I'm adjusting the height of the support arm & knife on the Oneway from AZ carbide to the Korpro. The Korpro cutter has a slope to it and I have the front point of the cutter at just a hair above center spindle height. Haven't seen anything in instructions video about where best center height should be. Would like to hear from others about where they locate it i.e. dead nuts center, just above or just below.
