On my 12" Delta bench-top DP, an effective way to lock the quill down is
to rotate the depth stop dial back around the other way, and lock it
there (i.e. instead of stopping the quill from going down any further,
the quill stop prevents the quill from returning.)  

This works great for inserting a drum sander into a hole and stopping it
there.

Of course, if you require that the quill doesn't go up OR down, then this
won't work.

It's easy to install a quill lock on your Delta 16.5" drill press. Just
in front of the quill spring on the left side is a bolt which projects
into a groove on the quill to keep it from rotating as it moves up and
down. 

Remove that bolt, then take a piece of threaded rod and grind a rounded
end on it, similar in shape to the end of the bolt you removed. Cut off
about 3" (or to your preference) of the threaded rod and polish the
rounded end so it won't score the quill. Make or buy a knob and mount it
to the other end of the rod. Then put a washer, a compression spring,
and a second washer on the rod (to keep it from rotating as the drill
press vibrates.)

That's it. Turn it clockwise to lock the quill, counterclockwise to
unlock. I made this modification to my drill press a couple years ago
and have been very pleased with the results.
