David, I hope your surgery is easy with a quick recovery. My wife just had knee surgery for a torn Meniscus. It went well and she has fully recovered.
Thanks for clarifying drill rod. tool steel and S7. And thanks for the offer to finish it if I have trouble with it. Fastenal has short lengths of both tool steel and S7 for under $4 so I might just buy both and see. As Craig says I will try to have fun with it. If I cannot do it I just might contact you. I think I will know as soon as I put file to metal.
