Build Your Own Powdercoating Oven Tutorial
« on: May 03, 2020, 04:01:58 PM »
Hey Saberland,

Recently, I’ve come to the place where I need a larger powder-coating oven for the various projects I’ve got outside of saber smithing. (Restoring vintage tackle/tool boxes) While Toaster ovens may meet your powdercoating needs, I wanted to share this tutorial/build log on how I’m building my own powdercoating oven just in case you need something... bigger.  :cool:

Basically, building the oven is two parts
1. The Shell- which will be steel and insulation.
2. The Door- Using a latch, hinge, and fiberglass insulating strip.
3. The electronics, which essentially is just a heating element, controlled by a PID. We will add some indicator lights, temp probe, etc too.


Specs- This oven will have the following Specs.
- ~24”Lx24”Dx24”D
- 110V Power supply
- 6 Cubic feet of Baking Space. Google says for ovens, we need about 100 Watts per cubic foot for the heating element.

Parts List- I got most everything at Home Depot/Lowes
1. The Shell
- Sheet Metal. I’ve bought 24x24, and 24x48
- Steel bar stock
- Fiberglass insulation
- Lots of Pop Rivets (how we will attach the metal to the bar stock)
- Aluminum Angle Stock
- Red High Temp Sealant
- Steel Screws

2. The Door
- More Sheet metal and Bar Stock
- Fiberglass flat Gasket Replacement Kit
- Latch Action Toggle Clamp
- You could install high temp glass if you wanted.

3. The Electronics
- Inkbird PID controller Kit
- 14 Gauge Wire
- Indicator LED
- Heating Element- I’m using an  oven replacement. A heater coil is simply just a resistive load. A 220V rated Element being run at 110V creates ~1/4 power. So, in theory, this should pull ~6 Amps, and provide 650Watts of power. btw- please tell me if my maths are wrong.
- Latching Toggle Switch
- Wire ties and Spade Connectors

We are going to walk though assembly and wiring of everything in the next couple weeks! Here are some pics of everything laid out. Once the welding rods are ready for pickup, we will start getting it put together!
