I've never really been a fan of powdercoating, mainly since you have to give up control of the project. But since I got started on my new pre-unit project I've been giving it a hard look. (Robbie, I know we talked about this!)

Anyway, I figured if I could do it myself it might be worthwhile. A fun project if nothing else. SO here goes: First I got a double oven off of CL; figured I could make the thing one large cavity.

Job one is the teardown

After removing the porcelain-on-steel oven boxes, I cut the facing ends like a "T"

Spread the panels and reinstalled

With the original rock wool packing of course

If you're just cooking for 10 minutes after the powder flows out, you're undercuring the powder and it won't be as durable as it should be. Get yourself an IR thermometer, and don't start your "time" until the part itself is at cure temp.

That is actually what I do. I wasn't really trying to give instruction, just an overview.

I also preheat the parts before I shoot them.

What the hell did you tell your Mrs happened to her oven, and live. LOL

lol my wife is pretty cool about this stuff. After I got the gun she said, "just go ahead and cure it out here in the kitchen"

What did you have to do to mount heating element for upper oven? If I end up with a convection oven, think the air circulation might cause dust blems in finish during curing?

Huge thanks for your post. Just what I need...and can afford!

I dont like handing my jobs out to powdercoaters either, and im not the best when it comes to patience needed for a quality paintjob..... this looks way too cool. Im on the lookout for an oven

Could you use a really old refrigerator and fit a heating element or would that be more work? Obviously you'd remove all the plumbing and any gases

Charlie, I just mounted one element at the bottom, one at the top and one against the back. For the back one, I just bent it 90 degrees in a vise. I can take pics if you need. As I turned out I get the best performance from the bottom and back ones running; I don't think I'll ever use the top one.

Actually I would have liked a fan, the commercial ovens all have them. If it's a concern you can always cut the wires to it.

Harry, I don't think a fridge would work- they usually have a lot of plastic parts. A lot of guys just make the box from scratch out of metal framing studs and sheet metal. For ideas you might check out the forum at caswell.com; it's a very slow forum but there are some oven build threads.

Would the really old fridges have plastic parts? Im fairly sure, but not certain that i used to have an old fridge and it was metal lined on the inside and quite large with a solid door

Without seeing what you have, all I can say is if you have a metal box that can handle heat, it would serve as an oven.

I would take a good look at the door seals though...I don't think I've seen an icebox that didn't have rubber seals. I suppose you could replace them.
