April 2, 200917 yr I was just given a box of high speed steel cutting points for a lathe, most of them are ground for various cutting purposes Not having a lathe, I am looking for some other ideas.
April 2, 200917 yr High speed steel was developed to retain it's hardness at red heat. It actually gets harder from 700* to 1000*. Annealing temp is 1600*. Hardening is done by preheating to 1550* throughout, then rapidly heating to 2350* before quenching in oil for large pieces. Pieces less than 1/2" may be air quenched. Temper at 1050*.
April 2, 200917 yr You could hang on to them and get a lathe when it's feasible! What size square are they? Lathes are a handy tool to have. I have two. Dick
April 3, 200917 yr Author I could be so lucky to get a lathe, most look like a 1 off cutting tool, most are about 3/8 sq and ground to various cutting profiles.... more than willing to trade for any stock or service...
April 3, 200917 yr Although not expensive as cutters, they are still MUCH more expensive per pound than tool steel for use around the blacksmith shop. You should have no trouble at all trading for some springs, S7, H13, etc., at your local blacksmith group meetings. It isn't unusual for people to drop off machining stuff in my shop for some other steels more useful for forging, so I'm sure your New England groups have people with similar needs.
