Parts 1 and 2 of this series looked at the faults found in a c1785 long case clock movement. Now I start on the repair.

Before any work could be done on the bushes in the plates I needed to repair the barrels and great wheels. Here is the strike barrel great wheel mounted in a six-jaw chuck on a Schaublin lathe.

It’s been bored out true, a brass rod has been turned to a press fit into the hole to form a bush, and the bush is being skimmed back to the wheel thickness prior to centering, drilling and broaching the correct size hole for the barrel arbor.
