For my home made bug tamer. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. I really would have liked another quarter inch of adjustment to allow closer spacing of the dit contacts. You can wrap solder around the ears of the clothespin to add more weight and slow those dits down to match your dahs! I would have to use a washer or something like it in order to regain the adjustablity of dit tension. You had to do a sending test back then. In short order you can learn to send.

My initial version was set up with all the weights at the end of the tube farthest away from the pivot. The Vibroplex was based on a lever that rotated around a vertical pivot. I truly believe that in order to be a good bug op one has to have a solid understanding of the mechanics of the bug key. The trick is to get your reading skill down for higher speeds as people assume you are capable of receiving real fast when they hear your bug.
As a mechanical guy, the entire design and operation of the Vibroplex has fascinated me since I was first licensed. For the Vibroplex bug tamer, you slip it on and tighten a set screw. There are keys out there called sideswipers and that is exactly their purpose in life. My original elmer busted my chops for lousy spacing from the get-go, forcing me to clean up my sending. Buying one supports this channel. That is what I was trying to duplicate using cheap and available hardware. Upright: Also called the Wire chiefs Key, this model featured a horizontal knob and thumb piece with a right-angle mechanism so that the lever arm and contacts were all vertical.
The quality and pride of ownership of a Vibroplex Bug cannot be matched. None were built after 1939. I set it up on the operating desk and connected it in line with my other keys. I always enjoyed using a straight key, and I knew a guy who could make a straight key sound like he was using a bug, he was that fast and good. It's amazing to hear so many straight keys and bugs just about any time of day or night now. The locking collars in turn slide onto the diameter of the brass tube and are held in place by their set screws.
Just put a link to your design in the comments below. However I ended up with a paddle, the one in my avatar. Instruments offered as Deluxes post-1940 Original, Blue Racer, Lightning Bug Some notes on Horace G. This tiny, nickel-plated piece of handiwork was truly pocket-sized and featured a small, articulated rear leg that could be swung out for stability. The silver weights are steel shaft collars with a set screw that locks down the collar in place. Then, out of the corner of my eye I caught the sparkle of chrome.
I found a piece of brass tubing that fit over the round steel pendulum arm. I used to help teach code at licensing classes. The idea of modifying an alligator clip and hooking it on the end of the arm was very good. I just happen to use an iambic paddle to do the same thing. Sam, you can use either kind of paddle, the dah side of a bug, or even a straight key mounted sideways. I found one reference, though, that said McElroy preferred that the hand and elbow should be raised above the desk so that the operator can use a free swinging arm motion! Junior: The Junior was nothing but a set of Original parts mounted on a slightly smaller 6 x 3 base. After a couple of days tinkering around and searching, I found that the tab end of a picture frame hanger would work very well for my needs.
I have used a Vibrokeyer for going on 4 decades and have never really learned how to use a set of iambic paddles correctly i. New: A brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Someday I'll buy a proper set of weights. I was heading for a vendor that I usually visit and who normally has some radio gear. The Bug is designed for code speeds ranging from about 20 wpm on the low side to 50+ wpm on the high side. I think the question here is that Sam wants to send manually - without electronic intervention - but just with less glass arm than he gets with the straight key. By 1904 Martin had come up with a different design that used a side-to-side vibrating arm to form the dots, and Martin named his new invention the Vibroplex.
The Vibroplex is a wonderful mechanism and makes a great test bed for tinkering if one is so inclined. The result is a 3-turn spring that provides a very light touch. Smooth, jeweled movements for precise control. After 6 months using the key on the air I have become confident in my sending with the bug and have received several compliments on my good bug fist. By contrast the traditional straight key familiar to most as seen in movies and tv produces speeds ranging from 5 wpm to 20 wpm or a little faster if the operator is highly skilled. In spite of the practice, I still goofed up a bit, when I was on the air especially when I was tired, and my concentration wasn't the greatest.
The downside is that it requires more depth on the operating table where the extra length won't bump into anything. Post-1979 Vibroplexes have used a variety of paints including textured gray, powdered black, etc. Martin also developed a Rotoplex in the early 1940s that featured a rotary pivot mechanism, but that was his last known invention and only a few were ever made. As far as is known, the Midget was only built from about 1918 until 1920. Cost is about two cents, and the adjustment is precise and adjustable from no additional weighting to a lot, depending on how many wraps of solder you use. In my case even after one year of using Morse Code my copy speed was not up to even the slowest speeds of the Vibroplex.
