You didn't miss much. I have the Jet version and the 4 jaw was just about unuseable. I used it 1 time and spent close to an hour trying to get the stock properly centered. Everytime you touched it, everything moved resulting in lots of tail chasing.

I also bought a 6" Bison 3-jaw at the same time. It's a lot heavier than the 4 jaw and it simply hasn't been an issue. The 9 x 20's use tapered roller bearings about the same size as the front wheel bearings GM used on full sized cars where loads are considerably greater than anything you could put on that lathe without destroying it.
