Geoff, headed out to the base near Spokane. I've heard lots of good stuff about the base, so I'm hopeful. And thanks for the term correction (truly not being sarcastic, I'm just on my phone, so my brain is a little off). I'm familiar with the process, as I've hardened 1018 a bunch of times in the past for home made bits (I'm often too cheap to get tool steel, and have ready access from the local shop of off cuts), but, I had to learn it trial and error until my father gave me his old handbook, a 26th edition (he's an engineer). I apprenticed for a smithy in Germany for a few years, so I was able to get the basics, but as a machinist, I needed a better understanding, so I started experimenting.
