Re: [CAD_CAM_EDM_DRO] Slightly OT broken JT in chuck

If you open the jaws of the chuck and look inside you may find a hole in
the back, giving you access to the end of the taper. If so, insert a
punch and give it a good smack with a hammer. In the past I have drilled
a hole in a Jacobs chuck to do this.
