New Haven Oak Kitchen Clock

September 9, 2007 | By | Reply More

I just finished a New Haven oak kitchen clock (my job no. 4333). The movement has 4 pillars and the dimensions are 4-9/16 x 3-1/4. The time mainspring is held by a separate short pillar attached to back plate. This movement has thin springs for time and strike. The two springs are both old but they are different, so I don’t know which one (if any) is original. The spring thicknesses are:

Time: 0.0165 inch

Strike: 0.0160 inch

This clock has nice old thin springs, and the pendulum motion is good, and so is the striking speed.

For future reference, some of the pivot diameters are:

T5F: 1.2 mm
T4F: 1.2 mm
T3F: 1.2 mm
T2F: 1.55 mm
