If you find a good solution, please let me know. I bring a tractor PTO
compressor out to the field every day. I could reduce the tractor RPM
(save fuel) if such an accumulator could be designed.

I've thought of adding a couple old 100 lb. LP bottles but don't want
to wait for the whole system to build pressure before starting. The
shears need 100 psi to work so you can't start until almost to cutout
pressure.

Karl, I am still thinking. Yesterday I thought to go with what Lloyd
recommended, a flow control valve. Then I realized that it is not as
good as I want. There is an energy loss and also the system will not
come up to pressure fast.

Nw I am leaning towards a system with a check valve for air outflow,
and a pressure switch controlled solenoid valve for filling.
