But I didn't say clock hands, though. I said clock springs.
Those are the things that, before the days of quartz movements, stored the energy to make the hands go round.
If you can find an old mechanical clock of the wind-up variety, it will have at least one spring in it, maybe two if it is an alarm clock.
The spring is usually contained inside a brass case which you have to take apart. One of the main downsides is that when you uncoil the spring, it doesn't. (Uncoil that is.) So by default you are going to end up with bent picks. But with care, you can straighten out a piece of the spring by bending it in the opposite direction to the normal bend.
Unfortunately I don't have any springs to experiment with any more because all my junk got thrown out when I moved.
By the way, anyone else have that problem with women? "What do you need all those old scraps of metal and wood and stuff for? It's junk--throw it out!"
