SHOP OVEN EXTENSION
If you are using an old household oven for heating parts, you most likely have found it small for some jobs. I made a sheet metal enclosure that sits on the open oven door to expand its size. The enclosure is insulated with some sheet insulation found at a home improvement store. I added two handles for easy moving. I also found that putting a piece of sheet metal over the heating elements helps the parts heat more evenly.
