A piston less than 1/4" across has an area of 1/2 a square inch, so
20psi oil pressure gets you ten pounds of force,

No, that would be 5/100 sq" (.049) for a 1/4" dia. piston (extend, only.
The rod would reduce the retract area and force.)

So, for a 1/4" piston, you get just under ONE pound for 20psi.

Ah, crap, I was thinking radius and using diameter. Or the other way
around. Sorry, Valentine's Day ****s me all up.
