Nick spins up his balancing machine. It's fuly computerized--just enter the component weights and it tells you which bob weights to use. The machine then ramps up to 250 rpm, and if it's within a certain inbalance tolerance, then it goes to 500, and at the point you get it to within 15 grams on each end, then it spins up to 750 rpm. The machine tells you exactly where to take mass out of the counterweights. You turn it to the predetermined point so it lines up with the drill bit, and based on the diameter of the bit it tells you the depth to drill. View Related Article
