Steven, One of the reasons why these conical Wurzen FR punchings are used in our trade is because they ensure a very precise key dip, which improves the regulation (assuming one knows how to regulate well). A more precise regulation gives us a more precise 'feel', and a louder tone as well as the transfer of energy will have improved. The other reason for using these punchings is their firmness. A more sturdy/firm punching causes the key to 'land' harder i.e. less energy is absorbed (or cushioned) by the soft punching and the harder landing causes the transfer of more energy to the other side of the key, the sea saw. Some years ago there were some very interesting discussions about this topic. All the info is to be found in the archives and an article was written in the Journal. friendly greetings from André Oorebeek Antoni van Leeuwenhoekweg 15 1401 VW, Bussum the Netherlands tel : +31 35 6975840 gsm : +31 652 388008 www.concertpianoservice.nl "where Music is, no harm can be" On Apr 12, 2009, at 4:22 AM, Steven Hopp wrote: > Terry, > > Good point.
