Hi,
I have a Oneway Talon chuck that came with a set of #2 jaws. There are myriads of different jaw sets. I assume that #1, #2, #3 etc. refer to the jaw sizes but I'd like to understand the uses of the different types.. For the Talon chuck, Oneway has the following jaw sets:
  • Profiled* and smooth Spigot Jaws
  • #2, #3 profiled and smooth (dovetail?) Jaws
  • #2, #3 profiled Tower Jaws
  • Flat Jaws
*Profiled is Oneway's version of a serrated jaw.
Thanks
 
The “smooth” are dovetail for the #2 and #3

The profiled jaws are not serrated but are similar l
The profiled jaws have a cove in the center of the separation so each jaw has two wide rounded contact areas.
This provide a superior grip to dovetail jaws on square stock and oversized tenons. - however in most cases the dovetail jaws will hold well enough

I use the smooth spigot jaws for gripping the tenons of finials.

You can do a whole lot of stuff with the number 2 jaws. They hold small bowls, small hollow forms, square stock..
Remove two jaws you can hold a length of 1x2 to turn something in the face of the 1x2.
 
I have a stronghold chuck, same as the talon just larger. My favorite OW jaws are the tower profiled, whichever size. The profiled jaws provide added contact surface vs a round jaw set as they are expanded from perfect circle size, provided greater useful range for a given jaw set.

The tower jaws have ~1/4” deep smooth DT at the top, then the serrations begin. They can be used as DT jaws (with a better grip beyond perfect circle) for shorter items, and the extra depth can be used for taller forms/hollowing (long tenon).

The extra height does not cause vibration. I’ve turned the same forms/wood with the std #2 profiled and the #2 tower jaws and not noticed a difference. The tower jaws provide a lot more/easier access to the foot area of forms.
