Great show, as always! If you are interested, there are a few chemical ways to remove the mill scale. The most common is using a solution of sodium bisulfate. It works quite well, especially on heavy forge scale. The section on peel grinding was excellent. I’m going to give it a try tomorrow. I did notice that Adam recommends a maximum of 1/2 grain diameter in both depth and crossfeed. Keeping the depth to less than 1/2 grain diameter might help improve the wheel wear characteristics. Thank you, and keep up the great work!
Thanks for the nice words, and the feedback. I talked to Adam and another practitioner of peel grinding. Adam said that one-half grain size (on the order of 0.007") happens to be about the stock left after heat treating in his work. So, he has not had to push it. Another source said they also generally don't need to go more than about 0.01" deep either. So, my comments that you *can* go deeper is untested, and is speculation on my part. Might have to try it.
