O.K....I'm doing a partial refret on an older Gibson archtop...I'm getting a .070 width measurment on the old wire...I quadruple checked it , and checked it against my Martin/Fender wire in case my calipers was off...Nope...Now , I've checked Jescar , LMI , Stew and Dunlop...Not one of them have anything close to .070...Did they maybe get a funky batch of fretwire at Gibson ages ago ?...Never ran into this size on a Gibson or anything before...Any sources I don't know about that might have it ?
I measured the fret wire on a Gretch ukulele (Chinese made) which was .070. Might be a direction to look.
Philadelphia Lutherie carries Sintoms frets that come in .060 nickel silver, .065 stainless, .073 asymmetric. I believe this is a UK company. I have used them on occasion and they have held up well. Available in nickel silver 12%, & 18%, evo 15%, and stainless.
Also, here's a chart I've found handy. Maybe you can find something close. Mandolin wire is listed near the bottom of page.
Thanks...I did see that....
This is what I would do, take .080” width fret wire and file the width down to .070”. Taking an equal amount off each side, the best you can. StewMac has a fret barber tool that would also possibly work to thin the fretwire width.
