APEXISH work table upgrade #1

I wanted to add casters to my welding work table as well as a shelf to store tools. I had boring 4" square tubing legs tacked on temporary and I didn't want to have something that simple... I got these beam cutoffs from my shopmates overhead crane project. So first off I cut a stencil "A" out of thin scrap 20gauge and transferred that to the beams to cut. Using I beams like this ensures both sides are the exact same height, no matter what. The table top height is 34" and it rolls way too good... next upgrade will include floor brakes.
