The quality of Bison chucks is good. I have several three jaws both 8" and 10". They work very smoothly and the reversible top jaws fit beautifully.
But I do question putting 60 lbs on a TL1. That will probably be much more than twice the rotational inertia of the standard chuck and when you have a workpiece clamped in it even more.
If you do get this I would go careful using CSS when facing because repetitively accelerating and deccelerating this mass might overheat your drive.
