Thanks for all the help. Plenty of ideas here to get me going. Hopefully I actually have time this weekend to get back to it.

Nice work Janderson.
This is probably way more complicated than it needs to be. The tommy bars didnt line up at all well while being tight with the t-slot but I still ended up making it work. Measuring the angle the tommy bars where from the t-slot was the hardest part. I indicated the rotab t-slot parallel on the mill x axis. Inserted the tommy bar and used a dial indicated mounted in the head to measure the change in y over 20mm and used trig to get the angle. However there is a decent amount of play in the tommy bar hole so it wasnt super precise.
I have two chucks from Sherline, the newer chucks are thicker so made two different mounting locations that match each chuck.
