Guitar Binding Jig Donut

This is a common piece among the various styles of binding jigs available on the market. If you're looking to make your own jig, chances are you will be buying or fabricating one of these donuts. This first version is designed for a 1/2" straight or spiral bit - I can also make different sizes if there's interest.

Update 1: Added a version with a 1.75" ID at the request of a member.
