I just purchased a Longworth chuck for my Jet 1642..The disk on the back of it is 3”. The 2 sets of chuck jaws I have for my Nova G3 and Nova Sn2 are max 2 1/2” (50mm) and the other the minimum is 3” (Powergrip jaws).. I need to be able to tighten down to 3” Hmmmmm which jaws do I need? The manual and description of the jaw range arent clear to me. Thanks for any help!!!

Either the 70mm or the step jaws. The 70mm are about 1/2 the price and IMHO 4X more usable.
Look at the spigot range.

Craft supplies has a video, and description on there site. Says the chuck comes with a 2 1/4” adapter and is intended to fit A oneway #2 jaw set. As long as the dovetail jaw set is somewhere in the 2 to 3” compression range I think it will work fine.
The first link is for the chuck, and the second link is for the oneway jaws. All the specs are there on the jaws, so you can take that info and match it to a set of nova jaws.

quick edit, I just noticed you said your chuck has a 3” adapter? I don’t know anything about nova chucks. If a G3 is in the same size class as a oneway stronghold chuck, then the #2 jaw size still work. #2 on a talon chuck are a little small.

For clarification, the Nova G3 is nowhere near as robust as the OneWay Stronghold. The G3 is a lighter duty chuck that is more like OneWay’s Talon chuck. Nova’s Titan is roughly equivalent to the OneWay Stronghold.

Thanks, I had no idea how the nova chucks are sized. I use Oneway, and vicmarc myself. After some lite reading this morning, I’m not sure there will be a nova G3 jaw set that will hold that longworth chuck. I was surprised by the lack of information I could find about the Nova chucks.
They don’t seem to have as many options for jaw sets as some of the other brands.

The 70mm jaws will work for the Longworth chuck. I also have the SN2 ..(Super Nova 2 Chuck) which is heavier than the G3 and I have the power grip jaws which work well for heavier stuff but are too big for the Longworth chuck. Thanks everybody..

I agree. Unless the G3 is equipped with Nova’s Infinity retro-fit slides and jaws, I wouldn’t try to use it with a Longworth. I have 2 G3’s and an Infinity … the Infinity is a SuperNova2 with quick-release slides and jaws.

Here is a fairly complete rundown of jaws and accessories: http://www.novatoolsusa.com/Chuck-Accessories_c6.htm

Mike Turner, if you had one of these, you wouldn’t be having a discussion on what jaws you now need. The only concern would be what size MT would be needed for the tailstock IF your lathe was a Oneway.

With the following assumptions..
Your are using it at a low speed <600?
Item is finished/balanced except for cleaning up the base.
Your G3 should be fine but since you also have a SN2 you can use it if it makes you feel safer.
I would personally be more concerned with the wood coming dislodged from the Longsworth more than the Longsworth being dislodged from the chuck.

Id definitely be using it at low speed.
I would use the tailstock p to where it would hold the piece and it wouldnt dislodge then.

Depends on which jaw set you are using. Nova has a number of jaws for the Infinity (see: http://www.novatoolsusa.com/New-Infinity-Chuck-Range_c18.htm ), or you can purchase adapters to use other Nova jaw sets with the Infinity chuck body.

If you took a look at my post #9, you would see there is no need to use a jaw set over a 50 mm or 2 1/4’” opening. The Tail Stock Steady is so simple even you could use it. Being that the piece is between centers while removing the tenon completely, there is a lot more security during completion. Also, there are no nubs to get your knuckles busted on. ............Your buddy, Jerry, (in Tucson)
