Tie-ups are used to connect the lams to the treadles of a loom. On more modern looms various labour and time saving methods have been devised with which to do this. But on older looms there is often simply a closed screw eye loop on the lam and another on the treadle. There is nothing on the internet to show how these were originally installed. In Oscar Beriau’s book, Home Weaving (both 1939 and 1947 editions) this method is illustrated. The use of cotton cord is originally used since hardware only interferes with treadle movement; any added hardware installed on an older loom is an upgrade for the sake of convenience and should be removed.
