Looking for some guidance from some of you more experienced turners. Nova chucks are on sale at Rockler. Is the midi 1" enough for the Jet 1014? Or should I be looking to stretch for one of the others?

When you say 1inch , you mean the thread in head stock , I assume. I use the wood river from woodcraft. I have 2 thread adapters for my mini Jet1" and my jumbo Jet 1 1/8". Nice product from the price. Adapter jaws available for other needs. Check it out.

Fromwhat is can see at the site as long as your headstock has a 1"-8 thread this wiil work. This chuck is direct attach meaning it will not accept an adapter for another spindle configuration. I have a couple of the nova chuck and others they work well
