JIG CONSTRUCTION

 

The jig base is made from hardwood (Ash).

 

This construction allows it to be firmly clamped in a bench vice without damage to the jig.

 

Threaded steel inserts are positioned along each side for attachment of the guides. The hole positions are standardised and allow interchangeability of different scales.

 

The base is waxed for protection.

 

There is a rubber grip covering on the top face for supporting the fretboard and rubber feet on the underside.

FRET SLOTTING JIG PACKAGE

Fret slotting jig packages can be supplied to your specific requirements. 

Please see the webstore for details.

Standard Fret Scale Templates

INCLUDED - FRET SCALE TEMPLATES

 

The Fret Scale Templates ensure the precise position and relationship of each fret slot. This is achieved with a few return strokes of the fretsaw at each position. As the photo below demonstrates the location position for each fret slot is at the exact surface plane of the fretboard whereby it ensures maximum positional accuracy.

Fret Slot Marking Out

The fret scale templates are lowered after marking the slot positions. (The photo below shows the templates removed but these can just be lowered using the slots).

An initial slot should be cut to depth at a central position along the fretboard. The datum slot locator is fitted to this slot.

CUTTING THE SLOTS TO DEPTH

 

The remaining slots can be cut to depth. 

The saw guides prevent accidental damage to the fretboard  from the saw.

Precision Fret Spacing Using Jig

"I love the slot locator as I can remove the fingerboard and place it accurately straight back in the jig". S.L., Bristol, UK.

NUT SLOT WIDTH

 

The jig can also be used to cut the nut slot sides. 

After cutting the fret slots, reposition the fingerboard so that the saw blade cuts the opposite side of the desired nut slot. (The board should be clamped in its temporary position). As shown below, the jig will ensure the slot sides are parallel.

The material can then be carefully removed by working from each side of the board towards the centre.

(The jig base - with the guides removed, provides an ideal set up on which to clamp the board and perform this).

INCLUDED - LUTHIERS FRETSAW

(The saw is also available for purchase separately from the webstore).

Luthiers Fretsaw With 0.023” Kerf and Depth Stop

The saw has a vintage (unused - as new) hardwood handle.

 

The saw blades are sourced from a single leading manufacturer. This ensures consistent kerf width and compatibility with the saw.

 

Spare Blades are available from the webstore.

Saw Features:

  • Precise control of saw cut depth.

  • Blade can be orientated for push or pull sawing.

  • Ideal for cutting nut slot sides.

  • Supplied with 5x 32TPI Hardened & Tempered Blades.

  • Useful in tight spaces where conventional saw access is restricted.

  • Kerf Width 0.6mm / 0.023”.

DEPTH OF SAW CUT

 

The maximum depth of cut is fixed and is determined by the bottom of the saw body which makes contact with the fretboard. The saw itself is no wider than a fret so any marking of the wood is minimal and hidden beneath the fret when fitted.

 

(The fret slotting jig is supplied with a 2.5mm depth fretsaw as standard. This can be substituted for an alternative depth if preferred). Please see web shop for details of saw depths available.

1-PIECE NECK ADAPTATION

 

An adaptation for 1-piece necks is available in both bass and guitar sizes.

The adaptor plates create the additional jig depth necessary for the neck and headstock. The headstock support height is adjustable.

There are two small packers which centralise the neck at the heel. Their position along the jig will be determined by the taper and width of the neck.

MULTISCALE JIG - BRIEF DESCRIPTION

 

The jig rests on top of the fretboard and is fixed in position using the fixing holes at each side of the jig base.

The saw blade is guided on the flat portion above the teeth. The cutting edge passes through a clearance slot at each side to avoid damage to the jig or blade.

To allow for the template thickness, the jig utilises a 4.0 mm saw in place of the standard 2.5mm.
