Chuckle, Steve. You obviously have at least 20 more HP in spindle drive than I. And because you are carrying away the heat with a much more massive cut, you are probably getting 200x the life out of a carbide insert. Most of my "heavier" turnings seem to curl up and spiral down the center of the bed, in 6 foot long spirals, cutting about .004" square swarf and I'm out of motor. That and off the front, in my face or shirt if I'm wearing one. Either way I pick it up in big handfulls for the trip to the barrel.
