In looking around for the best buys on the tools I actually have to buy versus make to repair bowed string insytruments, I encountered a tool that I haven’t missed having—yet. Seeing that it’s looks like a counter sink bit on a handle, I made one.

The handle is a turned spindle that I saved from a piece of furniture for just such a use. I just had to shorten it and drill a hole in one end to accept the counter sink bit on one end. I glued it in with epoxy and gave the wood a good coat of boiled linseed oil. I do plan on making stringed instruments, so this will get some use. It’s purpose is to very slightly chamfer the outer edge of tuning peg holes so that there’s no flash to interfere with the peg.

Below you can see a commercial model demonstrating its use.

Thanks. I figure I’ll get some use out of it eventually.
