This beautiful instrument was built from a teak cutting board that I got for free from Home Depot for review. 32" Eden neck, active electronics. Teak is hard enough for a simple oiled finish. This one was built with a minimum of tools, mostly by hand, to show that it can be done and how.
The Fret Slotting Jig is basically a very precise mitre box. What makes it a fret slotting tool is the Fret Guide, which attaches underneath the workpiece with double-sided tape, and engages a pin on the Fret Slotting Jig directly below the saw blade. The holes in the guide are spaced to Fender's formula, so depending on which hole you start with for the nut slot, you can cut anything from a 36" bass to a 20" ukelele, and all the standard scales in between. The guide fits snugly between the inner rails of the jig to keep the workpiece centered and straight.
