Pounds are used to measure force, not pressure. There is an important
difference.


Indeed. A clamp which can deliver a force of 250 lbs can give a force of
thousands of pounds per square inch if the contact area is very small, or
almost no pressure at all if the contact area is large.

Easily demonstrated by placing your hand on the floor and asking your
lovely wife to step on it quite slowly. First barefooted and then while
wearing her high heels.

There's more than one reason you don't see a lot of vinyl tile in
business places. High heels will dimple it better than a ball peen hammer.

You'll be back at that lathe or table saw in four or five weeks!
