On some of these pianos the arc of the but is intersecting the arc of the jack to help this - after checking the usuall causes I've had success simply inserting a #22 music wire between the wippen flanges and the action rail. Simply loosen the flanges insert the wire and tighten the flanges - this changed the jack position just enough to allow the jack to return - though at times I've had to shimm up the hammer rail as well ( as you sugest John) Hope this will help you >From: staytuned@idirect.com (John Lillico, RPT) >Reply-To: pianotech@ptg.org >To: pianotech@ptg.org >Subject: Re: Heintzman console jack return problem. >Date: Mon, 6 Nov 2000 10:57:12 -0400 > >Doug, > >Can you give us the serial number, style name or action maker?
