i have a question and i dont know where to ask it.

i want to powder coat my parts, but, i dont have access to an oven.

has anyone tried powder coating with halogen lamps? i have a few 500 watt halogen lamps so i was thinking put 6 together and that will give good heat the the powder coat.

what do you guys think?

thanks for your help !

The part itself needs to get up to 375-400F for 15 to 20 minutes depending on the powder. I don't think the lights would get you the temperature you need but you could try it without powder first. I have a 4'x4'x8' oven for bigger stuff or lots of parts at one time but for small stuff I use an old oven I pulled out of one of my rental properties. If you have a power source try to find a junk oven. The only downside of the regular ovens is that they do not hold temperatures very accurately.

How big are the parts you want to do?

i want to do crossmembers, engine mounts, master cylinders, brake cylinders, etc.etc.

I would say go with a house oven and get a better controller for it from Auberin. Some guys will figure out a way to mate two ovens together for slightly bigger parts or figure out a way to add a little more room with some metal and insulation and place the 'addition' on the open door of the oven. Then the trick is to figure out how to hang the parts while they cure.

I can give you some links for powder in small amounts if you can't get commercial grade stuff where you are.

here in japan we have these little toaster type ovens, it has a timer to 20 minutes and i think will work great for small parts.

That will work for really small stuff. Figure out how you can hang stuff to keep things away from the heating elements. Stuff like a brake caliper can take 40-50 minutes in a 400F oven to get to temp, then you start the curing time clock.

Get yourself an infrared temp reader, it will save you a lot of trouble with under cures.

If you really get interested in doing misc car parts it isn't that hard to build a small oven for a couple hundred dollars. I can point you to all the parts you need including heating elements that a lot of guys use that come out of regular size ovens that run about $25-30.

Here is the thread from my oven build.

what about building a room out of cement blocks, and putting 4 x 2000w infrared heating lamps inside? wouldnt this get the same benefit? regards. david...

iam going to be straight with you i do powder coating for my self a people that can convice me to do it for money now that being said you 2000 will not be enough to cure it evenly you might get a spot but the rest will come out like **** i know this from doing it. now that bing said i will provide you with what you need to know. first the apropriate lights that are powerful enough to do it are these http://www.eastwood.com/hotcoat-powd...ing-lamps.html now this is not cost effective enless you have a shop and are making a living off it now a boothhttp://www.eastwood.com/hotcoat-powd...ng/booths.html will for powder coating is unnecessary enless once agian you have a shop a pice of drop cloth will do the same job and a kitchen oven will work fine if you put an accurate thermometer in side that you can see from the outside ohh and purpose mad ovens are not cheap http://www.eastwood.com/hotcoat-powd...ing/ovens.html
but that being said the gun is a lot cheaper for a very good one http://www.eastwood.com/hotcoat-powd...coat-guns.html
and to make it better you can get that with every thing you need to get started even powder and the good thing is you can catch what you dont use in a drop cloth and re use it and the powder is cheaper then paint and you use less of it. so just for your own sake use a regular oven cuz doing it with the heat lamps is really really a pain. and just to give you some back ground i use powder coating at work coating parts for f-18 jet fighters and i have all these tools at my disposal and it such a pain using the light (and it takes several more hours to do) that my command bought an oven big enough to fit a suburban in too its that much of a pain that they said **** it and got a million dollar oven ill post pics some time.

Toaster ovens don't tend to produce even and accurate heat unless your using nicer one.

Spending money on the toaster oven or halogen lamps would be a bit of a waste unless you just had them lying around already.

I would say just go to the local appliance repair shop or check out craigslist and see if they have an old but working house oven or commercial oven you could buy on the cheap that's what i did and works great.

Just check with thermometer so you know if the temp is off and by how much.

You should see some of the double decker ovens guys build out of two home ovens. I've also seen guys find a way to put two face to face with no doors. Double your fun for almost no money.

I'm not sure they have craig's list in Japan though.

it's not like old ovens are hard to come by... don't they have a craigslist or an oven junkyard in japan somewhere where they retire ovens that have more than 30k miles on them?

dr50376272

in japan, everything over 3 years old except kids are sent to africa as scrap.

kevk

then find one before it goes to Africa and just deal its not hard and if there bing sold as scarp then it should be easy and cheap and if you cant get over this hurdle you should just pay some one to do it.

Don't use lights, it won't come out right. Like some have said, get a used electric oven from CL. Here is a front cover I did today. I have the Eastwood hobby dual voltage gun and use an old house oven. The other piece of advice, make sure the parts are clean of any dirt, oil, old paint, etc. I out gas any part that has been in contact with oil. After blasting the part the first time, put in oven for at least 15 minutes longer then the cure time and about 25 degrees higher. I then blast the part again and blow down with clean dry air.

This is an air pump that I polished then shot with super gloss clear powder.

Finished the rebuild of my engine with the help of Trochoid. I think it came out nice. I'll be working on a complete build thread in a couple of weeks. I'm taking the entire week of Thanksgiving off to put everything together. Irons are powder coated in black chrome and the aluminum parts in silver sparkle.

How long did it take to get those irons up to temp? They look great.
