This section covers adding new frets or [https://Fretlets.com fretlets] (short frets that don't reach all the strings) to an already completed Kite guitar. The fret you are adding may or may not have a tang, and you may or may not need to cut a fret slot for it. | This section covers adding new frets or [https://Fretlets.com fretlets] (short frets that don't reach all the strings) to an already completed Kite guitar. The fret you are adding may or may not have a tang, and you may or may not need to cut a fret slot for it. A tangless frets is secured with glue or two-sided tape. You can place it temporarily with ordinary tape over the top of each, and check the cents with a tuner. Or you can use the following formulas. | ||
To add <u>tangless</u> frets, measure X and F like so: | To add <u>tangless</u> frets, measure X and F like so: | ||

The new fret will not be exactly equidistant from the neighboring frets. It will be slightly closer to the higher one. The formulas are: | |||
* D1 = (X + F) / (1/K + 1) - F/2 (edge-to-edge distance from the lower fret to the new fret) | |||
* D2 = (X + F) / (K + 1) - F/2 (edge-to-edge distance from the new fret to the higher fret) | |||
* K = 41st root of 2 = 2 ^ (1/41) = 1.017049 | |||
* 1/K + 1 = 1.983 | |||
* K + 1 = 2.017 | |||
F/2 is subtracted so that one can measure from the edge of the frets, not the center. K is a constant for all Kite guitars. F is a constant for a specific Kite guitar and the specific fretwire used for the new frets. (This formula works even if the original frets and the new frets are different widths.) X needs to be measured repeatedly for each fret added. | |||
Use either D1 or D2, or both, to place the fret. | |||

If one is instead cutting a fret-slot for a fret with a tang, D1 and D2 are the distances from the edge of the original fret to the center of the new fret slot. Use the same formulas, but measure X and F like so: | |||

Incidentally, these formulas work for any edo. Just change the value of K. If adding frets to a 12-edo guitar to convert it to 24edo: | |||
* K = 24th root of 2 = 2 ^ (1/24) = 1.0293 | |||
* 1/K = 2 ^ (-1/24)= 0.9715 | |||
K = 24th root of 2 = 2 ^ (1/24) = 1. | |||
1/K = 2 ^ (-1/24)= 0. | |||
