Probably the most commonly available chuck fitting in the model engineering field is the Myford. You can easily pick up faceplates and chucks from EBay and elsewhere with this fitting. Otherwise just stick with the MT2 taper and use soft end blank arbors machined to take whatever chuck you want to use. Many dividing jobs such as gear cutting could be done on an arbor or mandrel directly fitting into the MT2, but to make sure the job doesn't slip use a drawbar to hold things snug.
