  Thanks for the insights regarding bugs and pendulums and vibrating arms. I
  was imagining that the forces of the arm and contact springs were taking the
  place of gravity in this horizontal situation, but that the idea of the
  pendulum still applied. The bug I modified as a kid had a scale stamped into
  the bar showing the speed for various positions of the weight, and it was
  marked slower the farther the weight as positioned out from the pivot, thus
  my assumption that it was indeed like a pendulum and it wanted a longer level
  arm to go slower. And when I extended the arm it indeed went slower.

  Adding weight did slow it, but a lot of weight was required to only reduce
  speed a little bit, thus my conclusion that the dominant factor was length
  rather than mass. I also noted a lengthening of the dits with added weight,
  which was reinforced in my mind when I saw the idea of "weight" adjustments
  on electronic keyers. Apparently I built a whole system of fake-physics in my
  head to explain my observations.

  Thank you.
