The tube attaches by drilling holes in it to match the holes in the az bearings, then bolting up the assembly. The original bearings are not used.
You will not need friction adjustment! The stiction provided by the ebony star and teflon negates the need for that.
Moving the tube for balance after fitting the alt bearings can't happen. Spending some time during set up for locating the bearings is the go. If you use both light and heavy eyepieces, I have a cunning plan to maintain balance with my Lightbridge, happy to demonstrate.
