This can be a difficult clock restore as a result of it takes a while to dissassemble the motion, take away the barrel after which extract the spring. A brand new spring should then be wound to a decrease diameter, inserted into the barrel after which launched to a cosy match inside.
The image under exhibits the extracted spring and the brand new spring. You possibly can seet the distinction!.
