I was fortunate to get my lathe with three chucks, but as I have used them over the past few months I have realized that my 6" 3-jaw needs the jaws reground, the 4-jaw is in excellent shape, but better for larger work (8") and also slow, and my 8" three jaw is in decent shape, but quite heavy for the lathe.
I was torn between a collet system and a 6-jaw, do to the expense of each, it would only be one for the time being.
I decided on the 6" Bison 6-jaw set-tru with the Bison set-tru backing plate. The quality and finish are excellent.. But I have one complain, the pattern for the four adjustment screws to dial in the run-out of the chuck is an "x" pattern... This makes it much harder, as it doesn't act like a tru 4-jaw system. After 15 minutes I was able to get it to .001-.0015", if it was a standard 90 degree apart system I feel I could have got it to zero-ish.
I was also able to pick up a Hardinge 5C speed chuck minus the backing plate. Building a set-tru backing plate will make a fun project.
Thanks,
Marco
