Check out the historic garnish bolts Jymm Hoffman is forging with Say-Mak hammers.
Currently there are about 300 Say-Mak air hammers in use in the United States. We are providing technical support for these machines and carry an assortment of spare parts. What we don't have in stock we can order from the manufacturer.
We just finished rewriting the manual. If your older hammer is an undocumented immigrant we can get you the papers! Just ask and we send you the pdf which explains its inner workings, features, and maintenance.
