•Don Teach mentioned today the neat music roll punch made by Robert Streicher of Pond Eddy. He still sells them and I've made thousands and thousands of punches with mine, honing it now and then on a piece of emery or crocus cloth, and it's still going strong. The punch is simple to use: just positi...

•Joel Hoshaw made mention of a mis-punched roll of "Humoresque". I am curious as to when he acquired it. I too have a roll of this, C-103A, acquired from QRS about a year ago. To my memory, my roll is correctly punched in that I detect no notes missing or added -- at least as well as my memory of ho...

•Concerning the problem of stenciling: It was mentioned recently that one could use the standard commercial punches that tool and die makers use. Before Andy Taylor goes out and purchases a set, he should read the following: I went to my tool cabinet and found a set of commercial tool shop punches u...

•I seem to remember several discussions in MMD about the various step intervals that Duo-Art, Welte & Ampico used when perforating their rolls. I've gone through some of the subject matter headings in the cross-referenced library but evidently must be looking in the wrong spots. Can anyone point me ...

•I have recently built the MIDster PUNCH machine designed by Bob Essex. I had built a John Smith Busker organ and am punching my own music, but I really wanted to find a way to punch music automatically. 12 plus hours of hand punching is fun, but it does take time so that's when I turned to the MIDs...

•The recent thread about printing templates from MIDI files in order to punch books and rolls prompts me to ask the question: Why templates? Why not punch directly from the MIDI file itself? It surely must beat clicking away with a hand punch for hours on end. My MIDster Punch system has been used s...

•It is fair to say that John Conrad Kleinbauer's comments with regard to the early version of MIDster Punch are partly, but perhaps not entirely, correct; but nevertheless I appreciate his comments. Mistakes in the early documentation, rather than the circuit and the software, are to blame (for whic...

•I am glad to see the MIDster Punch being discussed on MMD. I am one of the many around the world who is happily punching away. I found the "plans" to be very easy to follow. My only problem was I was not a computer person. This project brought me into the world of computers and music. Bob Essex was...

•Hi All, Bob Essex is correct, you can increase the power supply voltage of a stepping motor to get more speed. Let's say you are using five-volt one-ampere per phase motors. Increasing the supply voltage to ten volts will double the speed. In practice I use a twelve volt power supply on my five-vol...

Hard to believe; it's such a big country ("The Land o...

•There has been some discussion lately on the subject of punching your own rolls or books for organs. This is something I am planning to do in the near future, however I am not sure how to do the actual punching of the holes. I have used the "Midiboek" program to create templates for the book music...

•I have been following the thread started by John W. Miller in MMD 010723 and have waited patiently for some mention of the MIDster Punch system which punches Raffin 20 and 31 note music direct from MIDI files. I felt sure that among the great many punch builders who have bought the system there mus...

•It has been related to me by Ken Smith of Columbus, Ohio, that there was one hobbyist who used a drill press for a punching machine with a home made punch and die set. The punch and die jig should not be too difficult to make or a commercially-available set could be purchased. Here's how I would ap...

•I have obtained a manual punch machine for punching cardboard books. It has a replaceable punch and die for different size holes but it didn't come with any different sizes (just the one that was in the machine). I do not have any metal working machinery so can't attempt to make one. I need to have...

•For Sale: Book Organ Punch -- If anyone is interested I have a punch for book music for sale. Galen Bird

•Hi All, I need to know the size of the punch used for cutting the holes in a 65-note music roll. I'd also like to know where I might purchase such a punch. Background: An artist in New York City is creating a piece of art which centers around a continuous music roll that will be used to play percus...

•Bob Stewart asks in today's MMD about a hand punch for "A" rolls. Bob Streicher used to make and sell for a few dollars a spring-loaded hand punch that he would machine for almost any hole size you specify. I'm not sure these are still available. Bob had difficulty in finding a supplier for the bas...
