Building the walls

I used a flush cut laminate bit to solve the issue of having to trim the skin with only 1/4″ of room between the skin and the shoulder of the wall. A traditional flush trim bit would not work as the bearing was to wide to fit in the space. The tape was used to minimize tear out.

  • It’s probably right in front of me somewhere but what did you skin the inside of the walls with?

    • 5’x5′ 1/8″ baltic birch plywood.

    Hey Ryan,

    Just curious – you used epoxy on the edges of the walls where they come into contact with the metal frame. However later on for the interior of the trailer you used spar varnish. Any reason you can think of why the Minwax spar varnish wouldn’t work in place of the epoxy on the wall edges? I figure they are both means to solving the same problem of waterproofing the wood.

    • That should work fine but it is not a permanent water barrier for external uses and might need to be reapplied in the future. Since most water intrusion would occur on the edge that shouldn’t be an issue to reapply if needed. Take a look at Thompson’s Waterseal instead, it is meant for this purpose and might be a better solution.

      The reason I used epoxy was that I knew I would never have to think about it again, also I had it laying around and was eager to test it out 🙂
