I'm building a truss dob, 18" f4.5
Kriege and Berry recommend 5/8" thick wood for the mirror box, but I seem to only be able to find 1/2" or 3/4" for Finnish Birch that I plan to use. So the question is... would 1/2" be a problem? I tend to over build things so my inclination is to go with 3/4" but since I know that I tend to over build things I thought I would ask the question.
So do any of you use 1/2" plywood on an 18" scope?
