ABSTRACT:
An apparatus (50) for detecting lateral deviation of a band saw blade (36) from the desired line of cut which includes an angularly displaceable element (54) slidably engaging the saw blade (36) for pivotal movement therewith. A relatively rigid mounting assembly (52,64) mounts the angularly displaceable element (54) for rotation while resisting lateral displacement. Lateral blade deviation is proportionately determined when angular displacement is sensed by a sensor (55) as the blade (36) contacts the displaceable element (54) rotating it about an axis (53) through the desired plane of the blade (36). The angular deflection sensing assembly 50 also may be incorporated into a guide arm (32).
