Patent ID: 8166860

Claim:
A miter joint forming system comprising: a miter saw including: a platform including a first surface and an opposed second surface, the platform including a peripheral edge, a cutting device coupled to the first surface of the platform, a kerf slot extending through the platform, a first generally arcuate slot extending through the platform and disposed in spaced relation from the kerf slot, a first fence slidably coupled to the first arcuate slot, wherein the first fence is configured to support a workpiece disposed on the first surface of the platform, and a second generally arcuate slot extending through the platform and disposed in spaced relation from the kerf slot, a second fence slidably coupled to the second arcuate slot, wherein the second fence is configured to support a workpiece disposed on the first surface of the platform, a first fence support member movably coupled to a first guide disposed along at least a portion of the platform peripheral edge, wherein the first fence support member moves along the first guide such that the first fence support member is repositionable with respect to the peripheral edge of the platform, the first fence extending from the platform to the first fence support member, and a second fence support member movably coupled to a second guide disposed along at least a portion of the platform peripheral edge, wherein the second fence support member moves along the second guide such that the second fence support member is repositionable with respect to the peripheral edge of the platform, the second fence extending from the platform to the second fence support member, wherein each of the first and second fences is movably coupled to the platform to permit the displacement of the fence from a first platform position to a second platform position to selectively alter an angle at which the fence is oriented with respect to the kerf slot; and a measurement tool configured to measure the angle between intersecting surfaces, the measurement tool comprising: a housing, a first measurement plate pivotally coupled to the housing such that the first measurement plate pivots about a pivot point, a second measurement plate pivotally coupled to the housing such that the second measurement plate pivots about a pivot point, wherein the measurement plates cooperate to define an angle therebetween, wherein the measurement tool is configured to couple to the platform of the miter saw.
