HELP. Does anyone have any ideas how to align the minute hand to strike at the correct time?
The centre cam seams to be in the wrong place.

Hi Robin. What type or name of movement are you dealing with?

Not sure of the spelling, but it looks like Kienzle
It's a large carriage clock with Westminster chime, stands about 300mm high

Robing, take a look at the minute hand, does it have a brass collar where it mounts to the shaft?

Hi William
Yes it does, but I was worried about breaking the hand if I tried to turn it.

Thanks for the suggestion. As resetting the centre cam would be very difficult.
I was thinking of filing a square on the end of an appropriate size drill, to hold the centre, but was not sure if it was supposed to move at all.
Will let you know how I get on.

Better have someone check me on this, heck I forget my name sometimes :roll:

The center cam is not what would need to be adjusted on a rack and snail movement. It seems like that would be it but all adjustment are made thru other pieces.

Here is what I use to adjust the hand collets so the minute hand will be on time. http://timesavers.com/i-8947503-clock-h ... -tool.html
It works quite well and will put it in a vise at times if the hand is being stubborn. Most times though the hands will turn easily without the vise. I would not as William said do any adjusting on the rack and snail. You could be getting yourself into trouble there. I have never had to make a adjustment on snail except to make sure the count rack tail fails in the proper place on the snail so you get the correct count on the strike.

Hi all
Have not had time to try your suggestions yet, but I'm glad it's not the centre cam.
Will post with my results soon.
Thanks again
Robin

Hi William& Bernie
Thanks for your comments, I made up a tool and all went as you suggested.
Much easier than my first thoughts.
Thanks again
Robin

Just thought I would add this post script.
After all this, went to fully wind the clock, and the Spring slipped for the hour strike drive. Which was what I was replacing in the first place.
Oh well back to square one.
Robin
