Help Clock hands keep tightening

[justinabshire]

This older clock I have keeps stopping because the hands keep tightening. I was unable to save the originals because of their age and because of that I put new hands which I had to put a plastic washer in but now it ticks for awhile then stops. I am just not really sure what I can do in order to fix the issue.

Both hands should be completely free on the shafts. That is, they should both have plenty of 'endplay'.

Your clock is an older one which usually has a minute hand with a square hole. This hand is held on its shaft with one or two large round nuts. The small outer nut, the one you see, is only there to keep the square minute hand shaft from falling off. Sometimes this outer nut has been overtightened to a point where the square minute handshaft is locked in place.

There is no place for a "plastic washer" that I am aware of.

Put the hands on in the order shown in the right of the photo, from left to right, hour hand-minute hand-large hole washer- small hole washer. Do not tighten the small washer against the large washer as you need a bit of play so the cannon can rotate.

The main thing is keeping the minute hand away from the hour cannon.

The main thing is keeping the minute hand away from the hour cannon.

Words of wisdom from Shutterbug. In the motion train, the hour hand and cannon have the most effect on the operation of the clock because they are furthest away from the source of power (whether spring or weight) and thus have the most torque multiplication.
