I need a larger oven then my current house oven to powdercoat my motorcycle wheels and swingarm. I am limited on space so i dont want a huge oven. Im thinking 2 x 2 x 3 tall. I also want to stay on a tight budget.

I was planning on removing all the guts from my house oven and transfering it to a new housing.

Since i am planning on using the wiring from my old oven, i was planning on using the heating element as well, just not sure if it is large enough to heat the new enclosure. If I need to install a larger heating element, what else do I have to upgrade?

Also, i was looking at installing this PID
Dual Digital F/C PID Temperature Control Controller - eBay (item 230390463509 end time May-18-10 10:03:35 PDT)


Ill have to figure out how to wire this in. Is it as simple as removing the currect temp control knob and wiring the PID? anything else i need to support this?

as for the enclosure, i was going to do a metal stud frame, pink house insulation, outside lined with hardi board, and inside thin sheetmetal.

Thanks for any and all help, im a complete newbie to building an oven!
