To save bench space on my workbench I made a receiver hitch for the workbench in my shop. As I have built, I have added these to my welding table, and shop press. These also fit in a truck receiver hitch so I can go mobile with all my bench top tools. I weld a nut on them and use a bolt to make them tight so they don't wobble around. I also have made most a little long so I can use them in the truck with the tailgate down.
