•Sam Harris wrote, "I have read the Chester Kuharski article ..." I have only a small contribution to add here: I know very little about reproducing pianos, but unlike much of the general public, I do know the difference between a player piano and a reproducer. The reason I know this much is that I ...

•Does anyone have a copy of the Duo-Art paper Chester Kuharski wrote? Someone sent me a copy a few years ago and it looks like a photocopy from a "comb" bound collection of articles. The article started on page 92 and was entitled "Kuharski on Duo-Art." I have through page 101 but I'm missing page 9...

•>> Does anyone have a copy of the Duo-Art paper Chester Kuharski wrote? Good old Chet. I worked with him at [radio station] WTSO, Madison, Wisconsin, where he taught me how to replace the giant tubes in the radio transmitter and lectured me on the difference between a reproducing piano and a player...

•Hi Sam and Group, "Kuharski on Duo-Art" is a part of "Technicalities from the AMICA News Bulletins 1969 - 1971." If someone has not already sent it to you send your snail mail address and I will send a copy to you. Jack M. Conway, Los Angeles, California, USA

•A MMD Member was kind enough to scan and send me the text of page 96 which was from AMICA "Technicalities" 1969 to 1971. Thanks a bunch and once again MMD has yet to fail to produce _super fast_ results. You all are great!! Sam Harris Greenville, North Carolina www.PlayerPianoShop.com

•Did Chester Kuharski ever write a book or articles about reproducing pianos? I may have asked about him before, for it was from him that I learned what a reproducing piano was. He said I'd get a big finder's fee if I could locate a Duo-Art for him. Chet was a solid, sturdy Polish guy, probably from...

•I was glad to see Phil Dayson's objective measurements of bump in the curve for air flow vs. valve gaps. Is that measurement of .035" for cross valves or round valves? I would be interested to know at what value the restriction becomes a problem for both types of valves. From what Phil and Craig Br...

•I've always liked mechanical stuff, though I haven't fooled with mechanical music beyond fixing a cuckoo clock with an incredibly annoying music box inside it. But I've found this list fascinating: I'm interested in the history of technology, and I teach technology stuff to teachers. I have a coupl...

•[ Ref. 190822 MMDigest ] So, it must have been Mr. Edgerton's Mechanical Music Center that I visited when I lived in Connecticut in the 1970s and '80s. If I'm recalling it correctly, it was a very large building with lots of open space within, and there was an absolutely monstrous mechanical -- uh...

•Sheesh! I know approximately nothing about piano rolls, but I do know a bit about schools and research. And I fully agree with Mr. Reinhart's polite suggestion that some professors have rocks in their heads, a condition due principally to arrogance. No good scientist can ever afford to ignore infor...

•I'm putting the finishing touches on an expression box from a Steinway Duo-Art. I'm a little confused about how the box should chart on the bench. Some have informed me the theme and accompaniment difference at the zero intensity step should be around 1" H2O, and the difference at the 15th intensit...

•Hello MMD readers, With great interest, I've been reading the recent string of postings about the American versus the British Duo-Art players and also the texts about the differences in the expression boxes. Having made Duo-Art rolls which "push" the entire spectrum of the instrument, for years, I'...
