Greetings,

The Neycraft furnace has a built in thermometer.

The spring is coated with Keepbryte before it is put in furnace. The compound keeps it free from any scaling. I use it on all my heat treated die parts. Parts stay just as clean and bright as before heat treating. Made by Kasenit.

Polishing before drawing is not neccessary unless you want the spring to have a beautiful even blue color.

Sorry I forgot to mention Keepbryte in the process. One of those steps that I do without thinking about it.
