<DIV style="FONT: 10pt arial"><B>Subject:</B> [pianotech] Tight plastic
flanges</DIV>
<DIV><BR></DIV><FONT face=Arial>Centres have become tight on the little
Neindorf piano i tuned for a customer today. <BR><BR>It's a late 60s or
early 70s piano with a "Pianic" action, and when I took out a hammer and the
wippen/jack assembly for one note to check which centres were tight, happily
the date was printed on that particular hammer, June 1969. Jack centres
are fine, but hammer flanges and wippen flanges tight.<BR><BR>Since the
flanges are plastic, what would be the more likely cause - swelling of the
plastic flanges with age, or swelling of the centre pins? Would it be fair to
assume that it's more likely to be the plastic flanges, since the jack centres
were OK, and they are pinned the other way, with the bushed hole in the wood,
not the plastic?<BR><BR>Use of Protek CLP helped, making the action much less
sluggish, and, basically, acceptable to play. But it hasn't of itself
gotten the centres as free as they should be.<BR><BR>Best
regards,<BR><BR>David.<BR></BLOCKQUOTE></FONT></BODY></HTML>
