Kienzel German Wall Clock

In for repair is a Kienzel wall clock.  Upon initial inspection, the clock was missing side glass and would not run.  Further inspection after disassembly showed one of the mainsprings broke at one time and a repair was attempted.  More details below:

The side glass was replaced.  The glass used was single pane glass, custom cut.

The minute hand with the center bushing missing:

The minute hand attaches to the steel post not the brass canon pinion as shown below:

Some parts can be purchased and some parts can't.  This is one that cannot.  A new bushing was turned and installed.  The following images describe the process:

Here is the image of the hands attached to the clock movement 

Once the movement was disassembled, it was discovered that the mainspring was broken and riveted back together.  The only solution here is to replace the mainspring.  Fortunately, mainsprings are parts that are readily available at most supply houses.  This spring was purchased from Mile Hi Clock Supplies

After all work was completed on the clock, the disassembled movement was cleaned in the ultrasonic cleaner and reassembled.  The strike was tested, the speed was adjusted.  Once all the tests are completed.  The clock is ready to go home.
