>>Hi,
>>I'm tuning on a PRN basis for TAMIU here in Laredo.  They finally
>>decided their black cages full of warbling songbirds and howling
>>seals needed a little discipline.  (The grands are better, 50 to 80
>>cents sharp on the top octave though, every piano.)
>
>>They have a bunch of Boston uprights (UP-125 II)  that are proving
>>quite annoying.  There is very little discernable friction between
>>the tuning pin and the speaking portion of the wire.  I got
>>suspicious, went to the restroom and got some white paper.  Swiped
>>the wires, yellow stuff, swiped the underside of the pressure bar,
>>more yellow stuff.  Not very thick, but collecting dust anyway.  When
>>I massaged the wires with the beat suppressor after the first pitch
>>correction pass I noticed that the wires were collecting a little
>>dust too, sticky. ... These are fairly new pianos, couple years at most.
>
>>When I say low-friction, I mean I can put my little hammer vertical
>>on a pin and walk a unison above and below tune without stressing my pinky.
>
>>Is this normal?  Making unisons stable is a bit of a chore.  No
>>wonder they were warbling & howling.  Do they come from the factory
>>this way? or did one of the past piana toonas oil everything up?
>
>>Over lubricated in Laredo,
