      If using a vintage bug for CW work,  heres one to try,  copy the original
      set up in a telegraph station,  mount a straight key of that vinatge for
      your pumper,  it will have the strip contact on it already that the bug
      plugs into,   then equip each bug with the cord and wedge that was
      used with it originally,  just slide the bug over and plug it into the
      straight keys contact.   Probably many dont know that is why the
      contact strip is on the top of the straight key in the first place. 
      If you were a telegrapher of CW op of that era you furnished your
      own key,  and most took it home every day in a case,  when you
      got to work you just plugged into the existing furnished straight
      key and away you went.  
      I do it for grins to preserve the nostalgia of the bugs,   bugs were
      telegraph instruments mainly. 
      Or for real fun hook up a telegraph sounder to the audio of your
      radio and copy the CW from the sounder,  be sure and use a
      tobacco can to amplify the clicks and impart the real sound of
      telegraph. 
      Sorry guess that shows my age to remember seeing and hearing
      the real thing.  73 Merv K9FD
      Sometimes things seem so obvious AFTER one thinks of it, hi hi!
       
      I mount a jack on a little piece of perfboard on each key, then changing keys is as easy as plug-in.  I have thought of two easy ways for jack mounting.  One is a small piece of perfbaord with two holes the distance apart of the binding posts.  The other, that I haven't done yet, but will with my next restoration project, is one that mounts to the two screws that hold the damper, such that the jack is against the back of the base.

      Cool beans, Fred.  I've been using a cap on each bug (and switching around since I don't have enough caps).  I'm gonna implement that one (sp?) right away.

                    = 100000 x 10^-12 F
                    = 10^-7 F
                    = 10^-1 x 10^-6 F

                        Hello to all...

                        Respectfully...

                        Frank, W7IS does in fact sell the extendadot system and has been for several years.

                        I have been using his system on several of my faster bugs for some time now and I'm very satisfied with the materials, design and performance of his product.

                        As I understand it, no one specifically asked him to build a device for the masses but he took it upon himself to do just that. The extendadot is a refreshingly simple yet well thought out design.

                        I for one, have no issue re-adjusting a bug and can accomplish this feat in under a minute. Adding the extendadot arm and subsequent adjustments, was/were no problem for me.

                        I also believe removing one side of the tube not only ruined the original design but likely created a "hack" look that I would certainly never display to anyone. I think I would be embarrased to show something like that publicly. If one had run it through a C&C machine and could produce your enhanced design over an over again, then maybe one might would consider it not a "hack".

                        Mr. Mass, I would like to think that Frank will respect your opinion as to his designs but, don't be surprised if he doesn't send you another example to critique. Then again, with Frank, maybe he'd send you another because that's the type of gentleman he is.

                        Well... that should get the "group" going again I'd say!

                        Again, respectfully...

                        Bob

                          I've yet to see any of Freds craftsmanship that looks remotely hacked.

                          I share Freds annoyance with the amount of adjustment to the key that putting on/taking off an extendadot or similar devices that move the pendulum towards the dot contact.


                          His modification appears to be very worthwhile.


                          Regards

                          Hello to all...

                          Respectfully...

                          Frank, W7IS does in fact sell the extendadot system and has been for several years.

                          I have been using his system on several of my faster bugs for some time now and I'm very satisfied with the materials, design and performance of his product.

                          As I understand it, no one specifically asked him to build a device for the masses but he took it upon himself to do just that. The extendadot is a refreshingly simple yet well thought out design.

                          I for one, have no issue re-adjusting a bug and can accomplish this feat in under a minute. Adding the extendadot arm and subsequent adjustments, was/were no problem for me.

                          I also believe removing one side of the tube not only ruined the original design but likely created a "hack" look that I would certainly never display to anyone. I think I would be embarrased to show something like that publicly. If one had run it through a C&C machine and could produce your enhanced design over an over again, then maybe one might would consider it not a "hack".

                          Mr. Mass, I would like to think that Frank will respect your opinion as to his designs but, don't be surprised if he doesn't send you another example to critique. Then again, with Frank, maybe he'd send you another because that's the type of gentleman he is.

                          Well... that should get the "group" going again I'd say!

                          Again, respectfully...

                            Respectfully,
                            It seems to me Fred has found a way to make a good thing even better, and much easier to use and remove without extra adjustments.  Many times, the first prototype of a maching/tool has somewhat of a "hack" look, to be refined in the finished product.  That is not a negative thing.  If the product works better, I think its a cause for celebration. 
                            Congratulations to Frank for his super idea, and to Fred for a refinement that makes that idea even better.  Now, on to the polishers and finishers for that "showroom" look.

I decided to modify the device. I put it lengthwise into a vise (maybe it's a vice, but I digress), and filed away one side of the tube, such that when installed, the damper wheel can rest against the lever itself, not the tube.

In fact, with one small weight up near the vibrator, and one small (aluminum) weight at the far end, most of my bugs will slow to 15 wpm or speed to 40 wpm, varies by bug, but typical. I can hardly expect that isn't a good range for almost anyone.

The bug shown, not much is visible in the close-up, is a 1910 Double-Lever. But the bugs I LOVE it on are the Racers and the Juniors which have shorter levers on which to locate weights, and are thus typically, a bit fast.

One capacitor on the bug cable takes care of all bugs, no need to mount a cap on each bug.

I think I would be embarrased to show something like that publicly. If one had run it through a C&C machine and could produce your enhanced design over an over again, then maybe one might would consider it not a "hack".

(Not that it isn't a great idea that works, but I am rarely satisfied with anything as it arrives ;-) The bug had to be completely readjusted to put it on or off. When in use, the whole lever was canted to the side because of the thickness of the barrel of the extenda-dot between the lever and the damper.

I decided to modify the device. I put it lengthwise into a vise (maybe it's a vice, but I digress), and filed away one side of the tube, such that when installed, the damper wheel can rest against the lever itself, not the tube.
