Fender Strat stock factory cyclovac nut remove strat nut sideways with punch
1. A Fender Strat.  This one needs a new nut.  The owner has opted to replace the original cyclovac nut with one made of nylon. 2. Removing the Nut with a 1/8” punch (actual dimension is .108”) doesn’t damage the fragile stub of fretboard at the headstock end of the neck.  I first scored what was left of the finish all the way around the nut with a sharp razor blade.

3. Layout is Key.  I trace a 9.5” radius onto the face of a 1/8” thick by 4” wide sheet of 6/6 Nylon with a fine-tip sharpie. 4. The Bandsaw gets rid of most of the waste.

5. The Oscillating Spindle Sander sands the bottom of the nut to a consistent 9.5” radius.  A second bandsaw cut parallel to the first cut frees the nut blank from the sheet. 6. A Sharp Chisel removes the burr of nylon created by the bandsaw and oscillating spindle sander from the faces of the blank.

Final Sanding the top of the nut with 180, 400, 600, 1000 and 2000 grit sandpaper wrapped around a cork-lined sanding block.  I polish the top and sides of the nut with a small grinder equipped with buffing wheels.

13. E-Strings Layout.  Since this guitar was shipped here sans body, I will copy the location of the E-strings from the original nut. 14. Notching the E-Strings with a .012” nut-slotting file.

15. More Layout with the graduated nut spacing rule marks the 4 inner strings’ nut slots. 16. Sawing the Nut Slots to their rough-depth and width is necessary because nylon does not file easily with nut slotting files.

17. Small Saws.  I use the set sold by stew mac for nut-work as well as a Japanese pull saw with a .035” kerf for the 6th string. 18. Final Shaping of the Slots with nut slotting files.
