Thought I would post a few pics of my home made powder coat oven for those interested, also useful for curing guncoat , dura coat and all the other heat cured paints out there.
I started with an old punch card cabinet that was designed to hold cards for an old NC milling machine since it was double walled and big enough to hang a complete ma duece or mg42 in . I used the shelves to make a couple of doors which are hung with 4 std door hinges from the hardware store . Nothing fancy any old metal cabinet could be insulated and made to work, like a filing cabinet etc. Since my cabinet is double walled I plan to pour the walss with perlite or some other insulating material. I also still need to instal a gasket for the door.
