I have a spinner knob for a Collins 75A4 that has a set screw in it that has 
been "boogered" up by a former owner so that the slot/hole in the top of the set 
screw will not accomodate a hex or bristol tool. The knob is off the shaft  so 
the screw should not be "tight" but just in the screw hole and should be easily 
backed out if there was some way to put pressure on it in the reverse or CCW 
direction.

That is why I was inquiring about SMALL CCW drill bits.......thinking a CCW bit 
might set inside the screw head and catch enough to move the set screw out.

Another method, I have been thinking about, is to put a dab of fast drying epoxy 
on the end of a small allen wrench and sticking it into he wallowed out set 
screw head and allowing the expoxy to dry and then turn it CCW. The drawback is 
that it would be difficult to keep from getting the epoxy in the screw hold in 
the brass insert thereby clogging up the hole.

Just thinking out loud in an attempt to determine the best way to back the set 
screw out of the knob. Thanks for the replies. 73, John, K5PGW
