Quite honestly, Eric … I think you might find a 3-Jaw very frustrating to use on the Rotary Table.

It obviously depends exactly what you want to do with it … but in many cases you will probably want to centre a particular point over the axis of rotation.

Have a good think before you decide.

If you only have one rotary table chuck get a 4-jaw. A 4-jaw chuck can be used to hold round bars and is more accurate than a 3-jaw. Does not take long to find the center with a DTI. It can also hold square, rectangular and odd shaped components.

I have use an adaptor to take my lathe chucks which allows me to transfer the job from lathe to mill without removing the job from the chuck. Keeping the job on the exact same center.

I have found it can be quite tricky using an adapter that allows the chuck to screw on, the cutter direction or the rotation can cause the chuck to unscrew.
