This solution outputs as fast as possible, except for one cycle where the spinning arms pause to grab. The cardinals section either produces a wheel of the input element or, if the input is metal, a wheel of salt in a different position. These wheels take salt grabbed from the input at rate 2 and duplicate them or dispose of them respectively. The metals section produces two wheels: one holds the number of quicksilver required to project lead to the input metal, and the other holds five minus that number. These wheels are used to transport quicksilver to the projector and disposal respectively, which is best seen with intermediary metals like iron.
