Abstract
A rotational positioning and locking mechanism for the cutter arm component of a cutting workstation. This allows the cutter to be capable of rotation producing a variety of miter cuts. The cutter positioning and locking mechanism will allow positioning of the cutter in a variety of predetermined angles based on holes or stops in the cutter arm into which the lock is inserted. Should it be desired the cutter be placed at an angle that has not been predetermend, a friction shoe will allow the cutter arm to be rotated and positioned and any angle between the angles predetermined by the stops.
