      Meir,

      I happen to respect your taste in keys - especially straight keys -
      those you love are the same as I love!

      I agree with you on the coffin bugs. In addition, I always found them
      terribly difficult to adjust to sound sweet.

      Regarding Vibroplex, I have to say that I prefer those made in the
      1940s vintage - they play very well. Second to that, their bugs up
      until about 1970 seem to be very good. I would assume that the
      decline in wire telegraphy that saw the good fortunes of J.H. Bunnell
      and Vibroplex caused concern at Vibroplex and that concern was
      evidenced by declining quality of their instruments. The Albright
      family who had owned the company for many years, probably saw their
      fortunes were going to change, and sold the company to John LaHiff
      their long time mechanical engineer about 1965, then John passed away
      and his family sold the company to Peter Garsoe an investor (non
      telegrapher) about 1979. I believe Bunnell whose keys and sounders,
      peg boards, etc. were the main stay of telegraph stations in North and
      South America had little or no "radio" market and closed its doors -
      yet the corporation remains to sell parts and a re-issue of their tiny
      key on board which had been given as a commemerative gift of
      recognition for years.

      With Peter Garsoe the new owner of Vibroplex came changes - the LaHiff
      mainspring was taken out of the Presentation, the trunnion height
      adjustment on the main lever was discontinued which makes re-adjusting
      to make the contacts align more difficult - although it can be done
      with the bottom trunnion screw for a small amount and if not, a rubber
      mallet and vice to move the pressure fitted main lever.

      Why the reason in quality? I supose it is because of the way the keys
      play. I trace most of the problem to the new practice of plating the
      mainspring. This makes the swing stiffer which makes the energy in
      the swing lesser, and the speed of the swing higher.

      So Meir, what is your favorite bug?

      I like my 1940-45 Vibroplex (and perhaps older), my 1940s McElroy bugs
      best. Second place are the Vibroplex bugs up to the 1970s.

        David,

        The Vibroplex Deluxe Original I got in 1969 - used, a couple of years old
        then - is still with me and used regularly. I also have (all post WW2 with
        the NY address) a black and a gray Lighning Bug and a black Original. I
        also have a Lionel J-36 military bug. It's about the same in action and
        the level of my preference as the Vibroplex bunch.
        Then came the Telegraph Apparatus "hole in the wall" bug about a year ago
        or so, and immediately it became the number one key in my preference.
        As you know, McElroy was involved with that company, so it's still a
        McElroy key... I'd like to add a McElroy brand key to my collection
        eventually.
        A few months ago I bought a Speed-X bug at a hamfest, and i fell in love
        with it... It has an incredible speed range without any external gadgets.
        So now I have the TAC key set for high speed (it's much better at high
        speeds and smoother than the Vibroplexes), and the Speed-X set for low
        speed at my main "modern" operating position.
        My WW2 vintage US Navy station (RBB-2, RBC-2 and RAL-6 receivers, TCM-2
        transmitter) is set up with the J-36 key.
        The 1944 vintage Victory ship radio console (Federal FT102 with the MacKay
        167-BY transmitter and the RMCA AR-8506B receiver has the original MacKay
        key mounted on it.
        I try to keep the key types in line with the vintage and model of my
        vintage radios...

          I agree with what you say 100%.  I believe (haven't measured them) that the Telegraph Apparatus Company (TACo) bugs built by McElroy in Chicago and the Speed-X bugs have a larger vibrator.

          In any case, I agree they send better.  If I had to have one bug, it probably would be the chromed "hole in the wall" bug by TACo as I like the chrome!

          Those bugs have a big hole in the base - probably for a big bolt to hold them down!  Thus the name.

          I have a McElroy "Teardrop bug" model S600 which has a wide speed range and is a ballerina at 50 wpm.  It handles divinely at high speeds as most (if not all) McElroy bugs do.  I love the art deco design and I also like the McElroy Deluxe bug of 1939 with the Marbelite finish - a good sender, but the Teardrop bug is better or at least wears better makeup and has much better curves.  (;-0)

            David,

            My TACo bug mechanism pivot support is chrome with black base. I think
            it's called "hole in the wall" because the arm support pivot is in a block
            with a big round hole as opposed to the bridge or arch like structure a la
            McElroy and Vibroplex...

