Jean,
Interesting developements! You have taken a route that I been thinking about too. However I have recently decided to go into an other direction, namely to drop the Lenco topplate altogether. I intent to have a new topplate lasercut from 5mm thick steel that is totally flat and will be glued to a ply/mdf sandwich. I hope this way you solve all the damping issues in one go. I am still working on this and don't know the cost involved yet, but I do know that most of the cost involved will be the programming of the lasercutter, so if more people would be iterested in this maybe I can order a small series instead of just one and prices will drop dramatically. More on this will follow!
Peter
