"Modification Of The Toaster Oven And Final Tips"

The toaster oven works well. I would like a regular oven but I'm severly limited in the space I have so this will have to do.


All toater ovens have one major problem. The rack is designed to slide in the bottom only not allowing you to hang parts in the oven. The rack must be able to slide and stay in the TOP of the oven.

[PIC #1]
Here's what I did. I took the oven apart so I could access the sides of the interior chamber. I drilled holes through it and attached machine screws with nuts. The screws protrude into the oven giving the rack something to hang on. I was lucky, I only needed to drill 2 holes since the stamped contour of the interior chamber supported one end of the rack on either side. The rack hangs down enough where it doesn't touch the upper heating elements. The oven was reassembled.

Here's what I mean about the rack mounted in the TOP of the oven now. In pic #3 of my above post with the toaster oven, it shows the rack sitting in the bottom in it's normal location. This won't work for powder coating. Regular ovens don't have this problem since they all contain multiple "ledges" for different rack heights plus with all the space you can hang parts and not worry about them resting on the bottom of the oven. With the cramped quarters of a toaster oven this problem comes into play.

[PIC #3]
Here's what the rack looks like and one reason why the oven won't be used for food anymore. Notice the rack is black and not the silver color? This is the stray powder that got baked on. You're just not going to scrub that off easy!

Final Tips:

If the part you're doing is oily or greasy, bake it for several minutes after cleaning it the best you can before hand. This will loosen up and allow some of the oil/grease to "bleed" out of the pores of the metal. Once the part has been baked clean it off again removing these contaminates before powdering it.

You can do one powder on top of another, scuff the bottom one first after it's cured. When do you want to do this..........when you want the color to "pop" or appear brite. If you're doing a light shade of green, blue, or red for example, you could first powder the part with silver to give the final color an extra "kick"! Also powdering with silver first is a must when you're doing translucent colors. It allows them to achieve thier brilliance.

Depending on where you're powder coating you may want/need air circulation. Remember, you're melting plastic so you'll have that burnt plastic smell. Also some colors smell more than others. I use my toaster oven outside, not bad, I've used it in the garage, ok, but I won't use it in the dinning room or even the basement. I don't want my rugs or furniture smelling like I have a plastic injection molding operation going on or had an electical fire.
