Design News and Allied Electronics would like to send you a check for 70122993 Cap Ceramic Mono .01uF 50V 10% 1 that it was guesswork when using a hydraulic press to straighten a piece of material.You apply the force and then you gradually increase the force with each successive try. You usually track the appropriate force by counting the number of pulls on the pump handle. Not very scientific. So Ed created a gadget that indicates the actual force that is applied. The goal was to make the process of using the hydraulic press both quicker and more accurate.
