[CW] Vibroplex Original Damper Wheel

[stan levandowski via CW]

 Thank you, David, and everyone else who responded.  I have standard 
4-40 hardware and the screw is indeed "too long" and obviously not 
original.  It didn't even look right since the screw extended beyond the 
nut for quite a distance.    I'll just thread the nut on, cut the screw 
off and reassemble with a dab of Locktite Blue unless I can find "more 
correct" hardware.
73 and Season's Greetings,

The Original damper wheel moves around, I just tried to take two of them 
apart, I cannot do it with my fingers, the nut on the back will not 
loosen all the way.  Same with the other key.

I have never had the damper wheel fly off.  I have had them tighten up, 
but I just back off on the forward screw.  I do not remember if this was 
other people's bugs or mine, but I check my bug often.

Damper wheel moves.

Weights tightly screwed on.

Adjust dash distance.

Adjust dash tension.

Clean contacts with stiff paper.

Check for 10 solid dots.

If something doesn't sound right, I investigate.  Common malfunctions 
are dirty contacts, poor ground due to ground terminal being loose, hot 
terminal underneath straps dirty or loose.  Dot U spring loose on 
Vibrator.  Oil on dot lever tension spring on deluxe post 1980 bugs.  
Broken or loose ground strap on deluxe pre 1980 models.  Oil or grease 
put on trunnion pivots:  clean off!!

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,
