Used this “wall hanging” yesterday. My hydraulic press hangs on two farm gate hinges, screwed deep into the posts that hold up the rest of the barn. The female hinge portion is welded to the press frame. It swings out for use and then stores tight up against the wall the rest of the time, up off the floor, out of the way.
It’s a small unit, that was in the way, sitting on the floor. We had to sit on the floor to use it. Hanging up a few feet off the ground makes a huge difference. One of the “L” brackets is drilled for a safety pin so it can’t jump up and off the mounts. Not really shop art, but everyone that sees it stares at it for a while and then builds their own copy! On Sale a few years ago for $99, one of the best tools I’ve bought. Should have done it 40 years ago!
