Adjustable Fret Press

Posted by on Mar 11, 2012 in Articles & Tutorials, Instructions and FAQs, Prototyping

Most EGS guitar orders are for stainless frets, which, if you’ve ever worked with them, take a lot of effort to work with. Accurate seating of the frets makes for less leveling work, which in turns leads to less re-crowning work and saves lots of time. I have always hammered my frets in, which doesn’t always meet the above criteria, so I wanted to try pressing in the frets. Conventional presses (read Stewart-MacDonald) come with brass inserts for set radii. But with a compound radius fingerboard, or a multiscale fingerboard, there is a lot of variation of the radii across the fretboard. Additionally, the StewMac inserts are only 63.5 mm (2 1/2″) with isn’t enough for even a 7-string multiscale fingerboard. After a lot of experimenting, I have come up with a preferred compound radius formula starting with 16″ at the zero fret and reaching 20″ at the 24th fret. For a 25.75″-25″ scale on a 7-string with a neutral 4th fret, the following picture shows the radius that each fret describes: As you can see, the increase in radius between each fret is not linear, but less at the first frets and the last frets, due to the angles of the frets. The idea of making the press...
