[Elecraft] new KX-2 question

[Matt Maguire]

Draw a circle on a piece of paper radius R, and mark it's centre. now draw a smaller circle inside radius r, which touches the bigger circle at one point, and mark it's centre. You'll see the distance between the centre points is (R - r). imagine the big circle is the hole in the VFO knob, and the little circle is the VFO shaft. The flat part of the VFO shaft is irrelevant, as the screw is adjusted to meet it wherever it sits.
I hope this help explain how the knob will not be centred.

Leave one screw loose, drive the other one into the flat.  How could it not be 
centered?
