Indexing detent override mechanism

A motorized miter saw comprising:

• a base having a turntable mounted thereon for rotation about a vertical axis;
• a cutting unit having a mounting means for securing said cutting unit on said turntable for movement to non-cutting and cutting positions relative to said turntable;
• an indexing means for releasably securing said turntable in predetermined positions of angular adjustment including a detent receiving recess on said base at each predetermined position, a detent alignable by rotation of said turntable with any one of said recesses and a detent biasing means constantly biasing said detent into a detent engaged position in the specific recess with which it is aligned;
• a detent override means selectively positionable to allow movement of said detent from a detent engaged position in said recess to a detent withdrawal position and free said turntable for micro-angular adjustment relative to any predetermined position;
• a latch means for releasably securing said override means in said detent withdrawal position thereby preventing said indexing means from engaging said recess during micro-angular adjustment about said recess;
• and
• a locking means for releasably securing said turntable in any selected position of micro-angular adjustment.
