Question: can dwemer gears be smelted?
Answer: An easy rule of thumb is that if it starts with the word "Dwemer" (dinnerware, cogs, gyros, etc.), it can't be converted, not even Dwemer Scrap Metal . Bent Dwemer Scrap Metal can be smelted. The Small Dwemer Lever is an exception; its name doesn't start with Dwemer, but it still can't be smelted.
