Crimson: Thanks for the input. To answer your question. If I divided my oven with a wall, I would only have one and a half feet to work with, as I opted to build a 3x3x6. But a divider has been considered.
RobsPCing: I have the old oven I got at a yard sale and it works, eeeh, okay. But it won't hold the temp at the same spot on the dial every time, making it a pain. The reason I'm not keeping the oven, is it's to small and I tend to bump items I've coated and burn myself!
Yea, I know, "dummy!"
I did a little checking around today and found that I can get my steel cheaper then I got the first batch. About half the money. And I think I'm going to be able to get the insulation locally. So building looks better all the time. Just don't have to be made a heavy duty as the big one.
Still contemplating.....
