Default Re: Mill/Lathe

I've got the cut dead smooth and within .0005" or less by using a flat faced cutter and just letting it barely touch the work, keep rpm low and just feed in enough to where it's producing really tiny shavings.... basically, as soon as you see it produce any sign of shavings, stop the feed and then make 2 or 3 passes, if there's still lines and striations feed in again just enough to see it cutting and make more passes.
Also, if you have to make your own cutting tool, grind it so the cutting face is about 1/8" to 1/4" wide with a very gentle curve to the face, the curve will help make the cut super smooth.
