      Joe is correct.  It is a machine screw that presses against the arbour (pivot rod) to prevent it from moving - later Vibroplex's do not have this as they are press fit and basically not adjustable.

      What I do if the height is off on pressure fit arbours is I take a 1 inch think pieces of soft wood that I can hold in my hands 2 by 3 by 1 is fine - I use three soft cloths and I use a bench vise.

      I disassemble the key and remove the main lever from the trunnion assembly, Be sure to disconnect the grounding braid if the key is a "deluxe" version.

      I open the vise and cover each side with cloth thick enough to cushion the blow you will be giving in a moment.  I wrap the arbour (pivot rod) with a thin cloth - just to prevent tool marks..

      Lay the lever across the jaws of the padded vise and close the vise until you are about 1/16 inch from each side of the arbour.  Hold the lever in position and tighten vise until it allows movement of the arbour but doesn't allow it to fall over unless you force it to.  In other words "just holding".

      Then take a piece of wood - cover the elbow end of the pin with the soft wood and give it a whack with a small hammer.  The pin will go down a bit.

      You get the idea.

        Very correct, DR.  If you have as I have and/or made, small pry bars, 2 identical, you can grip the arbour with a smooth jawed vise (covered pads) and I sometimes
        use leather as an additional protection.  I then can apply pressure upwards on the main bar very close to both sides of the arbour to move it up from where it is gripped.
        I cover the pry bars as well.  Occasionally, the arbour is not extended or long enough to grip it, then DR's method is used. I, occasionally, can use my staking tool as
        well, but not a common tool in shops today.

          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.

            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.
