[Elecraft] Splitting knobs - a thought

[Ken - K0PP]

I've often wondered if the threads in the batch 
of knobs that tend to split were incorrectly tapped 
with a taper tap instead of a straight tap.  

A taper tap would not be able to run fully through 
the set-screw hole due to hitting the opposite side 
of the shaft hole.

This would result in a tapered thread that would
force the knob apart as the straight set-screw is
screwed in.

It would be a hard-to-catch error on the part of
the vendor of the knobs that even they themselves 
or the employee that did the actual tapping may 
not have been aware of.
