Title: Parting tool trick
Post by: DICKEYBIRD on October 18, 2009, 05:03:10 PM: I think I saw this on John Moran's (Gadgetbuilder) website. You guys may already know this but I thought I'd post it anyway in case anybody's having parting sorrow. A simple mod but very effective!

Just grind a chip breaker radius into the top of your HSS parting blade with a small stone in a Dremel tool and hone the cutting edge SHARP. The results are amazing. Tiny, tight little curls of swarf and the blade just plain walks through the stock.

I know. I've got to prove it now right? :lol:

Used to work with a chap we called Lenny the curler, he could part a 1" bar off in one curl.

Have fun

Nope. HSS tool in a QC tool post. The secrete is getting it square to the work and a bit of "Tap Magic". You know how many I broke before I could do that.
