Hi Andy;

Thank you for the response - I have seen your little 7x lathe cnc
conversion on a few places - well done.

I'll readily admit to being a bit "newby" in encoders.

The Compact-8 does have a 40 tooth gear on the spindle. Right now spindle
pulley is off, because was doing some measurements on it for someone in
Britain who specializes in threading clutches - he needed a Compact-8 to
measure.

Was thinking that, while it was off, I could make up a large disk with
holes for the encoder.  Would it be better to read off the 40 tooth gear on
the spindle??  To me, in my novice state, I'd think that was not as good,
but...

With the ebay rotary encoder -  I can mount that and drive it either via a
timing belt, or simple gear - I have a set or three of change wheels for
the lathe, and I'm sure one could be put into use.

Hmmm - I'm going to look at these rotary encoders more. I'd think that I'd
still need a timing pulse though.

Thank you - John A. Stewart.
