Richard and one of his students, composer Doug Quin, taught me 
everything I know about the piezo disk.

I've used these transducers on everything from clipboards to huge 
sheets of sheet metal to train tracks. I usually use a screw gun 
(and sheet metal screws) to screw the disk onto the vibration 
source. This makes a very tight junction between the two. Vise 
grips have worked well for those places where I can't use screws. 
When screwing them on, or vising them on, take care not to short 
out the piezo ceramic center and the metal armature.

Maryann Amacher is also a hugely brilliant composer using 
custom transducers. Anyone here know about her gear?
