2015/10/16 (F) Desk Installation

We were up at 8 AM, fed the cats, made coffee, and had breakfast.  Phil showed up around 8:30 AM, unloaded his front loader, dropped his flatbed trailer, and left in his dump truck.  I turned on the fireplace and we enjoyed our coffee while iPading until 10:15 AM.

Our first task today was to cut up several large limbs that I pulled out of the woods last evening to get them out of Phil’s way.  I cut them up with the chain saw and then we stacked them on the disposal pile for Phil to haul away.

Phil returned at 10:30 and moved his Caterpillar 305C excavator into the woods across the street by the culvert.  I went down to chat with him briefly to make sure I understood what he was going to work on.  There were a lot of small trees (3″ diameter), saplings, and bushes scattered around the site.  Some of them had been dead for years and some had just been knocked over by Phil.  I decided to work in that area with my chain saw cutting everything up into five foot lengths so Phil could use his front loader to get them into his dump truck.  I worked at this until 11:30 AM and then turned my attention to the bus.  Linda worked on her needlepoint while I cut wood.

Before getting started on construction tasks I took two pieces of filter material and set them on the wire shelf in the freezer compartment of the new refrigerator, one on top of the other.  I then set the two remote thermometer sensors on the filter material.  Butch had suggested the other night that I set the sensor on a sponge to get it off of the floor of the freezer compartment as it was likely responding to the automatic defroster heat strips when they come on.  I figured the filter material would work just as well and that placing the sensors on the shelf would definitely get them away from the floor.

Linda brought out a bag of ice from the house fridge and put it in the bus freezer.  She also filled several 1/2 gallon juice and milk cartons with water, put the caps on, and put them in the fresh food compartment.  The purpose of all of this was to add thermal mass to the compartments to cause the refrigerator to run less often and reduce large swings in temperature.

Inside the bus our first sub-project was installing the desk, which included putting the front passenger side HVAC duct cover in place even though it is not finished.  It took us quite a while to get everything positioned just right.  With Linda holding things in position I screwed the right pedestal to the wall, adjusted the position of the base and screwed the pedestal to the base.  We then repeated that process for the left pedestal and base.

Linda removes the backing from the double-sided tape on the back side of the air grate in the center connector/cover for the desk.

At this point we had several things to do with, and under, the center connector/cover so I removed it and took it into the garage/shop.  We cut a piece of the decorative brass colored metal grate and secured it to the back of the air opening with small screws every few inches.  Next we cut a piece of black plastic mesh to fit over the grate.  We then cut pieces of 3M Extreme Mounting Tape (double-sided) and attached them to the back side of the grate in between the screws.  Linda peeled off the protective layer and we carefully placed the plastic mesh.  Using one of the scrap pieces of the protective layer I rolled the plastic into the take with our wallpaper seam roller.  Finally, we had a piece of filter material already cut to cover this air intake opening so we set that on top of the mesh, pressed it down to take advantage of the tape, and then secured it with Gorilla Tape on all four edges, rolling it with the seam roller to get good bonding.

Back in the coach I had to tie in the outlet strip to the 120VAC power feed.  I shut off the breaker for this circuit and checked with my tester to make sure it was not live.  The hot and neutral wires were accessible but the ground wires were back under the left pedestal where they were not easy to reach and manipulate.  It took a while, certainly longer than it should have, but I got the three ground wires tied together with a grounding clamp.  I connected the hot and neutral wires (three each) relatively easily using wire nuts.  I turned the circuit breaker back on and checked that the outlet strip had power between the correct terminals and did have power between any other terminal pairs.

I went to the garage to get a four foot long piece of 1″X1″ aluminum angle that I bought weeks ago to use as a support bracket for the upper rear edge of the center connector/cover.  I was going to cut off a 26″ long piece and then drill countersunk holes but I noticed a piece of 1/2″X1/2″ light gage angle that was about 26″ long and already had holes in it.  It was long enough to span the space between the pedestals and go under each one about an inch.  That was sufficient to position it correctly so Linda held it there while I secured it to the wall with four round (pan) head screws.  I then put the center connector/cover back in place.

