Be not annoyed, oh mighty mods, I post here hoping for more suggestions on Presscilla...

[MERLIncMan]

It is a ~30 ton general purpose hydraulic forge press thing, I posted in Hydraulics asking for suggestions, but it also fits here.

Before I call it complete, I am hoping for some suggestions from my fellow chip-makers.

Here is the other Post: https://www.hobby-machinist.com/threads/presscilla-im-interested-in-suggestions.102506/

Can’t help…just jumping in to say that it looks amazing. Can’t wait to see it in action.

First, That's a very nice looking build! Yes, please show a video of it being running and tested. Then it's complete.

I've got to get the hydro-hose and oil, then install the breaker to run it, but I'll be certain to get you a video of the first squish

Thanks for the look!

I built a press a while ago and use air pressure on the return to raise the cylinder back up
It has to have back to back seals so the air doesnt bypass into the hydraulics

Nigel, you're saying that you put shop-air into the other side of the piston, and that it required a doubled up seal?

If you have a double acting cylinder it should be okay
Mine needed a little modification as it was only single acting
It only takes about 50 or 60 lbs of air to return it
The regulator bleeds of the air as the cylinder extends so no valving was required

Ok, no extra seals needed, but I would have to plumb shop air to it, or just pump it up with a Schrader valve once?

I plumbed shop air to it
not a big deal for me had air closeby
never tried pumping it up once didnt want the air pressure to increase with the stroke of the cylinder
the regulator i use ibleeds off the air so it doesnt rise more than 10 to 20 lbs above set pressure
your cylinder looked like it had a port for return was it bought as a retractable type?
