If you intend to use your 3 T slot lathe chuck on the rotary table it will have to have a matching number of slots. I have a 4 slot rotary table to match the 4 slots on my lathe chuck. Have a look at previous posts for rotary tables and my photos.

I bought & fitted a four slot chuck mounting to the four slot rotab' I' bought last year, not having a tapered central hole but tapped with a Whit' thread for some reason?, never the less I machined an adaptor to suit the thread in the rotab & recess in the back of the 3 & 4 jaw chuck back plates, which both happen to be the same. I used the adaptor to centralise the rotab' & then centralise the job to suit using the 4 jaws, or if using the 3 jaw it centralises itself, (I double check with dti) . I remade the clamping plates & T nuts out of decent steel as the supplied fittings were the usual Chinese crap metal & substituted cap screws for the hex head bolts supplied, much more secure clamping. I have a short set of pics in my album if you want to cast a glance in there.
