    When I was just starting out, I bought an old Steinway 1098 on which =
to practice aural tuning. The pinblock was shot, and I had to shim =
numerous pins just so that I could practice on it. I had been given some =
of these by someone, and I used a few. They were really a struggle, both =
to install, and sometimes to tune as well. I found that in a case like =
this what worked much better was to use cloth backed sandpaper, 80 grit, =
with the grit turned toward the pinblock. I cut it so that the ends =
didn't overlap, cut it just to that it covered the threads, and inserted =
it into the block so that I could just see the ends below the top of the =
plate. I then put the pin into the hole, gave it a couple of whacks, and =
turned it the rest of the way in.  The pins that I repaired in this =
manner felt very good, were nice and tight, and didn't lose their grip =
as long as I had the piano, which was for years, and I was tuning that =
piano a couple of times a day for practice.
    Of course, I would only do this on a piano which only had a few =
loose pins, and only then if a rebuild was not what the customer wanted. =
But I have saved a couple pianos by doing this, after someone else had =
told the customer that nothing could be done.

    Are they still a recommended fix for loose tuning pins?=20
    Has anyone actually, used them and been satisfied with the results?=20
    Did I possibly use them the wrong way, and have been unjust in=20
    my condemnation of them?=20

  I have never used them, but I have seen them in lots of pianos. My =
experience=20
  is that they were used by someone who didn't know how to use them, or =
used=20
  them because they didn't' enough to recognize that they were at most a =
stop=20
  gap solution for a cracked pin block.=20

  Some of the time the "tech" pounded the new pin in, but forgot to =
shore up=20
  the pin block. As a result, not only did the pin block delimitate =
more, the=20
  sleeves were drivin intop the top rail of the action. This, of course, =
made=20
  removing the action a bit of a challenge.=20

  I would not recommend using them. If the piano has a cracked pin =
block,=20
  convince the customer it has to be replaced. If she can't afford that, =
use=20
  larger tuning pins, but warn the customer what is going on, so that =
she knows=20
  you didn't fix the problem permanently.=20
