Watch the video of Stuart Tankard making tiny valve handles on his CNC lathe. Changing the old Boxford spindle motor to a new generation servo motor allows him to use Mach3 to control the spindle to turn very slowly and to a set number of degrees, producing the very attractive handle cut-outs and rim dimples. i.e. he has added the functionality of an indexing head to his CNC lathe.
It required adding a small milling head and motor to the toolpost.
I can see one of these on my Boxford 125TCL in the near future.
