I’m considering making the top of my new desk a torsion box. I think it will lend itself well to my plan for a modular design, and provide more stiffness than I’ll ever need. The desk surface is approximately 5’x2’, with probably a two inch filler. Just have a couple questions about using a torsion box:
1) If I use different materials on the top and bottom, will differing expansion rates cause trouble?
2) Is the expansion rate of the filler material important?
3) I’m planing on drilling holes into the box; does the inside need to be finished to avoid swelling?
4) What thickness would you run of hardwood plywood for the skin? The bookshelves supporting the top are all 3/4; can I move down to 1/2 for the top with a torsion box?
