    Never posted here before..not really sure if this is the correct place concerning automotive clocks.
    Okay I repaired the clock in my 66 Tbird only to find it is running fast and its back in the dash.

    So over in the Thunderbird forum they tell me..."As far as adjusting the clocks go, moving the hands less than about 10 minutes has no effect except to change the time. Adjusting more than that will cause the mechanism to change. With a bit of patience, the clock will run correctly."

    Is this possible? I'm thinking we need to adjust the hairspring. I've only ever dealt with pendulums so I'm not sure.
    I'm going to try whats suggested and it was said by two others as well.
    Thoughts?

    I don't know for sure, but adjusting the rate of the clock by large adjustments in the position of the hands sounds like a fairy tale to me :) I think an adjustment of the hairspring is a much more reasonable idea.

    Launceston? my friend Wes lives in Launceston...Pastor of the Free Reformed church there.
    Yea ..I think it a fairly tale too but I'm going peel back the cover off the girl and set the clock a few times over the winter months here to see if it corrects it self.

    Some auto clocks have a gizmo that will move the rate adjustment when you set the clock.

    If it is running fast, each time you set it back it will change the rate a tiny bit until you eventually hit the spot.

    I say some clocks. If you have an owners manual for the car or a separate manual for the clock it may explain this feature.

    Most collector cars have a web site and many have an archive of manuals.

    That's the way many clocks of this period work. There's a stop on the stem that will engage the adjuster if it's moved far enough.
