Moveable saw fence and saw support

A miter saw comprised of:

• a base;
• a horizontal table supported by the base, the table having an upper surface;
• a fence coupled relative to the table and extending vertically upward from the table and being located between the rear edge of the blade arbor and the rear pivot point when the blade is driven, the fence configured to move for and aft relative to the base between a forwardmost position and a rearmost position;
• a support arm pivotably coupled to the base at a rear pivot point configured to permit the arm to pivot about a horizontal axis;
• a circular saw blade arbor supported by the support arm at a location spaced forward from the rear pivot point;
• and
• a circular saw blade supported by and concentric with the blade arbor, the saw blade configured to be rotatably driven to cut a workpiece supported on both the horizontal table and the fence, the saw blade having a rear edge facing the rear pivot point,
• wherein the pivotal coupling at the rear pivot point permits the blade to move along a predetermined arc in a vertical plane perpendicular to the horizontal table from a vertically elevated first position in which a bottom of the blade is higher than the rear pivot point to a vertically lower second position in which the bottom of the saw blade extends below the upper surface of the table, and
• wherein between the rear edge of the blade arbor and the fence in the rearmost position of the fence, the support arm extends substantially above the height of the saw blade to allow clearance to cut the workpiece without interference from the support arm as the saw blade is moved along the predetermined arc and substantially all of the saw blade height between the rear edge of the blade arbor and the rear edge of the saw blade and in front of the fence is exposable to pass through the cut workpiece.
