The Fafnir and many others including imports are far better than the TB3
and 4.

### Anything is better than a TB3 or TB4. UST uses PEER brand
thrust bearings for both the big drum, and the mast. The ones used on the
mast are NOT designed to self align. The thrust bearings on the big
drum ARE designed to self align. They come with a locking collar, that
has a couple of holes, spaced 180 deg apart, on the top portion of the
locking collar. Just rotate the locking collar CW a bit and it binds tight,
then
use a drift punch in one of the 2 x holes, and give it a gentle smack. Then
the locking collar wont budge. Locking collar also comes with a set screw.
Replace it with a SS type, then slop some never seize onto the threads of both
the SS set screw and also the threads of the collar.
## The TB3 /4 although popular, are not cost effective, not for what you are
getting.
