Fret Crowning Tool DIamond

thingiverse

i printed the original design and used sandpaper to crown some of my frets but had the worst fret job ive ever seen on a squier neck so I added a slot for a small rectangle harbor freight file. That worked ok but left some file marks that i had to sand out. Looking on Amazon i found a cheap (8.99) HTS rectangle diamond file set so made a version to hold those which worked amazingly well and had even the flattest top frets crowned in no time. I used the 240 on one side and the 400 on the other then switched to original design with sandpaper. I recommend watching the Guns and Guitars video on DIY fret crowning to see how these are used and the Addicted to Gear video on fret crowning..the way he final sands really made my frets look uniform and shine!
