re: Making a form for an arch

Thanks Paul, all clear.

What about the spacer between the 2 ply? it looks like it would have to be 2" thick. I can manage that. How deep would it have to be?
I realize that the laminates will be supported by the 2 ply as well but I am concern that it could give in under clumping pressure and that will translate to the laminates.
