If that is = not an option you might try putting a motor speed control on like that used for = router speed controls. On one occasion I put the suction box in a nearby closet = and ran hose to the piano. This wasn't for noise control but for space problems = but it reduced the noise problem to zero. I had one customer who = considered putting the suction box in the basement and drilling a hole in the floor = behind the piano for the hose. You might try putting some oil on the motor = bearings.</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>John Dewey</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px = solid; MARGIN-RIGHT: 0px"> <DIV><FONT face=Arial size=2><B>-----Original = Message-----</B><BR><B>From: </B>John Tonyan <<A = href="mailto:tonyanj@hotmail.com">tonyanj@hotmail.com</A>><BR><B>To:= </B><A href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> <<A = href="mailto:pianotech@ptg.org">pianotech@ptg.org</A>><BR><B>Date: </B>Wednesday, October 17, 2001 2:47 AM<BR><B>Subject: </B>player = piano vacuum motor noise<BR><BR></DIV></FONT> <DIV><FONT face=Arial size=2>The noise from my client's vacuum = motor in her Scaffer and Sons player piano has increased through the years.
