I’m seeing some variation in ceiling spar dimensions and species.
Being mindful of both weight and strength, I want to find the right balance.
I have maple and ash on hand, and given their strength (and ash’s moderate rot resistance. I’m inclined to use one of those.
Is 1.25”x1” too skinny? 1/8” ply glued in and out. 12” and 8 inch spacing, and I’ll mortise in a 2x2 hatch spar. Considering gluing in the foam as well, to add rigidity.
The roof is 5’ wide.
Thoughts? Am I going too skinny? It seems to me that for something that won’t get jumped on, this wouldn’t have any flex, with all the layers built up, but, of course, I’m a novice with campers.
Thanks, Nate
