Also interested. Picked up a free oven and am working on the next steps.

Yes, I had a setup before I moved. Eastwood powder gun. Cheap oven, cheap sand blaster. a compressor big enough to blast with was the hard part. Its really important to get the parts clean before coating, thats really the only hard part.
yeah, there's one local for $50... the eastwood gun is like $125.. get some satin black powder to start...
guess some sort of small hanging rack thing to fit in the oven would be smart to build... figure i'll put it right next to my dryer... heck, you could do rims one at a time I suppose...
I want to pull the burners off the top and build a box to hang the parts in. Hook up a shop vac to catch the extra powder and then move parts from the box into the oven. That way the whole setup is just the footprint of the oven. Harbor freight sells guns too, not sure if eastwood is really worth the extra.
i do have concerns about how crazy the powder overspray ends up being.. i like that idea.... put a turntable in it for spinning...
I just painted an ORD crossmember, motor mounts and shock braces. It would have been so much better to have been able to powder coat them. Would have fit in an oven too.

I have the Eastwood gun. Powder over -spray isn't a huge deal.
I built my own oven with some sheet metal and some fire bricks. And a propane burner from an old grill.
I don't have it at my house currently. It's at the farm in storage with some over junk. As Alex said keeping fingerprints off the parts is the most important part.
I think the Eastwood gun is a good unit.

I did something similar except I bought a smoker
Tall enough to do shotgun barrels and wide enough to do 12" wide rims

Obviously part must be clean and free of any residue. Sand blasting gives the best mechanical adhesion, and some parts may resist the powder in a nook or crevice. In that case preheat the part to full temp, then the powder will adhere much better.
Different powders require different temps and duration. Not all powders are UV resistant.

I saw a picture of 2 ovens stacked. Cut the floor out of one and he top off of the other. Put a fabbed metal door on it. I am thinking and old propane tank on end would work.
I have seen plans online for one made out of steel studs, skinned with sheet metal, insulated with rockwool and dual oven elements with a circulating fan. It was about the size of a coat closet, enough that a bumper could hang vertically.

We're setting up a used Blodgett commercial food oven. Just picked one up that is 30x30x30 interior dimensions to see if we want to add it to the shop's line up. If so we're going in on an 8 footer like described above for commercial production. Snagged the oven from FB marketplace.
It's the single stacked unit in the pic. It was a pretty cheap score and a little heavier duty than your standard kitchen oven, 220 single phase.

I have been watching for one of the full height ovens.

I took the skins of two old driers and welded some bent sheetmetal supports in it to place the fire bricks.
Took a old BBQ unit off the curb on a city free junk day. Used the mixing valve. Off that and new cheapy element from a box store. Biggest downfall I had was to not insulating the door. Burned propane like crazy. But it worked. Honestly I was thinking about just getting an old oven for convenience. But I will say that would limit size. Mine is bigger then a oven now. But I currently have a smaller shop now. Hence why I don't have it at my house. So there is that.
If I was using an old oven I would build some sort of stand for it so it it was about chest height and easier to load.

I now know that i will never finish this truck.
Would you mind explaining this? I have a smoker and have found that I suck at smoking. I'd love to repurpose this thing as a powder coat oven
I don't know if if I missed it, but what temperature does powdercoat have to reach to harden and is it a slow warm up to certain temp or is it a consistent temp for so many hours kind of thing?

You preheat the chamber to 400* F and stick it for 30 mins then take it out and let it cool to room temp.
The big oven I used at a friends shop could not be pre heated because you either walked in to hang stuff or rolled it in. Took longer, of course. He did 400* for 25 minutes. I remember different brands of powder had different times needed.
