Building the sides
Time to construct the sidewall framing. I put together the aluminum siding so that I could use it as a template. When I compared both sides of the assembled aluminum siding, I noticed that the sides didn’t match. Since I wanted to make two identical frames (the perimeter), I knew I would need to fudge the aluminum siding on one side to fit the frame when that time came. Drivers side This is the inside of the passenger side skinned with 1/8” birch. I used a polyuerathane construction adhesive to glue the birch plywood to the frame. I used bricks as weights to keep pressure on the frame against the birch until the adhesive dried. Passenger side frame. I used exterior type 3 wood glue and pocket hole screws for the joints. The frames are made of 3/4” marine grade plywood. I copied the original frames for the most part. I did add some bonus pieces in select areas for strength or where a hole might be drilled or a fixture attached.
