Quite a few vintage pianos originally had two cloth punchings on the front rail pins. The French liked to do this, and it seems to have been the standard for Blüthner for a long period of time. Just recently a client contacted me, looking for the thin (blue) felt punchings that were used in conjunction with the cloth punchings for his Blüthner patent action grand. He maintained there was quite a difference between one thicker punching and two thinner ones, and that for the intimate tone of his piano nothing else would suffice. Perhaps this has to do with the unique regulation and feel (no aftertouch) of these pianos. However, I am getting increasing requests for the same thing for the back rail. Many pianos had a thin felt strip (1.5 - 2 mm) underneath the back rail cloth. It appears that 2 mm of felt under 5 mm of cloth is more quiet than one 7 mm strip of cloth. Can anyone corroborate this? <?smaller>Jurgen Goering <?/smaller> </div> </body> </html>
