bg7m Posted July 9, 2008 Share Posted July 9, 2008 Here is a hunter I forged from a 1 1/4" ball bearing, stainless guard and spacers, stag handle. Triple quenched, triple tempered. I left the blade dark from the acid. Thanks, Buddy Quote Link to comment Share on other sites More sharing options...
Don A Posted July 9, 2008 Share Posted July 9, 2008 Very nice, indeed. How 'bout you give us a run-down on forging large bearings? I've got one I have had for 30+ years that's about the same size as you described. Can I assume 52100, or has that been around that long? Thanks, Don Quote Link to comment Share on other sites More sharing options...

bg7m Posted July 9, 2008 Author Share Posted July 9, 2008 I don't know for sure what you have is 52100. I've heard there are some stainless ball bearings, but I have'nt come across one yet. The balls I use come from bearing out of large electric motors. I first normalize the steel, then weld a rebar handle on it. I forge it in a coal forge. This steel don't move very good at the lower temp that I forge at, but I think it makes a better blade forging at a lower temp. I start forging the ball to a square shape about 1/2" square then forge it out to the blade shape. I normalize three times,anneal three times, grind to final shape, heatreat,. Hope this helps, Buddy Quote Link to comment Share on other sites More sharing options...
Don A Posted July 10, 2008 Share Posted July 10, 2008 Thanks, Buddy. This one's definitely not stainless. It came out of some heavy equipment at a limestone quarry. I'm gonna give this a try when I get caught up. Quote Link to comment Share on other sites More sharing options...

tantrum86 Posted August 25, 2008 Share Posted August 25, 2008 VERY NICE! i also have a few roller bearings out of a micon 700 gearbox (its a type of wind turbine) that ive considered forgeing but was not sure how feasable it was nice to see one done so well Quote Link to comment Share on other sites More sharing options...
bg7m Posted August 26, 2008 Author Share Posted August 26, 2008 Thanks, I've not used rollers. I've used ball bearings and had pretty good luck with them. The steel is a little hard to work by hand, but makes a good blade. Holds an edge well and very easy to re-sharpen. Quote Link to comment Share on other sites More sharing options...
Metal Head Posted August 27, 2008 Share Posted August 27, 2008 I'd like to know the proper way of heat treating,annealing,quenching,and hardening.from step 1 to?,made my first knife with a stag horn base and would like to learn more.any info will be helpful,by the way excellent knife.

ThomasPowers Posted August 28, 2008 Share Posted August 28, 2008 MH; first of all you have to tell us what alloy you used for the knife as heat treating is alloy specific For example: S1 does not profit from normalization according to the ASM volume on Heat Treating. Yet most knife steels are normalized for grain refinement. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted August 28, 2008 Share Posted August 28, 2008 Bp number 0078 is pretty good about what you are looking for..And like Thomas said deals with individual metals. Quote Link to comment Share on other sites More sharing options...
