How in the world did a small thread get into the movement ?
Unbelievably this gear came out of the movement like this . My customer said it was running for years . All I do to straighten it is tap on it with a small brass hammer. Rotate , tap , rotate , tap ..... I use my cell phone camera for these pictures so some are better than others .
In this clock you can see the lantern pinion is rubbing on the right hand side of the wheel that drives it . I moved the lantern over so it's now being driven in the middle of the cage .
This all of the parts to a grandfather clock . Each one will be inspected before assembly . Very time consuming work . I look for wear and bent or cracked gear teeth . Bent or worn pivots ( that's the part of a gear that passes through the front or back plate ) . Also rust is a factor too. I sit down with a loupe and check each piece . Then put it all back together.
