I'll HAVE to build one,....any pile of rubble vaguely resembling an original Trip Hammer seems to be worth an arm and a leg.

Been thinking about an Air Jack, as well,.....but at some point, the cost break over makes the all Electric rig appealing.

In terms of longevity, and sheer durability, those 140 year old designs probably still RULE.
