Efficient storage is important in my garage shop, so after use, my assembly tables tip, fold, clamp and roll. Each table has one apron-mounted caster ($7 at a home center) and a stabilizer. I used two sheets of 3/4-in. plywood to make the tabletops and aprons and mail-ordered the folding legs. My tables are very stable and only 10-in. wide when clamped together.
