Here's a link to some pictures of some of my shop tools. The Hossfeld was converted to hydraulics. The bender uses the two DA cylinders as SA cylinders, when one is pulling, the opposite one is returning. We had a tornado come through and I needed a dump truck so I robbed the hydrailc pump off the unit to use on the truck I built a dump body for. It was 12vdc electric over Hydraulic with power both ways. I now have a 120VAC APU I'm going to install back on it with a standard hydrailc control valve with a lever action. I'll have about 1/3 of the $$$ I had when I did it with the 12vdc system, most of it is salvaged stuff.
