Hi James, Steve is right...

Response to Hi Wyo, Do you have a way to gauge the pressure,

The pressure is indicated by setting the piston length to make contact with the valve. In this gun, it was when the forearm is 21 mm from closing. You stop pumping when the piston doesn't contact the valve.

The force on the piston, and the resulting strain, are directly proportional to the accumulated valve pressure. It works pretty well. I got the idea from Steve's "tell-tale" indicator. It's kind of spin-off, thanks
