Taig indexing plate supplied by Nick Carter was adapted to my Unimat SL 1000 lathe and milling/drilling head modification. The plates can index 40, 50, and 60 divisions. Index plates are attached with adapters made from 12L14 steel. The first version of the adapter uses a set screw to secure it to the headstock pulley/spindle and the second version (an improvement) uses the pulley locking nut to secure it and does not require drilling into the pulley for threading a set screw. The headstock and milling head pulleys were re-machined on their collars where the index plate adapters attach and concentric to less than +/- 0.0005" to the spindles. The index plate indents can be locked in the up position when the plates are rotated between index positions and unscrewed a few turns and locked with a cap head screw when the spindles are operating under power.
