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.
