Looking at
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180089590189 what
does the term "Fast Lever" mean?  It's actually printed on the box,
and makes me think it was some kind of option directly from Vibroplex.

          Thanks,

Earl,

I have a US Army Signal Corps bug dated January 1943.  I've never been
able to slow it down below 20 wpm.  When I get enough weight for the
job it stops making dits.  In my humble opinion, it's the length of the
blade that determines the minimum speed at which it will make dits.
And I think if I were to fabricate an extension to the blade it would
operate at something less than 20.

I guess that's not really an answer; it's an opinion.

Hi Earl,
Don't have a clue about the "Fast Lever" terminology.  Looked very  closely
at the lever and didn't notice anything obvious.  Perhaps it has  the Jeweled
cups for lower friction on the pin.  Or something like  that.  Why not give
Betsy a call to see if she can shed some light on  it.

          Well, I called, and asked.

          She said she thought they were just trying to let a buyer
know that it was a fast bug.  I asked if they did anything special
for the "FAST LEVER" designation, and she sounded like she hadn't
heard of that marking before.  So I don't know.

          Thanks all,

Earl,
After reviewing the Vibroplex Original Parts list, I concluded the Fast
Lever just might be the Standard equipped with the Upper Trunion Screw w/jewel
and the Lower Trunion Screw w/jewel.  Each of these would add approximately
$6.00 to the cost of the key, and at least theoretically reduce friction
(increase speed) at higher speeds.  Don't confuse these with the decorative
ornamental red piece that sits on top of the mainframe.

Subject: Taming the swing...

Hi,

I have noticed a swing to my bug sending. Maybe I am worried about
nothing. After all we use bugs to get away from the clinical sound
of perfect code, don't we?

Here is the swing I am encountering. I can transition from a dash to
dot with proper spacing between the elements. But when I transition
from a dot to a dash, I tend to run them together. The dot to dash
transition is still very easily heard by the ear. I use the CWGet
software to graphically view my sending. The letter R is a good case
in point. I can easily send di-dah-dit. However the first dot and
dash are closer together than the dash and the second dot. The dash
to dot transition is always fixed by the bug to matter how I fast or
slow I send the dash and press the dot side. When sending a dot and
moving to a dash, I have attempted to slow down the transition timing
manually, but it can produce a dash too long.

My bug is the Vibroplex Champion # 270463. It does have an Extendadot
device on in. The dit rate is around 17 or 18 wpm. Of course the full
character rate is up to the operator to send a dash 3 times the
length of a dit.

I removed the Extendadot and ran the bug in the low 20s wpm. The
letter R smoothed out quite a bit and became more symetrical. I am
starting to think this a side effect of slowing the bug down. It does
give my sending a distinctive sound. And CWGet can still decode it.
But I can easily send a symetrical R with a straight key at similar
speeds, without any struggle.

So is this common with a slowed down bug? I know this is a very
subjective question as no two bugs are alike. And certainly no two
fists are alike. The best remedy I have found is to slow down my fist
action. I can do this without slowing down the sending. Sending a
period character seems like good practice.

R is not the only letter affected. The letter L is also plauged by
this swing rhythm. Also the letters V, Y, K and more are affected.

Steve, I am so new at this I probably have no business responding. What I notice
more than the space between the dot and dash is the length of my dash is not
very consistent. So that is what gives mine a swing on some letters.

Hi Steve,
                I recently added a Blue Racer to the
   shack and I have a short piece of rigid plastic
   tube which pushes over the end of the shaft
   onto which I attached a small plastic knob
   from a field strength meter that was discarded
   a long time ago. I have noticed the same
   effects as yourself. When sending a "v",
   it tends to send 3 and 1/2 dots unless
   I'm very careful !! Removing the "tamer"
   cleans up the sending again.I've tried
   various ways to slow it down a little but
   everything seems to upset the bug's
   action.I think the answer is to use it as
   Vibroplex intended and just try and
   improve my copying speed!

Steve and Ci,

From what I've heard on the air, neither of you has anything to be  concerned
about.

You will be able to change your fist more to your liking as you  gain
experience on/control over that beast, the bug.  Some degree of  swing is in all
our
fists (whether we admit or not).  You might try  practicing sending words such
as "etc" and "eternally".  Send  them at a speed which allows you to avoid
getting sloppy, keeping the characters  distinct from each other.  These words
help you to gain control by  separating your dots from dashes.  Its not a magic
bullet, but the ultimate  goal is the ability to control the key so its
output sounds "right" to  you.  Also, try some practice sending individual
letters
versus  words.  That way when you send words, you're not stumbling from one
character into another.  I've found the name of the game on the bug is
"control, control, control".
My experience is that the more you practice, the more you will be able  to
make your cw sound the way you want it to.  Right now, your sound is  dictated
to some degree by the key settings.  Just keep at it.  The  sound of your cw is
an extremely personal thing, so only you know what you want  it to sound
like.  Just keep sending and emphasize the "sound" while  avoiding too much
analysis.  Remember the old saying, "paralysis through  analysis".  Hope to work
you
both soon.

