I have now received 5 quotes for powdercoating a roof rack.  None of them were under $1300, and some were closer to $4000.

I can paint it, but I'm a wee bit concerned that (being a roof rack) paint won't be very durable.

If I break it down to component pieces, the longest piece is 5'6".  That won't fit in any normal oven.

Enable me.  Dumb ideas on how to make a 6' long powdercoating oven?

In GRM tradition I'm going to ignore your question and just state that powdercoating your hootus is a bad idea.

Craigslist oven, dismantle, build a box to hold your stuff.

Use this to line said box and you can get away with non-metal stuff for box sides.

Find a closed down Quizno's and spray powder on as part goes into one end of the sandwich oven.  Retrofit servo control to dial in perfect speed to achieve cure you need?  

 

You did say dumb ideas....

In reply to travellering :

That's actually what I was thinking of suggesting. 

Pci auctions will probably have a pizza conveyor soon if there isn't one up now.

An open space, a bunch of bricks, a pipe which a bunch of holes in it, a propane tank.... winning.

Two ovens. Remove doors. Put item in one and slide the other face to face.

I'm loving these ideas.  Conveyor would work if it were only coated on one side.

What's my target temp?  Edit:  Nevermind.  I googled it

Could you not just hang them, powdercoat them and use heat lamps to heat them up?? The closer the better. At 130 each buy a few of them. You can then use them in your shop to cure 2 part paint

I've been in a walk in size electronic powder coat oven. The heating elements didn't look like much more than baseboard heaters with all of the shrouds removed.  I wonder how hot some heating elements you could get at home depot could get?  Make a lil brick tunnel long enough for the parts and jam a few heating elements in it?

Know anybody with a big boy smoker? 200+ gallon should be big enough to get the piece in, basically a giant wood fired oven.

Curtis, I know that you will want to use only the most socially responsible and carbon neutral option.   A solar oven is clearly the answer!  Or a bunch of them lined up end to end.

32 MAP torches under the item with a wire and aluminum foil hood. Profit.

Seriously when I looked into it as a side gig the IR lights on a stand were the way to go. Kitchen oven for 1 wheel at a time too.

Get up on the roof and hang it down your chimney, then start a fire?

Step1: POR-15

Step2: Rustoleum Professional Enamel

Step3: World domination

Por15 is super tough and easy to apply with a brush. It converts rust, stops the development of more, and is bombproof. Nothing fancy required, just be sure to do all the prep according to the instructions. Its only kryptonite is that it breaks down under UV rays. Hence the Rostoleum enamel - a good coat (or maybe 2) will block the rays and keep the rack protected.

It's also really tempting to use the overhead radiant heater in the shop.  46 feet of hot tubing.  Just not keen on using what little money we have at work on a gas-fired personal project.

That would be great, except it's aluminum

Find a coal-rolling brodozer and stick it down one of their oversize exhaust pipes? Tell the driver that your roof rack is a new anti-Prius device that is activated by the 5G wi-fi signals from the hybrid battery pack and will increase their visible emissions by 50%.

Agreed.  All I need is a big enough box and a way to make it 400 degrees.

I actually built an oven that was about 7' tall for a similar reason. It cost a few hundred dollars and followed these plans for the most part https://www.powdercoatguide.com/2014/09/how-to-build-powder-coating-oven.html?m=1

Oh yeah, 'specially that oven bit at the end. 

Curtis, media blasted, a quality primer and good paint lasts how long?  If it were me, I would go for paint and touch it up as necessary or just do it all again in 5 years.  Powder coat doesn't stand up to flying pebbles any better than paint.

If the parts are long and narrow, get a single burner electric burner from goodwill. Go to home depot and get some of the pipe you'd use to make a chimney for a wood-burning stove, Put a hole through both sides near the top you will use to hang your part. Put a cap on the top. Jab a simple BBQ thermometer through the pipe aroudn where the part will be to watch the temp. Now you have a long and narrow oven for powder coating long narrow parts.

That's how I did things in the past. Works great.

Oops, you said bad ideas only.
