I wanted to do some simple indexing on my lathe. I already had the arbor for the spindle that
was made previously for my manual hand wheel.
I had also made a spindle rear spyder and found that useful also.
So all that was needed was an indexing plunger and some wheels with a bunch of holes.
I settled on 60 holes and 72 holes which seem to cover most usual hole patterns.
CNC machine was rusting away in the corner of my shop so I thought it would be good for this.
Made the index wheels out of polycarbonate since I had a large stock of it.
The hub is just aluminum with a set screw to engage the flat on the existing arbor.
Two FH allens hold the plate to the hub and that is it for the plates.
The plunger was made out of aluminum bar stock and some drill rod. The plunger is
spring loaded and operated by the cross rod as can be seen in the picture.
I was surprised how well it locks the spindle in each hole. Should be a good addition to my home shop.
