chuck thread size

>This may be an odd question....for my lathe I need a M30x3.5RH insert. What I don't know is the size of the thread of the NOVA chucks. I have often wondered if it's a 1x8, in which case I could take opportunities on chcuk specials.
Thanks.

>Ruth, The chuck body is threaded with something larger than 1 inch and in fact larger than an 1 1/4' because you screw an insert in that is threaded on the outside to match the chuck body and on the inside to match the shaft of the lathe. Mine is 1 1/4". I looked at the chuck and at the book that came with the chuck, but I don't see the info. Probably can get it on the Teknatool web site. I'm guessing it fits some lathe that has a large shaft and inserts are required for everything else smaller.
