I have been doing a lot of thinking about incorporating torsion boxes into CNC machines.
I love Baltic Birch ply, but the cost starts to add up. Any thoughts about using MDF as the inside matrix with a 1/4” Baltic Birch skin? Does the humidity problems with MDF need to be considered with the more stable ply skin? I am afraid the MDF will want to move, and the ply won’t let it. I believe that MDF only grows in “thickness” and if I cut my struts (matrix) “on edge” that I will be OK. Is this true?
