Kevin (Rooster1) and I were talking on the phone about mistakes that are made. I go in spells of everything being fine and then I cant touch a blade without cracking it or it warping or SOMETHING!
I forged and ground a 10 inch blade this past week and Monday cracked it in the quench. Kind of turns your stomach a little. I did successfully quench two hunters, but was sure counting on that big blade.
I'll probably get out there Saturday and forge two or three 10 incher's and work them all up together. It seems to me like I can do better in batches IF they are the same size blades.
One thing that may cause a problem when quenching a bunch of blades is that you might not give each blade enough individual attention and let the heat get a little too high or something. Also, I think the temperature of the oil climbs with each quench causing more risk on the ones later in the group.
I know the reason why the 10 inch blade cracked. My fault. I had a small hammer mark on the edge of the choil that I was planning to get out in the finishing grind and it caused a stress riser and cracked about a half inch into the blade. It pays to get the edge smooth and rounded to about 220 grit before quenching. I never had one crack in the choil till now. If one cracks, it's usually in the sweet spot about 1/3 in from the tip.
Sorry to ramble. Were operating by generator and my inner clock is messed up. Trees down on powerlines. :rolleyes:
