Restoration 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 sometime someone removes this, and put in an ordinary pin wheel escapement.
This clock has been stored in BHI stable house for some years, and for time being we don't know where this clock came from.
Due to this clock not will go back to a tower, we did mostly preservation. We did not use blasting or acid, only elbows grease.
3 students, the instructor and his assistant did the preservation during one week. If we should do necessary repair, (new pinion, escapement restoration or repair, making new pedestal so the pendulum could swing), we would need one more week.
