ACG solve should be min area, 35 is just the required parts (I/O + bonder + projection + rejection + arm), and without a track it should be impossible to build polymers on a bonder without swinging them. P.S. it is *technically* possible to build polymers with a piston, but i would need to build the 2 dowsing rods in order, and that means either storing 5-6 quicksilver (if building silver rod first) or being these 5-6 quicksilver short (if building golden rod first). You could get 5 quicksilver from an additional input, but there just isn't space to store this additional input AND manipulate the atoms. P.P.S. i hope that the guy who ordered this shipment of dowsing rods is not going to sue us :(
