It will need new hammers, but I'm thinking I'll need to bore the hammers myself if I am to get the same angles--I'd like to keep it true to original if possible. Is there is a jig available that will serve this purpose? Arlie Rauch -------------- next part -------------- An HTML attachment was scrubbed...
