I like it............. I'm behind the curve on powder coating.. Could you tell me what kinds of Temps are required to powder coat? My neighbor set up an oven with a 48" x 48" stainless box and insulated it with oven foil and layers of duct liner glass.. But he used elements, thermostat and controls from a 220 range/oven. So I'm thinking he's running at 500f or less. Does that do it, or are there various powder coatings with differing specs?

I ask thinking maybe I'm not the only one who doesn't know.. Hopefully
It depends somewhat on the powder. Some cure lower, some cure higher but most of them are in the range of 375 - 400 degrees, The important part is that it is PART METAL TEMPERATURE not oven temp. So you start timing your cure time when the part hits 400 not when you put it in the oven. For large heavy parts like wheels, intakes, it can take up to 45 minutes for the part to hit the right PMT so you're looking at potentially an hour at 400 degrees for a cure.

Here's some of my work

Coal bucket in Green Vein



Valve covers for a friend. Blasted Aluminum powder over mirror yellow



Edlebrock Intake and fuel rails off the same car.

Clear on the intake, Mirror yellow on the rails



LS Truck Manifolds in Cast Iron Ceramic



DSM Manifold, Satin Black and Red Wagon



My Own Intake and fuel rails. Everything here is powdered

A conventional electric range should be plenty good for most hobby powdercoating. I never run mine over 450* and as mentioned above, most things are done in the 400-425* range. And aminga is spot on regarding PART temperature, not oven temperature. Makes an infrared thermometer almost mandatory for determining the part temp. and the timing for the entire process. After a while, you can pretty well determine the time sequence based on flow-out of the powder. But early on use your thermometer.

After a hard lesson on my new and improved T-type wheel project. I always use the IR thermometer. First time I did this I had an hour of blasting and 3-4 hours of polishing in each wheel. THe cure was 20 minutes after flowout. The first time it got cold the powder cracked and came off the polished parts.

Not to get too far off topic but I've been using some of the newer Air dry ceramics. No curing. Just spray it on with an airbrush and let it dry. You have to be a little careful on first start/run with the temps but it's easy as pie

Do they cure as the part heats up during operation?

Yes. You just can't go nuts with the EGT's before it cures. Idle it for 30 minute and it will be fine.

Here's a set of ford longtubes in Satin black

Congrats, that looks like a class act.
Can you post details & dimensions for us DIY's that can't afford to buy one, please?

Thanks.

I build my abrasive blasting cabinet and it worked out pretty damn well. You can see the build on my blog at www.smecca.com

a few days ago i broke out my homemade buffer (i haven't been in the garage really for a couple years) i had forgotten how satisfying buffing metal can be, it's great when you've been working different pads and compounds and all of a sudden you start to see the unmistakable signs of success. i highly recommend it.
so then i saw this thread and had to send a pic since friends have laughed when i told them about it and say "no way" when i show it to them and then they nod and rub their chins when i demonstrate it.
it's especially funny since it's basically made from an exercise walker (treadmill?) that was out on the street for bulk trash pickup and an old floor jack, i actually grabbed the treadmill for the metal frame which i used to make a tiny trailer for a guy who paid me 200 bucks for it .
the rollers have a 3/4 shaft and a bearing at each end, and was even fine threaded at one end, readily available chucks will screw right as does most everything else.... plus, since there were two rollers, i have a spare which i thought i'd need, but still haven't, the floor jack i just chopped up and welded for the stand. the shaft is basically unaltered except mounted and gusseted with a pulley on one end, (you can use different size pulleys for different speeds, i also used to use it as a bench grinder before i bought one) the motor is off my table saw which is what i clamp the buffer to when i use it. i thought about a third pulley so i didn't have to swap it out, but, it's no big deal, 4 bolts.
while i was out there taking a pic, i figured i'd send one of my version of an "upright" compressor too. it's just a couple small tanks that had been thrown away hooked together with a hose and check valve (which was already in the tank) , the pump is a harbor freight special, 100 bucks on sale for their big one, 5 hp or whatever, the motor is the key, its a commercial unit from an out of business garage a friend gave me, all combined, it kind of kicks ***.
