Abstract

A device is provided for measuring the centre of a grinding wheel for use in setting the height of a skate blade. The device has a base, a support extending from the base, a slider block slidable along the neck between the base and a head block secured to an upper end of the neck, a dial indicator supported by the head block for measuring the position of the slider block along the neck, a lower roller, and an upper roller. The lower roller and upper roller are rotatably attached to the slider block and radially aligned with each other such that a portion of each roller protrudes from the slider block, wherein a clockwise tangential force imparted on the upper roller causes the slider block to slide along the neck, and the dial indicator to record the movement of the slider block, which enables the height of an object to be set on the dial indicator with respect to a rest position of the slider block.
