[Boatanchors] National NC-101X Knob Setscrew question

[WA5CAB at cs.com]

A Heli-coil will probably work, at least if the knob is solid rather than 
hollow, and not now cracked.  And if putting the tape in the hole didn't cause 
the screw to chew out too much more bakelite.  The problem with Heli-coils is 
that you can't buy just one.  And the special tap and installer may cost more 
than a new knob would (if you could still buy a new knob).
