You'd rough bore the tailstock to make enough clearance for the
Moglice, fixture the quill in its proper location, make dams as
required to contain the goo, inject the Moglice of the proper
viscosity, and let it set. The stuff cost $25 - $45 for a 50 - 100ml
kit.

Ugh. Having popped a lathe saddle free off the bed after casting
Moglice on the underside of the bed, I'd be afraid you would
never get the ram out of the tailstock. If there was any wear
in the middle of the ram that reduced the diameter even .001",
you'd be completely hosed for sure. The biggest arbor press
in the world wouldn't free that ram. If you go this route
(and Moglice is REALLY great stuff!) make sure you use an extra,
extra thick layer of mold release on the ram. Actually, what
I'd recommend is to make a substitute ram plug that is a couple
thousandths undersize, cast the Moglice and then line-bore the
Moglice for alignment and fit to the ram. Then, you could
establish near zero clearance, without the nightmare of getting
the real ram stuck in there. The pseudo-ram could be any sort
of mockup, maybe even rolled-up shim stock, that would make it real
easy to peel it off the Moglice.
