I have not used this yet. And yes it is questionable as to how well it will work on a shopsmith with a stock tail stock. What is nice is that you have a very fine adjustment as to the depth of cut and feed rate.
I'm looking forward to trying it out sometime soon. I also have a small modification I plan to try on the tail stock.
AH for time to do all that I want............

Wrong, cham-ed. You have X and Z confused.

Thank YOU!!
Not at all what I expected!
Z-< >+Z < left >right
X-o ∙+X o AWAY ∙TOWARDS
Y-ccw? cw?+Y about
either X or Y axis???
Interesting X and Z are first two dimensions and Y the third!
Does make sense for a lathe - traverse l/r and in/out.
Not sure how that relates to a milling machine(vert quill). I would expect quill to be "Z". ????? Would have to be left handed coordinates???
This is getting too deep for a retiree!!!

You are exactly right, JPG.
On a mill,
Z axis is your quill or spindle with Z+ going up, and Z- going down.
X axis is left to right, X- is left and X+ is right (completely opposite directions of Z axis on a engine lathe).
Y axis is either moving away or towards you, Y+ is away from you, and Y- is towards you (again, completely opposite directions of X axis on a engine lathe).
