    Default Re: the quest to get a mechanical 400 day to stay within a minute or so a year. (By: victor miranda)

    forumers,
    I have attempted to remove the apparent flutter from both clocks Bonnie and Clyde.
    they have kept time close to the timing I made of the pendulums.

    so tonight I regulated them to as close to 12 seconds as my stopwatch,eye, and reflexes could get them.
    each clock was timed over a 6 minute run.
    I expect them to be well under a minute a day. If they run faster, I'll assume I still have a flutter.
    ... they have never run slower than I expected, so I am looking forward to that problem.

    Perhaps they love you and flutter their eyes at you when you pass close by?

    Forumers,

    I have let the two clocks that are in this test go 5 days of running.
    they seem to each stay at close to their expected times
    Bonnie goes a little less than a minute a day fast and Clyde is the reverse
    a little less than a minute a day slow.

    I adjusted them. once I get each to less than a minute a week, I'll let them run
    and see If temperature affects the rate of the invar pendulum.
