HEAT TREAT Batch #2
The same NOE 245-75 FN.
I used straight COWW this time.
I sized and installed the GC...This time I used a Lyman 45 to do that, instead of the Nose first technique I did before, the GC's look much better.
This is what they looked like in the first batch, that's why I discontinued that batch, and put this off till now.

Heated in tuna can to 400º for an hour, same as the first batch.
I'm hoping for a hardness of around 24 BHN.
BHN measured 17.9 an hour after heat treat.
I got called back to work, starting Monday...and thought I'd get these cast and heat treated, It'll be easy to let them 'sit' til spring, if I'm working.
