ABSTRACT:
The saw includes a frame having an opening with a pair of proximate and distal blade retaining chucks located on respective sides of the opening. A saw blade is retained between the pair of chucks. A plurality of pulleys are attached in spaced relation to the frame including pulleys on opposed sides of the opening. A flexible band is entrained about each of the plurality of pulleys, with the band having a first end operatively connected to the proximate blade retaining chuck and a second end attached to the distal blade retaining chuck. A reciprocating drive is attached to the proximate blade retaining chuck. The reciprocating drive and the flexible band work in conjunction to pull the blade in opposite directions during each cycle of the drive. An alternative embodiment of the present invention may take the form of a stationary table saw.
