•Of course Julian Dyer [in 200907 MMDigest] is right that recovering the punch matrix is an important step in creating a high-quality emulation of a music roll, contrary to Stanford's stated position. However, I take issue with Julian's assertion that punch matrix reconstruction is complex and time ...

•Punches are available from pipe organ supply houses such as Organ Supply Industries, Klann, Colby, Kimber-Allen. (URLs available at my web site.) For very large punches used for making pouches, etc., we use steel or cast iron water pipe that has been ground down to size and sharpened. This requires...

•Hello -- I'm new to this list, although I've read at least 100 articles in it. I found it via Altavista by searching topics like "band organ", "punching paper rolls", etc. My question is: I'd like to start arranging and then punching a few rolls, even though I don't have an organ. I'll have to rent...

•In response to Harald Mueller's request for information about punching music for 20 note organs... Peter Willis of England, at http://websites.ntl.com/~p.willis/ has a web site offering information about a mechanical punching machine. He publishes an introductory book on how to mechanically punch m...

•Harald, About two years ago I built a computer controlled punch in order to produce punched rolls for Raffin 20- and 31-note organs. It also produces a 26-note version of the Raffin scale, and any other scale you like, even 88-note piano music! The computer software is designed to read standard MID...

•Mechanical music, printers and voting machines Hello MMD readers, With the focus at this time on the State of Florida, and on the subject of voting machines, I couldn't help but draw a parallel between the variables in the Presidential election tallies and what faces one in the sphere of mechanical...

•Francoise Dussour asked about punch card patents. I have a good friend who works at the UK Patent Office, whose job is to answer public enquiries. He is always willing to help people with genuine patent questions, but might be irritated by requests such as "numbers of all player piano patents" whic...

•I made a punch very similar to that which Pat DeWitt describes. I have most tubular punches, from very small to about 1-1/2" in 1/64" increments in the small sizes, and in 1/16" increments in the larger sizes, but I never got the size needed for Ampico pouches so I turned one from some decent steel...

•At the risk of sounding like a salesman for Pace Punches, I have to recommend their tubular punches for adding holes to paper rolls. For a while I was making little hand held holders for these punches to punch standard piano roll sized holes. If you don't have a lathe, you could probably make holde...

•To go for the gusto -- get a ring punch set from Weiblen Spezialwerkzeuge (Weiblen special tools for organbuilders) in Germany. I did! They are great for player work. The only hitch-in-the-git-along is they are metric (mm) sizes, not in inches. http://www.weiblen.de/en/special-tools/working-with-le...

•Hi All, I once saw a music roll hole punch made by adding a tubular punch to the body of an automatic center punch. This is a device that has an internal spring that cocks as you push down on the barrel and then releases the spring with a snap to drive the punch. That way, it is not necessary to hi...

•Robert Streicher, an excellent machinist in Pond Eddy, New York (who actually lives across the Delaware River in Pennsylvania, but with a New York mailing address; see the MMD archives for all this) used to make the punch Pat DeWitt describes in the 090514 MMD. But I believe he stopped making them...

•A Yankee screwdriver, the kind with spiral plunger which turns when pushed in, was my solution. I machined a screwdriver tip into a punch with the center hole exiting out a side pocket. With the rotary action, the punch cuts a delicate hole without dimpling. I found it was easy to edit on the piano...

•Hi, It seems that most of the respondents on this subject suggest hitting the punches onto hard wood end grain. I too, would go along with this but once you start using punches larger than 1 inch diameter you have to use more and more force with the Hyde Mallet. Striking the punch hard and possibly...

•I bought a Lee Valley model 1125 punch set, catalog no. 33Y01.05 from www.leevalley.com and it works just fine. It twists as you push down and gives a clean hole. The punches are 1.5 mm to 4 mm. I think I read about this on the MMDigest a couple of years ago. Hal Klassen

•Hi All, I'm looking for someone to punch valve facings for me. I already had the leather split to my specifications. The sizes I want punched are 3/4" OD and 5/8" OD with a center hole that's 0.075". If you are interested in the job, please contact me. Musically, John A Tuttle Player-Care Brick, Ne...

•Terry Bender asked [in 240304 MMD] about someone in the US who can punch 20-note rolls from MIDI files. Brian Thornton at Pipes of Pan Music in Tennessee is set up to punch many sizes of music rolls for organettes and organs. His punches are MIDI controlled. All of the rolls I have ordered from him...

I, too have been VERY put out by purchasing punches that would not cut hot butter. Perhaps I am just too fussy...

•Hallo MMD friends! I ask you if you have an idea on this interesting question: Who has invented the punched card ? Is it typically French, or did other countries find this genial invention? I have some dates: 1802 Patent by Jacquard (1752-1834), punched cards for web-machines 1842 CH. F. Seytre, of...

We were invited to contribute material for a museum display in that town. Lynn...
