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.
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!
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
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
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
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.
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 !
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.
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
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!
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)
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
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
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
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.
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
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.
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.
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°
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!
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"
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!
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
I like it. A couple of thoughts however. First, consider the way you made the frame. You have large areas that are un-insulated, and the frame provides a direct thermal bridge sucking heat out of the oven. So not only are you paying for a lot more electricity than you need, but you are pumping that heat into your shop. Perhaps OK in winter but in summer that's not good. Now consider an alternative design where your frame is on the outside and you fab a box on the inside. Inside this box you line it with a rigid ceramic insulating material on 5 sides. Now fab an inner box and slide it in. You will have no thermal bridging. Make the inside box with a flange to effect a seal with the door. Next, do you really need a window? Windows are big thermal holes where you loose heat you want to keep inside. In powder coating, having a window allows you to watch paint dry. I don't really think there are many times you actually need to watch the process. On your current oven, you are stuffing the electronics in a place that is going to get hot. This is not a good thing as it doesn't take much heat to cook microprocessors. Wires. Any wire that is going to get exposed to heat needs to have high temp insulation. It appears from the video you used regular wire with plastic insulation, you might have problem. When you suggested that an analog controller was some how inferior to the digital, this caused a big cringe. On an analog design very little can fail, on the digital lots of things can, and do, go wrong. If you only are going to do powder coating, the digital whizz bang can actually be a disadvantage as the ones I have seen require you to reset the temp each time you turn it on. what happens if the controller works but, the display goes on the fritz? On an analog controller, when you hit the on switch, the oven goes right back to the last setting and you are in business. As others have mentioned, a PID controller is the way to go, you will get a much tighter control of your temp. They often can be found used on e-bay or there are a bunch of cheap Chinese ones new for less than $20.
just a tip put a clear coat on it last a lot longer and shines better too also check out pid temp controllers there pretty cheap and work great i also made 2 racks that slide on angle iron right at the top so you can load all the parts to the racks and swap as you shoot the powder
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.
I know nothing about powdercoating ovens, but I do know that your standard cooking oven doesn't hold a constant temperature, not by a long shot. So, if you were seeing a lot of variance in the probes, don't worry about it too much. Oven temps aren't really meant to be all that accurate (they don't need to be). Hopefully that's not a problem for your use case (doesn't seem to be--that part looks like it came out well). Here's a link that talks about it. www.thekitchn.com/why-you-should-stop-worrying-about-your-oven-temperature-175602
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?
When it is running and at temperature, how hot is the outside? Can you lay your hand on it and not get burnt or too hot to keep your hand there? If you don't have any outside issues, then you did good...
Question I’m building something similar to your oven and I have a old home oven But how did you wire your heating elements, did you wire another element parallel to the existing heating element? Or
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.
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!
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?
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)?
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?
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.).
You should just replace the oven controls with a cheap PID controller. You could get way more consistent temps, and not have to worry about temperature readout.
How much Watts you put in that oven? Mine is like 1m x 1m x1m Outside and 90x90x90 inside. And i bought 2x 2650Watts heat elements. I dont know if this is enough lol 🤣
Great build, but I have a few questions. Excuse me if they aren't well articulated, but I'm new to powder coating. Would it have been easier to use an upright freezer and modifying it? Did you consider a high temperature fan to circulate the air or is it necessary? Thanks in advance.
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
I noticed you use regular insulation. I understand that melts at a very low temperature, well under 365°F used for most glazes. I got some fire rock (rockwool) for my oven that I haven’t built yet. That cost $50 for a small amount, considerably more than regular insulation. I have a lot of regular insulation and would like to use that if I can. What was your experience with this? I got the prior information off of Owens Corning literature, but I did another search and a site tells me that regular insulation will go to 1000°F. Now I’m more confused! 🤗
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.
I think you said in the video that you bought an oven in which you use the heating elements in the new powder coat oven that you made. Is the new oven that you made run on 110 or 220 V?
Good idea Terry, I was going to the same with an old one my parents have. Make sure you have the refrigerant captured; there is bound to be places around you that will do it for free (that already recycle fridges) or for a low price. I think I'm going to turn the one I have into a worm farm (ha ha!) and build a larger homemade oven to be able to do much larger pieces for an experimental airplane I've just started.
@@michaelz6870 the ex-wife was going to give me one but I didn't have room for it so it went to scrap. after I get my garage built whenever they give me the permit that'll be one of the projects that I will do
what kind of fiberglass insulation are you using, and doesn't it matter? I want to try to build one myself and be able to learn as well how to powder coat.
I recommend you to pre heat your parts after you de greace them and just coat them directly out of the oven while still hot. then just toss them back in.
I was going to make my own powder coating oven and use a steel cabinet 6hx4wx2d. I’m just not sure how much power is required to heat up an oven element. I know there 220 but could you run one of a 12v each or even off its own 110. How power did you need for those two elements?
Do a big plate of cookies, no joke, see how even that oven heats, you would be surprised how most ovens don't heat evenly everywhere, you might find you don't have enough elements.

