Fretboard Radius Jig

I made this jig to fit parts I already had on hand. I will include the links to the parts you would need to complete your own version or feel free to modify it as necessary.
The router base was designed to fit a Porter Cable 6430 Trim Router. You will need to print two bearing / frame clamps and also two radius blocks. I attached them to the frame with double sided tape. the fretboard radius can be changed by altering the radius of these blocks.

These bearings are not as long as the ones I used , but should work the same way. You can modify the bearing/frame clamp to fit them
I used 1/4 -20 hardware for the clamps and the bearings.
