Abstract
A table saw includes a table disposed on a housing, a plate supported in the housing, a follower rotatably secured to the plate with a pivot axle, a saw blade rotatably secured to the follower with a pole and rotated in concert wit.h the follower relative to the plate. A motor is coupled to the pole, with a pulley-and-belt coupling or the like, for driving the saw blade via the pole. A threaded shaft is engaged with a gear sector of the follower for rotating the follower relative to the plate and for moving the saw blade upward and downward relative to the table.
