Bevel adjustment mechanism for a compound miter saw

A compound miter saw comprising:

• a base;
• a turntable rotatably mounted to the base having a planar upper surface;
• a fence assembly affixed to the base;
• a saw assembly including an elongate arm having a fixed end pivotally attached to the turntable, a distal end forming a handle and a central region therebetween;
• a motor assembly having a motor housing provided on the elongate arm, a rotary spindle supporting a cutting disk and a motor disposed within the motor housing operatively connected to the rotary spindle;
• and
• a bevel adjustment mechanism for adjusting the angle of inclination of the cutting disk relative to the turntable upper surface, the bevel adjustment mechanism including
• a first knuckle for adjusting the angle of inclination of the cutting disk about a tilt axis including a fixed portion mounted adjacent the outer periphery of the turntable having a locking flange extending radially outward from the tilt axis, a rotating portion cooperating with the fixed portion having first and second opposing flanges disposed in a plane generally perpendicular to the tilt axis, wherein the first flange includes an arcuate channel spaced radially outward of the tilt axis and the second flange includes a scale provided thereon cooperating with an indicator on the fixed portion to measure the angle of inclination of the saw assembly relative to the tilt axis, and a locking mechanism extending through the arcuate channel in the first flange of the rotating portion into a passage formed in the locking flange of the fixed portion to secure the rotating portion to the fixed portion, and
• a second knuckle for pivotally adjusting the arm assembly between an inoperative position and a cutting position about a pivot axis, wherein the second knuckle includes an inner periphery having an annular rib, a groove cooperating with the annular rib, and a torsional spring disposed within a pocket cooperating with the annular rib and groove to control the rotation of the second knuckle about the pivot axis.