The thing that makes your fists sound "right" is you, although a
crappy bug doesn't help matters. The tamest bug out there is a
Lightning Bug and not very expensive either. Additional flat bar
weights are available from VB if you need to slow it down.

I'm not sure I'd worry about it at the moment. A "swing" of some sort
is like handwriting and expresses your personality. Now a really bad
swing with extra dits thrown in gratutitously can be annoying, but I
just smile and go on copying anyway. Nicer to my ears that a
cookie-cutter keyer any day.

Save your money and keep at it.

Hello all fellow Bug ops. What works great for me on my 2 Originals
'51 DeLuxe and '68 Standard and my Blue Racer Standard about '52 is
what I call my "2 Cents Worth Tamer". I find a Alligator Clip that
slides nicely on the Pendelium behind the damper I clip 2 pennies on
the Alligator Clip and face the pennies up and down or sideways to
fine tune the speed a little I find that takes you down a few extra
WPM if someone wants you to QRS a little while sending on a Vibroplex
Bug. You Can also clip the pennies closer or further away from the
damper to fine tune your speed. I hope that helps you It works great
for me.

From my observation across (fifty years) of bug use...

* Additional weights so increase the mass of the pendulum as to make operating
it both different and non-instructive.  during professional use days that simply
wasn't done even for learning.

* adding more weights doesn't slow the bug down much because they wind up being
placed closer to the pendulum.

*  The large diameter weights used by some Mac bugs and E F Johnson have a MUCH
better effect on speed becauseit puts more weight further out on the pendulum.

* Wrapping solder around the wieght at the end of the bug will slow the bug down
much more than adding a second weight.

Unfortunately, the large diameter weights are harder to come by, and the holes
in them don't necessarily fit on vibroplex bugs.

Rather than extensions that add SO much mass and change the feel of the
pendulum, or extra weights that do the same thing with relatively little effect
on speed, I use the recent remake (by Tim Soxman) of the Hills Speed-changer. 
vibroplex sells them under the name, Varispeed.

The Varispeed uses one weight, and the device itself is about the equivalent of
a second weight.  it provides near instant speed changing by rotating the arm. 
It will slow the bug down way slower than second, third, or fourth weights
because by rotating it the small weight can extend the length of the pendulum
which does more than adding weight does.  in so doing it does not add mass like
extra weights or the extension arm.

the Varispeed is the way to go IMHO.  Here is a Varispeed on my (restored) 1918
Vibroplex...



And the very best configuration of all is a Varispeed on the old U-shaped damper
blue Racers, because without the damper in the way, the varispeed and its weight
can rotate straight back and slow the bug down to a crawl.

A few other comments on bug speed...

The slowest American bugs I have encountered are the 1930's vintage Macs.

The slowest bug I have ever encountered, by far, is the Australian Simplex-Auto.
This is a right-angle bug that uses a release mechanism like Coffe's Mecograph
of the early 1900's.  It will go ten wpm, heaven forbid.

Western Union established a fixed speed of 28 wpm.  I have found old bugs with
the weight soldered in place at this speed.

With best wishes,

FD - kt5x

The varispeed, or speed-changer as it was first called,  is shown here on a restored 1918 Original.  The bug had been a ship's key and was hopelessly rusted out.  I decided to restore the base in the style of the ATOZ bugs of the time since I was unlikely to ever see one.  That is why it is green with gold and blue stripes.  I also recreated the decal used on that era Vibroplex bugs
 
 
 
 
I will take a photo of the varispeed on an old Racer, showing how with a U-shaped damper, it can lean straight back.  In that configuration, speed can be reduced into the 12 wpm range!
 
Would people be interested in me writing about mainsprings on various aged (Vibroplex) bugs?

Here the vari-speed is shown on a 1917 Number 4 or Blue Racer.  On Racers with the U-shaped damper, the weight can be directed straight back producing very slow dits.  Unlike an extender, however, the vari-speed is useful even after you master the bug as it provides the quickest and most convenient way to control the speed from as slow as 12 wpm to a great as 50 wpm depending upon whether you use one weight or two, and just how you set up the mountings.  The blue finish on this bug is original, by the way.  The finger pieces are home-made from African Blackwood often mistaken for ebony.  I have the orginal finger pieces, but the wood is more pleasant to touch than the fibrous material used at that time.

