I've tried the spline and it doesn't seem to get in deep enough to 
engagae without stripping.Maybe I should "dress" the end on the 
grinder?I'm thinking that a small phillips with long "teeth(?)" would 
work.

Jay,

As Mike indicated, the two smallest Bristol drivers are four-flute 
instead of
six.  The smallest knobs (usually the locks) on a lot of military sets 
use
them.  O-16 and O-17/ART-13 come to mind.  You probably need the 0.050 
Bristol
driver.  The Walsco and GC wrench sets came with them, as did the 
Xcelite one.
Some of my Xcelite drivers are wound up from loosening locking knobs on 
the
oscillators, and also on Command Set transmitters.
