[CW] Vibroplex Original Damper Wheel

[stan levandowski via CW]

The 1943 Original I'm restoring has a damper wheel with flat head 
machine screw and a nut.


This looks exactly like the Vibroplex site's mechanical drawing, just 
the three parts.


I'm a bit confused here -- If I tighten down on the screw/bolt, the 
damper wheel won't have any play.  If I don't tighten it, eventually it 
can loosen. This doesn't seem like a very good design and I'm afraid I'm 
missing something.  Perhaps the Original model isn't supposed to have a 
"loose" damper wheel?? 


I realize I can double up on the nut and/or use Locktite Blue but I'm 
curious to know if this is the actual design from 1943? Can someone with 
an Original take a quick look and let me know?


Of all the bugs I've owned and operated over 50+ years, the Original is 
one bug I've never operated, owned or even taken a close look at  ;-)


Thank and 73,
