OK, so it only took me two weeks longer than I thought it would to get the project to this stage. But we're here at last..
I've built a little hydraulic press for home.
Of note, I used one of these little units for the muscle:

So I have all the heavy bits fabricated and working. Now I'm moving to the controls. What I want is a lever control for raise and lower.
The lever bit is easy, I have a 5/3 way lever valve.
The press bit is easy, just use said valve to supply air to the motor (might have to be via a pilot operated valve, this thing uses a bit of air).
It's the release bit that has me scratching my head. I could use a rotary actuator. But the mounting brackets would be a bit of a pain in the arse because the little drain valve is at an angle .I'd prefer to use a ram and control horn, but the same applies. I'd really rather not strip the thing and add a separate valve...
Anyone got any suggestions?
