9805 SIMPLE HOMEMADE KEY AND SOUNDER PROJECT:(17KB)
This project is designed to introduce children to the principles of
the electric telegraph.
It uses readily available parts:(12KB)
2 Pieces of wood.
8 small screws.
2 large nails.
4 flat strips of metal. (One MUST be iron-bearing or "ferrous" metal).
20 feet of INSULATED wire from 18-28 guage (around 1/32 inch diameter).
2 flashlight batteries.
The Key:(14KB) consists of a strip of metal
which can be pressed down to make contact with a screw.
The battery holder:(14KB) holds the flashlight
batteries and makes electrical connection with each battery.
The Sounder:(12KB) consists of about 100 turns
of wire wrapped around a nail which attracts the iron-bearing strip
of metal and makes a clicking sound. When the sounder is deactivated,
the metal springs upward, striking another nail and making a second clicking
sound. Dots and dashes can be distinguished from each other by
learning to tell the difference between the pull-in click, and the
release-click.
For more details see: How to
build a simple telegraph set. which is in the "general
information" part of this museum.
9806 ANOTHER VERSION OF THE ABOVE PRACTICE SET:(24KB)
This set was built by 13 year-old Claire Berry in KwaZulu, Natal, South Africa.
It earned a high grade in a science project.
9806a ANOTHER VERSION OF THE ABOVE PRACTICE
SET:(29KB)
9806b CLOSEUP VIEW OF SOUNDER ON ABOVE SET:(34KB)
9806c Here is a third version of the above
set:(37KB)
9806d DO NOT MAKE A TELEGRAPH SET LIKE THIS ONE !!!
The young builder has made the set with wire that has NO INSULATION on it.
Each turn of the coil short-circuits to every other turn on the coil so the
magnet does not work at all. Please use WELL INSULATED WIRE when you wind the
coil.
9807 Here is an excellent Telegraph Science Project built by 5th.

9810 EARLY HAND MADE WOODEN KEY AND SOUNDER:(24KB)
This early key and sounder were probably built from one of the many
sets of plans in children's books and magazines in the early 1900s.
9811 EARLY HAND MADE WOODEN SOUNDER:(12KB)
A nicely constructed wooden sounder probably made from plans
that were included in many magazines in the early 1900's.
9812 HAND MADE WOODEN SOUNDER:(28KB)
A very simply constructed wooden sounder probably made from plans
that were included in many magazines in the early 1900's.
9818 SUB-MINIATURE KEY MADE IN ROUMANIA:(27KB)
This tiny key was found at the huge hamfest at Friedrichshaven,
Germany in 1996. It was made by a roumanian student.
9820 * HOMEMADE STRAIGHT KEY:(35KB)
This beautifully designed and machined straight key was obviously
made by an expert machinist. It has a brass base with polished
steel and brass hardware, ball bearings, and machined white
plastic knobs.
9821 * HOMEMADE STRAIGHT KEY:(14KB)
This key is not very well made but it has a nice ''feel''.
9823d INTERESTING OLD HOMEMADE CAMELBACK KEY AND SOUNDER
ON BASE:(88KB)This camelback key and sounder set has been polished
so that it looks new. The other pictures show it in the as-found
condition. The key and sounder look very similar to those on the
well-known Bunnell camelback KOB sets. The total lack
of knurling on all of the adjusting screw heads and the rather sharp
edges on the machined parts suggest strongly that the set was homemade.
When you look at the bottom of the base you see that none of the
screws that hold the set to the wood were tapped and that a very
unusual technique has been used to hold the key and sounder to the base.
The set was found by Civil War Insulator Collector Phil Hill who
has allowed me to display his photographs of it.
9824 EXTRAORDINARY ELABORATE HOMEMADE CAMELBACK
KEYS:(10KB)These two keys look elaborate enough to belong in the
1840's era.
9825 MINIATURE HOMEMADE CAMELBACK KEY:(8KB)
This tiny and lovely 2" long brass camelback key was made
by a very well known key collector.
9826 * GERMAN-MADE MINIATURE CAMELBACK KEY:(16KB)
This tiny and lovely brass camelback key was made in Germany in 1998.
9828 * ODD BUNNELL TRIUMPH KEY MODIFIED BY THE
ADDITION OF A SOUNDER FRAME:(20KB) It is unclear why the owner
of this key decided to add a sounder frame to the top of the
key.