Phil had long since left in his truck to dump all of the wood debris.  We had a light lunch of Amy’s Lentil Vegetable soup and fresh organic grapes.  While we were eating a group of three deer came to our back yard and eventually ended up eating apples that had fallen from our tree onto the ground.  These same deer, along with two others, were here yesterday at twilight and were very frisky.  We saw them later in our neighbor’s yard across the street.

Phil returned around 3 PM and started working on the French drain.  He replaced the 30″ wide toothed bucket with the 12″ one and started at the high end if the culvert on this side of the road.

The grand finale was the installation of the Corian desktop, which has been sitting on a blanket in the middle of the living area floor since Tuesday.  I drilled countersunk holes through the four corner plates in each desk pedestal from underneath.  I then inserted 1-1/4″ #8 self-drilling outdoor wood screws into each hole, again from underneath, until they just protruded above the corner blocks and then backed them off until the tips were just below the surface.  We set the desktop across the pedestals and pushed it as tight to the back and right end wall as we could.  Linda put her weight on it and I ran the screws home, pulling the top tight to the pedestals.  We reinstalled the four drawers in the right pedestal, finally getting them off the floor in the hallway where they have been since Tuesday.  We stepped back to admire the desk and agreed it was a thing of beauty and a joy to behold.  Linda also marveled, once again, at how much space she now has to work in the kitchen.

The “denouement” was mounting the outlet strip and adding felt pads to the two fake drawer fronts on the left pedestal and then adjusting the magnetic catches.  I originally had the outlet strip (temporarily) mounted to the wall between the two pedestals with two screws a few inches below the cord notch in the center of the back edge of the desktop.  Rather than put it back there I decided to mount it on the underside of the desktop just in front of the cord notch.

The underside location will work just as well as the wall mount location for regular 2- and 3-prong plugs but probably not as well for small AC adapters.  The added pluses of this location, however, are: 1) it will not interfere with cords coming through the notch, 2) it will be up out of the way of the UPS (uninterruptible power supply) that will sit on the shelf at the top of the center connector/cover, and 3) if liquids are accidentally spilled and run over through the notch they will not run into the outlet strip.  Besides, devices with an AC adapter will probably be plugged into the UPS so this was a better overall approach.

Our next task was to adjust the sofa seat until it was deep enough to be comfortable.  We slide the plywood seat out a couple of inches and then got the seat and back cushions (three each) from the house where they have been stored since September 21st.  We put the cushions in place and sat down.  We pulled the cushions out and pulled the seat board out until it was five inches farther out than originally designed and put the cushions back in.

The front edge of the seat cushions were out farther than I liked but we both agreed the sofa was now comfortable to sit on.  The distance from the bottom front edge of the back cushions to the front edge of the seat cushions was originally only 16 inches and that turned out to just be too short.  With the seat board moved out it will now be 21 inches.

In order for the sofa to work correctly, both as a sofa and as a bed, we will need a cushion that is 5″ wide by 6″ high, by ~76″ long to fill in the space behind the seat cushions and below the back cushions.  The height and foam makeup will be such that it is level with the tops of the seat cushions and have the same firmness and feel.  Would that I had designed the sofa for this depth to begin with and had the seat cushions made accordingly, but we were trying to open up the living room by not having the sofa protrude into the aisle any more than absolutely necessary.

Next up was reinstalling the wood trim in hallway.  We have an interesting plan for the lower half of the hallway but in case we do not get it finished before we leave for the winter we wanted the trim off the bed and back on the wall.

The lower outside hallway wall.  There were originally three framed panels of vertical strip mirrors here.  We will replace them with wood panels, probably in a lighter color to contrast with the walnut trim.

The lower outside hallway wall. There were originally three framed panels of vertical strip mirrors here. We will replace them with wood panels, probably in a lighter color to contrast with the walnut trim.

This trim originally framed three panels of vertical strip mirrors.  We were able to remove the mirrors as they were glued to wallpaper.  In the process we discovered that the left and right panels were the same width but the center panel was wider.  The trim consisted of six pieces of wood; a long upper and lower horizontal piece and four vertical pieces.  The six pieces were screwed to the lower half of the outer wall but not attached to each other.  The left and right vertical pieces were tight to adjacent woodwork, but the two intermediate pieces were free to be repositioned.

