First off the old nut was carefully removed before the new nut could be cut, shaped and fitted.
The bone nut blank was then thicknessed to the width of the nut slot, then shaped down to the shape of original nut.
The original nut was used as a guide to ensure that string spacing on the new nut was exactly the same as the original removed one. The slots depths were cut once the guitar was restrung.
The final step the new nut was smoothed to a shine with fine abrasives.
The same process was used to make the new bone saddle. A bone saddle blank was cut down and thicknessed to the fit of the bridge saddle slot.
The radius was copied from the original saddle, the compensation pattern was then marked out on the bridge and filed by hand to match the original.
The saddle was then smoothed used fine abrasives. The final height of the saddle was set once the guitar was restrung. This process of setting up the guitar was done to the exact action that was originally on the guitar.
