What is that on top of the mill's head? Drawbar or a place tomount encoder?
Yes, the spindle is a splined, two part thing and the hollow top of
the spindle stays in place, regardless of the Z axis position (bottom part). This means that mounting an encoder on the top is very easy, just a little machining exercise to make something that I can stick inside and make it stay connected to the spindle, with some little top piece to mount encoder wheel. |

Correct. Try something that will expand into the top of the spindle. Its not a "wet" area, so your choice of materials is quite wide.

Let me think. it would be a fun and inexpensive improvement. i |
