More on sounds from a saw (referring to yesterday's note).
----------------------------------------------------------
Keep in mind that the saw must be clamped FIRMLY OVER ITS ENTIRE WIDTH.
Even then the sound is rather weak and dies rapidly. Capturing it with
a microphone (connected to a speaker through an amplifier) may be desirable
for a large classroom. A steel blade of uniform width is better than a blade
whose width increases from tip to handle, as in a carpenter's saw. Hit the
blade quickly, but not too strongly, at the free end.
