Powder Coating W/O an Oven Part 2: Framezzzzzzz!

Some people noted that in my first powder coating experiment that the parts I coated could have easily been done in an oven or even a toaster oven. This is true, but the main reason that I coated them with this method, was so I could see if a larger object was even possible. Today I can proudly say this it is, and that my Magnum frame is coated and glorious. I used the same method as I did in my previous post. The only changes I made, was that I had to reposition the lights every 20 mins or so, and there was the precarious repositioning of the frame that I had to do mid-coat. Over all though, this was easy and only took a few hours while I was working on other projects.

Here’s a link to my last post:

Tips that I would have found helpful:

PREHEAT! Obviously you can’t preheat the whole frame, so I started where there was the most metal mass and moved about 6 inches down the frame each time I repositioned the lights.

Construct some kind of ghetto spray tent. I just hung some plastic around where I was working, and it did wonders to decrease my clean up time, and keep out contaminants that mess up your finish.

Move slow. If you jump too far ahead each time you reposition the lights, you will get weird areas in between with inconsistent finish.

This should go without saying, but please use a good respirator with a fine powder cartridge. I used one all weekend and I still got some of the powder in my lungs. Frowny times.

When the powder first flows out, it will look orange peely. Give it another 10 mins to flow more before you decide that you application method needs work.

If you spray paint after, let the coat sit for at least 24 hours. I made the mistake of clear coating immediately after my swing arm cooled down, and I got small, barely noticeable airline cracks in the finish. This did not happen on he pieces that I clear coated a week after I powder coated them.

Picturegraphic time!

So basically, I have already recouped the cost of all my equipment, because a pro version of this job would have cost way over what I threw down for all of this stuff.

Go forth and create!

That shot of the magnum frame scares me. No wonder they crack.

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

Awesome!

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

Wow, that works really well!

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

totally looking for a gun to do this with...

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

Real good work.

What system are you using?

About how much powder did you use for the frame?

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

If you take a look at my previous posting, you can see the deets on my set-up. I used a Eastwood Hot coat gun. They are about $90, but worth it. Don't go harbor freight on this, especially not for the powders. I got one pound of powder and it did the frame, swing arm, a set of handlebars, and a head set for a bicycle. I still have more after all that! A little powder goes a long way, so there's no reason to get the cheapo stuff.

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

Dang. I'm gonna have to get the set up. I already have the airbrush compressor. Gotta look into getting the gun and powders, how pricey were the lights? I know big ass heat lamps can get up there in $

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

I am always willing to do a cheap experiment. How about preheating the frame and then dusting it with powder out of some pantyhose. Then heat it seriously. Might be good for flat stuff but a vertical surface would have to be moved more horizontal

The trick is to get a positive charge from the powder to stick to a negative charged object. Probably on a flat surface, yes might work. So how to charge your panty hose!!!

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

i just bought a gun on ebay for 60 bucks, i went to powderbuythepound.com and got a couple colors, the average is like 12 bucks for a pound of powder, which on the site says can do about 100 square feet. shop lights are pretty cheap, like 20 bucks for the two lights if you look in the right place. the only thing I'm concerned with is preheating. its still cold in utah and I'll be powder coating in my friends cellar.

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

Oooo! Tell me how the finish on those powders comes out. Not all powders are created equal. Specifically those from HF. If you're doing steel parts, pre-heating shouldn't be too hard. Aluminum is only tricky because it dissipates the heat so quickly. Just start by coating your whole wrench set trying out different application and curing techniques. By the time you're done with the metrics, you'll be a pro! oh yea, also make sure you use a respirator the whole time! even when you can't see the powder in the air. Your lungs will thank you.

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

oh yeah, respriator.... maybe a bandana would work, haha. I got a form of black called black magic, it has a picture of it done on some rims and it looks sweet. its flat, but kinda buttery i guess would be the way to describe it. in fact, maybe half the colors on the website have pictures of them applied to various things, take a look around, I found it pretty impressive.

Re: Powder Coating W/O an Oven Part 2: Framezzzzzz

I've heard about curing with lights that you can get the powder to flow out, but that it will never fully cure. Uncured but flowed out powder looks just a pretty, but isn't durable, in my experience. I would make sure your stuff is curing completely.

I bought (or had bought for me) one of those "expensive" 1500w IR lamps for curing powder, but never used it, assuming that it wouldn't cure the powder, so Johno and I built that franken-oven thing, which cures powder beautifully. Now I'll give the lamp a shot, though, seeing the results you've had with those little 500w lights.

Thx!
