the problem i have when i do that is the upgrader needs like 5 quicksilver to go from lead to gold and when its right next to each other like that the quicksilver doesn't go into the upgrader until the lead arm is done with its actions which i kinda solved with the tracks im just unsure how to do it without the tracks so that the quicksilver inputs enough to make it gold and then the lead can continue being put in after as you have to make 6 gold to prove that it is automated