9829 * HOMEMADE BRASS IAMBIC PADDLE:(10KB)
This is a carefully designed brass iambic paddle pehaps patterned
after a Brown Brothers design. It has a fairly crisp
action.
9830 * HOMEMADE PADDLE:(14KB)
This is a carefully made but poorly designed brass paddle with some
polished steel hardware. Interesting design. Does not work very well.
9831 THE FAMOUS QST J-38 PADDLE:(15KB)
Many hundreds of these iambic paddles were made by hams after
an article in the July, 1952 issue of
QST described the basic design. The paddle is made
by simply screwing together two J-38 straight keys and mounting
the resulting mechanism vertically. This ugly paddle has
a surprisingly good, crisp, light, ''feel'' and compares
very favorably to a well adjusted Bencher paddle.
9832 * UGLY UGLY UGLY HOMEMADE BUG:(16KB)
This is one of the ugliest homemade keys that I have seen
but it does function....sort-of.
9833 * UGLY UGLY UGLY HOMEMADE PADDLE MADE FROM
A SAW BLADE:(16KB)This key was spotted but not acquired at
the Rochester Hamfest in 2002.
9835 UNIQUE MINIATURE ADD-ON BUG FOR STRAIGHT KEY:(36KB)
This tiny bug measures just 1-1/2x3-7/8 inches. It was designed to
slip over the knob of a straight key and pivot on its bracket.
It can also be moved up and down to act as the straight key's knob as you can
see in the following pictures. The bug has a very crisp and smooth action
which is unusual in a bug as small as this. 9836 ** THE 'MONOVERT' SEMIAUTOMATIC TELEGRAPH SPEED
KEY Designed and built by W. R. Smith (W4PAL), 2004 The Monovert speed
key stands 7-1/2" tall, weighs 3-1/8 pounds, has a speed range of 13 to 38 WPM
and has one arbor. The base is of 3/16" chrome plated brass and the foot is 1"
thick chrome plated brass. The height was shortened by folding the dash bar
above the arbor. This was made possible by passing the dot bar stop screw
through a hole in the dash bar. I appear to be the first designer to do this.
The key has a very smooth action. This is likely the first new vertical speed
key design in about 80 years. 9836g ** THE 'MAGNEVERT' SEMIAUTOMATIC TELEGRAPH SPEED
KEY/PADDLE Designed and built by W. R. Smith (W4PAL), 2005 The Magnevert
speed key stands 7-3/4" tall, weighs 4-1/2 pounds, has a speed range of 15 to
35 WPM and has two arbors. The pendulum is supported on two 3/16" OD ball
bearings, contains no mainspring and depends on the repulsive force of four
rare earth magnets for its vibrations. Dashes are made in the conventional way
but dots are made by a fifth rare earth magnet under the pendulum passing over
a reed switch mounted in a small brass tube. The damper rotates outward to
allow weight changes. By locking the pendulum with the stop opposite the
damper, the key becomes a paddle for keying an electronic keyer. This is
likely the first vertical speed key to use permanent magnets instead of a
mainspring. 9837 ** THE 'DUOVERT' KEY: THE FIRST FULLY-AUTOMATIC
VERTICAL BUG:(22KB) The Duovert key was designed and built by William R.
Smith W4PAL in 2004. It is the world's first fully-automatic (both dots and
dashes are made automatically) mechanical single-arbor speed key. It is 8
inches high and has a speed range from 15 to 35 WPM. The short height and
single arbor are made possible by a through-the-dash-bar stop for the dot bar
which has never been used in keys before. A magnet and reed switch operated
by the dash lever can make up to 40 dashes. Speed adjustment is by moving
weights only.
9838 ** THE SUB-SUB-MINIATURE STRAIGHT KEY: "THE NANOKEY"
MADE BY W.R.SMITH, W4PAL: W.R. Smith is a world renowned watchmaker and a
Radio Amateur. In 2006, he decided to apply his skills to making perhaps
the world's smallest and most carefully machined straight key.
9839 ** THE SUB-SUB-MINIATURE RIGHT ANGLE
BUG: "THE MINIKEY" MADE BY W.R.SMITH, W4PAL:
WR decided to make a tiny right-angle bug with several unique features that
have never been included in a key before. His technique of passing the dot
bar stop screw through a hole in the dash bar allowed him to make this key as
small as it is. The key measures only 1-7/8" long by 5/16" wide ! The
contacts are silver. Each screw post has been treated so it grips the
adjusting screws thus eliminating the need for lock nuts. A finger pad on the
ornate hand-turned post allows the operator to place a finger on the key to
hold it in position while sending. The key has a signet paddle and the two
posts in the upper right hand corner are the terminal posts. The speed range
is 18 to 25 wpm.
