Hi David,

Thanks for your answer/experience. Indeed I' have been a tad annoyed to
discover an anti friction product designed for pinning that was aggravating
the symptoms on some occasion.

Then I am expecting to find some correlation, with oxide pins that is fairly
understandable, with graphite bushings may be too, but I've seen problems on
Yamahas too.

Then of course the final answer is to keep that product for less sensible
parts (damper wire) or not expect more than it gives.

My solution was to develop speed and efficiency for pinning. I concur with
Roger and all old school boys (sorry Roger !) .
When often notice with time that what have been told us from the start was
not without reasons !

BTW, I have a recently rebushed keyboard that have lost a lot of side play
under very dry conditions (and tighter balance hole also). I guess that
during winter one should not ease the keys too much, the hole will be larger
in humid season.

Best of Christmas.

Isaac

  Isaac,



  I use Protek and find it often does the job but occasionally it will do
nothing.  I can't say as I've found it to seize up centers.  I'm using Joe
Goss' Goose Juice also these days and it seems to work well.  What the
difference between it and Protek is, I don't know.



  David I.

  In my experience Protek CLP make some bushings very sluggish or even
blocking after some time.



  Have no correlation between the kind of bushings (Renner most probably )
that produce these results on a regular basis.



  The lists being mostly driven by US techs and Protek being an Us product
widely used, nobody seem to answer to these questions most probably because
of the political correct attitude on the lists (is not it guys ?)



  So let me say that is how I understand your silence on that matter
(strange as you’re generally willing to talk on any product/process used)







  Happy Christmas to all.

  The Steinway "Permafree II" action centers are impregnated with a teflon
  solution, which lubricates and provides additional firmness. We had quite
a
  bit of discussion of this over the past couple months, with respect to
  firmness versus friction.
      No other manufacturer uses this method. Most others are pure,
  "unadulterated" felt, some have graphite applied to one surface. All
others
  will respond to lubrication with Protek, and/or to shrinking/sizing with
  alcohol/water. Steinway will not respond to either, due to that
  impregnation with teflon. Pure methanol, a controlled substance, is
  available (at least in colder climes) as gas line "de-freezer." Eric
  Schandall says he thinks ethanol will work as well.

  Fred Sturm

  When I was at Steinway last summer, I could have sworn Eric told us to use
Protek on the bushings. I will see if I can find methanol here in "warm and
sunny" Alabama.