We reattached the upper horizontal piece first making sure the mounting screws went back in the same holes.  Next we pushed the lower horizontal piece into place but did not screw it to the wall.  We then attached the left and right verticals.  The horizontal distance between the inside edges of the left and right verticals was 75 inches.  The two intermediate verticals were each 4-1/2″ wide so the distance between verticals needed to be 22″ (75 minus 9 = 66 divided by 3 = 22).  We carefully positioned and secured the two intermediate verticals to achieve this spacing.

The trim boards all have rabbited edges on the back side.  I need to measure them carefully, but they are ~3/16″ deep by 3/8″ wide.  Our current plan is to use 3/16″ underlayment or other 3/16″ high quality plywood to make three panels that will fit within these rabbits with a little room to spare.  The panels will either have a hardwood face or we will cover them with a hardwood veneer of a wood that contrasts with the walnut trim.  We can get the veneer from Rockler once we decide what we want.

Linda spread out several towels on the new desktop and we moved tools and supplies from the A-V cabinet, behind the driver’s seat, to the new desk.  I then removed the Corian top of the A-V cabinet and put in on the bed.  We still have a small amount of wallpaper to install in the front of the living room and into the cockpit on the driver side, but it will not be easy to do.

These areas, such as the one behind the A-V cabinet, are small with limited access so most of my sanders cannot be used.  The only one that might work is the Porter-Cable oscillating tool but I did not get it out today.  I got some sanding sponges instead and tried those on the wall under the passenger side window trim next to the co-pilot seat.  When I sanded a dark area about 6″ long by 3″ wide the wood in the center crumbled and I ended up with a hole 3″ long by an inch and a half wide.  I could see one of the stainless steel structural members through the hole.  Given what was obviously water damage I was glad we bought a bus with welded stainless steel as the main structural material.

Based on what I could see, the walls in the bus appear to be 1/2″ plywood although I did not measure the thickness.  This area had obviously gotten very wet over a long period of time and some of the wood has rotted.  It is the only spot we have discovered that is this damaged and we immediately realized that we will not be able to wallpaper this area.  We will probably panel over it, similar to what we plan to do with the veneered panels in the hallway, but today was not the day to figure that out.

It was going on 5 PM and we decided we were done for the day.  I turned off all of the electric heaters, turned on the Aqua-Hot, turned on all three thermostats, and set the temperature to 20 degrees C.  The refrigerator was also indicating much colder freezer temperatures than it had been before I moved/isolated the remote sensors so I reset the freezer and fresh food controls to their “normal” center positions.  Tomorrow we will replace the alkaline batteries with the Lithium batteries we bought specifically for the TempMinder thermometer system, reset the min/max data, and monitor it for a few days.

I walked down to see what Phil was doing.  He was making good progress with the French drain but did not have enough of the plastic drain tile to finish it today.  He plans to work tomorrow and will have the additional tile he needs to finish the drain.  I left him to his work and took photos of the fall colors in our yard as I worked my way back to the house.

I spent an hour at my computer dealing with e-mail and transferring photos from the Sony a100 to my laptop.  Linda called me to dinner at 7 PM.  It was a simple meal of vegan Coney dogs with mustard, onion, and beans served open-faced on a whole wheat hotdog bun.  As a side dish Linda steamed Opo squash.  It was the first time either of us had this particular squash.  It was very mild with a hint of cucumber.  It is available all over the world and widely consumed as it is relatively inexpensive.  It was OK, but I thought it might work better as an ingredient rather than a stand-alone side dish.

I exchanged a couple of text messages with Chuck and confirmed that we would be at his shop tomorrow after breakfast to retrieve our two bus windshields.  The rest of the evening was spent in the living room by the fireplace reading and writing on our iPads before turning in and watching episodes of Rick Steeves’ Europe and Joseph Rezendo’s Travelscope on Detroit PBS (WTVS).

