Chuck, I think that we are talking of two different chasers. The one I'm talking about is just for re-chasing some damaged threads. Hex shaped and usually turned with an ajustable wrench.
As far as turning an 8-36 or a 10-36 x 3/8" long or shorter in a lathe, I still find it almost impossible to do. Your cuts can only be maybe .002-.003 at a time, the tool has to be ground dead sharp, and dead on center. The lathe speed in conjuction with your indexing speed, and pull out time along with your tool post getting in the way. But if you say you can do it, who am I to agrue with you.
IMOP why you would do it this way, instead of using an acorn die, is beyond me.
By the way Merry Christmas
