It would be cool to maybe have a pulverizer! Thus providing a means of duplicating raw ores, transforming, for example, a raw iron into two pulverized irons and thus making two ingots instead of one, it could be combined with some type of electric furnace. Another thing is that it could be possible to make some kind of machinery to perhaps dismantle items too, like a dismantler or a separator, which when you place an iron sword would separate and deliver the sticks and iron used for that item, of course it would only work for blacksmithing items such as tools, armor and blocks such as anvils, chains and lanterns
