I've got a 4 jaw chuck, and this was my first attempt at facing off the curved bottom of a picatiny rail. You can probably tell it wasn't centred by the circle centre being to the side, but that seems to be an advantage of the 4 jaw, and it's ability to adapt to uneven shapes. But this turned out well, as it was to be used to mount a bipod.

do you have self centering 3 jaw chuck?these better for general use,maybe can get you one if you havnt got one mate,holding small items like scope rails in chuck,they need be packed from behind to keep them aligned correctly,proberly better done on face plate mate as item can be fixed directly to face plate as will then be machined parallel, on both faces,i dont do much mill work on lathe these days but have made up a clamp for the height adjustable tool holders for the quick change tool post for jobs like scope rails and use fly cutter in chuck to do the machining,any run off when maching rails will affect the amount of adjustment available in the scope,dosnt take much run off to run out of scope adjustment.you can get fully adjustable milling vice setups for tool posts that make milling lot easier on a lathe,these are not that expensive but worthwhile if you only have a lathe mate as they make milling lot easier and the lathe more versitile in what type milling you can do on a lathe.let me know if you want a self aligning 3 jaw chuck and face plate and will see what i can find for you.
cheers mike
