[Spridgets] No LBC ....used watch makers lathe wanted for my students.

Look at this:

http://www.use-enco.com/CGI/INLMK3?PMK0NO=1179288

It should show 3 very similar options for "finger chucks" that mount in the
drill press (or lathe) chuck and allow the operator to peck carefully with
tiny drill bits to produce very good holes. Many many machine shops use them.
