•The wooden peg mandolin device might be the Cremona style. The Cremona mandolin attachment consisted of a wooden tray that is mounted just below the hammer line. For each note there is a thin wedge of wood (usually maple) that is spring loaded and just long enough to fit between the shank and the s...

•This roll-playing device was made by the Smith Lyraphone Company of Baltimore, Maryland, USA. The interesting thing is how it plays by a spinning power roller. The surface of the cylinder (the power roller) is lined with cork and is approximately 5 inches [12.7 cm] in diameter and about 3 feet [91 ...

•More on overheating PowerRoll device, etc. Greetings, The problem with overheating PowerRoll systems is not just due to the fact that the magnets are crammed in a small space. The problem is that the all of the magnets are operated at a single voltage for the entire time they are active. With piano...

•I believe that the device or fixture on his band organ which Doug Hershberger was asking about yesterday is to hold the Allen wrench used to adjust the take up spool. It is also found in the pianos. Don Teach

•The most suitable device for amplifying musical boxes is cheap, easy to make and requires no power. It is simply a resonant board. This can be made from a thin sheet of wood, about 24" x 18", mounted on a wooden frame for strength, say, around 2" deep. Very small musical boxes can make do with a sm...

•Regarding protective devices for electric motors: nothing will protect against the starting winding being energized for any longer than it takes the motor to come up to speed. A start winding is wound with small-gauge wire in order to get enough turns into the given space, and cannot carry current ...

•There is a Bluetooth device that runs on an Android device. It is the Mega Midi or Mini Midi sequencer from Brotech Electronics: http://www.brotechelectronics.com/ The system is an application that works on Android systems and a "receiver" that you put in your instrument. I have this system and it ...

•There is a device on the back of almost all Coinola stacks that is a pneumatic the controls a knife valve in the box it is attached to. A single small nipple supplies the vacuum to close this pneumatic. In some pianos this pneumatic closes and also opens a pallet valve. I was under the impression t...

•There are metal devices available from piano supply houses which have "ears" to prevent the flange pins from working loose, but the fact that the pin keeps working its way out, means that the bushing is worn, or loose, or the pin is too small. The best way would be to put in a slightly larger pin. ...

•Rolls are mechanical devices to deliver a control signal to the player mechanism. That signal needs to be delivered at the right speed. This is the speed that matters, not the speed of the paper. Some companies used perforators with a variety of punch sizes. A critical aspect of rolls is the size o...

I have seen the above mentioned device at our local discount store. It is priced at $59.95. The music is a folded paper sheet. The sound is not great but as a novelty item it is interesting. These devices can usually be found in the Christmas section with the moving figures, etc. While not a collect...

•Solid state relays are very reliable devices for both AC and DC applications. The reference made to "crossing zero 120 times a second" has to do with a type of AC (not DC!!) relay known as "zero crossover". The purpose of this type of relay is to minimize transients by connecting the load when the ...

•Sub-title: Automatic Roll-Destruction Devices I'm always amazed at the tricks certain people will play in order to separate other people from their money. I suspect that a case in point is the invention of the infamous "automatic tracker mechanism" on player pianos made mostly after 1910. Personall...

•My tilter came with a clamping device to hold the piano to the tilter while setting up. Rarely use it though. Once the wheels touch the floor, I brace the piano from the side of the case and right it using the handles on the piano. Jon Page Harwich Port, Cape Cod, Mass. (jpage@capecod.net) ...

•Whenever you use the kind of device I presume you're speaking of, I try to get a 135 VAC model to run on 120 VAC. Otherwise, putting a light bulb socket in series with it and inserting an ordinary light bulb will drop the voltage. Try several different wattages of bulbs is necessary to get the desi...

•Correction: I called the automatic tracking device I need for my upright Gulbransen a "fishing pole" and have been kindly corrected. What I need is information on how to obtain a "Jigger" and it's linkage. A picture is on page 125 item #136 of Player Piano Servicing and Rebuilding by Arthur Reblitz...

•This is similar to a device called the "E-Bow" which was developed in the 1970's. It was a battery powered hand-held electromagnet that was used to magnetically excite the strings of an electric guitar. It produced a sustained "bowed" tone from the strings. The device is still in production and has...

•When you make your roll repair device make sure to not have a flat table area except for when you are punching new holes. For tape repairs you should have a large curve with the roll spread over it. Something like unrolling the roll over an oatmeal box. The curve will keep the tape from puckering w...
