What makes a clock a torsion clock?
Ed
The spinning pendulum on the bottom.
Dad was trained as a watchmaker in his younger years. He carried this on throughout his life, making parts and repairing watches and clocks on the side. Mom just recently got rid of most of his stuff, including a tiny lathe, a machine that timed watches and various tools. He never made it a "real" business, but word spread, and he always had a project on the bench.
He did one torsion clock which he fought with for a long time to get set right and vowed to never take on another one. There are still a bunch of strange clocks in the basement that he bought over the years because he liked how they look.
A torsion clock has the pendulum hung an a thin torsion spring usually 4 thou or less and it spins one way then the other , unlike a pendulum clock that goes left to right.
Some people call them anniversary clocks or 400 day clocks because they run 1 year on a single wind .
I have repaired quite a lot I love doing them although they can be frustrating at times and it keeps me busy in retirement.
