DIY Hydraulic Shop Press

While taking a welding class I saw a homemade rig similar to this sitting in a corner of the shop. It seems to me like it would work well for simple pressing jobs, like pressing a steering stem into a triple, or bearings into a swingarm ect. If I'm wrong on it, if anyone can add any suggestions on improving design, or other possible uses, please post up.

One trick obviosly is that the jack would have to be centered, which could be done, possibly by welding, or bolting the jack to the lower plate. Since the top of those bottle jacks usually screw in, it might be better to weld that to the floater plate, that would allow the point of contact to be centered at all times.

Disclaimer: I havn't made one myself, but I have full intention of doing so. This is just a sketch based on something I observed.

Its not that tough I don't think. Just track down some scrap metal, or buy a few pieces from the metal shop. All that you really need is a welder and cutting touch to do the assembly. Maybe a drillpress if you want to make the lower plate adjustable. The more I think about it though, I think with the way the top of those jacks screw out, I think that would give you enough ajustment to do most pressing things. Then if you really need to adjust it far you could put a piece of 4x4" under the jack or something.

I'll have to talk to the teacher of this welding course, he might let me try a hand at building one if there is enough scrap around.

One correction I would add to the above plan drawings. I took a closer look last night, and it looks like the 3 plates, top, bottom, and floater, would be best made out of 1" steel plates rather than 1/2-3/4" After thinking about it, you get a good hydrolic jack in there and it would probly bend 1/2-3/4" plate. 1", it aint gunna bend.

and FYI the plates on this particular press were ~1'x1' though you could probably go bigger.