            The teardrop McElroy is cool looking! I like the old T handle McElroy looks.

            Talking about the teardrop - a friend of mine got an Eddystone teardrop
            bug recently. It is really Art Deco!

              Wow David!

              I find my coffin bug to be very easy to adjust.

              That said, I've kind of torn betweent the coffin bug and my 1953
              Presentation. The latter really does feel smooth. I am thinking of
              putting the Vibroplex conversion paddles on my Presentation. The lesson
              I've learned from the coffin bug is that prefer two fingers pieces,
              rather than the one finger piece and knob of the Vibroplex bugs.

                    I'll keep that in mind, Milt. At my sub-light speeds, it has the
                    opposite effect.

                      Mine seems very small and the bug is real fast. I expected it to be
                      much slower than my AnnieBug, but its faster.

                      There is much more to the speed adjustment that just the weight on the vibrator. The distance the pendulum has to cover also has a great effect. 73 David N1EA

                          Thanks guys, but I am not looking for more weight or to slow mine down. I just want to know if these bugs and the varieties came with only 1 size weight.

                            Bill, I believe these bugs came with only one weight. I believe all bugs that had square weights came with one weight. The exceptions were the round weight

                              Bill,

                              I believe these bugs came with only one weight. I believe all bugs
                              that had square weights came with one weight. The exceptions were the
                              round weight models of Vibroplex and McElroy - they were supplied with
                              TWO small round weights for greater speed range.

                              I suspect - if your bug runs too fast, that it is adjusted as a new
                              bug user who is used to electronic keyers and paddles might, or that
                              the operator who owned it was a real QRQ operator.

                              You haven't specified a slow speed for the pendulum, so I am guessing
                              that you are trying to say the bug won't slow down to 16 wpm or so
                              which was the typical low range of those coffin bugs.

                              First check the mainspring of the bug - it should be around 0.013 to
                              0.017 inches thick. Thicker mainsprings send with less vigor and send
                              slower.at "normal" spacing bug because they don't have vigor, the
                              operator is forced to make the travel of the lever less, which
                              increases the speed of the pendulum.

                              A bug with a 0.013 mainspring will have a lot of vigor and a great speed range.

                              If you find the mainspring is 0.017 or greater, inspect for signs that
                              the spring has been replaced by a hack machinest who didn't understand
                              that he needed the correct spring to have the bug work. It has
                              happened to me frequently.

                              If the key is old and a bit dirty I advise owners to do the next
                              paragraph - because the coffin bug is enclosed this probably isn't
                              needed.

                              I tell people when they get a new bug to completely disassemble it -
                              and make a mechanical drawing of it as they go. It is easy to miss
                              washers, so look well and try to move washers from posts as they often
                              stick. Often a new user puts the insulating washers on the wrong side
                              and the bug won't work.

                              Polish silver contacts with very fine rouge paper until bright. There
                              are four contacts on a bug.

                              Clean, degrease, with ammonia all parts with detergent, then clear
                              water rinse. Put all parts on paper towels and into an old toaster
                              oven set at 140 degrees for three hours to dry.

                              As the Coffin bug also has a race of ball bearings, this would be time
                              consuming - so just skip to adjustment.

                              Adjustment - loosen up bug completely, set pivot of trunnion so that
                              it doesn't wobble but doesn't bind, then adjust damper set limit
                              adjustment for proper action. Adjust "downward" all adjustments until
                              the vibrator starts to loose its vigor, then back up untill it still
                              has vigor.

                              There are files in the "Files" section of this group - about bug
                              adjustment and cleaning.

                              73

                                Interesting--I also also have a TACO CP-510, a SPEED-X 501, a "Coffin
                                key" (HI-MOUND BK-100 design), a Lionel J-36, and of course several
                                Vibroplexes, mostly 50s vintage. I agree, The TACO hole in the wall
                                key is the best, as it has a solid, snappy, smooth feel to it. The
                                'Coffin' has a kind of plastic feel to it and the clattering noise it
                                makes is really annoying. Any way to deaden that noise? I also have
                                trouble dealing with the paddle which is actually like the SPEED-X
                                (flat, no knob). I actually ended up putting a straight key knob on
                                the left side of the paddle of the SPEED-X, I hope this doesn't offend
                                any purists....The SPEED-X is also really fun to use.
