Abstract: A multi-faceted T-slot cylinder for a cutterhead is mounted to a wood lathe arbor using set screws installed in tapped holes which are provided near opposite ends of the cylinder in diametrically opposite faces of the cylinder (rather than in the same face, as is conventional). Static balancing of the cylinder is thereby improved. For fine-tuning, a dynamic balancing collar is mounted on the arbor near the cylinder. This collar has a plurality of tapped holes provided radially therethrough around its circumference. As the arbor is turned slowly, if measurement shows eccentricity in rotation, the high side is determined and a set screw tightened against the arbor in the respective tapped hole. This dynamic balancing can be done before or after the cutterhead is installed on the arbor, and the dynamic balancer can be used in combination with a wholly conventional T-slot cylinder.
