic screen in the bus and she got the Gorilla Tape from the garage.  I cut pieces of the screen large enough to cover the two rectangular openings in the HVAC duct and used lengths of Gorilla Tape to secure them.  We then slid the base/storage assembly back into position, pushed it tight to the HVAC duct, and reattached it to the wood wire chase on top of the duct.  The two support boxes and the return air box have foam weather stripping on the back edges to seal against the duct.

We picked the plywood seat up off of the kitchen floor and set it back in place but did not secure it.  We left it out several inches from its original position and got a seat and back cushion from the bedroom.  We experimented with different spacings and finally agreed that we need to have the seat out 4-3/4″ farther than originally designed.  The current hinge board is 11/16″ plywood, 2-3/4″ wide by just under 78″ long.  This board is screwed to the top of the wiring chase and to one side of the 72″ piano hinge.  I will replace it with a piece that is 7-1/2″ wide by the same length.  I will also have to provide some additional support for the seat side of the piano hinge as in the original design had both sides of the hinge resting on top of the wiring chase on top of the HVAC duct.

That was the end of the interior bus work for today.  By the time we were done Phil had driven his front-loader onto his flat-bed trailer and secured it so it appeared he was wrapping up for the day.  I chatted with him about the project for 30 minutes before he left.  Earlier in the afternoon I had found my site plan drawings for the bus barn and agreed to stake out the driveway tomorrow so we could review it first thing Monday morning.

Linda had invited Meghan and Chris for brunch tomorrow but it was not a good weekend for them as the Michigan vs Michigan State football game was taking place in Ann Arbor.  Chris manages the Pizza House restaurant, and being away on football Saturday is not an option.  They will come next Sunday (31st) instead.

For dinner Linda made a nice salad of mixed greens with dried cranberries, sliced almonds, and diced onions dressed with raspberry vinaigrette.  The main course was pan-fried polenta with vegan puttanesca sauce.  It held its heat to the last bite and was very satisfying on a cold evening.  I opened a bottle of Cupcake Black Forest red wine.  We have had it before and, although drier than I prefer, it went well with the meal.

After dinner I got my flashlight and checked the bus for axle/hub seal leaks by looking under the bus from the opposite side to see the inside of the wheels.  I did not see anything to suggest a problem on any of the six positions and will text that information to Joe tomorrow for planning purposes as he would require a second day to work on the seals if that was needed.

We spent the last couple of hours of the day in the living room, with the fireplace turned on, reading, writing, and playing games while enjoying some red grapes for dessert.  Linda got a text from her sister-in-law, Mary, with a photo of her and Ron “standing on ‘the’ corner in Winslow, Arizona.”  Ron has been retired for many years but Mary only recently retired and they are on their first extended camping trip in their A-liner trailer and their first trip to the southwest U.S.

We went to bed around 10 PM.  Linda fell asleep quickly while I divided my attention between cooking shows on the Detroit PBS Create channel, a concert by Eric Clapton on PBS, and working on this post.
