JM Performance Products

JM Performance Products, Inc. was established in 1966 in Euclid, Ohio by owner John Stoneback in the basement of his grandparent’s home. It wasn’t long before the job shop, which focused on precision defense parts, out-grew the basement and had to locate to new facilities. Operating as J&M Machine, Inc., the company quickly gained the reputation of being a stereotypical job shop, dedicated to being a model shop leader for manufacturing development and quality control of precision turned parts.
