I once had to deal with a chuck that someone had glued the arbor in with red locktite. (And we didn't know that it was locktited.) First tried to use the wedges, no luck. Eventually we wrote off the arbor and cross-drilled it so we could put a dowel pin in there and have something more robust to push on. Still no luck. Wound up chucking the chuck in a lathe and boring the damn arbor out of it. We ultimately reduced it to a shell about 0.010" thick and then peeled it out of the hole. What a PITA.
