Back Up

Restoration of Edward Korfhage and Son tower clock from Buer, Germany, c. 1950's.

Three train with hour and quarter hour count wheel strike. Combined cast iron flat bed with plate and spacer construction. Graham deadbeat escapement with adjustable pallets. Planet and ring gear maintaining power on all three trains. Movement is equipped with a 60 second, differential type, gravity driven train remontoire. Movement is designed to be both electrically and manually wound. 38"w x 55"h x 30"d.

This is to date the most complex tower clock I have restored. There are 579 individual parts. The condition as found was in fair condition as far as oxidation. Basically a B- on an A-E scale. This is, next to the completeness of the movement, the most important factor determining the difficulty of a given restoration. Total time to complete the project 276 hours; finished in May 2006.

All parts were stripped down to the bare metal; all traces of rust removed. Every square inch of the clocks' surface is covered by a protective coating (pivots and pivot holes excepted). All bolt heads and bushing faces were machined to obtain a damascene finish. This change, plus the fact that the overall finish is superior to that from the factory, are the only departures from the original specifications of the clock. I generally keep to the original specs, but do stray when I think that the movement's look will benefit from the change. They are usually minor. Below are some before and after comparison shots. The color is a close match, however, a flash was used on the before shots resulting in a color shift.
