 Posted: Thu Oct 09, 2008 11:24 pm Post subject: Ideola's getting powder coated |
 |
|
Just picked up a used electric oven last night. I need to have 220 dropped into my garage, so I'm going to have one drop for the oven and hopefully a second that could be used for portable plasma cutter or welders or other big stuff I might eventually get. For those of you running your own home powder coating ovens, are there any safety concerns I need to be mindful of in terms of placement of the oven, climate control, fumes, venting, etc.? I have a perfect spot for it in terms of space, just want to make sure I'm not overlooking any safety issues.
Also, I still need to select a gun. I'm looking at units from Eastwood, Columbia Coatings, and Harbor Freight. Any recommendations? Any points to ponder in terms of features that are mandatory vs. nice to have? How about coatings themselves, can I assume the materials are universal regardless of which gun setup I get?
Ultimately, the notion of an infrared lamp is very appealing. I won't be spring for that initially, but the idea of being able to do large pieces without requiring a massive oven is very attractive. Anyone have experience with the propane-powered infrared units? Thoughts comments?
TIA

Do Not, under any circumstances, bake chicken or tuna casseroles in the same oven at the same time.
Cross contamination can be deadly.

Hey Dan- I have a buddy that has a powder coating system in his garage. I'll ask him some of your questions that you have. I plan on giving him some of the pieces that I'm getting from you for my 5 lug conversion to make pretty

Other than the obvious, not really, not specific to powder coating anyways. Other than don't use the oven to cook food afterwords, if you throw the oven away when you upgrade at a later point in time, destroy it so noone else can use it as a oven.

Coatings are pretty much universal, I personally really like the mirror colors that I got from columbia coatings. I have a columbia coatings gun, Its a inexpensive gun. And as such, it works, but it could be alot better. You can't tilt the gun at all because of the container on top and if you tilt it it stops sending out a good flow of powder. Personally if I was you, I'd get something similiar to the one I have and just use it for awhile, it takes a bit to get things to come out looking decent.
The things I would recommend, are things like, get a good silicon plug and cap kit, get some decent high heat tape, setup something for a spray booth that lets you recollect your used powder easily, setup a system for hanging the parts and easily turning them so that you can get a even coat on things. Evenly coating things is tough if your not hanging it and spinning it. I've learned that the hard way.
You also need a good supply of air, clean moisture free air. And for a home guy, this can be a bit of a trick. Typically to do powder coating you'll also need to do sandblasting, don't use glass bead or you'll get glass bumps in your coat.
Getting into powder coating can be expensive. Even when getting inexpensive powder coating equipment. I recommend reading the caswell forums. http://forum.caswellplating.com/ its got lots of good info.

Awesome, thanks for the feedback guys. I'm really disappointed I won't be able to cook pizzas in the garage though. Guess I'll have to get the Craigslist microwave next 
Seriously, though, I appreciate the feedback. I am planning to do most of my media blasting with various grades of walnut shell, as the research I've read indicates that it is excellent for most of the types of blasting I'll be doing (mostly small aluminum parts, with occasional steel pieces), but it is also very good from a re-usability perspective, from a health perspective, and from an ecological perspective.
I'll take a look at the caswell forums to do some more research before completing the setup.

I'd love to get my hands on a bag of walnut shell, I don't know a local supplier and was reluctant to order off the net.

I have an older box kiln that my wife bought for porcelain but it will only get up to about 800F. If anyone can use it, it is free but the transportation costs would be a bunch.

Why do powder coating? How's it different from a really good paint?

its like a hard plastic coating. Quite a bit more resistant than paint, doesn't smear if you get solvents on it, etc. Perfect for engine parts.
