H3 Clock with Remontoire

The John Harrison Meccano H3 Clock.

This a very advanced Meccano clock, loosely based on the Copley Clock by Dr. Michael Adier, ModelPlan 157, in which the author was involved.

In this Meccano version of the H3, because the Meccano system does not include a large clock spring, it uses a small 16 volt, geared, 200 rpm Greenweld electric motor running on only 4.5 volts.

• The Main Frame

• The Drive Bearing Assemblies

• The Air Vane Drive and Lower Air Vane Bearing Assemblies

• The The Low Friction Bearings and Assemblies

• The Remontoire 'Spring' Carrier, Driving Arm Assembly, 'Spring'
