That's a great idea! My wife has a pile of these (she bakes a LOT), and they are very sturdy. The best part is that they are made of aluminum, so you could collect metal chips with a magnet and not stick to the sheet.Maybe not a tool but close to it. I was in a commercial restaurant supply house and noticed these large baking sheets (18x26) for $8.00. I got several to put under machines as shown in the picture. Cleanup of chips and oil is a lot easier.
