I want to buy this chuck but it says ‘does not accept threaded inserts” I dont know what that means and if someone could explain to me what limitations this will cause it would help determine i this is for me.

I dont know what the inserts are or what they are used for…I am wanting to use this with the mini cole jaws and am worried that it wont be compatible.

If I understand it correctly, the threaded inserts refers to the threads on the head stock. Some chucks can be used on differently threaded shafts by using an insert threaded into the chuck. You should probably buy the chuck that matches your lathe.

You are correct lew. The inserts are for different size arbors on the lathe. I have the Nova 3g, the guy at the show where I bought it. Said that it was better because if you happen to change lathes with a different size arbor, all you have to do is to change the insert. Also any products that come out in the future from the vendor will work with this chuck.

Ok well here is where the confusion comes in. I already own a nova midi
chuck. An mine screws on to the headstock! I wanted an extra so I could mount the bowl jaws in and not gave to remove them. So are there different versions of the original (I know there is a nova2 but both of these are the original).

The bottom of this page lists two versions. One which takes inserts, and one which fits 1”-8 threads only. If the threads on your headstock are 1”-8, then it’ll fit.
