hello

My Nu-tool (ex B&Q) drill press has a B16 spindle which fits into a
matching B16 socket in its 1/2" chuck (chuck is labelled "B16"). I
remember following the original chuck fitting instructions, 15+ years
ago, which said to push the drill press spindle down into the rear of
the chuck.

I now want to upgrade to a keyless chuck but I am unable to remove the
original chuck because:

How about, find a M12 bolt or similar, feed it up through the hole in
the table (with washers if necessary so the head will not pass through
the table). Lower the quill, and grip the end of the bolt in the chuck.
With appropriate adjustment of the table height, you should now be able
to use the quill leavers to lift it away from the chuck which is now
pinned to the table and can't lift with the quill.
