Why I Built It
After radiusing countless fretboards by hand, I wanted a system that was faster, more repeatable, and compatible with the compact routers many builders already own.
Every version of this jig has been refined through real use in my own shop before being offered to other builders.
Unlike generic woodworking jigs, this system was designed from the ground up for guitar building.
