Home built press

I figure OFN was the place to get some feedback. I just saw another thread on a press build and it gave me the idea to build a break for it. I picked up all the steel for free at my previous employer so all I have in it is my time, some wire and gas, and a $75 air operated 20ton jack. The design was pulled from a press at my my p.e.'s shop but I have some what over built this one compared to the model.

Looks like he removed the springs from the RAM and used them to not only pull the shaft back in but the entire ram up... doubles as both.

No, it looks that way in the last pic though huh. It is double 3/8" plate with a 2x2" square stiffener centered above it. I don't think that's where it's gonna bend.

ToddW got it, they came with the bottle jack attached to a little plate. I just moved them out to pull everything back up.
I just welded a 1/2" nut on top and an adjustible eye-bolt on bottom.

Care to share material specs & dimensions? I've always wanted to do up a set of plans for one of these to share with people, but never got around to building my own.

Feel free to PM me if you'd like.

Before anyone duplicates it have him bend a bunch of shit and do some thick dimple dies and see if its still straight. No sense in copying something that has not been thoroughly tested. I only say this because my HF press (yes I know weaker) bent at the top, and table VERY VERY easily, and I think your table could see flex on dimple dies where the stress is concentrated . Not knocking your design but thoroughly test, then re-inforce and go go go

Yup, it's usually right in front of your face. Thanks for the heads up.

Your right. I haven't really put it "to the test" yet as far as a butt load of pressure but it is coppied from a commercial press I used to work with and mine is over built compared to it. I wish I could afford a good set of dimple dies right now but it aint happening.

The c-channel is 6"x 1/4" on the flat. The Uprights are 6"x4" I beams. and the plate up top is double 3x8" (I was going to use 3/4" but it's a little hard to find that big. I've placed a 2"x2"x1/4" gusset directly above the jack head and fully welded it. The press point is a 2"x2"x1/4" on end with a 3/4" plate on the end of it. The guides are just a 1 1/2" sch40 over a 1" sch40. I can get measurements later for you.

So far I have pressed ball joints, axle studs which neither require a lot of force. So I sacrificed a piece of 3/8" plate and bent it with a piece of angle under the ram and it bent it like butter. I had to stop because the plate wasn't wide enough to stay on the bottom plate much past 45*. Every thing held together nicely.
