Preservation of James Harrison Turret Clock at BHI October 2001


James Harrison made this clock in 1844. It is a birdcage, two trains and with Harrison maintaining power.

The measure is 90 x 71 x 126 cm (WDH) and the weight is more than 200 kg.

It was originally fitted with a special made gravity escapement, but someone removed this and put in an ordinary pin wheel escapement.

This clock has been stored in BHI stable house for some years, and for the time being we don't know where this clock came from.

Due to the fact that this clock will not go back to a tower, what we did was mostly preservation. We did not use blasting or acid, only elbow grease.

Three students, the instructor and his assistant did the preservation which took one week. If we should do any necessary repairs such as a new pinion, escapement restoration or making a new pedestal so the pendulum could swing, we would need some more weeks.
