It's interesting to think about how they would calibrate the pendulum. Imagine having that job? 🤣👍

You can calculate the force needed to move it to get done sort of scale. Got to get the chemical mix right for predictable results. Someone I know used to get stuff from them when he worked in a slate mine. That was a big industry there, but not now.
We haven't been to Wales for years. It has a lot of industrial history for sure. We visited an coal mine that had been converted into a museum. Terrible working conditions for the miners back then.
