I bought this hammer at the swap meet for $5. It has two parts that clamp together with a nut on the handle side. The rawhide shouldbe between 2-1/2"-2-3/4" Dia. and I guess 2"+. Where can I buy them and what should be on each end? It looks like it says C/A cast on one end and 5 on the other ? I'm at a loss on where to look or what they are called. Feed store, dog bones, saddle shop, and how to do it. Boil it if I can find it , if so how do I roll it up hot. Leather on one side and rawhide on the other? It would be nice to have it in working order for machine stuff that you don't want to hurt.
