I was reading a post asking some questions about this subject. I didn't want to hi-jack the post but had some questions too. Why does everyone want the TAP control vs the Cheapie 3 button? When you heat treat do you put knife blanks in as oven is heating or after its heated? When doing "Stepped" heat treats do you take blanks out as oven cools or heats, and (i assume) once it get to set temp that's when you start timing the blank? Obviously never had a heat treating oven, these are questions I've really wondered about though.
