Ahhh This brings back personal memories
Thanks Don for the report.
It is almost unbelievable that I remember using 'sacrificial' coal powder, heating metal to cherry-red, quenching and also annealing at metalwork class before I decided to become a heart transplant surgeon! I was young....what did I know? The skillsets seem similar.
Actually, I never became a metalworker nor a surgeon but an anaesthetist (anesthesiologist if you are American) and later a clinical pharmacologist.
Of course, we only worked with great big chunks of metal like hammers and tongs; not itsy bitsy teeny weeny pinions.

Fantastic report, Don. Working on such a part is not a small affair!
I am always impressed when I see what they can do from a piece of metal. Almost Art! Best, Nicolas

Thank you, Don!
Thank you for showing and explaining how difficult even the smallest part is to create! Best Blomman
Excellent post Don
I had been wondering if the Sandvik AP was oil hardening or not like O-1, now I see it is. By annealing- I think you meant tempering, no? :) Wonderful post, it's nice to see someone doing it the old way. -O
That was phenomenal
Thanks for getting this information to us. It boggles my mind! Mike
Mind boggling!
Awesome post! 👏 With all the steps involved I was surprised it took 2 hours. I would’ve guessed at even more. Fascinating. Thanks for posting 🙏
