I tried to caliper the different aspects of the turret and could find no difference. By turning the quick change turret with the screw driver (pry bar) after a couple hundred turns I can almost turn it by hand now! I am tempted to try the square ratchet again, but it looks so frail, that I just know it will spin off the indexing rod?

update:
You would not believe the amount of metal (aluminum) filings, as I put the index rod back in the turret, the pilings were piled on top of base. Anyway cleaned up the mess took some sandpaper to each turret and they now work ok, the older one's rotate much better, disappointed in the QC! -thanks for all the input-
