I did that and it went swimmingly well. In fact I now have a new set of 3 + 3 chrome Gotoh 510 Deltas less two threaded bushings. I'm going to have to try to see if there is anyplace to just buy the bushings.
And I deciede I still wasn't happy with the nut, so I went ahead and made a new one out of the bone blank I had. My problem was I had done all the calculations to get the right string spread with equal spacing between each string, but I didn't execute it very well. The spacing was not quite equal and a couple of slots had a slight angle, and the two E strings were just a tad closer to the edge than I liked. And finally, the three high strings settled or cut or somehow ended up a little deeper in the slots than when I first set it up.
Anyway I decided a guide for my nut files was called for. I set my calipers to the space between the strings I wanted and cut a small piece of bubinga. I sanded it to the proper width and cut a slot to fit over the nut blank.
Then I used it for a guide to ride my file against for the first slot. For the next slot, I left the file in the slot and used the guide to file the next slot.....and rinse and repeat right on down the line.
I was quite happy with the results.
This final shot is out of focus.....sorry....and the extreme close up and perspective makes the center space appear a little wider than the rest. I suppose it might be...but they are all within a gnat's ass (roughly the same as a bee's dodger) of being the same.
I took over to Hook's (Skullsessions) studio last night and got some audio tracks recorded.
Stay tuned......
