Fellas....so I buy a basically new jet 1221vs the other day. To my surprise the lathe came with 4 jaw nova....which looked to be a G3. So I order the chuck key from nova, and it doesn't really fit correctly. I can open and close the jaws by moving the teeth in the back, but the key will not open the jaws. Like I said at first glance it looks exactly like a G3, but there is no "g3" marking on it...only nova scroll chuck
Possibly an older model before the G3? Different key?
Thanks
