Hi all,
Im just getting back to this now. Im looking at building something 
based on Chris Chapman's piezo design from 
http://jclahr.com/science/psn/chapman/piezo/index.html
Im having trouble with the sketch however. The circuit is no problem 
just the actual construction of the piezo sensor. WOuld anyone by any 
chance have a clearer or more detailed drawing i could follow. I hope i 
am not causing any offense to the original artist. It is simply my lack 
of knowledge with these things that prevents me from understanding the 
original sketch.
Thanks again
Nicholas
