•I would like some information on paper to cut or punch 20 note keyless organ music into. As my location is in the nether regions of Australia, I would appreciate information pertaining to the south eastern quadrisphere of the world if possible. What I would like is - a description of the papers whi...

•I like the idea Spencer Chase proposes for his personal punch machine and software. The MIDster punch machine is also a great idea. Trouble is, I'll never find the time to make one of these machines. When will some entrepreneurial fellow produce a few for sale? I'd think there would be at least a f...

•I would also like to build a "universal" punching machine, mostly for organettes (of which there are many different formats). My idea was to create a "MIDster" type machine, but with interchangeable punch/die sets. It seemed to me this would create a much more versatile machine, whilst keeping the ...

•I would appreciate some education regarding the tempo punchings needed to set the tempo for the organ model. Several original Duo-Art organ rolls in my collection have a few large punchings in the start of the roll. Since they are in the beginning of the two rolls, and long before any ventil, expre...

•The Herschell Carrousel Factory Museum is about to punch some music rolls for Wurlitzer A.P.P. or Caliola. I hope to find a machine which can play these in the North Tonawanda or Western New York area. I need to play all new rolls to check them before offering any for sale. Your help will be greatl...

•The purpose of our Ampico roll recutting project is to make punch-for- punch replica copies of rare rolls from our personal collections that have never been recut before or have not been available as a punch-for- punch precision copy. This will allow collectors the chance to own rolls that they wil...

•It may be that Seth Brown's problem in getting clean punching from his Leabarjan perforator isn't because the punch pins are not sharp. I recall a trip years ago to visit the late Eddie Freyer, who was a master perforator of rolls. Eddie explained that over long use the holes in the die plate which...

•Blank paper for music rolls is available for those who punch their own music rolls. The material is white paper coated with polyethylene on one side. Thickness is .0033" (0.09 mm). Length is 1000 feet (300+ meters). Available now in width 5.51" (140 mm), for 20-note street organ, and in width 4" (1...

•A wise old friend once told me that building the paper punch (the perforator) was the easy part. Putting the holes in the right place is the trick -- and he was right! Don Teach Shreveport, Louisiana

•Bob Streicher was famous for making manually operated single-hole punches for use in editing or repairing paper music rolls. He used spring-activated center punches that he got from some company and modified them to punch a hole rather than to make a center dimple in material. The replacement tips ...

•Hello Robert, the MIDster punch software runs in DOS. You can add new MIDI files to be punched by copying them into the same directory as the punch software is stored. I don't know which version of the software you are using but in my case I have three different punch options: 20-, 26- and 31-note...

•[ Mark Williams wrote in 160506 MMDigest -- > Each punch would descend into a mating die to enable a clean cut > rather than a torn punch (very similar to a plastic comb binder > hole punch). Your comment about comb binder punches makes me wonder -- must the punched holes be round, necessarily? Pau...

•So far I have discovered that while hollow punches take quite a severe whack to punch through heavy paper stock, I believe that punching is the way to go. I punch the inside hole first, then use a small jig to center the punch for the outer circle. It would be nice to have an automated production d...

•I fear Lester Hawksby will have trouble running a punching machine where the paper is pulled through by the take-up spool rotation, rather than by feed rollers. He will be totally reliant on the paper rolling up tightly without any tendency to slip. This can happen in any player piano and if it hap...

•I've been trying to figure out a good way to punch my own piano rolls from PUNCHmidi files. I had contacted Julian Dyer a while back but unfortunately I can not afford to pay $60 for 4 copies of the same roll. I decided that I will attempt to build my own piano roll perforator. Here are a few desig...

Does anyone know a source for good quality punches for leather, pouches, etc. Thanks, Doug Adam

•[ Adapted from 960227 MMDigest ] Over 100 years ago a punched paper "music roll" was used to control a complex telescope built to photograph a total eclipse of the sun. It is described on page 360 in the book, "Stars and Telescopes", by David P. Todd, published in 1899 by Little, Brown & Co., Bosto...

•Lasers seem to be a great idea for punching rolls, but will need a lot of development. Also, they may be too cost prohibitive. Here is something that many people could use: a perforator design that could be built from commonly available parts, and ran directly off of Cakewalk. how about it? "Set la...

•I wanted to amend my statement about using felt punchings for the flexible connectors on the Gulbransen. I should have said "action felt" punchings. The difference is that action felt is woven felt, designed to take a beating for the life of the piano. It is the same felt used on the piano action s...

•We have heard many times how the automated loom using punched cards invented by Joseph Marie Jacquard revolutionized the weaving industry. It has also been noted how this design influenced the player piano and other roll- and book-playing mechanical music machines. But Jacquard himself was influenc...
