Re: Pneumatics...

Yes, you're quite correct. Only 18.5 cu in of air are available at 60 psi from one of the Clippards at 120psi. Unless you use the vampiric, suck 'em dry, mechanism...
I also see that there are several unfinished notes that should be fleshed out. Senioritis obviously set in - both mine and my students.
Thanks.

While this would be true if you could evacuate all the air from the accumulator and send it into the cylinder, in actuality can't you only run a 2"x6" cylinder once at the full 60PSI? After running this cylinder once the volume of air in the accumulator would be cut in half so the pressure should be cut in half as well, right?
P.S. Ed, I'll have to check on those.
