Review on Enhanced Safety and Grip: Antislip Holding Capacity Horizontal Release Industrial Power & Hand Tools by Trevor French

I have used 2 larger clamps as retractable swivel wheels for my welding table. I welded a nut to the end of the yoke and screwed in the swivel wheel, then I welded the yoke to the leg and bracket. Boom! retractable swivel wheels! When standing, the welding table rests securely on the stable table leg with leveling screw.
