    As I noted, once it reaches the center of the pendulum rod,
    it does no good to keep turning is as it will start to make it
    slower again.
    It is a fine adjustment, though.
    If you can't get it slow enough by then, check the suspension
    spring carefully for cracks near the blocks.
    If not, the position of the bob can be adjusted. This requires
    taking it all apart, since it is threaded on the rod.

    I should note that it only ticks with no toc. On a timer with sound
    pickup it might be easier to set it at 5400.

    Didn't Kurt say,it is too slow? Maybe the pawl misses a tooth now and then.

    Quite possible Frank.
    If it has oil on it it is likely. Like I said, these clocks run fine without
    oil. I only put a tiny film on them to help protect against corrosion.
    It is the not anywhere near the amount used to lubricate.
    The pawl should have no oil on it.
    There are some adjustment screws but unless fiddled with, it shouldn't
    miss.

    When I first got it, I studied the action. I saw that the pawl was occasionally catching every other tooth. I adjusted it so that it catches only one tooth. Seems like if it caught every other tooth, the clock would gain an incredible amount of time.

    I made an adjustment not that long ago...I'm much closer after about 1-2 hours. I think it's starting to take effect.

    It always helps to keep a simple log and note the effect
    of each adjustment.
    Like most clocks, the weight adjustment is not linear.
    It has more effect per turn moving down and less effect
    per turn moving up.
    You are less likely to overshoot going up is you adjust based
    on the calculations of the log.

    There are at least a couple free electronic timer options.
    1) Clock Tuner is a free Android app.
    2) This one SEEMS stupid, but actually does work: http://mb.nawcc.org/showthread.php?1...ne-or-computer

    My weird tap on the screen or KB thing works pretty well if you have any sense of rhythm. It works in any browser that supports Java. PC, tablet, phone, whatever.
    Clock Tuner REQUIRES a quiet location so the only thing it hears is the clock you're interested in. It gets rather confused if you place your phone between 2 loud clocks!

    Sorry about the typo's. This was the first time I had actually posted from my cell phone. I was working on my wife's car when I saw your post.

    Thanks, Bill. I think Clock Tuner would be better if you buy the app...not ready to do that...can't quite make out what it's telling me on the free one. But the other tap on the keyboard program was interesting. I did that and was seeing maybe 53xx beats per hour, which is consistently slower than what Tinker said it should be, 5400 BPH.

    I found it interesting just how quickly that tapping thing zeros in on a consistent value. But it doesn't work very well for people with "tin ears." As a musician, it comes very naturally to me.
    Of course with THIS clock that doesn't tock, the calculated beat percentage is meaningless. It assumes tick, tock, tick, tock, not tick, tick, tick.
    I did a lot of reworking of a square dance tempo calculator to fine-tune it for clocks. I can't afford an electronic timer, but I DID buy the paid version of Clock Tuner. It was cheap enough for my budget. It does seem to work a little better.

    You said it was running slow. That is slow.
    All the Kundos are 3bps to my knowledge.
    My Haller clock is an oddball number.

    I've found that the type of battery can affect the time keeping by diverting some of the magnetic field.
    Original zinc batteries had no metal case but those dreadful Duracell types have a steel case which can cause problems.
    I have found the type that take a 'C' size cell are worse affected and have proved it by hanging the battery on fly-leads a few inches away from the clock after which the time keeping was fine.
    Another 'quirk' I found was that if I put several of these clocks side-by-side as close as possible, then after few minutes, all the pendulum(s) move together in harmony.
    This was most obvious with the German Schatz type.

    So, I've turned the adjuster probably 5 complete revolutions and the clock is still running the same amount slow. Do I need to take the pendulum off and fix something or is there another way to regulate the time on these clocks?

    Is it at the center of the pendulum?
    Are you logging changes?
