i will try to find some pictorial later when i have the time as i have to do some work now ...
you have to confirm the hands are loose when fitted. You can try slightly moving the hand after being fitted to confirm if it is loose.
The CP is fitted to the first wheel in such a way that it is allow to slight "somewhat slip like a clutch" but not overly loose ... If the hour hand is moving normally and the minute is not, then you need a staking tool to "tighten" up the CP.
dont file/sand off the bottom of the minute hand ... you may end up with minute and hour hand rubbing each other due to lack of clearence between them.
Get a cannon pin tat is 3.15 mm like here http://www.tztoolshop.com/page151.html
however you can find such sligtly higher CP in asian 6497 like those in rep watch.
I pretty sure at the back of my head there is a differnece between the 18 kbph and the 21.6 kbph .. gearing size is not the same.
hope this makes some sense to you and able to help u.
cheers
