What size of chuck to get ?

[woodfarmer]

I am currently working on a project that requires me to mill some ratchet teeth on a round bar. I have decided to mount a rotary table on my toolpost but need to have a chuck on it to hold round bar of 52mm diameter minimum. (not long lengths). would the 65mm chuck with this table work? or do I need to get something bigger. I don't mind reversing the jaws if need be.

Thanks for your help

You won't be able to hold 52mm (or anything like) in the inside jaws of a 65mm chuck. You might just get away with it with outside jaws, but the Chronos offering in your link doesn't appear to be supplied with a set, and it doesn't look like the jaws are reversible.
RDG do something similar with outside jaws which may be more suitable.

As an update, Have found

Which is perfect for me, one way or another it will cope with 2" bar.
Again, many thanks for steering me in the right direction
