To make a long story short, I have purchased some 7/8 14 threaded rod for making die sleeves that I thought was mild steel but turns out to be B7 steel. I can machine it but I cannot cut internal threads in it. So, my plan is to anneal the rod (after cutting into die length chunks). I am on a very tight budget and cannot afford to build even a cheap gas forge. So I have been looking into the feasibility of using a charcoal forge for annealing this rod (I also have a bunch of bowman 7/8 14 bolts that I would anneal if I could. I know that it is not the best to be chucking threaded rod into a lathe but I have found that if I use an aluminum sheath around it and not re-chuck it, it is good enough for my work.
Do any of you have experience with annealing threaded rod? Is it something that can even be done on a charcoal forge? My plan was to try and do as many chunks at once as I can and just let them cool with the cooling of the forge after stopping the blower. Hopefully this would give me the slow cool that is recommended.
The dies that I make are just for lead boolits, making the dies for jacketed bullets is beyond my skill level.
Thanks for any and all info.
