Hedd, The problems with using a baking sheet is that it is usually of an unknown hardness, I know that when Jamie and I first looked at producing the silicone gaskets we tried "Lakeland" baking sheets. The guys cutting them out soon rejected them as useless and supplied Jamie with proper silicone jointing. Unfortunately I cannot remember what the Shore number is!
