I have a 1" ahank which is hardened that I need to turn down to 3/4". On one end there are threads and a flange that are dimensionally critical. If your procedure is followed for heating and cooling, etc. will the dimensions hold true without any defromation?
Thanks for the multiple ways to indicate the correct temperature, but was wondering exactly what temperature it is. 1150F maybe ?? If I were to need to anneal pieces often, such as in fold forming, I'd prefer to use the burnout oven and would like to set it to the proper temperature.
I think you need to work up the piece of metal to insure overall heating. It will raise the temperature above minimum proper temperature however you are not doing excessive overheating. The point is softening is at a lower temperature than what most conventiona😢wisdom says.

Simple easiest example I have seen. The yellow orange flame bouncing off the metal is a gem.
Amazing explanation!
Thank you!
Amazing.

Wonderful information! I'm self teaching, and always thought the "cherry red" term seemed WIERD!

annealing in our meals begins around 800F, metal begins to glow around 900F
I have no idea why there are so many posts? Sorry! Also, I thought once up to temperature (hardened steel) it was supposed to cool off very slowly.
Why did you keep heating it after the flame turned orange? Aren’t you supposed to stop once the flame turns orange to prevent overheating?

works better if you don't annealing the metal while sharpening it... chill out on that heat
Why aren't you wearing eye protection. Loved the video up to that point.
