Looks almost like the first version
This board may look familiar to some of you. Because at first glance, it looks just like its older brother described here: Dividing Head Controller. But many things have been improved in Revision B.
I’ve just finished the variable-frequency drive (VFD) for my 1970s Schaublin 102 lathe. Before I dig into details, there’s a youtube video here:
This post ist about the CNC conversion of a manual dividing head aka indexing head. If you’re not familiar with that kind of equipment, there’s a wiki page here. One makes use of interchangeable indexing plates and and the internal worm gear to accurately divide the circle. Parts like cogwheels and the like can be machined this way. A video of the finished project can be found here on my youtube cannel.
