Does anyone know of a torsion
tube spring rig that might be like a
clock spring wound about
3.4 revolutions with
a lever attached ?

The spring must be free and
not touching itself after wound.
maybe 3.9 to 4 turns.
Have maybe 4.5 to 5 lbs of force
when wound.

If you were to look at it as being a lever,
one side is 1/40 and the other is
39/40 with 40 inches in overall teeter totter length.
A fulcrum in the middle bearing 4.5 pounds of weight avd.
with extension or compression Spring on short end and mass
on long end.

you can substitute millimeters for inches since
its the ratio and not the length which
is most important.

Does anyone get my drift ?

I know its kinda like the original thing Richter built
but does not use wires.

Have you ever seen those fancy golden rich man clocks
in a glass globe
with the oscillating mass turning this way and back again
in the horizontal plane ?

but with a 5 second period and not a one second period.
[or was it a 28 day period :-)  (just being funny)]
