I'm building some receiver hitch style mounts for my reloading presses. My new bench (one I built for our leather shop and we outgrew it) is 2'x4' with shelves up the back. The borders of it are 2x6 lumber. I'll cut a square hole in a few locations to be determined and bolt my home made receiver hitches to the bench. Then I'll weld a plate to the smaller square tubing that the press will bolt to. Then I can move presses around with the turn of a bolt that I'll weld a t-handle on. A buddy of mine is who I stole the idea off of. He's got 7 presses and various other tools such as a swager. No more space than he has he can't have em all stationary. I'm kinda in the same boat.
