The bassist in my band broke the nut on his old music man stingray bass. I offered to help replace the nut. Now usually I’d grab a tusq pre shaped and tune it up for optimal fit and playing. However there doesn’t seem to be a near fit for this bass. He had some brass stock and asked me to use that. I cringed. I’ve made brass nuts before but my finger didn’t enjoy it. I do not have dedicated nut files and use jewelers files, old strings with sandpaper and torch tip files. Ok for guitar, but bass? So I had this idea of using the old nut for measurments, plotting it out on the new one. Then, I would move to the drill press and drill the string slots in their corresponding sizes. Next I would do the final shaping, which include a radiused bottom (man I hate those) lastly I would angle the slots toward the tuners. I haven’t done it yet, it just came to mind. Anyone try this before?
