[CW] Vibroplex Champion Question

Sat Aug 31 11:45:03 EDT 2019

No, that centering is fine.  It's the place on the circular damper wheel where the little bump on the end of the lever shaft contacts it.  I think the bump should hit the middle of the wheel and not the far edge.  It works but is annoying to the eyeball.  

I know, picky.

Thanks and 73,

If you are talking about hitting the top or the bottom of the damper
wheel, the adjustment is the trunnion adjustment screw located below
the trunnion and accessible by a slotted screw on the underside of the
bug. The other side of this adjustment is at the top of the trunnion assembly - it centers the whole vibrator.

The Lightning Bug, Champion and Zether all used the same vibrator parts.

Here is a diagram with names for the parts used by Vibroplex.

One of the keys I recently purchased was a black Champion.  As I stated in a previous email, someone tried to convert it into a left handed key by turning it upside down.  I have since repaired that activity but I notice that the button on the end of the lever bar is not hitting the center of the damper roller but is almost to the edge.  I see no adjustments for this issue.  I wonder if the lever bar belongs to a Lightning bug and not the Champion.

Thoughts?

Many thanks and 73,
