I need to build an oven just big enough to fit a barreled action in. 40" would be more than wide enough for my largest firearm project.

Do you suggest I build it with the 40" lengthwise or heighth wise? I though lengthwise would be the most efficient and also distribute heat the most evenly.

The depth and heighth would only need to be about 15 or 16 inches.

Could I build this with a 1.5" angle iron welded frame, skin the inside with 18 gauge steel, attach eye bolts to ceiling at various locations for hanging parts and use sheet rock for a couple of inches of insulation? Then make another 1.5" angle iron frame outside the sheetrock.

I figure a heating element set out of a normal oven would heat this size of oven adequately for powder coating.

For the door I still do not a good idea on window material, hingeing or sealing gasket material. I figured I might use glass or plexiglass for the window and gate hinges to hinge the bottom of the door. The top of the door could be latched with a gate lock or sliding lock. Just thinking out loud as I am sure if this would work well.

Any thoughts or oven pics would be greatly appreciated.

Thanks,
Darin
