[j_tenkely] wanted to do his own powder coat painting at home so he built everything he needed, including a coating booth and baking oven. The oven is double walled and built around a frame of steel building studs. Electric oven elements are controlled by a digital control panel and thermostat.
A spray booth is fashioned from a large storage bin. The powder coat gun used in this setup is a commercial project. But don’t fret, this is something you can build rather than buy.
