That’s awesome! I started powder coating just hobby stuff and parts to a CJ5 I built. I needed a bigger oven, so I built one out of old highway signs (throw always, I didn’t take signs down) and an old oven a friend gave me. Then I needed a longer one so I used an old school locker and ended up with three ovens with less than $200 in them. I powder coated parts to the friend who gave me the signs and oven for his 69’ Cameo he shows. Word got around and now I make a few hundred bucks a month powder coating odds and ends for people. It’s my play money, but what the hell. I like your build, great video!
I built an oven out of a metal trash can and a 110 single burner element. It has a bbq temp gauge in the lid, one big rack to put stuff on and hooks in the underside of the lid to hang stuff from. It works really well. $35 total investment in the oven and I use a $75 dollar harbor freight powder coat gun.
Man, that is amazing ! You've given me hope to build my own oven now cos I've got a tonne of stuff I can powder coat rather than pay the expensive rates they charge these days and avoid the rubbish rattle can finish. Powder coating is THE best and most durable finish you can have on automotive stuff as well as other industrial bits. I also have a BMX frame I'd love to do myself too !
Very nice setup man!! I've been using a standard oven for a few years. The limits on what I can fit really sucks. I've always thought about building one using the old ovens parts. This just sealed the deal for me. Awesome job man!
Congratulations on another successful project. It's really rewarding constructing something yourself that works just as well as a commercial unit, but costs a fraction of the price.
Thanks you for this video I’ve been very interested in making my own powder coating oven for my channel keep up the great work can’t wait to see it all done
Dave, I built my own powder coating oven many years ago. sheet metal welded frame, angle iron frame for the door to seal against. household oven element and controls. Rockwool insulation from McMaster Carr. Mine is 3'X3'X2' love it! wheels, suspension parts, crossmembers, but not FC
Nice job man! I live in the netherlands and have a tiny shed where I basically plan on doing the same stuff! I already got a nice compressor, a powdercoating set-up and a used small kitchen oven. I still have to buy a sandblasting cabinet and then I can start powdercoating valvecovers and control arms for my friends! I also tried messing with derusting by submerging metal objects in vinegar but the moment I take it out it instanly rusts again. Have to figure something out for that too. I wish I had as much space as you, I’d definitely build my own oven too!
Did you just use the normal convection fan in the regular spot in the middle off the oven? I'm using a doner convection oven but im worried about the convection fan blowing powder off but high temp blowers are more than I want to spend
i saw my soninlaw build one out of an old freezer using electric oven controls after removing the freezer compressor and other non essential stuff. seemed to work well for him.
Thanks for the inspiration to get off MY butt and finish my powder coating oven! I've been procrastinating because mostly I am unsure of the electrical works. I'm good with my hands, welding, mechanics building but wiring just baffles me and the older I get the harder it is to see 🤪. However, on the temperature side of your build, if you haven't done so already, my research has a solution. Use a ceiling fan. Get smaller blades, mounted in the bottom, motor on the outside, fan on the inside. Ceiling fans run slowly forever, circulating the air giving you perfect even temperature. Simple, one tiny hole through the box with a small fan! Thanks again, Tim
Suggestion: Add a SLIDE to your center mount where you hang your parts in the oven. That way you can attach your powdered part to the hook faster and more easily. You wont be losing as much heat from the oven since you will be shutting the door faster. Just my $.02
Your oven definitely looks better then mine haha I used steel stud and mines a 3' cube. I started with my elements just like you had on the top and bottom but ended up changing them and mounted one on each side at the buttom. As well as I put a convection fan in. The regulation from the top to buttom was like 70° is some spots. With the elements on the sides and a fan in there the relation is about 10°
came out great dave. if i could suggest one thing it would be to put a fan inside. That way all the oven is the same temp plus parts will come out more uniformed.
Awesome build! Looks like the perfect size. If you want to bring it to the next level on the cheap, replace the oven controller with a Temperature PID, solid state relay(SSR) and temperature probe. Also pick up a convection fan from an old oven to circulate the air and your temps will be more consistent throughout. The PID setup will keep your temps wayyyy more accurate than the oven controller, and you can pick up the packages that include the PID, SSR, and temp probe for a lot less than you think. 8-) Keep up the good work man!
Very nice build David, I've been thinking of using the same idea but making a taller box, big enough to get a motorcycle frame in. I might need to find an old double oven just to get the required heat. Thoughts?
You should put a cage/mesh around the elements. Also the oven control will very the temp it won’t hold them at the highest temp. You need to ditch the fancy electric control and just have a simple switch set up for heat. Most parts will be baked at the same temp so really on need low and high (this can be done by wiring the elements in series or parallel)
Good work Dave. I been wanting to build a similar oven for cerakoting gun parts and knives. Possibly powder coat on down the line. What kinda insulation did you use?
