Light Mounts and Miscellany

The teardrop build continues, and in short fashion since that last update. Maybe it's the summertime blues or the oppressive heat and humidity that veers me towards working in the cool(er) garage rather than mountain biking. I'm also a bit worn out during August due to work in higher ed. technology and need a side project.

I cut the remainder of the light reinforcements on the jigsaw and mounted the two near the front of the teardrop. Here they are, just glued and clamped down:

The light fixtures will screw upward into these blocks, holding the entire mess together. I opted for more burly screws than the ones packages for this task.

I then added the insulation across the entire section, cutting to fit around the blocks. Here's a closeup and a wide view.

I knew those odd sections of leftover insulation would be useful. I stalled at the light reinforcements due to only having four small clamps (you can never have enough clamps) and moved on to some other miscellaneous work. I added two more coats of polyurethane to the underside of the "rear flap" of the cabin headliner that protrudes into the galley. Below, you see the galley perspective and the flap that will fold over the sliding cabinet area of the galley.

This area will feature two sliding doors, left to right, where food items, rather than screws, will store. For this build, I intend to build a shelf that will split the vertical difference, providing additional room for plenty of supplies.

There are a number of tasks to do next in the near future. Behold, this list:

• Install the rear interior light fixture reinforcements
• Install the insulation on the panel with the rear interior lights
• Finish the interior headliner with sanding and polyurethane
• Cut out the section of the headliner for the roof fan
• Install the galley 2x2 spar that will push the "flap" of the headliner down and thus seal the cabin
• Run wiring out of the front light fixtures and install the outside skin over the front curve and the fan section
• Or any other number of items in some other order

Of course, this is a lot of fun for me, and a great diversion. Until the next update, cheers.

Lights and Skin

I was on standby for work last weekend, which means I actually had a weekend where I was mostly home. That makes for a good weekend of building stuff! I picked up a 4x8' sheet of 1/4" birch plywood and a few other bits from Home Depot and set my sights on installing a piece of the outer skin and working on the interior lights install.

Outer skin came first. The garage is open for business, and I'm cutting the lower front outer skin. It was a bit wider than spec, so I adapted. This piece is something like 30 inches tall. I'd tell you precisely, but I'd have to rip the front skin off, as I'd written the notes on the inside.

This is the lower front section is its complete form. I've applied a weather proofing agent to both sides. The product is sourced from The Rot Doctor, and online retailer, and is called Clear Penetrating Epoxy Sealer (CPES). It's expensive, but builders swear by it. You can certainly feel the difference, the wood feels harder, which is quite evident if you've applied it over pencil markings and you try to sand them off.

The front of the teardrop will take on a good amount of weathering during travel, so this is key. Part of this is also treating the bottom inside of the panel that rests against the metal trailer frame with roofing tar. This stuff dries very hard and makes a great wood seal. You see this application below.

Here is the panel installed in the below photo. The bendy parts are up to come, as the next section up will be installed after the front cabin lights are in.

Like many things, the cabin lights install is part of a series of prerequisites. I want to at least polyurethane the inside headliner around where the fixtures will sit. Sanding before that. Really, I should just finish the interior headliner with a full sanding and polyurethane treatment. Regardless here is the process for installing these particular lights. Below are my placement measurements: 7" from the sides and splitting the headliner segment at 4.5". This could vary for preference.

Below, I partially disassembled the fixture so I could use it as a template of sorts.

I now cut out a keyhole-like hole in the headliner to accept the orbital portion of the lamp as well as the wiring/switch connector bit.

The next two photos are of a reinforcement for the assembly. The lamp screws into the wood as a surface mount, but 1/4" plywood does not provide much to grab onto. Pivoting the lamps, as they are designed, will eventually loosen up those screws. This block of wood will allow the screws to chew into something more substantial and also provide a boundary to butt the insulation up against. The open side allows for the switch/wiring block and also makes it easy to cut with a jigsaw.

That's it for the weekend. There was some good progress here, and hopefully I can get some more time into this in the coming weeks. Next, I'll cut the remainder of the reinforcement blocks and tack them down with some Gorilla Glue, waiting to screw the light housings into them from underneath. And then there're many directions I could take: sand and polyurethane the headliner, cut out the ceiling fan section, work on the galley... you get the idea.
