[QUOTE="Timber_MG, post: 36209, member: 18"] Drive the screw and not the nut (much simpler). Place a bearing on the bottom of the screw (if metric this is really simple with a nut and a washer). The drill is reversible, perhaps use some micro switches to control the up/down movement. To drive the nut would require a belt configuration (and much more complex bearing mounts), allowing you to change gearing and drive at a greater speed (screws whip over a certain speed) [/QUOTE]
