Hi List, Here's an old question from a new CAUT:  When does one finally call it quits on a set of wippens?  I'm working on an old Steinway M circa early thirties with the tilted capstans.  I would doubt that the wippens are original, but they are definately OLD, squeeky and has substantial amounts of what Steve Brady calls "gradeau" (gunk) on the rep springs at the rep-lever contact/rubbing points.  They also are "dented" in on the rep lever/knuckle contact point. Although it is only in a practice room, we don't have ooodles o dough to replace the piano.  We can afford new wippens, or I can "doctor" them one more time by cleaning and lubing all those parts which would be a lot of invested time...Not much I can do about the dented rep/knuckle spot though.... What do y'all think? Thanks Paul T. Williams Univ. of Nebraska
