I noticed you can by powder coating spray guns etc. Anyone here use one? and is it worth it?
Anyone here do their own powder coating?

This is an interesting topic.
I'm in the process of building my own powder coating oven. It is about 75% done. Frame is 2"X2"X2" 20 ga. galv. sheet metal channel, MIG welded together. The sides will be covered with 22 ga. sheet metal snap-riveted on with rock wool oven insulation in the middle. Inside dimensions are 72" deep, 36" high and 24" wide. This is designed as a dual purpose oven for both powdercoating motorcycle frames and other parts as well as some pre-heating and heat-treating for welding. It's capable of up to 500 degrees F. I have been powdercoating small parts with a toaster oven for some time and we typically will use 450 deg. F. for a half hour. Results are quite good using an inexpensive gun presently, although we will be upgrading when the big oven is finished.
I'm going to be using 4 2,500 watt oven elements. These are controlled by a 110/220 relay (definite purpose contactor) and an oven thermostat. We have 4 conductor 6 ga wire to the machine so I anticipate it will be OK. (Please, please don't start a discussion telilng me that i will need 4 "0" gage conductors Hahahahaha.)
I'll try getting some pictures on here soon when I figure out how to do it. Ha.
For some great insight to how to do this yourself, the link below shows how one fellow handled the problem. He used foam insulation which would be very good except for the cost in my area. He also makes great use of his sheet metal tools - and skills which are really very expert. This website has been an inspiration to me and the fellow who operates it is more than willing to help others who are interested. His website is the only one I've found on the internet that shows how to do it. In particular his wiring diagrams, material lists and general philosphy on the topic. By the way, he does not feel that a blower is of any use in this size cabinet and he's been doing powdercoating for some time without one.
The nice thing about this project for me is that it's motorcycle-related. That's how I got started welding. Also it makes use of other tools you may have (or want to convince your spouse that you need!) such as lathe, milling machine or mill drill, MIG, TIG and arc, not to mention OA cutting and brazing, all of which I have used so far on this project.
Coimments, scorn, disrespect and screaming are welcome. I'm also an attorney so I have a very thick skin.

Oven Photos.
Here are a couple of photos. This shows the scope of the project. It's pretty big.
You can see how the oven elements are arranged in the bottom tray of the oven. There will be an oven control box on the side of the oven with on-off switches and LED's to indicate power on and when the oven is heating.
It also uses two oven windows in the top and two oven lights on one side to see inside when the oven is in operation. All of the parts came from a local used oven repair shop at very reasonable prices.
The worst part was buying the sheet metal which is very expensive. I don't have it on yet, except for the bottom pan but it cost me $300 for the metal alone. Insulation is $40 a bundle. Rock wool is used in home oven manufacture and melts at more than 2,000 deg. F. so it should do for this project.

Powdercoat oven
Here is my oven I recently built from the website mentioned in the previous post.I have used it for motorcycle parts and have had good results with it.I built it for around 800.00.I have the Eastwood hobby gun.If you guys want more information about powdercoating and oven building,I suggest going to Eastwoods website and checking out their forum.
