    I have several Vibroplex keys.  The only one with this screw is the only one with jeweled bearings.  Perhaps there is a connection.   Willis Cookie Cooke

      Bill,

      I finally seen the screw you are talking about.  On some speed keys, it was a way to fix the height of the pendulum.  there are press fit arbours,
      there are captured arbours (sandwiched between between two pieces) and some used such a screw, either directly into the arbour or set with
      a grazing, but capturing position.  I cannot find my reference as to when Vibroplex used that method and discontinued using it.

      Sorry if this was answered before. I am search for some e-mails and cleaning up/out others.

      It's on the views marked "partial view".  On the Frattini j36 is an allen wrench adjustment but I've seen regular slotted screws on vibroplexes.

      Tell us where you can see this screw.  I don't see it.

      On several, but not all, lightning bugs I noticed a small screw just distal to the dash tension spring.  It's presence is not noted on the lightning machine drawing located on the vibroplex site but I have seen it on several ebay pictures and it is also present on the Frattini J38 reproduction.  Does anyone know it's purpose?

      My Vibroplex Champion, 1952 has the capture screw for the arbour or trunion pin. It is an slotted oval head screw that is in the dot bar. All of my other keys

        My Vibroplex Champion, 1952 has the capture screw for the arbour or trunion pin.  It is an slotted oval head screw that is in the dot bar.
        All of my other keys here are press fit, from the 1913, 1920, 1928, a friends 1945 to my 1991 original.

        The Deluxe had a fillister head screw that captured a small ring lug on a ground wire.  That ground wire went down to a screw
        on the bottom back side of the yoke.  Because the Deluxe had a jewelled bearing, the trunion could not supply ground to the
        dot and dash bars, thus no ground to the dot or dash contacts when they were closed.

        But the screw that Bill asked about, I saw it on the Italian bug and it is a hex set screw and some Vibroplex had the screw in nearly
        the same spot for locking the dot bar's height.  I did not even realize my '52 Champion had it until I just looked at all my keys here
        in Texas.

        If you look at the parts list for an Original, Part# O-29  or 1005 is for a trunion lock screw, but you will not find it in the machine drawing.
        Same with the Champion, except it part number C-26 or 1005.
