Thanks CNC dude.
If I was building a V8 I would not want to hand file all those rings, but with my Harley we are just talking 4 rings to file. I don't mind if it takes a while. I could still do it faster than it would take to get the hand crank grinder shipped to me.
I am looking all over for the proper technique for hand filing piston rings, but I can't find anything at all. I know to file toward the inside of the ring and that's about it. I can't even find the proper hand file for this job!
