Reading tomme boys heat treating thread gave me a question.
Has anyone ever ran their heat treating oven with a PID?
I do not have a PID, they haven't really seemed necessary to me just for casting. Likewise, I don't water drop or oven heat treat. ACWW does most of what I want to do with cast boolits, so this is mostly theoretical for me.
Since every thread or article I can remember reading has stressed testing the slump temp of your alloy since oven temperature settings are unreliable, doesn't it make more sense to use a PID to control the oven?
Seems like it would be ridiculously easy to install a thermocouple and wire it in.
