Agreed on the CA... I use "water thin" to soak in and harden the

I always unscrew the lathe chuck and leave the piece mounted in it,

Not only toxic fumes but I've also had some wood that generated
intense heat...

Try a 1- or 2- lb cut of shellac. Soak the piece for a while, then let it
dry. Be aware that it will change shape, as it absorbs the liquid.

Or paint it liberally with thin CA glue. But be aware, IF there is any
moisture in the wood (and with punky wood there always is) you are going to
generate some serious fumes that will drive you out of the room, so do this
either in a VERY well ventilated room or outside.

With either the shellac or the CA, you will probably have to reapply after
you have have worked on it a bit.

The advantatge of the CA over the Shellac is drying time. While shellac
dries quickly on the surface, it will take a bit longer deeper down. CA
will be ready to go in a couple of minutes, or by the time the fumes clear.
