I am planing to build a torsion box to use as a base for my Jet contractors saw. The base will be approximately 2' X 4' and have 4” locking casters at the corners. I will be placing a cabinet with some provision for dust collection and drawers for storage between the base and the saw.
My question is if I am using 3/4” MDF or ply for the torsion box and cabinet construction how thick do I need to make the inner torsion box members? Is 3” necessary or would 2” or even 1.5” be enough for what I am planing? I assume that at some point the inner members become too thin to be of any significant structural value.
Thanks for any input,
Craig
