Abstract
A power module for providing power to any one of a plurality of special purpose woodworking tools has a variable speed headstock on a base, and a tool support carriage on the base. The tool support carriage is formed with two pairs of tube-receiving sockets for receiving the support tubes of a special purpose woodworking tool. The sockets are formed at two different levels above the base, such levels corresponding to the difference in spacing of the input shaft connections with respect to the support tubes. The base is mounted for movement toward and away from the headstock, providing alignment of the input shaft with the headstock hub. A variable speed drive in the headstock employs an intermediate three-section pulley of the variator type, and a speed control knob is connected to position the variable speed drive to provide for the selection of speed for any particular tool.
