I have never had the need to cut gears in any of my projects and my Emco rotary table in manual guise has always served me well. However, after an exercise developing an ELS system for lathes, together with a few MEW forum members, one of said members 'conned' me into developing an electronic hobber, photo 1.I did not intend to build the mechanics for this, but as this development exercise was taking place between folk seperated by many thousands of kilometers, I did need some sort of test bed. So, my Emco rotary table was used to do the job. During the process I also made some chuck attachments to make it easier to align a workpiece for mimimum runout, and made the drive electronics do a whole lot more besides just hobbing. The stock rotary table was modified by fitting a drive pulley to the Worm shaft, and fitting a stepper motor with similar pulley and drive belt, photo 2.
