Spent 9 hours chasing a cold shut that was really just my hammer face
Honestly I wasted most of last Saturday on a 1084 blade that kept cracking along the edge, and I kept blaming my quench. I renormalized three times, swapped oil, even checked the temp with two different thermometers before my buddy swung by the shop in Lansing. He took one look at my hammer and pointed out the face was crowned and pitted, so every blow was pinching the steel instead of flattening it. Nine hours of quench panic for a two minute fix on the grinder, and I still feel dumb about it. Has anyone else traced a forging flaw back to their hammer instead of their heat treat?

I swore for years that every edge crack was a quench problem, and I'd rebuild my oil tank setup before touching anything else. Then a guy at a hammer-in in Kalamazoo pointed out my cheap cross peen had a face like a golf ball, and the cracks stopped once I dressed it flat. Now I check my hammer face before I even look at the quench tank.
