    Hello all,
    any recommendations for the type of rope that can be used in a 30 hour long case in which the rope passes over the drum in a "valley" that has grooved sides to insure that the drum has a "pinch" to prevent the rope from sliding through. Just imagine a drum with spikes in the bottom that would normally pierce the rope - no spikes in this one except for a "V" shaped valley, the valleys of which are grooved.
    I've tried cotton sash rope but in a short time there's so much lint and fuzz built up that the groove quickly looses it's ability to grip the rope. Linen would be better or polyester? And a source for the correct type would be appreciated.

    thanks, jim

    I have a few wooden gear Foliots that have the same type of V groove pulley set up. When I was searching for rope for those a friend sent me some of this Venetian blind cord he brought from a hardware store in Texas. I think it comes in different diameters as well. It works well for my purpose, but I have no experience using it in a Longcase.

    John Wardle in the UK do a linen clock rope for 30 hour longcase clocks that might suit. It is 11.5 feet in length and sold in various diameters, 5 to 8mm, it is not expension. Rope does by its nature produce more dust.
