Wire                                                                             Latest change 2019-12-15

I use piano wire of 0.75 mm for the pendulum at home, and 0.925 mm (gauge 16) for the pendulum in the chapel.

As piano wire has a good remembering of being rolled up during shelf time there may be an effect on the pendulum's behaviour. I intend to investigate that by rotating the top clamp and see if there is any difference in the pattern of CW- and CCW ellipse. That investigation will take many days, perhaps weeks, and is planned for winter 2017. (dec 2019: still not done)
