which frame/hand pump do you use?

Supposedly you can get up to 160lbs of pressure out of it, but I sure wouldn't want to have to try.

I saw that, too.

The seals may very well be good for that much. My upper body strength, OTOH - don't know if my physics is correct or not, but I think with a bore of roughly half a square inch in area, that means you'd have to generate over 300 pounds of force between your hands.

I might be able to leg press that much (1RM). Between my hands, uh, not.
