      Hey Bob and the gang;

      Yeah,.. there is something at the Vibroplex web site... some more stuff in qst (do a literature search at the ARRL website) and finally some bits a pieces recently in the archives herein if my memory serves me right. Plus I am sure some google searching would also be useful.

      One important thing that is somewhat elusive, even in the printed material, is the description of how to set the "dwell" timing of the dash movement. Since your elements are best formed with primarily a wrist rocking movement and (much, much) less finger movement than when you manipulate a dual-lever iambic paddle, the last step in setting up a bug is to set both the spacing and tension of the dash travel. To get the right "dwell" so the dahs are naturally longer sounding (than the dits,) neccessarily means these dash settings will be different than for the dot movement. i.e. When you are rocking your wrist back and forth the same amount from right to left and left to right the dash contacts need to mate longer. We can achieve this by setting the travel of the arm when making a dash shorter and then putting the right amount of tension so your dash contacts "dwell" longer with the same amount of back and forth wrist movement.

      At least that is my story and I am sticking to it !! (And....I hope that helps you out somewhat.)

      So dusting of my bencher and Vibroplex and have a couple questions.

      1. I assume the Thumb ( right hand ) is always used for dashes.

      2. My Vibroplex is chrome and a little worn, but works ok as far as I
      can tell.

      It has a total of six adjustment, is their a detail sheet that talks
      about each indivigual adjustment ??

      Thanks

      ... Actually, the norm is for the thumb to control dits since it is more agile than the side of your finger. I m assuming by Vibroplex you mean a bug, but

        agile than the side of your finger.

        I'm assuming by "Vibroplex" you mean a bug, but you're not really
        specific about it. In any case, one explanation on adjusting a bug is
        here -- <http://www.telegraph-office.com/pages/bug_adjust.html>

        You'll get more answers as time goes on. There is a lot of
        expertise in this group, but traffic is a little slow.

          I believe the Bug Adjusting, Cleaning, version is an incomplete older

            Getting back with some results on the plexiglass
            bug that I built. And by-the-way, thanks to all
            that emailed me with ideas. Very helpful.

            The bottom line......the thing is VERY temperature
            sensitive. The spacing of the dots varies greatly
            with a difference in room temperature. Well, it is
            plastic.....not real metal.....Grin!

            So, looks like it is back to the drawing board.

            I will say, that a plexiglass straight key or a
            plexiglass side-swiper (Cootie key) is easily a
            do-able project, but the plex bug has problems.

            Thanks again for the helpful comments!
