This articulated mount arrived today which I found on ebay. It was listed as a " Hydra Clamp ". Its cast iron and well made. I have a couple of small vises on similar bases and thought this could be modified for welding purposes. Turning in the screw hydraulically forces a piston up against the rotating ball to hold it in position. I drilled holes in a 2 1/2" C- clamp and attached it to the threaded arm. Overall, it should be a handy shop item.
