Teardrop Trim, Wiring and More

I was on vacation last week, so there's been plenty of teardrop activities to discuss. This was a staycation with the direct purpose of accelerating the teardrop build. The tongue box is almost finally complete, it became a project just on its own.




It's now fully installed, with four mounting points on the metal frame rails. I had spent a bit of time looking for pre-fabricated boxes on the internet and couldn't find anything that met my specifications. I wanted a perfect spot to place the deep cycle battery, jacks, wheel chocks among other things.




This above is the interior of the tongue box, and a shot of the battery box in its mounted location. I've mounted it a bit off-center to allow for a small propane tank.





Above, the battery is in place with the battery box lid in place. I have a 20 amp main breaker in place above that for full system shutdown. I moved onto the cabin wiring again while I had the electrical tools in my tool belt. I wired in the 12-volt receptacle to the electrical raceway door, shown below, running wiring to the fuse box, ground bar and main bus bar.




In all its chrome glory, you see it below. It also works, which is always pretty fantastic.




To the left of the outlet in the photo above lives another receptacle slot that's designated for a household 110v receptacle tied to an inverter. I'm pushing that down the road a bit, I can only order so many parts at a time.

That brings me to the fenders that just came in from etrailer.com. Keeping with the accent motif, I'd ordered a pair of aluminum fenders in diamond plate.





Above is one fender on the workbench along with two side doors with a fresh coat of polyurethane on the inside surface. I sanded and cleaned up those surfaces earlier this week. The inside surfaces received two coats of poly, ultimately.

I had the fenders shipped in with the goal of installing them last week. Mission accomplished, as you can see below.






I had to pop the wheels off to install the fenders. I drilled five holes in the sides and mounted them directly to the walls of the teardrop with 3/4" screws. Note that I will be replacing the white wheels with alloy wheels and radial tires, which should fit the overall look better.

The next area to be tackled was the hatch weatherstrip, which is a trial and error endeavor. I settled on a solution for the hatch-to-side-wall interface that utilizes two different thicknesses of weatherstrip.




The space between the hatch door and the walls varies anywhere from 1/16" to 7/16", so I pulled some 5/16" and 7/16" foam weatherstrip off the rack from Home Depot. In the photo above, there are thicker sections upper and lower, with the skinny stuff in the middle. It works pretty well, even if it's not super attractive.

Back to the doors and trim. I'm working with 3/4" angle aluminum to fabricate outside trim for the side doors. I'm using a propane torch to heath the material and gradually bend it along the outer curved section of the side doors.



In the above photo, you see one of the old doors serving as a mold for the aluminum bending. I used the old doors so that there wouldn't be any heat damage to the paint while softening the aluminum. I did the bending while the door was vertically oriented in the workbench in order to provide downward pressure more easily. Heat, bend a small section, screw it down and repeat. While doing this, I drilled 1/8" holes in the aluminum butting against the door edges.

I'm currently working on the second door trim. Both will require some final trimming once they are mounted on the new doors. This may require some heat, but just a little. I think. Touch and go.

I'm on to the week after vacation, so time will be shorter. But I'm getting close to finishing, like you finish any project. You just hit a deadline, which is still nebulous, so I'm just steadfastly chipping along. Here's a photo to leave this post with me and the shop cat, Tommy.

Teardrop Wiring: Raceway, Lights and Fan plus some Other Goodies

Spring 2018 started to show itself a bit a week or two ago. I decided to get into some wiring and also made my final decision on building a tongue box rather than buying one. The motivation was that I could customize the size to fit my needs. It'll be large enough to house the deep cycle battery and a full size propane tank. I'm not sure yet if I'll run a full size propane tank regularly, but perhaps for longer trips. 





Above, I'm cutting chunks of 3/4" plywood for the tongue box. The temperature was finally in the 50s again finally. Immediately the next day we had about 4 inches of show. Such is the new Spring here in Pennsylvania.





I've now mounted key elements of the wiring blocks in the raceway. Below, from left to right: busbar, ground-bar and fuse block.






The photo below is just a higher elevation view of the wiring raceway to provide a different angle. I have to break now to establish a milestone. Up to this point, the cabin lights and fan have been sitting quietly in place with the their wiring running through the ceiling and dangling into the raceway. I've finally terminated all that onto the fuse and ground blocks. The wiring from the tongue to the raceway is now also in place and connected.






With drums rolling, I set the battery on the tongue, popped in my fuses and flicked the switch on the main fuse...

We have power!


Ok, it's a minor accomplishment, but a good sanity check to ensure I didn't drive a screw through a wire somewhere up there. Below, I have two photos of all four cabin lights in all their glory.







I have the battery resting below with temporary connections, waiting until I have the tongue box built up. In the lower left of the photo you see the 20 amp fuse on the positive terminal side.





Below, I have a more focused view of the electrical raceway. On the left is the main busbar with the positive feed from the battery. The busbar breaks off at the top into the fan and two light feeds into the fuse block on the right. The middle block is the main ground. I'll post explicit wiring diagrams in a later post. I mean really explicit, NSFW (not safe for wiring more likely).




I've also tested the fan wiring, which you can see temporarily wired up in a few of the previous photos Final wiring for the fan will occur after painting and trim work. It was certainly a milestone to see the internal wiring operational.

I'll move on to the tongue box this week with a really nice battery mounting situation in mind, along with storage.
