Hi Folks,  I will leave my Band Saw Blade sensor set up until I record a =
few earthquakes, just to see how they look.  Meanwhile the sensor is in =
the garage and is picking up a lot of noise, both from the road =
construction, near by, and me moving around the garage.   However it all =
quiets down at night.

After this test, I do wish to pursue the idea of using music wire, piano =
wire, or the like.   I also will secure both the top and bottom of the =
wire, and put the barbell in the center.

Before I make the next device, could someone answer these questions.

1.  I know the shorter the wire the shorter the period, but If I use two =
wires, say 36", one on top of the horz and one on the bottom of the =
horz, would the period be the same as using one,
72" wire, on the top only?   Or would it just reflect the length of the =
top wire only, and not the bottom wire?

2.  Using the same mass and length of wire, would thinner wire result in =
a longer period?

3.  This was a surprise:  As I mentioned, the isolation continued for =
5hrs.   I have tried different pendulums, with different hinges.  I have =
tried different springs.  These would only cycle for a few seconds and =
up to maybe 30 mins.   Can someone explain the different, of the longer =
periond of the torsion spring?  =20

This is all new to me, but I can see why the Anniversary clock can run =
for so many days without winding.  I have experimented with clock =
escapements, and have made some wooden clocks.  I just find it =
interesting, but never saw anything that continued to move, on its own, =
like this torsion spring.
