Let's try economy powder coating at home

[spoot]

Are you sure you're using the right scotch for this application? Perhaps it requires gin.

I'm going to make sure I try every possible combination to refine my technique, I do it in the name of science!

I'm doing science now!   Horray for whiskey!

I say forget the power coating and make a kick ass footlong sub toaster!

Toaster pron.  That's weird.  Leave it up to an Aussie/American/UK-ian to come up with that.  You feriners are weird!...and illegal in 37 states!

There's Aussie in this fella?  Where?

You can tell a man designed this, its got diamond plate



This is by far the most dangerous thing I have ever made. Still have to come up with something for that middle door but the chamber now measures 26” wide by 12” high by 10” deep.

Have you ever seen something so beautiful before? I think not.

They're making fun if my mashed up accent. Spent a year or do in Sydney as well as many other places so I'm verbally mutated

For some reason, I'm picturing these posts by the unconventional conventionists in this Franken-. . .toaster thread.

Griff: Oh, I just love success!
Poster 1: It's a credit to your genius, Master.
Griff: Yes!
Poster 2: A triumph of your will.
Griff: Yes!
Poster 3: It's OK!
Griff: OK? OK? I think we can do better than that! . . .

I'm naming him 'The Two-Headed Toast'

I think you should post it over on KLOV as your latest WIP cab and seek honest opinions...confuse the ---fudgesicle--- out of them

Just keep the fire extinguisher nearby and teach the kids how to dial 9-1-1.

Wow, serious toaster business in here.

[griffindodd]

I think I may sell this design to NASA, or Apple



Made the double walled insulated door out of the drip tray and a left over piece if the body. So far everything has come from the ovens except the door handle and the one piece if diamond plate

Nice work on the initial test piece!  Looks way better than I thought it would out of that little oven with the element so closeby.   


I'm concerned about that huge toaster setup.  Not so much about the heat but about the current.  There are about a million places where that housing could be shorted and you're only going to find out when you wake up looking at the ceiling.  We're not talking electronics DC here.  That's straight up high current AC.

Consider using a real oven here or at least moving those guts into some intact housing that isn't hacked up on every surface.  A file cabinet comes to mind.

[griffindodd]

Aye Chad you are totally right, this thing really is a safety nightmare, although I did make sure that all wires and terminals were shielded with high temp cord and clear of any sharp edges. All I really want to see here is if I can get a space this large to hold temp with just the 1500w element, if I can successfully cook a few larger pieces like my bezel/glass rail then we've achieved the goal and proven that a standard toaster oven has enough power to powder coat moderate sized pieces at home.

The filing cabinet is absolutely a great candidate for this kind of thing, but to be honest, as long as I can cook my coin doors and lockdown rails for the Paperboy cab I'll be happy to trash this health hazard and wait for my real oven to be built. For teh cost of just getting the powder coating done at a shop, I bought a gun and learned enough to be dangerous while being able to point at my cab and say to my friends 'Oh yeah, yeah so I did all my own powder coating...what? yeah I do that stuff...yeah I do all my own stunts' 

[ChadTower]

Good. 

I still say propane is the better way to go in the long run.  With the right valve setup you can get temps just as stable as with electric without the risk of electrocution.  I can dial my propane meat smoker in within ten degrees anywhere from 125 to 400.  The only reason 400 is the upper limit is because I don't think my cabinet would stand up to more than that for extended heating times (plus who would want MEAT done that high).

Yeah I've been looking at the propane and it sure looks to be the right approach for a larger oven. I still haven't heard from my buddy since I gave him those plans, so it's up in the air as to whether he can get it banged out for free by the fabrication shop, fingers crossed. But, if he does pull it off then I'm thinking of using a Mr. Heater 35,000 BTU constant electric ignition with a heat control/valve unit.

How do you control the temp on your smoker?

[ChadTower]

Most propane cookers will come with a grill type valve that will get you around 30 degrees of accuracy if you have a thermometer in the cabinet.  The limitation is that it won't give you all that much of a temp range.  They're designed to give you the fairly narrow range of temps at which you would cook on a grill.  You need more range than that for powdercoating.  I also need more control than that for my smoker because dehydrating can go as low as 125.  The lowest my smoker could keep stable was 175.

What I did was replace the hose/regulator assembly with with one that has an inline needle valve after the regulator.
This gives me the ability to keep the OEM burner fully open and control the propane far more finely.  The PSI on the regulator is your choice.  I think I put 12psi in mine and the needle valve allows me to open that puppy WAY up if I want.  The control on the needle valve is the key.  It really lets you fine tune the flame down to within about 10 degrees.  I like to use a remote meat thermometer inside the cabinet to get good accurate readings.  Once you dial that sucker in to the temp you want, leave it running about 10 mins to make sure it's stable, and it will only change if the environment does (rain, major wind, etc).

Here are a couple of pics I took when I was modding my smoker.