I like how you just come up and say: "I'm gonna build this", and frickin get it done! ...You're a real inspiration Dave!
have a look at the workshop set up and equipment. the every day do it yourselfer dosnt have that set up.
torkan2 thats the case with most of these DIYer channels.
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
I built one similar and i used a convection oven fan to get even heating. It made a big difference. FYI
Excellent idea Paul I wanted to build one about the same with that he built but twice as high
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

Are there specific heating elements you need to run the PID controller?
@@cskiles It makes no difference. The PID controller just turns the heating elements on and off to keep a consistent temp.
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.

Satveer Degun er, no. Really bad idea.
If you weld some standoffs and then mount the oven racks to it, you have infinite mounting points for hanging stuff!

Nice! I've been needing to do this myself. I like your insulating solution too. Your oven will basically pay for itself after a few uses anyways.

Isn’t the galvanized steel hazardous when heated to hot ?
Might pick up a stove first but need to find out how to sit everything in without messing up the coat?
And what do you stop the old paint off.
Hopping on this diy powder coating bandwagon and giving my thanks Dave. Much appreciated.
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.
Very cool.. I'm just curious what type of metal the red sheet is? Painted or pre painted from your local yard? Or maybe recycled from something else?

Totally agree. Possibly one out of a convection oven. Even heating throughout.
Nice job Dave. I've been watching videos on this subject all morning so imagine my surprise finding out you had a how to video on the subject.
straight to the point on making a decent oven... best video yet.!
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 agree. It will probably be a heck of a lot more reliable than the household controler.
Would’ve been better to mount the heating element to bottom as opposed to top? Because heat rises and it’ll be easier to mount projects for baking?
Your oven definitely looks better then mine haha I used steel stud and mines a 3' cube.

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
you thought about putting an internal fan in it? move the air around?
I like it. A couple of thoughts however.
First, consider the way you made the frame. You have large areas that are un-insulated, and the frame provides a direct thermal bridge sucking heat out of the oven. So not only are you paying for a lot more electricity than you need, but you are pumping that heat into your shop. Perhaps OK in winter but in summer that's not good.
Now consider an alternative design where your frame is on the outside and you fab a box on the inside. Inside this box you line it with a rigid ceramic insulating material on 5 sides.
Now fab an inner box and slide it in. You will have no thermal bridging. Make the inside box with a flange to effect a seal with the door.
Next, do you really need a window? Windows are big thermal holes where you loose heat you want to keep inside. In powder coating, having a window allows you to watch paint dry. I don't really think there are many times you actually need to watch the process.
On your current oven, you are stuffing the electronics in a place that is going to get hot. This is not a good thing as it doesn't take much heat to cook microprocessors.
Wires. Any wire that is going to get exposed to heat needs to have high temp insulation. It appears from the video you used regular wire with plastic insulation, you might have problem.
When you suggested that an analog controller was some how inferior to the digital, this caused a big cringe. On an analog design very little can fail, on the digital lots of things can, and do, go wrong. If you only are going to do powder coating, the digital whizz bang can actually be a disadvantage as the ones I have seen require you to reset the temp each time you turn it on. what happens if the controller works but, the display goes on the fritz? On an analog controller, when you hit the on switch, the oven goes right back to the last setting and you are in business.
As others have mentioned, a PID controller is the way to go, you will get a much tighter control of your temp. They often can be found used on e-bay or there are a bunch of cheap Chinese ones new for less than $20.
I don't think anyone read past the first sentence.
just a tip put a clear coat on it last a lot longer and shines better too
also check out pid temp controllers there pretty cheap and work great
i also made 2 racks that slide on angle iron right at the top so you can load all the parts to the racks and swap as you shoot the powder
Dave, did you ever put out a materials list for this build?
I don't think there is really a need for a list just source an oven or two and make a frame from some tubing and add the walls and insulation
Take two house ovens, cut opposing sides and hook together. Im still working on the door
What are the dimensions? I want to make one to at least fit a 20in rim
I love how much of a coincidence this is. I am looking to build an oven to coat my own stuff for MY fc lol
Great build. Only thing I dont like about it is the top element..

Use a dishwasher soap tablet to clean the window. It works great! Just dip it in some warm water then rub it all over the glass!

