Data from Turret Clock available

This month’s Horological Journal includes an interesting link to the remote monitoring work by Prof. Hugh Hunt Professor of Engineering, Dynamics and Vibration at Trinity College Cambridge.

The barometric compensator is really neat

Agreed, Duncan … but I was a little surprised to see this note:

”Side view of the compensator attached to the pendulum. There's a bit of a wobble on the pendulum - needs straightening out.”

When I thought it would be obvious to a ‘Vibration man’ that the wobble is more on the stack of aneroid capsules.

As far as I can remember the aneroid stack is solid with the pendulum so it’s definitely a pendulum wobble. I’ve seen the clock a couple of times and it is very impressive.

regards Martin

bottom member of the compensator, which is clamped to the pendulum, seems to have a rotational movement. as it's clamped to the pendulum that must have the same motion. Odder and Odder. Might just be an optical illusion of course.

Indeed it might … Strange things happen on web-cam videos

But it certainly looks [to me] like the stack flexing.

Might have been a Fred Dibnah episode about Big Ben

They used old pennies as temperature compensators on one of the weights

Ady1. They used pennies as temp. compensation on pendulum. I use 8BA washers on my Regulator for same purpose
