Basic Pressing Guidelines
Updated: Aug 20
Q. Will the caul bend a straight fret into the right radius?.
A. The caul wont bend the fret into the desired radius. The frets should be bent to the radius required before installation to avoid any spring back from the fret ends.
Q. Can the caul tip a fret over?.
A. If the caul and fret are not in line or if the caul is extended beyond its limit on the screw, the caul can potentially tip the fret over. For optimum performance and stability a maximum of 10mm-15mm caul travel from the highest position on the press screw is recommended. This will ensure that the caul is guided correctly in the forks.
Q. Should the fret caul be the full length of the fret?.
A. This is preferable as it will ensure uniform pressing over the fret crown for even seating and avoid potential damage. A full-length caul allows the pressure to be distributed evenly across the fret crown, resulting in consistent fret installation along the neck.
CHOICE OF CAUL
The selection of a caul is based on personal preference, but it's important to note that a plain, simple radiused caul can accommodate slight misalignment, whilst a grooved caul demands more accurate alignment.
