    .ExternalClass .ecxhmmessage P{padding:0px;}.ExternalClass body.ecxhmmessage{font-size:10pt;font-family:Tahoma;}First of all, I am fairly new to antique clock repair and only with mechanical movements.

    I have a replica of an old 1610 - 1640 rock clock made of wooden gears. Recently it stopped running and I noticed the top piece that normally swings back and forth has some type of suspension string or wire that is missing so it no longer runs. We can not find what ever was on it before, perhaps the dog ate it.

    I tied a piece of sewing thread on it and it tries to run, but will not keep running even with numerous adjustments. I am not sure what the original material was so I don't know if the sewing thread is the right thing to use or not, or if it should be some type of wire instead. Any ideas or thoughts would be greatly appreciated.

    Dan,

    Welcome to the message board! Any type of thread should work. You may need to adjust the length of the thread so the pallets mesh properly with the escape wheel teeth.

    As JEREMY advises, ANY kind of thread will do. Even fishing line as it is stronger and may last longer.
    I note also that the movable weights (called buckets) are missing from the wag arm. We can discuss them in detail later. Their purpose is to regulate the clock by moving them inward or outward on the arm.
    Without them however, with proper amount of driving weight, your clock should run VERY rapidly and gain a lot of time.
    So since it doesn't run at all without them indicates a major problem of some sort at this moment.
    Again as JEREMY writes, length of suspension string is not critical but must be short enough that wag arm doesn't drag on pillar below it. Otherwise you're good. Now if that is not the problem, as with any clock, it needs completely dismantled, thoroughly cleaned and reassembled with NO oil. NO oil because movement is totally unprotected and any oil ANYwhere tends only to gum it up.
    Let's start: How much does the big rock weigh? Does it have a MUCH smaller weight on the other side of the cord and how much does it weigh? I'm certain you are hanging the big weight from the left side?

    I b'leeve that, to be authentic, you'd use a doubled strand of horse hair. :D

    ALASKADAN has told me by PM that his escape wheel is warped. Of course that's a sure recipe for failure. I told him it can't be bought but if over his head - I've never made one - but for him, I'd try.

    Nope. Hair is hygroscopic. It changes tension and length predictably with the amount of moisture in the air. (humidity)

    Cotton or linen would be a better choice.

    For what it is worth, I found a pair of photos of what appears to be a "real" and once functional foliot timepiece in a set of Kodachromes from the 1960's. I believe the photos were made in preparation for an auction. 'Sorry for the fuzzy noisy pictures; it's the best my scanner can do.

    That may very well be th' real deal. Two wheels - three counting the hour wheel. Many iron reproductions of this were made before the woodens became popular but a discerning eye should be able to tell the difference. This one looks much like an original.
