I wonder if anybody has experience with an electric oven modification - and by that I mean a hardcore style mod, not just adding a few bricks :-) Here is more info: I have three cheap-to-free basic kitchen electric ovens (Fridgidaire). I can fit 10 bread pans on one shelf, but would like to double it. However, the top room is 2-3 inches smaller than I need. I have removed both broil coil and a light socket, but it is not enough. The next step was to remove insulation. Looking at the oven chamber I see a common sheet metal, which I think I could cut, add a collar and then weld or rivet back. Just make the chamber a little bit bigger. I would appreciate any ideas on this project.
