I've had my X3 now for 4 days, and overall am very happy. THis is a solid mill, the perfect balance for my living situation and needs.

One thing though, the geared head is a drag. 2000RPM max is pretty slow, and the gears are noisy. My thoughts are to gears with cast iron, balanced pulleys, and a 4L size V belt. Belt from pulley on motor to shaft. Ideally, I would get a max RPM of around 4000, for drilling smaller diameter holes. Has anybody here done this, what are your thoughts?
