Wanted: 6" 3 jaw chuck, D1-3 mount

The jaws on my 3 jaw chuck are quite worn. And, while I'd like to take a stab at grinding them at some point, I'd like to see what's available out there for mid-range new or decently priced good used in the mean time.

I'd prefer direct mount rather than adapter plate but whaddya got?

TIA
 
If getting a new to you chuck, I suggest the kind with keyed / interchangeable jaws. The inside outside clamping is done by removing the attaching screws and flipping the jaw around. New jaws are available if ever needed, and you can also easily mount soft jaws that are machined to suit the job if special needs arise.
I bought mine from Grizzly 10+ years ago, but seems they don't have D1-3. Shars have been a good (US based) supplier for tooling. Here's an example
https://www.shars.com/6-3-jaw-self-centering-scroll-lathe-chucks-d1-3-2-piece-jaws - thats their cheapest one.
There are non-asian variants that will easily triple that price, but thats a start for you (i.e. this Bison, https://www.kbctools.ca/itemdetail/7-803-0633 )
 
Yeah, I've been looking at those 2 piece jaws.

I have reservations regarding "cheaper" chucks, a la Shars. I'm concerned about quality & longevity. Maybe my concerns are unfounded? I've come to learn that "cheap" rarely equates quality. And no, I'm not conducting rocket surgery here

I've been fantasizing about that Bison & have found a couple vendors south of 49 that, even w/ exchange, are almost worth considering:


Bison 7-803-0633 6" D-1-3 3 Jaw Universal Lathe Chuck with two-piece jaws

I also looked at this TOS from KBC, even going so far as to order one but, of course, it's NLA:
