There have been posts on here in the past about making your own gaskets with a sheet of Lytherm(?). I have ordered an exhaust blower gasket for my Mt Vernon AE to use as a pattern. Although I seem to have found it for a reasonable price of $22.95 (comparatively speaking), it still seems a little expensive to me. Does anyone know what thickness of Lytherm to order - 1/4" or 1/8"? Is lytherm the best material? I have read on other blogs that people who have made their own gaskets have experienced "hot odors" when the stove was running on high temps.
