Gary,

This is a prototype I built earlier this year (2006).
It's made from .25" acrylic and brass tube and rod.
It works and keeps fairly good time.
9.78" pendulum, 1 sec period, continuous loop with no winder.
You just move the weight back to the top which disturbs the clock position less, and is fast and easy.

The next one I built looks pretty much the same but does not have brass lantern pinions (has acrylic pinions) or adjustable pallets which saved some work. It runs about 18 hours on 1 pound.
It has run continuously since about May and is off about minute per week.
(no picture yet of the newer version will forward later)
I may try a wood version which would have to be larger.

This one is about 10" tall.

My first working clock from 2005.

Wheels have internal gears which tell the time. Not very accurate. But interesting.
That is about a 3 pound weight. 39" pendulum.

A mini model open wheel in acylic.
