    Pressure test

    Anyone have a hydraulic shop press with a gauge? place sample on 2 blocks and push down on the center.

    Use a dial gauge to measure deflection and read the PSI on the gauge.

    Think I saw it on Mythbusters

    Basically a hand pump connected to a hydraulic cylinder with a pressure gauge in between.

    That will tell you what PSI the jacks pushing down with, from there the smarter people in this thread could work out the calcs
