I've been pondering this here and there since I got my cnc machine. I wonder if I could plop a diamond grinding bit in my cnc machine and mill the frets with the desired radius - maybe even crown if I want to get really finicky. I'd almost certainly have to do it before shaping the neck so it is still a flat slab that won't bow for any reason. Would this actually be useful? Probably not, to be honest. But if I could figure out a good way to both level and crown them... Maybe it would be pretty cool.r Pobably throw sparks friggin everywhere tho. Anyone ever heard of someone dking this before? Did I just reinvent PLEK?
