Ok, this is a shoot off from Russ's (Torker) press build. I didnt wanna distract from his nice press. Good job Russ!!!

I just wanted to show some pictures of mine and maybe give some ideas to others of
some possibilities. The good part is Ill tell you what doesn't work so well and you can bypass my mistakes. Learn from my mistakes and you could write a fat book, I have many LOL

So here are some pics.. The thing was made in the ninties so steel was less expensive, oh, but my pay check was alot less too so its a wash..

Oh, and I didnt know anything about structural integrity or how to weld and still dont so it is what it is,,

I built it for the need to squish stuff, and not at a fast rate, but affordably.. I have used it many times. I made certain "dies" if you wanna call them that. More like pieces of steel fitted together to accomplish a task.. Here it is..

Umm, ok, this is a full shot of it..

It looks very substantial.Very nice job!

I was wondering why there are two pumps on the ram?

That's OK, the spring clamps should hold it together.:cool:

Ok, pics are up.. Now, for the use of the thing. Again, I dont know scrap about designing stuff or how things should be built. Just needed a press so I built one.

The sides are H-channel, 4x4x 1/2" web.. The top is 3x6x 1/2 C-channel as is the bottom base. Again, I dont know steel nomenclature, these are just measurements I took off it right now. It may be called something different in the industry. Just as a two by four isnt really two by four inches..

I welded some 1/2" plates as gussets all along the inside of the top and bottom channels to strengthen it up.

The jack sits on a 4x4 x 3/8" I-beam. It doest see much force, it acts as a guide for the whole up and down process. I say doesnt see much force because it does see some side loads. The ram wants to push straight down but sometimes I dont have the work centered correctly and it wants to put a side ways load on it. I have bent the "fingers" up somewhat with this. Pic available if needed..

And its on rollers so I can scoot it around the shop..

I love this press, never let me down yet..

Oh, its scary at some times.. The jack is a two speed jack. Pump it up with one handle (or both for faster action) and it clamps down tight on the work piece.. Put the handle in and start cranking on the high pressure handle and things start getting tight!!!! Real tight.. I have the top Channel gusseted pretty well with alot of 1/2 plate and she still wants to bow, I can see it at the top..

For my back yard machinist gage I will put a straight edge level along the top beam and go to crankin. It is flush at the beginning, then if Im putting a strain on it I can see about 3/8" air on each side. Thats when I know Im putting the pressure to it. Rudimentary??? Oh hell yeah!!! Thats how I work.. How do I know 3/8ths is good enough?? LOL, Dont ask.

All I know the let loose point wasnt the press frame. More like the other parts!! Always were eye protection, things are under a tremendous amount of pressure and its like a spring, most dangerous stuff in the shop, spring actions..

Not that the fancy poly eye wear isnt gonna protect you from the flying 1/2" steel slug popping through yer head but at least yer casket photo will still have some perrty eyes in it JR

LOL Yeah.. It strated with any horizontal surface is fair game for storage.. Then I found a whole new world!!! The vertical surfaces are just as useful.. LOL

You dont even want me to take some pics of the shop. Head to toe, PACKED.. Funny part is, for the pictures I actually took off ALL the junk that was piled on it.. Guess I forgot those, I had already stripped her down and thought she was naked!!! LOL JR

Built one similar to this only use a 20 ton jack.
The main fault I have found is having a fixed length ram, always seems to be
to long or to short,intend to alter it to take different size rams, also hope to set up a device to make altering the bench height easier.

Hi, thanks. Its a two speed jack. The one pump on the left is faster but not as powerful, prolly a larger diameter bore. The other is full power, smaller bore, more pressure. And you can use both at the same time to bring the ram out quicker.. JR

Yeah, I agree. The stroke is about eight or ten inches, good enough for each job. And the bench or table is heavy on mine. I just lift one side at a time, pull the two one inch pins and put them in the new holes then do the same for the other side.. JR

Are there springs on the outside of the beam to pull everthing back up?

When i use my homemade press with a setup i do not trust i clamp a piece of plywood against the frame at the point the workpiece will most likely fly out.
It has already saved me:o

JR..Thanks for the pics! Geez...the ideas never stop coming around here.
I like how you put the springs (?) (Don't see any) well cables on the outside. That would have been easy on mine and would have cleaned up the inside of the press.
When I build my 50 tonner I'm going to have to build swinging doors made with heavy expanded metal to stop things from flying out of the press during use.
Workers Comp requires it and it's just plain good sense.
In your case you'd have to make a slot in the door for the handles to stick out but it's still doable.
That's crazy how much power these things make huh?

Your pin hole positions look to be drilled a little bit cock-eyed. If they both are not dead nuts even, only one pin will take the load. Perhaps it is just the camera lens. If they are off a little, perhaps a fix could be to use a die grinder and grind the bottom of the higher hole so both bottoms of the holes are even. Does that sound right? Nice press though. I have a 25 ton KR wilson and pressing to 25 ton is a little scary, so I know what you mean.

Thar be springs in there.. One on each side. I like the safety door idea.. I really should do something. It does scare the crap outta me. Yup, crazy FUN power.. I just like to squish crap.. JR

Yeah, good eye.. I did the best I could at the time. Just had a lil tiny drill press and a greenlee hole saw. The pins can be rotated by hand, one on each side. There is maybe a 32nd of an inch space.. But after that first pump of the handle everything tightens up real quick. Cant move the pin after the first pump.. JR

Ahh...the good ol' days! I remember that. Torch, grinder, files and a small drill press. That was it.
