I've never really been a fan of powdercoating, mainly since you have to give up control of the project. But since I got started on my new pre-unit project I've been giving it a hard look. (Robbie, I know we talked about this!)

Anyway, I figured if I could do it myself it might be worthwhile. A fun project if nothing else. SO here goes: First I got a double oven off of CL; figured I could make the thing one large cavity.



Job one is the teardown



After removing the porcelain-on-steel oven boxes, I cut the facing ends like a "T"



Spread the panels and reinstalled



With the original rock wool packing of course

Then the upper



And start screwing the whole thing together



The door was intimidating but I got lucky. I found some surplus paintbooth sections that were formed sheet metal 24" wide; perfect for what I wanted. All I had to do was bolt in some unistrut for the top and bottom ends. Also, one in the middle for good measure and installed the window from the original oven.



There was a gap at the back wall to be filled, but there was plenty of sheet metal left over from the oven teardown



Then I hung the door.



SO the last issues were to latch and seal the door. Off to Home Depot for some fiberglass rope- they sell this to repair wood-burning stove doors. I started with these shallow channels that are intended for hanging shelf brackets



I put a piece of safety wire every few inches and screwed it down to the oven. Then I twisted the wires, securing the rope to the channel.





Almost ready to go! Last job was to insulate and skin the outside of the door



And build the latch (made from a welding hammer)

I looked at a lot of the lower-end powder guns. They run from Harbor Freights $60 gun to many thousands of dollars, but I finally settled on the Caswell gun. $140, and it's adjustable from 30-50 kilovolts.



My "spraybooth" is a rolling clothes rack from the attic and a dropcloth. I screwed a wire shelf to the top to give me places to hang the parts.



50 kilovolts in action!



My test piece was this engine mount; pretty manky but I carefully grit-blasted, then sanded it to get it somewhat smooth.



After coating, it looks furry as if flocked; which it has been I suppose.



When the part gets up to temp, the powder flows out and becomes shiny



Then you set the timer for 10 mins and out it comes! Ready to use as soon as it cools.

I'm very pleased with the results. There's hardly any cleanup; no "overspray". You just sweep up the powder that doesnt stick but there was hardly any.

Powder is about $10 a pound, which they claim will cover 70 sqft. Seems about right, I bought 2 pounds and it looks like more than a quart of paint.

I had the Casswell setup myself. I used a single oven, and was able to do alot of stuff, basically anything that would fit in the oven. With the extra capacity of your oven, you can do much more.

It's big enough to take my pre-unit swingarm frame...somewhere around 20x20x40.

Costs:

$100 oven
$140 gun
$15 in hardware (hinges, channel, rope)
$6 chipping hammer (a luxury item, but its handy since you can run the door without a glove)

$261 total

Doing things yourself is cool. Savings tons of money and having something pretty to look at as a result is even cooler.

Not unusual to find free ovens on CL. As long as you can pick them up. Doubles like this would be more rare.
I saw some free ones and some as low as $20, but I really wanted the flexibility of the large cavity.

It probably would have made more sense to just use free oven and then just throw it away but I do love a project. And it'll do my frame.

Good deal. Like the setup. I've always envisioned taking two stand alones and mating them up side by side.

I bought my kit from eastwood and an oven was free on craigslist (the range didn't work)of course I had to pick it up,I mounted it on a 3ft high frame with wheels when it's not in use I move it under the deck in the backyard.
as Tony the tourch said a minium of $35.00 at the powder coater and my powder coater won't do small pieces like spacers and bolts,whats nice is you can put everything off the motorcycle in a single oven but the frame.
I really like the idea of the double oven.
