Nicely documented write up, Jim. Thank you for posting it.

Nice work. I think that would be nice improvement to my Atlas I am building up.

What a lot of people don't know is a 3 piece thrust bearing has a lot dimensions there are 2 Ods and 2 IDs, the larger od has a larger id, that is the stationary race, the smaller id fits the shaft. I have repaired or replaced a lot of bearings that were installed incorrectly.
 
Very nice write up and I can see where this would be a huge benefit to an Atlas lathe for sure. Thank you for sharing this.
 
Jim, thanks for yet another great writeup, wich I promoted to an article and placed in the Lathes section of the Home Page (Articles).

All,
I just completed my thrust bearing mod . I pretty much followed Jim b's plan. His method proved to be pretty much spot on.
What I didnt know was what to expect on the lower unit. so here is my take. few pics posted here but most are linked on my
personal site. for more detail.
Also, the drawing I provided is in Visio format. I think I can save it as a dxf file too.
Fwiw. I posted this as jut another persons view/solution of the same problem. I hope it helps you if you endeavor to do the same.
But once again big PROP'S to Jim B... as the original poster.

level of difficulty? I give it a 4 on the 10 scale.
And, Im no machinist. In fact I bet I have less than 10 hrs behind a lathe.
now the drill press? thats another story..

Site and all the pics are here (more detail)

But, I posted a few pics below.
