In this video I finish the connecting rod. It was partly machined on my little Sieg X3 CNC milling machine, until the PC which drives the mill gave up the will to live and the remaining ops had to be completed on the Bridgeport and the Colchester lathe. I also detail the prototypes for the piston and give you a sneaky preview of how the engine will sound during starting.
