I have a nearly new Ibex fretscale ruler you could have for £10 plus postage: But - it doesn't have any of the common fretscales on it which is why I have never used it: Steel String: 25 11/32" Steel...

I've got this jig ....25 or 25.5 " scale length thatI had before I bought one of Bagpress's excellent fretboard cutting kits. It's yours if you want it... Pay as you feel plus postage 😉

I bought my tusq nuts from ebay. Graph Tech part no PQL-6010-00 Attachment : Screenshot_20231027-194700_eBay.jpg