Just pull everything from the donor oven and transplant it there are only 2 wires for the element and 3 wires for the power and grounding
Right on. You took out the middle man. Just in convenience alone. Its totally worth it.
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!
i use to just leave mine outside lol
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?
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)?
Yes, absolutely
Be sure to outgas those car parts to get contamination out and ensure good powder adhesion?
I also seen one guy using the large burners mounted on the side to jump heat, once it reached temp he was able to turn them off. Thanks great video.
What is the caulk like stuff used inside the oven? Sorry, I haven't spent as much time around caulk as many of you, and never experienced dark caulk..
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?
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.).
#2 best content on your channel your first one was with the wiring harness for the 240 where you started and finished on the same vlog way to go Dave.
10 dollar 250 watt heat lamps go up to 500 deg .....Set the height above your part, check temp with gun , Dun
You should just replace the oven controls with a cheap PID controller. You could get way more consistent temps, and not have to worry about temperature readout.
awesome video! can you mount the heat elements on the sides instead of topand bottom so you can put bigger parts in it, like a 55 gallon drum?
I ended up doing that
Good vid I have been contemplating an oven of my own but with different dimensions once again great vid
You can use silicone pipe for a door seal
How much Watts you put in that oven?
Mine is like 1m x 1m x1m Outside and 90x90x90 inside. And i bought 2x 2650Watts heat elements.
I dont know if this is enough lol 🤣
Any chance for a materials list for this? Some buddies and I are trying to start powder coating and would love to make this.
Great build, but I have a few questions. Excuse me if they aren't well articulated, but I'm new to powder coating.
Would it have been easier to use an upright freezer and modifying it?
Did you consider a high temperature fan to circulate the air or is it necessary?
Thanks in advance.
A fan would be good but it would have to be low flow so it didn't blow off the powder and I'm not sure how a fridge would like heat
Lol, I think the "veal" setting should be listed on powder coat specs😂
Medium Rare looks about right for gloss black.
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
Thanks for the video, I have a small job I need to do and have been thinking about doing the same. Now I just need to get busy.
Kaowool is no joke, respirator recommended when working with the stuff... Or fibrefrax, I don't know what brand you're using
What was the size of the oven you built and how many heating elements did you use? The thermostat of the oven did you use it too?
I noticed you use regular insulation. I understand that melts at a very low temperature, well under 365°F used for most glazes. I got some fire rock (rockwool) for my oven that I haven’t built yet. That cost $50 for a small amount, considerably more than regular insulation. I have a lot of regular insulation and would like to use that if I can. What was your experience with this? I got the prior information off of Owens Corning literature, but I did another search and a site tells me that regular insulation will go to 1000°F. Now I’m more confused! 🤗
My oven hasn't caught fire yet so I guess its good lol
It takes a lot more than oven temps tp melt fiberglass insulation.
I'm too late BUT... I WATCHED THE WHOLE " SCHPEEL " OF YOUR VIDEO!
LOVED IT, BUILT MINE OUT OF POLISHED STAINLESS 304L !,
Respectfully, Seth.
Did you weld the piece of the knuckle back on? Looks like you just cut it off. Are you not worried about weakining it?
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.
Lol...yes I am going there....""WELL DONE"" 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
So did you have to find an electric oven and then wire it?
Yes I used 2 ovens
I think you said in the video that you bought an oven in which you use the heating elements in the new powder coat oven that you made. Is the new oven that you made run on 110 or 220 V?
@@reidjensen569 all house ovens are 220
@ thank you for clarifying.
Is it safe to use galvanized steel in an oven? What temperature does the zinc start off gassing at?
I was going to gut a stand up freezer to make my oven.
Good idea Terry, I was going to the same with an old one my parents have. Make sure you have the refrigerant captured; there is bound to be places around you that will do it for free (that already recycle fridges) or for a low price. I think I'm going to turn the one I have into a worm farm (ha ha!) and build a larger homemade oven to be able to do much larger pieces for an experimental airplane I've just started.
@@michaelz6870 the ex-wife was going to give me one but I didn't have room for it so it went to scrap. after I get my garage built whenever they give me the permit that'll be one of the projects that I will do
@@terrycarter8929 Nice man. While the delay must suck, all in due time my friend :-)
Keep us posted!
Im considering building an oven, but I wanna do burglerbar doors and windows. I live close to the sea and.everything here rusts like crazy.
what kind of fiberglass insulation are you using, and doesn't it matter? I want to try to build one myself and be able to learn as well how to powder coat.
What are you thoughts on doing it almost exactly the same. But with aluminum square tubing instead of steel.
Save $7,500 on your build
Step 1: buy $7,500 in tools
Joking, kind of. In all seriousness, great job. Definitely the best build I’ve seen on RUclips.
I recommend you to pre heat your parts after you de greace them and just coat them directly out of the oven while still hot. then just toss them back in.
That is a bad idea it collects powder well but will chip and crack easy
Would be good if you could do a sand blast cabinet that's bigger than normal too
I was going to make my own powder coating oven and use a steel cabinet 6hx4wx2d. I’m just not sure how much power is required to heat up an oven element. I know there 220 but could you run one of a 12v each or even off its own 110. How power did you need for those two elements?
Do a big plate of cookies, no joke, see how even that oven heats, you would be surprised how most ovens don't heat evenly everywhere, you might find you don't have enough elements.
I moved both elements to the sides on the bottom it works much better now
This is a AWESOME build!
Hey Dave!!! When you get more comfortable with this, do you think we (Denver people) could come down and pay you to powder coat stuff for use?
