I have a Talon chuck (standard jaws that came with chuck) which I use on my Jet 1642. I recently started to do hollow forms to 6" depth. Eventually I'll want to do HFs with a 12" - 14" depth. I need to know if my Talon with standard jaws will provide enough holding strength, or, should I get larger and/or deeper jaws for the Talon, or a larger chuck (Stronghold). Thanks.
