This is what I've been using for 14+ yrs. to cure bake on finishes. Had the box made at local sheet metal shop, 12"x12"x 48" shoebox style. Put a 4 coil 220 volt oven element with oven control, and a thermometer mounted in the lid. Wrapped the outside of the box with insulation, the hard board type used in furnaces and covered it with plywood, with angle iron legs. Put an oven rack over the element to protect it and lay a piece of the insulation board on top of that to disperse the heat to the ends of the box. Was going to mount a fan for that purpose , but found I didn't need it. all the metal get's to the proper temp without the fan, checked with a lazer temp. devise. Drilled holes in the top flange of the box and use bent coat hangers to hold long parts and pie pans for small stuff. Hang bolts, trigger guards, and other parts on wire hooked over coat hangsr wire.
