Hi Guys 

I am working on my first stopwatch, and have come across a snag that likely has a simple solution but it seems to be escaping me..

I am refitting the dial and hands to the movement, the sub dial works fine but the larger sweep hand does not seem to engage or move at all. 

Any advice with installing dial and hands onto the stopwatch movement? 

Many thanks in advance. 

Cheers

Dave

You have an interesting problem And a interesting picture? Normally with stopwatches you do not remove the hands. Remove the dial and the heart-shaped cams are supposed to have spring is on them that go on to the shaft the drives them and the whole thing comes off. He is still seem to have the shaft stuck in the heart-shaped ham which is different than what I'm used to seeing?

Here's a link to a picture of what talking about Sonoran with a dial comes off the heart-shaped cams would go with the dial and heart-shaped cams would have little spring is the hold onto the shaft

Did it work before you took it apart?

Hi John, thanks for getting back to me. 

The stopwatch came to me from a friend with the dial off but the movement in tact and running, the shaft was separate in a small container. So far I have only attempted to put the dial back in place and then push the shaft down through the center of the hand. However, that does not seem to improve the situation, perhaps the shaft is damaged

Or the shaft goes into the movement before the dials/hands. 

I will have another look this morning. 

Thank you 🙂
