Nope, no cookin' in the house!
You're not supposed to use an oven for powder coating and food prep. One or the other, just not both!
I have an old freebie electric oven that was given to me by an in-law that lives nearby. I asked him to keep his eyes open for one and a few weeks later he shows up at my house with a buddy and unloads this oven that he found for FREE. A homeowner was updating her appliances and just wanted it out of her house, she said it still worked.
I pulled a new circuit out to the garage and tried it out, it worked like a champ! I got my powder off of Ebay and the gun is from Eastwood. I use my smaller Hitatchi compessor to feed it and an IR thermometer to keep an eye on the temp of the oven and the part that I am actually coating. I plan on building a purpose-built spray booth with filtration and I would love to have a larger oven!
