I have an aluminum framed skeletal box I'd like to powder coat. The box is made from 1.25" square tubing and is roughly 44 * 24 * 12. If all goes well, I may have a continual need to coat objects of this size.
While the powder coat gun and powder are readily available. I need to build an oven. So I thought I throw out these ideas and get some feed back.
#1 Find an abandoned household refrigerator.
Gut all the plastic and styrofoam material inside, remove the separation between freezer and fridge compartment. Weld the doors into one structure. Wrap the exterior with fiberglass insulation, and add two standard electric oven heating elements and thermostats, and possibly some type of fan...
#2 Build something...
First thought was to get some metal framing studs, build a large box. Line the inside with either sheet metal ? OR ? cement board (like used for bathroom shower stall walls to stick ceramic tile to). Insulate the exterior, and again add some heating elements, T-stats, and a fan or two..
#3 Build something #2
Any chance I could just pour a concrete pad, build concrete block walls, and fabricate a removable sheet metal insulated roof? Will concrete deal with 500F temperatures?
Whatever gets built, will it need fresh air ventilation?
