Got a lathe too ? Buy a chunk of metal and make a mount plate for an
off-the-shelf chuck . Square piece just a bit bigger than the chuck diameter
, turn it to fit the chuck back , slot the corners . Mild steel seems to be
a pretty decent choice , price-wise . Haven't checked cast iron , but
aluminum and brass/bronze are pricey in Memphis Tn .

A lathe 3 jaw chuck on a faceplate. Mount the faceplate to another.
And have the non-lathe one T-mount and larger. Or just buy a Bison and
a backplate - and go from there.

Like others have mentioned, I made my own. A round disc slightly larger
than the chuck to allow room for cap screws around the chuck, with 3
holes in my case as the 10" rotary table has 6 slots. The cap screws go
into T slot nuts which I had already made for the table. The plate is
shouldered like you would fit a chuck backplate, A nice feature is I
also fitted an accurate centering plug in the middle of the disc so I
can just fit the chuck on the rotary table and it is centered, the plug
is removable so I can fit the chuck and backplate straight onto the mill
table if required.
My second-hand rotary table has tapped holes all over it from previous
fixtures. None of them weaken the tee slots and they don't interfere
with using it. Why not screw the chuck directly to the table? If
there's room, you could use undersized mounting screws and make blocks
that screw down in the tee slots with lateral screws to center the
If the three front screws go through a ring of solid metal in the
chuck, maybe you could drill a 4-hole pattern in it as well.
