I built this oven a while back, but I couldn't get it over about 275 degrees. I recently added a layer of R13 insulation to the inside, and now it gets up to 400 no problem. It takes about 30 mins to get there, so a total cure takes 50 mins. I did one test part (an old water pump impeller) and it came out great.
I used the control circuitry from an old microwave/convection oven to turn on and off a 3 element quartz heater (about 1600 watts). I just set the temp for 400, the time for 50 minutes, and it beeps when it's done! (and turns off) I still have a few kinks to work out (like a structure for the ceiling to hang things from), and I need to get better at the application of the powder, but at least I can get up to and hold 400 degrees.

(IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) I have been considering building a larger oven to fit fan shrouds and 17" wheels in but don't have enough electro knowledge to get started (or time). I have thought of using heating elements from 2 kitchen ovens combined with the fans and sensors. Anyone have an opinion on this method? I have NO idea how an oven werks as far as temp control but I fiigure once I get it apart and lookey loo it is pretty simple.? Box would be a piece of cake,18 ga. w/ insulation sandwiched, it's just the electronics that I hesitate on. I want it to be controllable for doing head jobs, heating gears, wrist pins, etc
