Two bearing wheels added on the side parts that sit and slide on the top of the radiused spares, which also suffered some changes.
The pin on the side parts used to go all the way through the radiused spares rip and cause some friction, so the pin is now smaller and the rip disappeared leaving only the required space to keep everything on track and smooth.
Jig with compensation radius, that allows a 80mm wide fretboard (as V2 and V3).
Easy way to make your radius on fretboards. This aluminium/acrylic jig will slide easily through the wood jig (not included) and will shape your fretboards almost to perfection (you still need to sand a little with a radius block after this operation).
This jig include a set of radius jig at your choice (choose under "Available Options") your desired radius to be delivered with original Fretboard Radius Jig.
Additional radius jigs can be purchased separately. Available radius for V4: 7.25", 9.5", 10", 12", 14", 16" and 20".