 

2015/08/25 (T) Turning The Corner

It got pleasantly cool overnight and with the bedroom doorwall open it made for nice sleeping conditions.  Between being up a bit late last night and not wanting to get out from under the warm covers we slept in a few minutes longer than usual.  I put on my sweats, which I find very comfortable on a cool (or cold) morning, and made a pot of Costa Rican decaf coffee.  We had our usual granola for breakfast, took a few minutes to enjoy our coffee in the living room without our cats, who were off somewhere and probably up to no good, and then got to work.

In order to install the new seats in September we need to have the desk installed and in order to install the desk we need to have the floor installed and in order to install the floor we need to have the underlayment installed and in order to install the underlayment we need to have several things done.  First and foremost was finishing the patching and leveling of the subfloor, so that was my first task today.  While I pursued that Linda continued working on cleaning and waxing the walnut drawer fronts.  Given the limited work surface in the garage Linda can only work on three to six drawer fronts at a time depending on their size.  When she reached a stopping point with those and started working on the woodwork in the bedroom.

I have spent the last week patching, skimcoating, and sanding the entire area where the old tile was installed which I estimate to be about 80 square feet.  I went over it one more time this morning with 80 grit sandpaper on the orbital sander.  The sander has an integral dust collection bag so it did not get the coach too dusty.  I was satisfied with most of the job but still had some unevenness along the edges by the walls and especially in the toe kick spaces extending out about three inches from the cabinet bases.  That is because I did not get the last skimcoat as smooth as I needed to in those areas and the orbital sander cannot reach them.

 

I figured I would need to do one more application of floor leveling compound but did not want to open the second bag of mix for such a small job.  I decided to go the Lowe’s and buy a small pail of pre-mixed floor patching compound and the 3/4″ #8-32 machine screws we needed to install the new handles.  While I was there I noticed that they had 50 grit hook and loop sandpaper triangles designed to fit our Porter-Cable oscillating saw.  I was aware that we had a sanding pad attachment for the tool but had not considered using it until I saw the 50 grit paper.  I bought a pack and picked up some 120 grit as well.  I would also have bought 80 grit but they were out.  I had to go to The Home Depot for the machine screws as I wanted the same brass ones we had already purchased.

Back at the bus I decided to try sanding out the imperfections rather than filling them in with another round of patching and sanding.  I was, admittedly, tired of this phase of the work and anxious to be done with it so I could move on to next step.  August is slipping away and I am very aware of the date.  I was also not keen on creating more sanding dust inside the coach.

I don’t know why I did not try this tool sooner.  The design of the tool and shape of the sanding pad allowed me to work in the all of the areas the orbital sander could not reach and it worked very well with the 50 grit sandpaper.  The circular air sander can also reach these areas, and was the right tool for grinding down the old thinset and mastic, but the oscillating tool was the right one for this final smoothing.

When I thought I was done I vacuumed the floor and used the Revel Damp Mop to pick up any residual dust.  We then went inside to have lunch while the floor dried.  Linda heated up a can of Amy’s vegetable soup, made roll-up sandwiches, and served fresh black grapes and plums.  It beats fast food hands down.

After lunch I inspected the floor carefully and decided that the patching and leveling was done.  Although it was one task out of many, and there was no fanfare attached to the moment, I was very much aware that we had finally turned the corner.  We still have some minor disassembly to do, but from this point forward most of our tasks will involve putting the interior back together and installing new things.  All things being equal (which they never are) the building work should be more fun than the deconstruction work.

The major exception is the wallpaper.  We still need to remove the old paper, much of which is stained from old water leaks, and install the new paper, which Linda will be ordering tomorrow from Delux Drapery and Shades in Ann Arbor.  The critical pieces are the ones that go behind the desk and the built-in sofa.  Most of the rest of it can be finished later but we would prefer to have it all done by September 12th if possible.  The more stuff that gets installed the more awkward it will be to work on the walls.

With the floor leveling done the next impediment to installing the underlayment was getting the refrigerator out of the living room and into its alcove.  That, however, required three other things to be done.  First I needed to replace the electrical outlet with a recessed one.  Second, we needed to build up the base of the alcove and finally, we needed to install the pantry as we cannot get to the slides to mount them to the side of the alcove with the refrigerator in place.

