The old drafting board I carried around for first year engineering was built sometime like it with a balsa core. Now I'm sorry I got rid of it. I could use it now. I need something I can just put away and use from time to time. I have a nice work bench in the garage, but it's 32 degrees in there right now (and it's 18 degrees above normal presently). Basement is getting to comfortable for the kids and wife's sewing room/ computer room.
