[pianotech] Rendering problem

[Farrell]

So you think you're so smart Tom. He didn't say it was a Baldwin!

Having said that, I tuned one of my least-favorite pianos I service regularly - a 70-some year old Baldwin L with  rusty strings and the WORST rendering problems I have encountered! I dump a bunch of Protec CLP on all the forward contact points and especially the understring felt - it doesn't make the problem go away, but it sure does make it less bad.

One thing that makes the rendering problems even worse on this piano is that many of the tuning pins are almost loose.....  :-(

Oh, wait - is Tom suggesting more Baldwins than the one I service suffer from this affliction?   ;-)

  WD bad idea. Protek will be the suggestion most made.  This can also be a design problem and not correctable with lubrication. I use more than a drop but am sure to keep the juice away from the bass string windings. 
  Someone on list mentioned treating problem bass strings with protek so maybe I'm being too cautious without reason in this regard.

  P.S. how old is this Baldwin ?

          Is there something that can be applied to rusty bearing points to facilitate rendering?(Other than restringing) It's really frustrating to turn the pin...turn the pin..pounding HARD on the key..turn the pin ..still no change in pitch...turn.. and then 5 cents (or 10) change at once.Then we go the other way...
          I have a customer with a grand player piano that has this problem through out much of the treble.
          I've been told to apply WD-40 to the bearing point with a toothpick. I did that. It probably helped some, but not enough.   John