Sweet video.... I modified a regular oven to hold a 24” part ..... currently looking for another free curbside oven so I can stack em and weld em together! 🤙🏼🤙🏼
lol i started with an oven that i made a box that sits on the open oven door and would give you 2x the space! but look into pid temp controllers when you go to upgrade your oven. there cheap and work good at holding the temp
Cool oven, building one day..I'll probably mount a small fan outside the oven with the blades on inside to distribut the heat some. (Making sure I don't blow the powder paint off the part of course.).
Sweet oven build! Did you do anything special to the wiring like wire both elements to come on at once instead of only 1 at a time for bake and broil like factory??? It would get to temp fast! But not sure if you would need to wire it for more voltage?
Made a oven using an office cabinet measuring 1100mm x 1000 and used 50mm steel stud wall framing and rockwool insulation. Picked up a free home oven for 1 element, 2 lights. I build a control panel using a PID and SSD relays, amp meters for 2 elements and purchased 1 more element. Works a treat. You did a great job of yours but use a PID to control the temp as home oven temp controls are not accurate.
You really need a PID controller to help you maintain a constant controlled temperature. I built a similar powder coating oven last year the PID co roller is a game changer.
I’ve watched this three times now. I built one using metal studs and it just wasn’t solid enough. I’ll be going to pickup tubing today and get my frame welded up. Maybe if you get bored you could drop a video explaining the actual wiring of this oven. That would be awesome.
Excellent job! But you need to ditch the oven control and use something like an AGPtEK Dual Display Digital Programmable Temperature Control TA4-SSR, Amazon has it for about $28, it has over temp alarms and built in sold state relays. Chuck full of features
The recommended maximum temperature for long-term exposure of galvanized steel is 392°F (200°C). At higher temperatures, the zinc coating on the steel can melt and vaporize, releasing toxic zinc oxide fumes. Zinc oxide fumes can be invisible and can have harmful health effects if inhaled in large quantities or over a long period of time. Symptoms of zinc poisoning can include: Yellowish fumes, Zinc oxide particulates, and Lead oxide
It looks like you need a draft control area when applying the coating... So use a fan behind some filters and spray in front of the filters. Other than that it looks great to me.
looks better than the oven i built. I went cheap with two free ovens, just cut the top of one, bottom of the other stacked and welded. i can bake on the lower unit and broil on the top heats up in 5 min
Nice build, one suggestion Instead of that cheap Insulation you put on that oven I would go out and get HVAC 2" ductboard and some aluminum tape to increase the efficiency.
Also to make it stick to the side of the Oven use 3M spray glue. Spray both the oven and the duct board Let it stand for about 20 to 30 seconds to tack up and then place the duck board onto the sheet metal
Thanks for showing that. I always wanted to build one, but they take up so much room, and I do not need to use them often enough to justify the space loss. But, you are correct in that they take so long to get done as powder coaters are always booked out, and it is never convenient to wait as time is precious and scarice too. Now, if i build a new shop, then maybe... (grin) "Honey, I need to build a new shop for my powder coating machine" -Because, why would i build a small building when I may as well build a bigger building I can use for other things too!
Oh this kind of comment drives professionals nuts . I have a beautiful wood shop "im a cabinet maker" and when people Say shit like " oh the things Incould build" I think "the things you could fuck up"
so cool. question -> can you hypothetically make a giant powder coating oven by using the "guts" of several ovens (and wiring them to one single control panel)?
Dave, I don't see the links you mentioned. Can you give me an idea of the size and/or dimensions? I've been thinking of doing this very same thing to coat my new tubing bender. I bought the Rogue Fab M600 (some assembly required) to save money. You have to weld it up and paint or have it coated. It's a little too big for a standard size oven as most car parts would be. I've also got a refabricated trans cross member that I would have liked to powder coat also. Mark
Does your shop have a ceiling mount fine hood? I saw what looked like a tray ceiling then upon closer look it appears to be a smoke/fume hood. If yes, did you design and fabricate it yourself. Also, thanks for the video. Been wanting to do the same thing. Can’t believe what they charge for a box with elements. I guess UL listing is creating a chunk of the costs.
Great build. Only thing I dont like about it is the top element.. Id keep the thermo coupler towards the top maybe 3 or 4 inches from the top like that but move the top element to a dual bottom element. Could help with the inconsistent tempratures youd get off it that top element so close to the thermo coupler I would think it would kick it out too easily. Other than that good build thank you.
