An improved compound miter saw is disclosed as having a selectively rotatable turntable mounted on a supporting frame and a power driven saw blade pivotally mounted on the turntable between a lowered full cut position and a raised full retract position. The turntable is provided with a saw blade slot for receiving the power driven saw blade when lowered to its full cut position. A work supporting fence is mounted on the supporting frame and turntable and includes a pair of work engaging surfaces longitudinally aligned across the saw blade slot. The work supporting fence is constructed to provide simultaneous longitudinal and transverse movement relative to the power driven saw blade so as to maintain the work supporting fence in a predetermined relative position to the power driven saw blade as the turntable and included power driven saw blade are selectively rotated on the supporting frame to various desired miter positions. The compound miter saw is further constructed to provide selective releasable engagement of the turntable and included power driven saw blade with respect to the supporting frame at various pre-selected miter positions of the power driven saw blade relative to the work supporting fence. For this purpose, a leaf spring with self-locating ball detent mechanism is employed between the turntable and the supporting frame for selective releasable interengagement therebetween.
