Okay, so I went back out and tried it again.
Was working at a bright orange temp this time. I rearranged my forge last weekend and I think I created an air leak between the forge and blower, it just didn't seem to be getting as hot as it did before.
Anyway, I cut off the damaged bit and went to work. I got more cracks in the tip again, but they're different this time.
Is this the same problem or something else?
Thanks again for all the help.