This may be the bug capable of the slowest speed.  The Simplex-Auto was made from the early 20's through the forties.  It uses a release mechanism like the Coffe Mecographs.  This produces a very different feel, operation is more deliberate.  The dits run from about 10 wpm to about 28 wpm.
 
The bug was mostly used by the Australian equivalent to Western union, the government postal agency.  When the bugs were no longer being used to send telegrams, about the 1970's, the postal department threw them out, except for a few which operators took as souvenirs.  Those are the survivors still around today.  They seem to sell for between $500 and $750 when you can find one at all.  I traded with an Australian collector.

Fred,

50 years of using bugs!  I will be 50 years on the planet in a few
months, hi hi.

So are you saying the Vari-Speed is better than an Extendadot? In any
case I will be comparing the two within a few days. I ordered the
Vari-Speed based on your comments.

I compared my Extendadot with my original mod and they do feel
different. Just reading  your comments makes me want to try other
ideas while waiting on the Vari-Speed. I have two weights, the 1 oz
and the 0.8 oz. I could bolt them together, side by side, at the end
of the arm to see the difference. Putting both weights directly on
the arm was not a good experience.

I keep wondering about different bugs other than the Champion. The
Champion is supposed to be a low end bug. Is this correct? I need
to look or eBay or eHam.net for other bugs. I was looking at a J-36
on eBay last week and the price really shot up. I prefer to stick
with Vibroplex because of parts.

I just found yet another straight key, the Navy Flame-Proof. This one
is in mint condition and blows away other straight keys rivaling my
Swedish Pump key clone. OK straight keys are off topic. But I like to
brag about a good one.

Now if they would make a nice mini-bug! Bug aren't portable. The Navy
Flame-Proof is small enough to go portable.

Steve,

Will you provide the model number of your Navy flame-proof key?  My
reason for asking is that my CMI 26003A is considered flame-proof by
some folks.  It may be, but I'd sure hate to test it.

with a clamp, the Hi-Mound HK-802, a Swedish Pump key clone, is a
better key. Right now my Flame-Proof is second runner up.

I don't like the knob on the Flame-Proof. I even changed the knob on
my HK-802 to a Vibroplex knob and skirt for their straight key. If I
put that knob and skirt on the Flame-Proof, its ranking might go up
for me. But the threads don't match. My fist is very picky when it
comes to knobs, so I am finding. Its funny, but my arm tires from
sending with the Flame-Proof and other American style straight keys.
But my arm tires from holding it up for the HK-802, not so much from
sending.

I guess that is why we try bugs. I really like straight keys, but am
concluding that no straight key will ever be as comfortable as a bug.
My fist is better with a good straight key. But my Champion is more
more comfortable. With practice my bug fist will improve. Gee now I
need to try other bugs, hi hi.

Hi Steve,

From what I found, quickly, your CJB is a Bunnell key.  You probably
already know that Bunnell was Gen. McCellen't telegrapher during the
Civil War.

He must have had lots of help getting into the key business after the
war.

They had to string lots of wire every night so the General could send
his reports, but I think they relied heavily on WigWag from the hill
tops. But I don't know that as a fact.

My poor old CMI wasn't even in the list.

It's mounted on a chunck of brass 3" x 7" x 1".  It doesn't go
anywhere.  It was on sale at a hamfest about 15 years ago for $45.  I
finally turned my pockets inside out and took it home for $27.50.
It's still my favorite.

I agree with KT5X completely, although I'd like to add one correction
and a comment.

The "FYO" paddle and Vari-Speed were invented by Joseph A. Hills
(W8FYO) of Dayton, Ohio - I remember the FYO key being offered for
sale in the early 1960s and I remember seeing one at Vernon, CT at a
FOC meeting in the late 1970s.

Joe's patent on the FYO was later licensed to Bencher.  (At least this
is what I remember).  Around 1980, HAMCO from California introduced a
variation on the FYO key using dual levers and pin support of the
movement plates which were coupled to finger pieces (paddles).  Peter
Garsoe, owner of Vibroplex, bought out the rights of the HAMCO paddle
in the early 1980s.  Vibroplex introduced the "Brass Racer" which was
a exact copy of the HAMCO paddles.

Patent number: 3166638
Filing date: Jan 30, 1962
Issue date: Jan 19, 1965
Inventor: Joseph A. Hills

Hills device that showed down the semi-automatic key was called a
"Varispeed" by him - he may have had an earlier name.

