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 ($10 at a home center).
I used two sheets of 3/4-in. plywood to make the tabletops and aprons and ordered the folding legs from Rockler. My tables are very stable during use and they’re only 10-in. wide when clamped together.
