Fret Press and Cauls | Guitar Fretting Tools | GMC Luthier Tools

"Your fret press works very nicely. Its a very well made and designed device indeed. I've re-fretted 2 guitars with Jescar Stainless, their most jumbo version - since it came on Saturday".

FRET PRESS FOR BOLT ON GUITAR NECKS - FEATURES:

Self contained guitar neck fret press system - Cauls Included.

High pressing force via screw thread.

1-2 turns will insert the fret under precise control.

Includes guitar neck support. 

9 Cauls - 60mm wide: 7.25", 9.5", 10", 12", 14", 16", 17", 20" & Flat.

Rubber edged base strips allow the press to be used on any surface.

Can be used free standing or permanently mounted onto a bench via fixing holes provided.

USING THE PRESS:

 

The fret should be pre-formed to the fingerboard radius. 

Locate the fret securely into the fingerboard slot and ensure that it is upright.

Locate the fret centrally underneath the fret press caul. 

Lightly tighten the press to grip the fret. 

Turn the handle to push the fret home (1-1/2 turns).

FRET SLOT & PREPARATION:

 

1) The fret should be pre-bent to the radius of the fingerboard.

2) When viewed from above, both fret and tang should be parallel and not twisted.

3) Ensure correct tang/slot fit. The fret tang should fit snugly into the fret slot up to the barbs by moderate thumb/finger pressure only.

 

With the above satisfied, the frets will be pushed perfectly home!

 

CAUL DESIGN

 

Q. "This tool makes the work seem absurdly simple! Do you think by adding a concave "V" shape to the caul ends it would help to ensure seating onto the frets?"

A. "For this system there would be no technical benefits. The design utilises simple kinematic location principles ensuring location and constraint of fret and caul during pressing. This greatly simplifies the fret/caul alignment without impacting the end result. The inclusion of a grooved caul from a comfort aspect is unnecessary and would probably cause the fret to tip over".

  • The fret is located axially (vertically and horizontally) in the slot.

  • The caul centralises (radially) on the fret crown under precise control of the screw.

  • The fret and caul are physically constrained.

  • Constant pressure via the screw ensures that this is maintained during pressing and the fret remains perpendicular.

 

The flat surface works perfectly and is far easier to clean. The cleaning is important for us as the glue we use sticks very well to metal!"

Stainless steel bridge with aluminium side pillars - 320mm distance in between.

High pressing force via screw thread.

1-2 turns will insert the fret.

Sturdy oak base with protective rubber seating face.

Rubber pads & cork mats for setting up.

Includes guitar neck support. 

9 Cauls - 75mm wide: 7.25", 9.5", 10", 12", 14", 16", 17", 20" & Flat.

Rubber base underside provides stability and allows the press to be used on any surface.

Can be used free standing or permanently mounted onto a bench via fixing holes provided.

Suitable for multiscale instruments also.

PRESS SET UP:

 

The bridge height can be easily adjusted to suit the clearance needed.

A rubber pad is placed on the fretboard to protect the instrument.

The bridge is lowered until the caul is at a suitable height for pressing.

The thumb screw on each pillar is hand tightened along with the adjacent allen screw to clamp the bridge in position.

The wrench is then used to tighten the stop plate screws (2 per side).

Set up of the bridge height will only be required when changing from the neck position to the overbody position.

 

USING THE PRESS: See Bolt On Guitar Neck Press description above.

FRET SLOT PREPARATION: See Bolt On Guitar Neck Press description above.

Please note, this press is not suitable for use with acoustic instruments. Please see our Universal Guitar Fret Press for fret pressing on acoustic guitars.

The press is suitable for use with multiscale instruments as there is sufficient space between the pillars for the guitar to be placed at the different angles needed for each fret. (The neck locator is not fixed in postion and will find its own position underneath the neck).

Please note that for multiscale instruments, the true radius of each fret will differ slightly from the nominal radius of the fretboard. This is only fractional but it will become 'flatter' as the fret angle increases. This is easily accommodated by using the next larger caul radius size as necessary.
