DIY powder coating w/o an oven

Prologue:

So about a month ago I was looking at my powder coating options, and I really had not way to access an oven to bake my part. I also wanted to be able to powder coat my frame as well and there is no inexpensive oven that will do that for me. I looked at Eastwood’s site and saw there IR (Infrared) curing system that could solve both of those problems for me, but balls! It was expensive! So a researching I went. I found some guy on a powder coating forum that installs professional systems that said that you could use two standard 500W work lights to create enough heat to cure the powder. It sounded easy enough, and super cheap in comparison. You know what happened next. I forked out the ca$h and sweated bullets about whether it would work.

Set up:

Hot Coat Powder coating gun

2 500W work lights

Powder from a local powder coater

Borrowed airbrushing compressor

Self built stands to hang the parts from and to mount the lights so that they could both be pointed at the part.

Total cost: less then it would have cost me to get my whole ped professionally powder coated.

Technique:

I started on my wrench set. Hang, shoot cure, hang shoot, cure. Hang, shoot cure. I tried out different application techniques and found that while coating you really need to lay the powder on heavy for the final product to come out smooth and glossy, and heavy coat will also cover up some of the minor surface blemishes in the metal. However there is a limit to build up as well, and the only way to learn how much this is is to experiment yourself. Also, remember to swirl the tip of the gun around as you apply as this diffuses the powder better. As for Curing, with the low heat output of the lights, you need to get them very close to the part to get the plastic to "flow out". With in an inch. I also positioned the lights so that they hit opposite sides of the part being coated. You have to move the lights around while curing to make sure that you hit all the areas of the part. And of course, the size and material that you are dealing with will determine how long it takes for the metal to come up to curing temp. Preheating the part is a must. Some metals "out gas" as they heat up and this can cause bubbles under the coat. I learned this the hard way when I tried to reheat a part that had already cured and cooled down. Finally, be mindful of the temperature in the room you are doing you coating. When the temperature dropped at night, I found that I couldn’t even finish a cure. So Midwest, you may have to heat your garage, or get some hotter lights.

So that&#8217;s it. Anything I missed? Let&#8217;s see some other home set ups and results. When it&#8217;s this easy, I expect to see some awesome powder coated peds this spring.

Re: DIY powder coating w/o an oven

Looks like this could be fun to try.. Nice results on those two peices man!

Re: DIY powder coating w/o an oven

Dang. Very nice.

Re: DIY powder coating w/o an oven

Nifty!

A+

Re: DIY powder coating w/o an oven

Nice work; keep us updated on this project, I'm excited to see the final product. That case looks so fancy all painted and inducted...

Re: DIY powder coating w/o an oven

How long did it take to cure?

Re: DIY powder coating w/o an oven

I have heard of people pre heating the object before spraying on the powder to get it to stick. I wonder if a air heat gun would work

Re: DIY powder coating w/o an oven

Clutch cover took about 10 mins. It surprised me at first. Each case half took more like 30-40 mins because I had to reposition the lamps a couple of times to get all of it. Aluminum parts cure faster because they conduct heat better. This can also be a problem because cold drafts can increase your cure time and you have less time to shoot the part because it loses it's preheat temp faster. I will for sure post pics of the frame when I take that on. It's gonna take all day.

What if you put the small parts in an oven instead of under those kinds of "heat" lamps. What temp do you think?

that e50 looks amazing! keep us updated on future projects!

Re: DIY powder coating w/o an oven

you need to let it cure for at least 20 min after cure

also just search craigslist for 2 free ovens

lay one on its back take the door off and gut the other one and place it on top. maxi frames,and magnum frames both fit in the one we have here i will post up some pics of the oven with some how to's later if you want

Re: DIY powder coating w/o an oven

after flow.

fail : (

Re: DIY powder coating w/o an oven

Johnno, I wanna see pics of that franken-oven. It sounds sick!

I chose the work lamp route because of lack of space and that the space I work in is in my neighbors garage (thank god for neighbros).

temp for most powders is 400 F. For my smaller parts, it probs would have been smarter to use a toaster oven, but I wanted to test out my equipment so that I can move up to doing my frame soon.

I bet a heat gun would work for the preheat, but the force of the air blowing over the powder would disturb it after you shoot it.

