My Delta not-Rockwell drill press has a collar on the down feed spindle

slips too easily and the hole gets drilled too deeply.) I'm going to
retrofit something better and I have a question about another form of stop.

The drill press that Marty has on eBay now:http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=120108960046
has a stop based upon a threaded rod. See picture #10. Am I right that
this form of stop is adjustable by turning the stop nut a 1/4 turn and
sliding it? Is the nut in 2 pieces that jam together to stop
unintentional movement?

Is there another form of stop that is better?

Thanks,

The only ones I've used with the threaded rod had NO form of quick-
release, you wore your fingers out running the nuts up and down.
Also, the jam nut never seemed to and vibration loosened the works
up. Either that or the bolt holding the threaded rod unscrewed and
dropped out in the middle of the operation. Hate that form of stop!
I bought a pushbutton quick-release nut for a Bridgeport once hoping
that would make things a little better with one drill press, it didn't
fit.

On the old Delta I have now, the stop is in the form of a drum about
3" in dia, has fine graduations, horizontal axis. It has a wing nut
that's loosened to set it. It never loosens up in the middle of
things. I seldom see this form copied on far east clones. There's
other things I don't like about it, but the drill stop isn't one of
them. The threaded rod is kind of cheap-ass way of doing things,
particularly where there's no quick release on the nuts and the
supporting collar around the quill is plastic, like so many of the
cheapies are these days.

You can replace the acme thread with a ..***..cant remember the
thread..the same as the Bridgport and THEN use the cheapy clip on stop.
