See http://pico-systems.com/bridge_spindle.html for how I added a spindle encoder to a Bridgeport that had no provision for getting at the spindle with a traditional encoder. I used the existing gear on the spindle and added sensors to make it into a quadrature plus index encoder. It works great for rigid tapping.
