[Boatanchors] CCW drill bits

[Walt - WB2VSJ]

If the hex hole has been rounded out, can you jam a small flat head
screwdriver in there (jewelers)  and back it all the way out?

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
