My previous Sine Curve page did not have this mechanical
device generating a sine curve. The sine was just traveling
across the page. I asked viewers to contact me if they knew of
a device that would generate a TRUE SINE CURVE. J Buck
submitted a suggestion that pointed me in the right direction
to construct this mechanical device. Thank you, Mr. Buck, for
your insight and for the stimulating correspondence we had
during the refinement of this device.
