[ARC5] Screw lengths for receivers

[WA5CAB at cs.com]

The third (and not third most) common length is 7/32".  Used in the tube 
covers amoung other places.  Probably the original length for bottom covers 
although 1/4" works OK there except for the three across the bottom front for 
which I always use 3/16" without lock washer.

I think that all of the #3 lockwashers were intended to be captive but 
removable with minor trouble.  It's just that, probably due to tolerances, some 
do come off easily.
