[Elecraft] (K3) Assembly (again) Front head

[Terry Schieler]

That's exactly what I experienced on #474 just after I built it.  The washer
rattled.  There were a few supportive posts here alluding to the same issue
at that time.  However, Elecraft support said it was something obvious that
I had done incorrectly in construction.  I went back and retraced all the
hardware assembly on my front panel and all was consistent with the manual.
Trying to tighten the knurled nut further with my fingers simply deformed
the front panel until I released the pressure.  All the buttons and other
projections were equal in their distance from the front panel and were
visually "spot on". All functioned perfectly.  I ended up putting a small
glob of hot glue on the washer to stop the noise.  Slept better that night,
if nothing else.

I tried that first. In my case it resulted in what I considered an
unacceptable deformation of the front panel. Maybe I just had a bad stackup
of tolerances. YMMV!
