>as new tools that are capable of cutting the plastic would have to be made (and made to the same high tolerances as the wood cutting tools).

Not only that, as any woodworker or machinist will tell you, tools used for different types of wood or different types of plastic are themselves constructed differently, even hand-held reamers (fluting, edge angles, etc.). I'm sure Clark Fobes and other can relate their stories of trying to find the right power & hand bits for repeatable high-accuracy cutting.

This evening, after I get back home, I'm going to excerpt a bit from the Benade book "Fundamentals of Musical Acoustics" and explain some of the ways why materials can and do affect the sound :^) So far I've talked about wall vibration - which has a very small amplitude. There are other properties which, given the right case, can affect the sound. I don't have the book handy right now, since I'm supposed to be working :^)

For those that don't own this marvelous book, I highly recommend it. The math is at a high school level and doesn't go much past a radical sign. There are thought and actual experiments at the end of every chapter.

As reference books go, it's dense - for those that study computer languages, it's on the line of the K & R 'C' book, only bigger. Each page is packed full of material to mull over. If you'd like a copy, I'd recommend contacting Amazon.com through either www.sneezy.org (I get a very small percentage of the price of 13.56) or through Gary Van Cott's site (www.vcisinc.com) so he can get the very small percentage :^)
