Ok, 36 holes tapped and chanfered on both sides...Done.
Now to align the spindle drill chuck with the center of the rotary table...
Then we can go to the outside and drill the 4 sets of 3 holes to attach the 2 mid rings together...
And finally add the 2 offset dowel pin holes so that everything stays aligned if and when the upper and lower section are seperated...which I hope is not TOO often.

Nice alignment
-------------------- A few I enjoy,
and a few more in the works ;<)
