ABSTRACT:
A sawing platform and workbench includes a stand portion and a platform supported by the stand portion. A pair of adjusting plates fixed to opposite ends of the platform adjust the height and angle of the platform. Each adjusting plate has first and second spaced, vertical slots formed therein to permit vertical movement of the platform. The second slot of each of the adjusting plates includes an arcuate slot formed in the adjusting plate continuous with the second slot to permit angular movement of the platform. An adjusting rod includes a first end portion contained within each of the first and second slots to limit vertical movement of the platform over a distance substantially equal to the length of the vertical slots and to limit angular movement of the platform over a range commensurate with the length of the arcuate slots. A second end portion of the adjusting rod is fixed to the stand portion. Locking means lock the platform at a desirable height and angle.
