Dan Erlewine's Nut Making Step-By-Step DVD purchased from StewMac. There is no Japanese translation, but the editing is such that you can understand by watching. This is a very helpful product for those interested in guitar repair, etc. Due to home storage, there are some scratches on the package, but the disc surface is very clean. Please understand that this is a used item as I have watched it several times. The entire process is introduced, from removing the old nut, creating a high-quality replacement nut, to final shaping, polishing, and installation. • Neck Adjustment • Nut Removal • Finishing Marking/Heating/Cutting • Nut Slot Analysis and Preparation • Nut Blank Selection • Nut Blank Installation: Fender, Gibson, Martin Techniques • String Spacing Layout • Slot Lowering • Shaping, Polishing, and Buffing • Nut Gluing • Finishing.
