Our chapter had a Seiler rep give a presentation. If I remember correctly, Seiler pianos are constructed without the outer rim initially. The outer rim is basically a case part, and it is put on near last. In other words, the outer rim does not really play a role in the sound creation. I think I also remember hearing and seeing that the inner rim is very thick while the outer rim is thin. Charles Neuman PTG Assoc, Long Island
