Repairing the Accordion
Bellows in a Duo-Art

While this video is pretty much self-explanatory, I should add a few comments. One, the accordion pneumatics in the piano for which this video was created are covered with tan pneumatic leather that was not sealed when the piano was restored. Twenty-five years ago, it wasn't considered 'common practice' to seal the leather. In fact, in 1975 a more common practice was to use thin pneumatic cloth instead of tan pneumatic leather, and the subject of the "best" material for the accordions continues to be debated. However, as can be seen in this video, thin pneumatic cloth might not have been the wisest choice -although it had its advantages. Secondly, Dow Corning 3140 didn't exist when the player piano, for which this video was created, was restored. Had a sealer been used on the leather, the most logical choices would have been egg white or diluted Carter's Rubber Cement.

Regardless of what 'was' done or what 'might' have been done in the past, the truth is that the leather on the accordion pneumatics is still quite supple. So, the aim of the procedure is simply to seal the leather -nothing more, nothing less. Were I to consider what I would do today, my choice would be clear. I would seal the leather with Dow Corning 3140 after completing the recovering process.

Since "Player-Care" is an internet business, I prefer that we correspond via E-Mail (click here to fill out the 'Request Form'). However, if I'm not in the middle of some other activity, you can reach me at 732-840-8787. But please understand that during the hours from 8AM-5PM EST (Mon-Sat), I'm generally quite busy. So, I probably won't answer the phone. If you get the answering machine, please leave a detailed message stating the reason for your call. Also, repeat your name and phone number clearly and distinctly. By necessity, I prioritize everything in my life. And, if you call and just leave your name and number, and ask me to call you back, it might be a day or two before I return your call. Why? Because I don't know why you want me to call and I might not be prepared to assist you in an effective and efficient manner. If you leave me an E-Mail address (which I prefer), spell it out phonetically. The more you do to help me, the more I can help you in return. Don't rush. You have four minutes to record your message.
