Ok i want to make my pro tools 105 bendor hydraulic with this bottle jack from harbor freight http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=36397. So if you can make any sense of my crude plans i wanted to know were the bottom of the bottle jack should pivot from so that its full strokes opens the bendor the whole way? Also if anyone has any better ideas for the "frame" should I make it a triangle the meets were the bendor arms pivot? Ive got plenty of 1/2x4 inch steel to use? thanks