I do not see a patent issued to Hills for the varispeed.

WU and Tropical Radio Telegraph (radio) and others had time/motion
studies done for telegraphers.

The optimum speed for radiotelegraphy was found by Tropical Radio
Telegraph, later and currently traded under the name of TRT was found
to be 27 wpm.

Western Union (WU) being a company that used American Morse instead of
International Morse (radio code) used a code which was faster than the
International Morse Code.  Thus I assume Fred KT5X has measured the
radio speed of these bugs with the fixed weights.  He says he measured
28 wpm.  This speed would have been greater in words per minute in
American Morse.

(I'm not trying to nit pick, Fred.)

I would assume that the optimum traffic speed for telegraphy would
have been approximately the same for wire and radio - I know based on
conversations with Normal Richardson of TRT (Slidell, LA) and others
that TRT did multiple tests on this at 27 wpm and found that even an
increase to 28 wpm would cause the revenues of the circuits to become
lower as more time was required for repeats that cancelled out the
speed increase.

It was interesting that the operator who consistently was the #1
revenue producer for TRT at Slidell Radio / WNU was Frank Estrada, his
sine was FE and he sent only with a straight key - 18 to 20 wpm.  He
came well ahead of everyone else in traffic count and revenue.  No one
else was even close.

Kind of like the tortoise and the hare - fast isn't always the most efficient.

Scott,

The Navy Flameproof key is probably the best key for the money anywhere.

I believe I must have told you so during one of our telephone conversations.  If I didn't I should have.

I smoothed out the knob on the flameproof so it doesn't irritate my fingers.

Screw that key down and you can REALLY send.

Why?  Because you can pull and push with that type of knob.  It's faster.

If you're interested in a tiny bug, look for K4VIZ on the internet - he makes a miniature bug.  You don't get a good speed range - because of the limited pendulum.

Fred,

50 years of using bugs! I will be 50 years on the planet in a few
months, hi hi.

So are you saying the Vari-Speed is better than an Extendadot? In any
case I will be comparing the two within a few days. I ordered the
Vari-Speed based on your comments.

I compared my Extendadot with my original mod and they do feel
different. Just reading your comments makes me want to try other
ideas while waiting on the Vari-Speed. I have two weights, the 1 oz
and the 0.8 oz. I could bolt them together, side by side, at the end
of the arm to see the difference. Putting both weights directly on
the arm was not a good experience.

I keep wondering about different bugs other than the Champion. The
Champion is supposed to be a low end bug. Is this correct? I need
to look or eBay or eHam.net for other bugs. I was looking at a J-36
on eBay last week and the price really shot up. I prefer to stick
with Vibroplex because of parts.

I just found yet another straight key, the Navy Flame-Proof. This one
is in mint condition and blows away other straight keys rivaling my
Swedish Pump key clone. OK straight keys are off topic. But I like to
brag about a good one.

Now if they would make a nice mini-bug! Bug aren't portable. The Navy
Flame-Proof is small enough to go portable.

DR knows of what he speaks when saying that Hills was the first to introduce the varispeed.  I think that was about 1951.
 
And I did not measure the speed of the dits of the bug with the weight soldered to it, only estimated it, and certainly would be most fortunate if my estimate came within a mere 1 wpm, hi.
 
To steve, yes, I think the varispeed is better for slowing a bug down, and for just plain using a bug than the pendulum extension.
 
but i don't share your enthusiasm for a straight key.  Please do have at it, but for me, Morse becomes laborious below about 25 wpm because it loses its language characteristic and returns to being a cipher.  Since I can't make 25 wpm Cw with a straight key for more than a few minutes, it is a bug and a pddle for me.
 
DR, I coveted the original FYO paddle when I was a youngster, so much so, that I made my own rendition of it.  my rendition, from the 1963 QST article, was a dual lever, and possibly the first dual lever version of the FYO's idea, I don't know.  It was 1963 well before Bencher, and before FYO produced the paddle.  I still have that paddle, and other than being light because I built it on a walnut base, it works very well.
 
 
 
The wood was cut by hand.  The levers were hand cut with a hacksaw, and bent in a vise.  The contact posts borrowed from a J-36.  The pins supporting the levers are nails filed to a point.  The ratio from pivot to contact versus pivot to finger piece is 1.5:1 such that the gap is made to feel smaller than it really is.  The key can be adjusted to where you can not feel it move.

          I don't know if this particular Varispeed is an old one or
not, but I've noticed that you can now get a Varispeed for a flat
pendulum directly from Vibroplex.
