Appreciate your input but I'll be building it regardless.

Lets see how it goes

No more help for you.

On the 100 ton at work we had bent two inch press plates .When you are near press capacity and it lets go ,be ready to change your under ware . Do not stand to the path of the explosion .

Start with a 100 ton cylinder and test to failure. Once the first iteration fails, clean your shorts and modify and test again. Lather, rinse, repeat.

Show us some pics of other projects have you completed if you have any.

I don't meet your qualifications to move forward with the project. Ok. Am I supposed to let that stop me? I'm a grown man and I make my own decisions at my own peril. Don't expect to make executive decisions on my project.. the most you can do is offer advice (and I appreciate you attempting to help).

Woah that's crazy powerful. Must have been scary as hell

My press won't ever be used to max capacity. I don't have any work that would require me to put out that kind of pressing force. The max capacity is "100 tons" but I have no intentions of ever maxing it out.

If I bent plates it will be 1/4" or less. Realistically I'll probably just compress steel billets and press sheet metal into forms or something. Nothing crazy.

Test to failure? I don't follow? What's the purpose or forcing a failure?

I attached some pics of my previous engineering feats. That's me installing the AC unit.

Many times you would be at capacity with nothing moving and some joker would go get a porta power .That was my time to have to go take a crap .

I have a 100 ton Enerpac, and I don't know where the 2" plate comes in.
As a non-engineer, I tend to copy the engineering done by a company making good stuff.
For instance, my uprights are 4" X 3/4" angle iron. The work apron and the top crossbar are 12" channel that is 1/2" if I recall. Top bolted on with 6 - 1.5" bolts.

With the pump I have, I generate 40 tons, and have never yet had something in the press that would not move or bend as required.
If I ever need to go full tilt boogie, I do have a more powerful pump, but the safety factor gets narrow at that pressure.

Wow, a water-cooled 20 Amp outlet! I bet that could handle 30 Amps continuous, at least.

Wasn't there a member here who documented a 150 ton press build for his Dad some years ago? Maybe a different forum ...
