Hoblick Posted January 11, 2015 Report Share Posted January 11, 2015 so a few months ago i decided i was gonna get back in to powder coating. this time i wanted a decent size oven so i could do several things at once, or bike frames, or an entire set of wheels or whatever. ive been working on it here and there for about a month and here is the progress. im gonna try to finish most of the oven build up by next weekend, and i have a friend coming in to town that is an electrician for the coal mine, very talanted dude. He is going to be wiring up my elements, PDI controller, thermocoupler, SSR, and running my 220 off my panel.hoping to have this thing fired up after that weekend. internal dimensions are 5' x 4.5'x4.5' i still have to get some hardware for the door and a seal, as well as some more insulation. but for the next weekendim gonna finish my ceiling panel, sheet some more, start building the door, and then install a rack system for the ceiling to hang parts from. this picture is for size reference.. and this is where im at thus far 2 Quote Link to comment Share on other sites More sharing options...
Pokey Posted January 11, 2015 Report Share Posted January 11, 2015 Boredom can cost ya time and money huh buddy? It's coming along, you will be baking in no time. Quote Link to comment Share on other sites More sharing options...
Strictly Street Posted January 11, 2015 Report Share Posted January 11, 2015 Damn! You could do an entire (insert object here) at once with that thing! Quote Link to comment Share on other sites More sharing options...
ReconRat Posted January 11, 2015 Report Share Posted January 11, 2015 (edited) I would insulate the bottom also, for multiple reasons. Makes my recycled toaster oven look pathetic. I'm going to guess that a lot of wheels might run through this rig.Kind of exciting considering how many powder coat color combinations are available. I assume you have plans for sand blast and media blast units also.As well as some "dip to clean" immersion tanks.

claine650 Posted January 11, 2015 Report Share Posted January 11, 2015 Will gladly bring you a couple sets of wheels, valve covers, and other odds and ends to test it out, you know, so you can be sure it's working correctly [emoji6] Quote Link to comment Share on other sites More sharing options...

I assume you have plans for sand blast and media blast units also.As well as some "dip to clean" immersion tanks.the bottom is insulated already.im going to make some cradles for wheels to sit in, im wanting to be able to do 2 full sets of car wheels at a time. i have a blast cabinet, and going to buy a portable pressuizd blaster for larger things i cant fit in my cabinet.

Hoblick Posted January 19, 2015 Author Report Share Posted January 19, 2015 a little more done tonight.wheels are on it now so i can roll it around..got the other side wall skinned on the inside, made my ceiling and skinned it, mounted my heating elements, and insulated the top.next is building the door (waiting on my door seal as well), then next weekend my buddy is coming up to help me get everything wired and then the rest will get insulated and sheet metal skinned. and shes ready to fire.

Hoblick Posted January 19, 2015 Author Report Share Posted January 19, 2015 (edited) oh and im making a rack system for the top of it so i can hang whatever parts from it. this build is a little over what i thought the initial cost was gonna be. about $350 over lol Edited January 19, 2015 by Hoblick Quote Link to comment Share on other sites More sharing options...
OsuMj Posted January 19, 2015 Report Share Posted January 19, 2015 Very cool. How are you/are you going to add internal circulation (for more even temps throughout)? For curing do you need to worry about ventilation at all? I've never looked into it, just curious. Quote Link to comment Share on other sites More sharing options...
Gump Posted January 19, 2015 Report Share Posted January 19, 2015 Wondering the same/\. Looks great! Quote Link to comment Share on other sites More sharing options...
Hoblick Posted January 19, 2015 Author Report Share Posted January 19, 2015 some do circulate air, to help get temps up quicker, but its not critical. the PDI controller will regulate the temp such as a standard oven will. it will use a thermocoupler to sense temperature and shut off when that temp is reached, kick back on when it dips below. and a PDI controler is alot more accurate, within 1 degree, vs. a household oven regulates around +/- 10 degrees.

whaler Posted January 19, 2015 Report Share Posted January 19, 2015 (edited) You may want to shield the heating elements and allow room for air on the top and bottom. This will keep the radiant heat from baking the powder to fast. The shield will also help you create a natural convection up the walls and will keep temperatures closer to average with respect to what the parts see.Also...just me being anal, but its PID (Proportional, Intragal, Deriverative) Edited January 20, 2015 by whaler Quote Link to comment Share on other sites More sharing options...

Hoblick Posted January 26, 2015 Author Report Share Posted January 26, 2015 nearly there. its wired, it functions correct.got my door seal on, door built, and one latch on lol.i have just a few small things to tend to, but i did fire it up and just to see it run and get to temp. 1 Quote Link to comment Share on other sites More sharing options...
whaler Posted January 26, 2015 Report Share Posted January 26, 2015 Nice! Get the shields on there, all that radiant heat will be a problem. Quote Link to comment Share on other sites More sharing options...
