They wouldn't have to if the back and sides were skinned with even 1/4" plywood. The only problem with 2x2s is mounting the top rails in a position that screws aren't load bearing. A couple 3/8" SS carriage bolts per corner should suffice, but that would completely change the original design.


Hmm, RocketEngineer, how do the deflection properties of a spanning member relate to thickness? IE, 2x4 vs 1x4 or 1x6 etc? I think I read a factor of 3, but I'm not certain. The goal is produce a competently stable yet lightweight stand right?

The last stand I saw a friend build was 5 layers thick when looking at it from the bottom. It was so heavy I made sure I was out of town when time came to carry it upstairs where his new 4' 120g was going.
