Wish I could answer your questions but unfortunately at this time I can't. My machinist friend just got my one sample recently and will get back to me after he has assessed what's involved. I've never rushed him in 25 years and don't plan on changing that, I would expect I will have my answers in a week or two. I can't answer for him but I personally don't see the point of processing a grade 8 bolt further? What would be the point?
No worries I wasn't rushing anything I know how long the process takes as I have made multiple sets before..I was just curious as to what material you were using and whether it was going to be hardened..I understand if you can't answer that.
