Separate Jacobs chuck from CAT40

[slow-poke]

Do you think it would be easy to separate this chuck from the CAT40 arbor?

I don't have wedges, assuming the CAT40 is hollow all the way through perhaps a tap with a punch from the draw bar end? Assuming that end comes off?

Or perhaps I would need wedges?

It should come off easily with wedges. Chances are, if you remove the pull stud it's a through hole though, but be careful hammering on that end, as you could mushroom it, and make removal more difficult. Not impossible, but difficult. A press would probably be the best option, supporting the holder on the v flange.

Not hard to make custom wedges. Lots of room there for a nice set. Then a regular bench vise squeezing the wedges together will pop it apart easily.

I agree with @Dan Dubeau. If you don't make/find/buy wedges, then use a press, not a punch. Even then very carefully. Wedges are best.
