Thankx, 7018
I have no doubt I will finish the project.
I'm just not very good at wording things, I'm trying to make it educational for beginners.

Drill and ream the hole for the spindle bearings.
I use what is called an edgefinder to locate the edge of the part then zero the dials on my table. and from there I just move the required amount where I want the hole to be.

What you do is place the edgefinder in the spindle, run it about 800 rpm.
Slowly make contact with the nose of the edgefinder, keep moving the table the tip will visually line up with the shank of the edgefinder Then when you go past .001 of that, the nose will veer off and at that point you know that you are .099 from the edge of the part assuming that your using a standard edge finder with a .200 diameter nose.
I don't recommend the double ended edgefinders they don't hold very well in chucks.
