Hmmmmmm, Guy, might our relatively higher humidity affect the effectiveness
of the Garfield's?  Houston has "humidity", but it isn't radical.  But it
sure is way above 17%.

  Les, Jim, list,
     My dad started me on Garfields 30 years ago. In my dry climate, it
actually works better than CA glue. A 50-50 mix with methanol or denatured
alcohol, applied with two or three passes, using a complete 4oz hypo bottle
per block has been quite successful. The instrument needs to remain
horizontal for at least 24 hours, and wait two weeks before tuning. Many of
the pianos I doped over twenty years ago are still pretty snug. In most
cases, only one or two pins may need to be sized-up. That's 99%.  A thinner
solution can be used when there's not good penetration, and a super-thin
solution can even-out the feel of jumpy blocks. I have never had a block
destroyed by the solution, although we due loose track of customers, or they
trade-up, or whatever. At the plant we've got about a cord of old blocks.
I've seen many that had been doped, and if they are de-laminating, I'm sure
they would have done it without the solution anyway. Penetration does seem
to stay near the top, but hey..... that's where the pin is loose, no?
     I believe that history and climate are very major factors, and that
techs from different areas will have varied success. If I were to advise the
world on the use of CA glue, based totally on how it works at 17% RH, I'd
say don't bother. But.... I know how to deal with it, so I'd say knock
yourself out. One way or the other! <G>

    Les, List,

    I don t know if this was mentioned but past Journal articles have shown
pictures of pinblocks that were doped with different solutions (not CA glue)
and it shows how the solutions generally don t penetrate through the
pinblock and have a tendency to destroy the upper one or two laminates.
Sometimes within a couple years.

    The correct way (according to the article) to use Garfield type products
is to remove about every 15th pin and fill the holes several times until it
is saturated . Before CA glue I did this and it does work. Of course, it
takes time, you risk breaking strings, etc. etc. but IMO the superficial
doping of a pinblock is not good at all. In cases where it did work probably
you could have spat on it and it would have done about the same. (Just
joking. No comments on the dangers of saliva, please.)

    CA glue, as stated in several posts, is far better, and doesn t seem to
destroy the block over time.

    I went over 50 miles to this house to discover this untuneable piano had
about 5 really loose pins, and the rest were just fine!  I neither took my
hearing aids nor my Computer for TuneLab, so ended up pretty much struggling
with the tuning, but did no pinblock work whatsoever.  But thanks for
opinons. I'll certainly keep them for future use, which WILL come about one
of these days.

    thanks
