A multipurpose woodworking tool of the type having a frame, a pair of parallel way tubes extending longitudinally of the frame, and a headstock mounted on the way tubes in which the improvement comprises a pair of yokes joining the way tubes together at ends thereof, pairs of upright members at the ends of the frame and spaced apart to receive one of the yokes therebetween, and an apparatus extending between the yokes and the upright members which enables the way tubes to be changed in elevation between a lower elevation optimal for utilizing a table saw attachment mounted on the way tubes and a higher elevation optimal for utilizing a lathe attachment. In one embodiment, the apparatus includes spring-loaded pins which are sidewardly displaceable from the yokes, and holes positioned at at least two elevations on the upright members to be engaged by the pins. In another embodiment the apparatus is in the form of a pair of rods which are inserted through pairs of holes formed in the support legs and upright members at the desired elevations. In a third embodiment, the apparatus includes a pair of pins fixed to the support legs and positioned to slide in a vertical direction in slots formed in the upright members. Lever arms having notches corresponding to the desired elevations are positioned in the upright members to be engaged by and to support the pins. In each embodiment, the yokes can be disengaged from their respective members so that the way tubes may be pivoted to a vertical position.
