I want to replace the chuck on a King-Seeley (Craftsman) drill press
and am not sure how to go about it. This is the best set of pictures I
can find on the unit -

Above the chuck is a knurled collar w/ 2 recesses 180-degrees apart.
The chuck is a Jacobson 1/2" w/ J33 mount. Does anyone have experience
with this drill press or have a likely idea on how chuck removal would
be accomplished?

I will appreciate any guidance on this.