I've also heard that if you wire the two lamps in series rather then in parallel like they are now, you can get even more heat out ( P=IR and all that).

Kudos for the effort, what I want to know is how you cleaned the parts prior to the powder. I didn't see anything about beadblasting the parts clean.

With parts that small a toaster oven would do the job.

Re: DIY powder coating w/o an oven

Really good work.

Question:

If you lined the back area with aluminum would that help the cure factor?

Re: DIY powder coating w/o an oven

Man, I have one of those outdoor heaters that go ontop of a propane tank, The kind with two giant ceramic disks like this http://www.teksupply.com/farm/supplies/ProductDisplay?mpe_id=13551&catalogId=10053&catalogId=10053&evtype=CpgnClick&intv_id=14501&division=TekSupply&langId=-1&partNumber=pg106297_106297&storeId=10001&ddkey=ClickInfo

I bet that would cure the shit out of some powder. Anybody ever tried it?

Re: DIY powder coating w/o an oven

That is where I am going with this. Got a little more room than Logan. set up a box out of ply, wrap in aluminum foil and put my twin propane heaters on them. Maybe cut a turntable out of ply, so can rotate the piece being coated? Should make like an oven with no door.

Had afriend stop by the other day and she backed into the heater to warm her Bumms. Smelt smoke, there was flames coming off her jacket, she didn't feel a thing. (D)

Re: DIY powder coating w/o an oven

What about just using a couple heat guns? I mean I guess its more labor intensive but it seems like you'd have more control of the heating.

Re: DIY powder coating w/o an oven

nice

so when can i send u my parts to coat

Re: DIY powder coating w/o an oven

What Gun do you have , from where , how much ?

Re: DIY powder coating w/o an oven

I think it is good to get the base metal pretty warm too rather than just flash heat

Re: DIY powder coating w/o an oven

I like the big box idea, I toyed with it myself. It would help in places where it's really cold and a lot of heat is conducting out of the metal, but for this kind of set up, most of your heat energy is transferring into the part via radiation heat and that is limited by your heat source. Those propane heaters would be great. Heat guns wouldn't work for the cure though because they would blow off the powder. They would however, work for the preheat, Which is very crucial as stevew pointed out. The gun I used is the basic Hot Coat gun from Eastwood. Get the gun from them, but don't buy anything else because there way overpriced. There's all sorts of high temp masking tapes that you can buy which are all a ripoff. I used regular masking tape and had no probs whatsoever. This may not be true for oven cures though

Re: DIY powder coating w/o an oven

best post in a while

Re: DIY powder coating w/o an oven

I do paint rehab on wood surfaces (siding, window frames etc)

The best tool for heating up the paint surface without setting anything on fire is an InfraRed heater. http://www.eco-strip.com/ProdStripper.html

But they are 500 bucks So instead of buying one, I made one out of a second-hand InfraRed ceramic heater I got at goodwill. It worked fine. I wonder if it would work for powder coat?

Re: DIY powder coating w/o an oven

Hey, so what did you mask the bolt areas off with? Regular old masking tape work or something for higher temps? Did you have to do anything to help the powder adhere, eg apply a negative charge to it like they say on the eastwood site?

Re: DIY powder coating w/o an oven

that case is great! The paint is sick but case induction? That's one of the sickest mods done to an e-50, ftw. Throw up some info on your build!

Re: DIY powder coating w/o an oven

Nate: "There&#8217;s all sorts of high temp masking tapes that you can buy which are all a ripoff. I used regular masking tape and had no probs whatsoever. This may not be true for oven cures though."

As for the charge, there is a electrostatic charging system that is part of any powder coating gun that you buy. That's all you really need to do to get the powder to stick well.

not it: When I finish the project in March, there will be loads of pics/info. Keep your lemons peeled around town. I'm gonna be tearing up to and around PDX on this guy all spring and summer. Bzz bzz!

Re: DIY powder coating w/o an oven

Wrong, _put my twin propane heaters on them_

don't use an open flame type of heater, will cause the powder to egnite and the mess and fumes are dangerous inside a closed space.

Re: DIY powder coating w/o an oven

God, I wanna coat my freespirit. Do you have to strip all the pre-existing paint or just sand it as you do when rattlecan painting?
