For sale: a blacksmithing power hammer. built from scratch. Has about a 40lb hammer but the pneumatic cylinder and accompanying pneumatics should be able to support 100 lb hammer easy with some minor modifications to the hammer weight and the guides . works well. its solid and works well. with a little research an few cheap parts you might be able to take this machine to the next level. this is the Only power hammer ive ever used so i dont have a comparison. I enjoy using it. the hammer drastically improved my productivity making stone chisels but do to a move I will be switching to a hydraulic press to keep the noise down.
