This may/may not help, but I was in the shop this morning and took some pix and measurements.

By way of explanation, I have three Nova chucks … two older G3’s and one Infinity. I am told that the Infinity is the same as the SuperNova 2 with the addition of the quick change slides.

I have two sets of bowl jaws for the Infinity … the #2 jaws came with it, and I added the #3.

My measurements may/may not match Teknatools specs … I measured with a digital caliper.

Expansion Mode

Infinity #2 Jaws
Min: 63mm
Max: 85mm

Infinity #3 Jaws
Min: 78mm
Max: 100mm

Spigot Mode

Infinity #2 Jaws
Min: 43mm
Max: 65mm

Infinity #3 Jaws
Min: 58mm
Max: 80mm

Here is the Infinity with the #2 jaws installed:

Here is the Infinity with the #3 jaws installed:

For comparison, here is the Infinity with a set of #2 jaws that came with one of my G3’s (I added Infinity quick change adapters):

My two G3’s are both direct-threaded for a 1”x8tpi. To use them on the Nova 2024, I picked up a spindle adapter from Best Wood Tools. Here’s my collection of Nova chucks and jaws:

I have not felt the need to upgrade to a Nova Titan chuck yet … if I need to turn something that exceeds the safe limits on my Nova chucks, I have access to a shop that is equipped with PowerMatic 3520b lathes and OneWay Stronghold chucks.
