This is a jig I built out of scrap wood laying around the shop to put a compound fingerboard radius on a guitar build I am working on. The radius’s are 10” at the nut and 12” at the 12th fret. The fingerboard is made out of ebony and the neck is mahogony.

I like the simplicity and I can see how you could adjust the ends to accomodate just about any radius you choose.

Very nice. I should use something like this to rough out the radii on all the builds I do. That’s one of my least favorite parts of a build.

I like the approach of using the jig over a router table instead of the other jigs I’ve seen which have a curved sled that the router rides on top. Did you make a sanding jigg with then American compound curve?

Have your say...
