Hi, Richard The pictures that mr. Steingraeber showed at the convention were of a soundboard already installed in the piano, with the rim and everything. He told us that he used a "plastic-hammer" to knock on the bridges. He also told us that they thinned the board by sanding it. But it was the last lecture at the last day of the convention, so you may be excused.... :) Kjell Sverre Fardal NPTF / Norway -----Opprinnelig melding----- Fra: pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org] På vegne av Richard Brekne Sendt: 20. oktober 2003 20:03 Til: Pianotech Emne: Re: Soundboards: Thickness and Area I'll have to check on the specifics. Tho I believe the assembly was in the piano for the proceedure. Just where and how they thin to get the desired results, he didnt have time to go into, tho I will see if I can find this out. Kevin Gouldman is an American builder in Danmark and knows Uddo Steingræber fairly well, and I believe he knows very much about how the Steingræber factory does this... so I'll ask him as soon as I can get to it.
