Bought this a few weeks ago, and so far so good. This is a great deal as it includes several sets of jaws for a great price. I was overall impressed with the quality of the machining, although I did file a few of the tougher edges.
Interchanging the different jaws is easy, but requires you to do the job of lining them up. If you dont get it just right, youll have to re-align one of the sides. Perhaps a pin or shoulder would ease that. It comes with all of necessary bits and pieces for all the jaws, and the chuck mates with each set of jaws via numbers. everything has its place in a foam lined case though fully included.
Overall, a great starter set for someone looking for options when it comes to woodturning chucks. Ive used many brands of lathe chucks, and this does not disappoint!
