After thinking a while on what would be an ideal table for my needs, I finally got started. Top is 4'x 7' x 1/2" plate, flattened. The slots will allow me to get a clamp on 85-90% of the table.4" x 5# C- channel will form the perimeter and cross supportsThe 3" square cut-outs are for the middle legs and will act as a receiver for my grinder, vise, and bender. Outer legs are 5 x 5 x 3/8"which I found in the scrap section of the steelyard. Too good of a deal to pass up. Brackets on legs are for the wheels. There will also be levelling feet at each leg. Should have it buttoned up this weekend. I am building it upside down and will flip it with either a chain hoist or forklift.