9840 ** TINY HAND-MADE MODEL OF VIBROPLEX MIDGET:(12KB)
This tiny key was made by David Hale who took all the measurements from
a full size Midget and dupicated it in miniature in virtually every detail.
The following pictures show different views of the key and a picture of
David Hale.
9841 ** TINY HAND-MADE 1/2 Scale WORKING MINIATURE
MELEHAN VALIANT FULLY AUTOMATIC BUGS:(24KB) This is the most
complex and ambitious project that I can imagine. Master machinist
David Hale, W1KR obtained the original patent drawings for the
magnificent Melehan Valiant full-automatic telegraph key from
Randy Cole. In addition, he personally measured every dimension
of my Melehan Valiant so that his 1/2 scale miniatures would be
correct in every detail. The pictures listed under 9842 show the
stages of construction of the bugs and the following pictures
display the final product.
9842c ** EARLY LOOKS AT THE UNFINISHED PAIR OF
MINIATURE MELEHAN VALIANT BUGS:(24KB) This is the most complex and
ambitious project that I can imagine. David Hale, W1KR obtained
the original patent drawings for the magnificent Melehan Valiant
full-automatic telegraph key from Randy Cole. In addition, he
measured every detail of my Melehan
so that his 1/2 scale miniatures would be correct in every
detail. This view shows the two completed base assemblies
placed behind boxes of the tiny screws and parts. He has
even precisely duplicated the knurling on each screw.
9843 ** A KEY-BUILDING FATHER AND SON
AND A 'BIG' KEY:(18KB)
David Hale, W1KR, made this oversize key for his son Max to play with...
perhaps in hopes that it would stimulate his interest in CW.
It was used in the "Left Foot Contest" in 1994. He built the key
as a scaled-up version of a J-38. It is made of 3/4" plywood.
The adjustable parts are carriage bolts and t-nuts with plywood knobs
made with a hole saw. The contacts are made of copper pennies. The
key now hangs on the wall of the Barre (VT) Town Elementary School.
If anyone would like more information on how to build a key like this
you may contact David Hale at [email protected]
9844 ** EARLY LOOKS AT THE UNFINISHED PAIR OF
MINIATURE VIBROPLEX VERTICAL BUGS:(20KB) The Vibroplex
vertical or 'upright' key is one of the most sought-after
collectible keys. David Hale - W1KR is currently working
on building miniature versions of two of these complex keys.
The following pictures
show some of the parts and some of the machine tools which
he made to facilitate his project.
9847 ** HOMEMADE MELEHAN VALIANT WORK-ALIKE KEY:(53KB)
This key was built by an unknown person and designed to make automatic
dots AND dashes in a manner similar to that used by the Melehan Valiant.
I am including many views of the key to help clarify its design.
9849 * HAND MADE COPIES OF FAMOUS VIBROPLEX KEYS
BY MARTIN ODENBACH - DK4XL: THE VIBROPLEX VERTICAL:(16KB)
Martin Odenbach - DK4XL is an expert machinist and he has made some
very accurate reproductions of the rarest Vibroplex keys. As
you can see below, his workmanship is superb. He travelled
widely to visit major key collectors and made accurate
measurements and drawings of their keys before beginning
work on his keys.
9850 * JJ-38 JAPANESE COPY OF A J-38
WORLD WAR II UNITED STATES MILITARY KEY:(21KB)
At first glance, this key appears to be a standard World War II
vintage J-38 United States Military Key. However, it is marked
JJ-38 and the key mechanism is the familiar imported Japanese design with
the ball-bearings at the end of the trunnion that has been
widely distributed in this country since the 1960's.

9857 CRYSTAL RADIO RECEIVER MADE FROM SIGNAL ELECTRIC
COMPANY TELEGRAPH KEY PARTS:(36KB)This unusual crystal radio
receiver was made using signal electric telegraph company
shorting switch levers for all of its conductors. It uses the
classic ''cat's whiskers'' detector with a small crystal acting
as a diode to detect the AM broadcast signals. The crystal is
adjusted by moving the copper cat's whisker wire to a 'hot'
place on the surface of the crystal. The label says that
it is an EAM Toy.
