Anonymous created the topic: Sessions Mainspring Size
I need to know how to determine what mainspring I need to get. I have a Sessions mantle (box case) hourly chime and 1/2 hour ring. Can you help me get this going again. Had it running for about 4 hours when the mainspring totally self-destructed. Now there are parts of the spring all over the shop. Boo hoo! Any assistance would be appreciated.
The spring in the clock is 3/4" wide. I've attached 2 pics one shows the mackers info the other shows the entire movement.
Then I'll need to know how to replace it without ruining the clock. Please.
