I did take the Old Glory apart last week to change the cam size. I was impressed by the very tight fit of the axle to both the bearings and the limbs.
This is encouraging , especialy after thousands of shots , I got a darton 2 years ago and brand new I had to change out the top bearing , it was very slopy , the bow shot well but the top cam wiggled 1/4" .
This is good news , and relates to the original post .