The electrical outlet only took a few minutes to change.  With Linda’s help I used the template I made last Thursday to cut the base pieces from the 4′ x 8′ sheet of 3/4″ plywood we bought on Tuesday.  The bottom piece was the full width of the refrigerator alcove (34″ wide at the front and 33.75″ wide at the back) and 25.75″ deep.  We set it in place, checked the front setback, and screwed it to the subfloor.  The next piece was the same width as the first but 1/2″ deeper (26.25″).  We set it in place on top of the first piece and made sure the front edges were flush with the back edge extending 1/2″ farther back.  I used longer screws to go all the way through both pieces into the subfloor.

I was not happy with the way my circular saw blade was cutting and a few raindrops gave us an excuse to take a break.  We were working just outside the small garage bay and moved everything into the garage to keep it from getting wet.  I went to Lowe’s and bought a new 7.25″ blade with 60 teeth, which should give a very clean cut through plywood but still work on 2x4s and trim boards.  While I was there I checked their selection of driver bits again.  I was looking for a 3″ long No. 1 SR (square recessed) bit but they did not have any that long.  I found a 2″ bit for $2.48 but then I spotted a pack of seven 2″ long bits for under $4.  It had two #1, three #2 (the most common size), and two #3 bits from the same manufacturer as the single bit.  Can someone explain that pricing structure to me?  Apparently most of the cost is retail packaging.

Linda prepared large, wonderful salads for dinner.  She made her own dressing using balsamic vinegar, walnuts, raisins, garlic, and seasonings, and it was very good.  We finished the Pinot Grigio with the meal and then resumed our work.

I changed the blade on my saw and then we moved the wood and 2×4 supports back out into the driveway.  The new blade made very clean cuts confirming that changing it was long overdue.  The third piece of the alcove base was not as wide as the first two, measuring 28.25″ across the front and 28″ across the back.  (The alcove tapers in 1/4″ from front to rear along the right side.)  The depth was 26.75″ to match the refrigerator base depth, and a half inch deeper than the second piece.  I set it in place, snug to the right side of the alcove and flush with the front edge of the other two pieces, and checked for an even reveal along the left side of 5.75″.  Everything looked good so I screwed it down.

There are several reasons for this design/construction.  First, there is a large bundle of wires and two air lines that run across the floor of the alcove at the rear wall.  Using three layers of plywood allowed the top layer to be high enough for the base of the refrigerator to extend over the wire bundle and have its back about 1″ from the back wall (thus the reason for the recessed electrical outlet).  It will also leave about 1″ of clearance above the fridge, which is enough.  The second reason is that the 5.75″ width at the left, with only two pieces of plywood under it, is where the pull-out pantry will go.  But third, I will install a 24″ long 2″ x 2″ angle (steel or aluminum) on the middle sheet against the left edge of the top sheet to prevent the refrigerator from shifting to the left.  The front edges of the plywood base pieces will be covered (eventually) by a something, probably a piece of 3/4″ thick walnut hardwood, that will stick up above the top surface of the top piece just enough to keep the fridge from rolling out.  That piece, however, will have to be removable so I am still thinking about just how I want to secure the refrigerator case in the alcove.

We still had some light but with the heavy cloud cover it was darker than usual in the coach for this time of day (6:30 PM).  We rigged up a piece of twine to hang the work light and turned on as many interior lights as we could.  We then carried the pull-out pantry from the library (in the house) to the bus.  We brought all of the slides in as well, along with two pieces of 3/4″ plywood and a 4′ length of 2×4.

We set the two pieces of 3/4″ plywood in front of the left edge of the alcove flush with the two bottom base pieces.  We then set the 2×4 on flat (3.5″ side down) spanning the plywood inside and outside the alcove.  We installed the cabinet halves of the nine slides onto the pieces attached to the pantry and then set the unit in place with the bottom resting on the 2×4.  We moved the pantry in and out checking its position and considering where the slides needed to be attached to the alcove wall and exactly how we would do that so the front has an even reveal relative to the vertical front trim of the left alcove wall.

By this point it was after 8 PM, it was getting dark, and we were too tired to start something as critical as attaching the slides to the alcove wall.  We are behind schedule, but had enough sense to not push beyond our limits.  We closed up the bus, relaxed on the couch for a bit with our kitty cats, took some Advil PM, and went to bed at 9 PM.
