    I have a nice 3-weight Vienna Regulator (or whatever it's called) and noticed one of the weights laying on the bottom of the case...the catgut had broken. I removed all three weights pending a resolution.

    I presume the choices are to replace the catgut in kind, or upgrade to the twisted steel cable. Any suggestions or direction you might have on this would be appreciated.

    hope no damage was done. purists will tell you to replace with catgut.... i'm of the opinion that i'd rather protect my clocks and have piece of mind by using braided nylon cord. i use dark/discrete/darker cords that don't stretch.... probably on the order of .7mm in thickness... from amazon.

    Thanks Bruce, I'll look into that. That sounds like a good way to go.

    someone asked me privately about this and here's my response... hope it helps.

    i use .8mm in my vienna regulator, .9 or 1.0 in most of my regulators:

    .8, multiple colors
    https://www.amazon.com/Pandahall-Beading-Knotting-Shamballa-Chocolate/dp/B01MYRVHOQ/ref=sr_1_2?dchild=1&keywords=.9mm%2Bnylon%2Bcord%2Bchocolate&qid=1588981500&s=arts-crafts&sr=1-2&th=1

    a good .9
    https://www.amazon.com/Mini-Blind-Cord-0-9-Polyester/dp/B01DMTFI98/ref=sr_1_1?dchild=1&keywords=1mm%2Blift%2Bcord%2Bchocolate&qid=1588981314&sr=8-1&th=1

    higher quality (and price) black 1mm
    https://www.amazon.com/gp/product/B00KX0129U/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

    another 1mm
    https://www.amazon.com/Mandala-Crafts-Replacement-Braided-Windows/dp/B01MSEF15Q/ref=sr_1_1_sspa?dchild=1&keywords=1.2mm%2Blift%2Bcord&qid=1588980984&sr=8-1-spons

    for clocks with heavier weights i beef up to 1.2mm (1.5mm can work on tall case clocks but can sometimes be a little thick). i put this one in two 5-tube westminster chimers last year and really like the quality... unfortunately it doesn't seem to be available at the moment:

    https://www.amazon.com/Pandahall-Beading-Knotting-Shamballa-Chocolate/dp/B01MYRVHOQ/ref=sr_1_2?dchild=1&keywords=.9mm%2Bnylon%2Bcord%2Bchocolate&qid=1588981500&s=arts-crafts&sr=1-2&th=1

    i don't have exact specs for you on how much these cords will hold, but when i initially researched it seemed like they would hold 75-100 lbs... minimum. given no rat's nesting (like gut) and no chinese torture metal splinters from frayed metal cords, i've been happy with my choice... purists, be damned. :cool:

    For the clock you have there, I would start the search at .030", pretty close to what bruce recommended. These published diameters are not very uniform and vary from one manufacturer to another, so expect some trial and error. If the

    Any breaking strength above 25# should be fine.
    Make sure the cordage is solid braid with some room left on the drum when fully wound.

    Metal cable for your clock is 'off the table' in my shop.

    I’m cheap. Before I ditched the mini-blinds, I removed the cord. There is a lot of it in a standard sized one and if you happen to purchase a new one, there is always way too much cord so I save the excess. Works well.

    I use radio dial cord. You can get it in several colours and I prefer it in black. It comes in diameters from .6mm up to 3mm. And, .8mm is my choice for weights around 2 1/2 pound. I have a single weight Vienna Regulator that I strung with it 12 years ago and it is showing no signs of wear or deterioration.

    Those are good examples of 'good cordage'. But, the mini-blind cord will be about 3 times too thick for this clock. Willie X

    I agree. If solid braid cord were available at the time these clocks were built, I have no doubt that is what would have have been used. It is far superior to metal in respect to wear and pliability

    I use natural (gut) badminton racket string on the best ones (other racket strings for larger ones) and when the customer requests gut, but otherwise I use natural colour synthetic racket string was about $15 at a local shop (also on Amazon) for enough to do a few clocks.

    Looking into this option...what gauge do you use? I weighed one of the three weights and it weighs 3.5 pounds.

    Roughly 20 gauge I think is .8mm 21 is .7mm and 22 is .6mm although it varies from manufacturers
    The tension on the rackets is 20-30 lbs so strength shouldn't be a problem

    Thanks for all the great tips. I went with the synthetic gut used for tennis and badminton rackets. It seems fairly stiff but once I get it in I'll know better. Got this on Amazon for $7.89US for 40 feet. Don't know when I'll get to this, but now I've got no excuses.
