Re: Roof Spar Joint - Alternatives to Butt Joint

That's an interesting idea ... framing the roof independently of the sidewalls.
So far, it seems the best solution for a solid plywood wall would be to route either a mortise pocket or an entire rabbet into the interior lip of the wall. That gives the spar something to a) rest on and b) prevent it from twisting. Using two screws per end, rather than one, would also add strength.
I understand the apparent appeal of sandwich wall construction, but again, I promised not to high-jack my own thread, so I'll skip that :p
I also like the idea of stapling the aluminum siding to the framing before attaching the aluminum trim. Sounds like a good fail safe in case the screws in the aluminum trim ever weakened and pulled out.
