hairspring

by electrichorologist

 

Technoguy,

It would keep the cost down.

It would be easier if it had the removable hairspring stud to adjust for the height of hairspring. The hairspring and isochronism is not critical in an electric; however, the hairspring still has to be level and the coils not touching each other.

The balance assembly was taken from a donor movement, the regulator was bent down, making a difference in the dial up and down positions of 2 minutes a day. This was corrected and dial positons are within 5 seconds a day of each other, also the hairspring had to be leveled and tweeked.
