Most of my sheet metal, if not in full sheet, is cut to two foot widths to be able to stack in this stand, made from leftover pipe from the air line install. Pay no attention to the cable stretcher.
For cutoffs, I was using the space below the weld table to just lay the pieces on the floor. Down side to this is that it becomes hard to see what is at the bottom of the pile, and because you can't readily sweep up anymore, becomes a mess. So during our last spring cleaning, with the cutoffs out of the way, I couldn't bring myself to fill up this floor area again...
So we made use of wasted space by adding some square tubing underneath the welding table's top for support, and used our "radius brake" to make the bends in a piece of diamond plate to form the shelf.
Both have helped to keep things more organized in the shop, and now the floor stays cleaner under the welding table..
