A while back someone mentioned video recording the workshop classes and offering them on DVD. Since I will not arrive until Thurs evening at best I will miss most of the classes that have the most interest to me (CL and HAL). On another note, has anyone done much with electronic gearing? I have an old horizontal mill that I would like to convert to a gear hobber, it looks like if you had an encoder on the spindle to track its rotation and a servo on an index head to rotate the work piece it could be done by setting a ratio between them. The problem I see is that the spindle might have to turn several hundreds of times for a complete cutting cycle. Can be done without running out of counters? Ed
