Silly me. I should have caught that because the units
wouldn't have come out in square inches, didn't do as
I was taught.... don't tell Mrs. Gilljie.

Correct on all accounts.

One thing bothers me though, on the one had we talk about hand
squeezing grapes or using a 3 pail system with one pail being
filled with 70 pds of water, but when it comes to a press nothing
less than a billion pounds per square inch will do? Seems on the
one hand the good enough will do but on the other it has to be
perfect??
