•I am restoring a late Steinway Grand Duo-Art. Unfortunately moths got to much of the felt and I have to replace a good part of it. On the top deck of the pneumatic stack, as many of you know, there are long strips of felt on either side of the valves, to presumably act as dust shields between the t...

And even with a veneer >> look? >> >> If it were possible, it had to be reinforced cement or concrete.

•Hi All, Even though I've worked on literally thousands of player pianos and read every service manual I could get my hands on, I have never yet come up with or read an accurately descriptive explanation of how to adjust the forward roll or rewind friction brakes. The question is: How Tight Is Just ...

•-- non-subscriber, please reply to sender and MMD -- Another possibility...! It was very interesting to see all respondents to the original question assuming that the effect of under floor or in-floor heating would immediately lead to dryness. This is not always the case though. A friend of mine ha...

•I would like to add just a bit to this discussion since I have performed the replacement of a Steinway XR system. Most of what has been said is correct. What has been said about the scarcity of finding the correct replacement parts is a bit misleading. Given enough time and patience, the exact repl...

•Some of you knew Bob Streicher better than I, but many likely not as well. So here's my two bits. Harvey Roehl put me in touch with Bob in the mid-1970's, describing him affectionately as a "woodchuck" due to his hermit-like existence in the wilds along the Delaware River, while praising his astoni...

•The world of clock repair faces a grave crisis (that is, besides the obvious one, which is that clock practitioners all have one foot in the grave already !) Chiming clocks typically beat their hammers on 'chime rods'. These are steel rods, about 3.5 mm in diameter, that are supported at one end in...

•Over the MMD years there has been a large number of articles about motors in player pianos. Once upon a time in some publication I cannot find there was an article on servicing electric motors in reproducing grands. The article mentioned thrust bearings in the motor. I read the article and never th...

•I attended the auction of mechanical music items in Sydney (mentioned by Michael Wolfe) and can add some more details. All prices are in Australian Dollars. On top of the prices shown, the auctioneers applied a 10% "processing fee' and a "bank charges recovery fee" of 0.08%, i.e. a knock-down price...

•Install Disklavier Mechanism in Non-Yamaha Pianos! It is no longer necessary to be stuck with a Yamaha brand piano if you wish to own a Disklavier. We can transplant the solenoids from a Disklavier stack into a new, heavily built, high-quality stack rail designed by me, which is covered by my paten...

•Larry Broadmoore gave a great description of his modification of the Disklavier parts to operate an expression piano. Seems like this should be a popular idea for an inoperable piano -- I'm sure there will be some discussion about converting a complete machine. Anyway, I have a question about his p...

•Hi All, For those who are interested, I just posted a new web page about sealing Kimball plastic block valves to the tiers. It's at http://www.player-care.com/kimball-block-valves.html The technique also works quite well when doing individual block replacement on-the-job. And since the hot-glue con...

•Does anyone have information on how a set of bells are mounted and tubed in a Wurlitzer 146-A (late model)? Bob Stewart

•The Wurlitzer 146-A did not properly have bells, although the 146-B did. So the question probably should be, How are they mounted and tubed in the 146-B? The interior considerations for the 146-A and 146-B should be the same, the principal difference between the models being the side wings and the ...

•In response to Robert Stewart and his request for bell installation information on his Wurlitzer 146-A. Robert, I have an early 146-A that had a set of replica bells nicely installed long, long ago. I will take some photos this weekend and send them to you and the MMD. It would be great if someone ...

•I'm still looking for someone who can send me pictures of the bell mounting and tubing of a Wurlitzer 146B. Please contact me if you can help. Bob Stewart

•Recently I received a snare drum beater from Player Piano Parts Inc. (successor of Player Piano Company) and I just wanted to say that it is a great value. I am still working on my organ project and now have a name -- it will be my "Organelle." But that is a different story. I just wanted to mentio...
