[G] > Regards, > Joe Garrett, RPT, (Oregon) Well, The panel itself is very thin. Perhaps as thin as 4 mm ? I will measure it today. I remember seeing a few overdamper pianos built with like 2-3 times as many ribs as we normally use today. These were sort of triangle shaped rims...ie good stiffness with minimum mass. The panels on these were also thiner. Not the greatest sound, but that probably had more to do with scale issues. This one is probabably pretty free to move. It has quite an active natural resonance at any rate. Tho with really low tensions on the strings (compared to todays) and dinky little hammers... It wasnt meant to create the 130 db level for sure :) I have lots of time on my hands for this project... deadline round October. So I will you posted as it developes. -- Richard Brekne RPT, N.P.T.F.
