Summary

[edit]
Description

Pivoting tool, C.W.Z. brass and steel tool with screw knobs to operate tool, U-shape with rods that meet in middle. In black leather box with red velvet lining. 6 extra rod pieces in box. If a pivot of a watch wheel became broken or worn, it had to be replaced. This entailed drilling a fine central hole into the end of the shaft for fitting a new piece of steel tightly into it. This was then shaped and polished as a new pivot. Of recent years this would be done in a watchmakers lathe, but in earlier times it was done using specially designed tools such as this, or a larger tool known as a Jacot tool. The work was revolved using a bow with a fine thread running around the pulley, in exactly the same manner as with the watchmakers turns. 

Part of the Applied Arts and Design collection.
