In the press I had in mind the pins would be holding the load, however.
The idea is that the press looks just like an H or a C press with square
tubing instead of C channel. Obviously not as heavy duty, but that's the
tradeoff of versatility. In a hoist configuration would be like an "A"
frame hoist but two verticals and a broad tubing base. Beats unfolding the
engine hoist just to move and engine on or off the stand. As a table or
work surface you could use four legs or mount it to your hitch. The surface
could be wood or metal, and would just have 2 1/2" square tubing pieces
lying flat on the corners so that the other pieces could connect in whatever
configuration works for the situation. My small drill press, vise,.
grinder, and maybe a small anvil would all be mounted on their own plates
with receiver sized tubing on the bottom, set up so that they can be
attached to your hitch (maybe even more than one at a time, if you use the
right combination of pipes, tees and ells) in whatever arrangement works, or
moved to the workbench where I hope to have more than one receiver mounted.
I'll have to mount the receivers actually independent of the work bench, to
the wall and maybe the floor, because every time I bang on my vise the whole
work bench (2x4's stoutly arranged, with countertop) rattles my mess about
I say hitch because folks get the idea of how it connects, but if you're
thinking something, I'd really like to find out what you had in mind.
Taking the load off of the pins is always a good thing.
I also figure that it's a lot cheaper to jaw an idea over before
spending money with the high price of steel, and less waste from getting a
bunch of opinions instead of stuff I didn't think of.
