The template rests directly on top of the fretboard and is fastened in position along the sides of the base.

Slots in the fixing holes allow the template height to be adjusted for different board thicknesses.

When cutting the fret slots, the saw teeth pass through clearance notches at each side to avoid contact with the jig.

The specially designed saw, bottoms on the top of the jig, which sets the depth of the frets slot in the fretboard.

The fret slot locators should be fitted to the initial slots. This will ensure that positional relationship of the all remaining slots is maintained throughout cutting.

The jig is strong enough to be clamped in a bench vice which provides excellent stability for working.

Unless otherwise stated, the nominal jig base size is 715mm x 78mm wide.
