Just finished my Cerakote Oven.
$200 for a stainless and insulated used warming cabinet that "might" be working off of CL.
Welded the back door shut and removed all the guts and junk off the top. Sealed, welded, and high-temp foam and caulk'd all the holes, openings, and vents. Welded a piece of 1/8" steel plate on top.
Found a 1500 watt dimmer switch on Ebay for $20 and wired up 5 - 250 watt heat lamps that run on the dimmer. Hits 300 without the deflector shield and 260 with it in, in 50 minutes at full capacity. (didn't go longer to see what it would max out at, but had to drop dimmer way down to hold 250 and not continue to rise) Sides and top don't even get warm to the touch. 40" of hanging height.
Really happy with the results and less than $400 invested in whole project. Added casters this morning so it can roll around shop.
I guess it is pretty much air-tight, because I left the wire hole unsealed so I can add my thermometer wire later this week, and when I open the door and close it, air shoots (whistles) thru the hole for a few seconds each time. I guess this is the cool air equalizing with the hot air inside when the door is shut and latched.... No biggies, just sounds weird. Gonna leave the hole unsealed as I figure this pressure release is needed and good. (don't want a boom)...
