Hi all,

Have explored further into the test curtain rod bracket with the flat 4
springs; and I see its further capable of attaining
a reasonably stable natural period in the 2.2 to 2.6s range...which I think
is pretty good for such a small size unit.
The maximum period I saw was 3.4s; but it was grossly unstable there.

I've no past home brew vertical experience at all; but, flat springs too me
initially, look to be the better way to go
for a short period vertical with a very light weight mass.  The variable
period "tuning" and "stability" aspect is
something one probably wouldn't have much control on, with a comparable
traditional straight spiral main spring.

Anyway.....onward in time eventually to other suggested pivots....and
whatever problems occur with such.

By The Way:

I note Google is supposedly launching their first web browser tomorrow for
download called "Google Chrome".
That will also be interesting to explore and compare to all the other
browsers.

Take care, Meredith
