She's remodeling the kitchen, and is replacing all of her appliances ($$$OUCH!!!!$$$) BUT, at least I scored the old oven for the garage - now I can powder coat at home without fear of ruining tonight's pot-roast. The only down side is giving up the real estate for a (relatively) rarely used item.

Well, I suppose it'll make shrink-wrapping easier too.

Any other uses come to mind?

Curing ceramic coating at 500 degrees... Heating a stubborn supercharger pulley that won't go on the output shaft, heating a snowmobile crank bearing to fit on the crank shaft, outgassing polished aluminum so that the clear coat does peel off or oxidize as easily, lots of stuff!!!

I have to say though, once you get powder coating down and show it to your friends, you'll be doing a lot more powder coating for them!!!

 

Could you go into a bit more detail explanation?

 

Metal has small pockets of gas that gets trapped inside during the casting process. When the metal is heated to a certain temperature (temp changes for any type of metal compared to another type), those gases release to the surface. In some types of aluminum, that temp is right around 400 degrees.

If you polish an aluminum intake lets say, you can heat it to 400+ degrees for around 20-30 minutes to force the gasses out, then let it cool, then put a clear powder coat, cure it in the oven at 425-450 (or what ever powder curing temps your powder requires), and the clear will last much longer without lifting.

One problem with outgassing though is that it will remove heat tempering. From things like wheels, that is a very bad thing, so it can't really be done unless the wheel is made from a high temperature treated aluminum alloy that heat treats at a higher temp... It's funny how much metalurology (SP?) you can learn just coating stuff...

 

Heh that would be an awesome convenience to have...I wish I had an extra oven sitting around, I'd start learning how to do some of this stuff.

 

thanks for the info!

 

Good call on the stove, at least you won't have to explain that "funny" smell in the future.

 

Good score dude, I wish I had an oven to cure and bake parts. I used to have an old bbq grill to do it, but I set it next to the trash and well, got taken away.

 

how do you powder coat? and where do you get the stuff, about how long does it take? i'm very interested in the process.

*edit* also, is it as strong just as when the "professionals" do it, as to when you do it?

 

eastwood.com

check out eastwood they have all kind of cool guy stuff as the misses calls it. powder coating polishing painting ect...

good score on the over now all ya need is an electricain to wire it up.

 

Just had him out last week putting in a 220 line for a welder (yet to be purchased) so I'm gonna be ok, I think! (as long as I don't weld and powder coat at the same time, anyways...)

How well do home oven's work for powder coating? My new house has 2 220 outlets in the garage .

 

Works real well! Have done alot of parts at my uncles with a home oven, just make sure it's electric....
