New chuck for Rockwell drill press 11-280?

[Johnny_Block]

Sometimes, a hole can be drilled through the chuck towards the spindle and a punch inserted into it and when the chuck is supported on the vise jaws and the punch given a good whack with a hammer, the spindle will be knocked free of the chuck

There may already be a hole in the chuck. Can you tell by this photo?

I now have the spindle with chuck out of the machine. Now what? I've been searching online videos but I'm not finding how to get this chuck off. Do I set it on a vise (chuck facing upward) with the spindle between the vise's jaws (loose, not clamped) and tap the body of the chuck on top of the vise's jaws?

Johnny, you have undoubtedly found a way to separate the chuck from the spindle by now but on my drill press the quill and chuck were still on the machine. I used vice-grips to hold the pulleys and a pipe wrench to twist the chuck free. I did not know at the time that the chuck was mounted on a taper.
