Got some more shop time in today.
Finished up the bottom portion of the base. Added the 2 mount holes to attach the base to the cross slide.

Test fit it on the lathe

Then I took the other chunk of stock and faced it off.

Shaped the bottom of the upper base so it will fit the bottom part of the base.

I took the piece out flipped it around and cleaned the top portion up (forgot to take a pic). Then did a test fit again.

Brought the top part over to the mill. Added the slot for the tool, counter bored the center hole (for the bolt that connects the two pieces), and added the 2 access holes for the mounting bolts. Again, I forgot to take pics for the during. But here is the result test fitted to the lathe:

The access holes are so the base can be mounted and unmounted to the lathe without taking it apart:

I still have some work to do to the base... added the screws to hold the tool in place and drill and tap a hole for the lever to spin the ball turner. Then I have to make the L shaped tool holder itself. Maybe tomorrow.
