[How-To] Beginner Question: How do I Turn a 5/8" radius on the Lathe?

[rwm]

If you could get 5/8" diameter round inserts, you could grind a flat on it (remove some of the cutting edge circumference) and rotate the insert so only 10°-15° are in the cut. Then rotate the insert 10°-15° and cut that portion. Repeat until you achieve you full R. YMMV

This is actually brilliant! This could apply to a lot of situations. I have some round inserts. I will be trying this.
