Here is a hand built , plug and play cp hammer. I build each one from scratch and source out the vintage cast iron bases. The motors are Michigan pnuematic units that I modify to perform their best. This particular unit is newly built and runs flawlessly. Uses CP upper dies and Cp/tm tech lower dies . These are incredibly useful hammers for smoothing tig welds, straightening early ford flanges without stretching, making sail panels, and lots of light sheet metal forming . Unit comes with one lower die and one upper die. May part trade for early ford parts.
