Here is the final stage. DO NOT MOVE THE MILL TABLE when changing tools from
hole saw to boring head. If you do make that mistake, and I did, you can 
still align the boring head with Tracy's plate by adjusting the boring
head and the mill table to just fit Tracy's  starter pilot hole. Its 
tedious but it can be done. The other mistake I made is to select
a too long boring bar. Keep it short and stiff to have a better finish
in the hole. Mostly a cosmetic thing.
