JIG OVERVIEW
A range of pre-designed multiscale fret slotting jigs for 6, 7, 8 string guitars & 4-string bass guitars. The supply includes a layout gauge to assist nut and bridge angle positioning. The layout gauge also features the geometry and relationships of the bass and treble scales to each other and reference to the centre line of the instrument. The jig is strong enough to be clamped in a bench vice for easier working.
The supply includes:
- Multiscale Fretboard Slotting Template.
- Multiscale Slotting Jig Base.
- 2x Fret Slot Locators.
- Fretsaw (for depth see below).
- 5x Fretsaw Blades.
- Multiscale Layout Gauge.
JIG SET UP & USE
The jig base has a ribbed top to help restrict movement of the fretboard.
The fretboard blank width should be trimmed for a snug fit inside the jig base side plates.
The multiscale fretboard template rests directly on top of the fretboard and is fastened in position via screws along the sides of the jig base.
The saw blade is guided in the template slots and the teeth pass through notches at the corners of the template. (See Photo 1).
A fret slot locator should be inserted after cutting the initial slot. It is recommended to use both slot locators and position these at opposite ends of the fretboard.
MULTISCALE FRETSAW
Fret slot depth is achieved when the fretsaw spine contacts the top surface of the template. The fretsaw supplied – 4.5mm depth – includes an allowance for the template thickness. 5 blades are included with the saw. Spare Blades can also be purchased from the web store.
MULTISCALE LAYOUT GAUGE
The Multiscale Layout Gauge is an invaluable reference tool for the instrument build. The gauge ensures correct positioning of the nut, bridge and geometric relationships of the scales with reference to the centre line of the instrument as follows:
Nut Angle
Bridge Angle
Treble Scale Length
Bass Scale Length
Nut String Spacing (Overall)
Bridge String Spacing (Overall)
JIG BASE DIMENSIONS
The multiscale jig base is 715mm long and will accommodate 78mm maximum fretboard width. The fixing screw positions are common permitting our standard bass and guitar scale templates to be fitted also. If purchasing standard templates for use with the jig, it is recommended to also purchase a 2.5mm depth fretsaw.
