so if you decided NOT to use a Sunlite/YST unit (I have not been impressed by the quality of some of those products in the past, but maybe they have improved?)
Here's my WAG since this is a thing that really needs to felt in-person, BUT
if it spins in that freely (just with fingers) I would definitely use LocTite on the very clean threads. Blue (medium strength) would be my choice to try first since Red (high strength) is a bigger commitment. If Blue works after test rides and time then you'll be set and the cup will be removable when it has to come out.
