You didnt state wheather this was for home or commercial application but heres a very simple and economic way of doing this. Ride around on trash picup day and look for the biggest oven you can find. Usally if they dont work its easy to fix. All that you are looking for is that both oven elements work and the thermostate works. If after checking you dont like the one you have just sit it out for trash pickup and go find you anouther one. I would look for a stand alonen or wall mount unit myself. Remove the racks and install some eye hooks in the top and make some stands for the bottom so you can place your items in the oven suspended. Now dont plan on using the one in your kitchen because you have to stay on good turms with the better half and besides you may not want to eat out of your powder-coat oven. Keep in mind the temper in some metals can be affected at this low temperture.

www.jamestownpowder.com is a good source for your powder coating
questions. Our shop made oven is a simple fire brick affair. Fire brick
can be purchased most anywhere brick is sold. For heat we chose propane
to fire a burner scavenged from a dead water heater. The use of any
oven thermometer will do to monitor interior temperature.
Hope this helps. Del Sol Engineering.
