you can do that silently with a different system for your droppers, (simple and redstone light as well), btw, challenge accepted, been looking to downsize the AutoSmelt 3000 to the home version, the AutoSmelt 1000. Big enough to handle those crazy weekend smelting parties, but small enough fit right next to your enchanting room.
just a couple of quick notes, if you lower your furnace and you use droppers to lift items to your chest after the furnace, instead of lifting them when loading to the furnace, you will decrease the amount of droppers used by half, since you would only be raising the items once, instead of on both sides of the furnace.

Hope I pronounced your name right ^_^'
