Thanks for the formulas Glenn.

I ran the numbers to get some idea of what I might be looking for.

Seems I should be using about a 2"X20"X1.5" cylinder, 318psi @ .186gpm.

Using a slightly oversize pump at a lower RPM, I would need a 1/4hp motor to
achieve the 15 sec. hard over time.

Seems do-able on paper. I just don't know what the max current draw might be
for this motor. I'm sure someone has a formula for this as well.
