You would need the LO mount #274-0210 at $121 from Enco, probably get a
sale price sooner or later. But the L series stuff seems to be much more
expensive than D series.
Both of these already have L-0 mounts.
You might check to see if your bad chuck has a removable backing plate.
Or, it it really trashed, you might be able to machine off the chuck and
just salvage the backing plate.
I will try to see what I can do with the bad chuck. It does have a
removable backing plate. But if a used "good condition" 8 inch three
jaw chuck costs just $50, which is what I just paid on ebay, then it
may be uneconomical to do much with it.

I bought a brand new import special 6" 3 jaw chuck from an e-bay
storefront a couple years ago. About $90 including delivery. Made a back
plate from a chunk of hot rolled plate with the 1-1/2x8 thread for my
Logan. Runs about .002" TIR. This replaced the original that came with
the lathe, had about .020" TIR.
My lathe has L0 mount, a little harder to make. Did you buy yours from
Discount Machine?

I tried to find an inexpensive three jaw chuck for L-0 mount to
replace my bad three jaw chuck. Finally found these two ebay items:
300285582565 - Bison 3 jaw L0 mount 8 inch -- $50
300285584382 - Bison 3 jaw L0 mount 10 inch -- $127
I may end up keeping just one of them.
I cruised enco for the above. Condidering the discount from new, I doubt you are going to
get a bargain. Pry that wallet open and get a small chuck for stuff over 5C collet sizes
and use the 4 jaw for the rest.
Maybe I am missing something.
Enco lists a 8 inch three jaw Bison chuck -- with no backplate -- for
$854. See their item 272-6002. I bought a 8 inch three jaw Bison chuck
with L0 mount, for $50. (first auction).
Enco lists a 10 inch Bison three jaw chuck for $1,095 (item
272-6004). Again, no mount or backplate. I bought a 10 inch chuck with
L0 backplate, for $127.
I think that it is not a bad discount from new. You are right and they
might have problems. But then they may not have any problems. Most of
the stuff that I buy does not have undisclosed problems. The seller is
a 100% feedback and he says they are in very good condition. And, why
would he have two bad condition chucks?
If all goes well, am going to sell by bad Burnerd chuck with full
disclosure of its alignment problems. I might get $10-20 for it.

I'm not going to ask you how many items you have turned so far but if if has been seldom,
then keep your eye out for a deal and use the 4 jaw. I have a 6" L00 that I have not
mounted since the 4 jaw was attached and I yet to feel that the time saved by a centering
chuck beat the time and effort to remove the four jaw.
Neither one of us are running production. Keep the 3 jaw in the nice to have column and
if you get a deal, gloat. Until then, just use the 4 jaw, and get a collet setup for the
small stuff.
