If swarf starts wrapping around the tool 1 inch into a 10 inch long

So what do YOU do in that situation

Hi Ian,
Thanks for your comments, and the link. Ornamental turning is fascinating.
Last year, somebody found a Holtzapffel lathe in a garage, here in Cornwall.

Er, actually it does use run from here. For example if you were to use
all incremental code from the tool change onwards it would foul up in a
big way. You
