I purchased an older Harrisville Loom, that I'm in the process of setting up. In the process of converting this to a six treadle loom, I noticed a broken leather cable and I have no idea what it is supposed to connect to. There is a small wooden rectangular piece at the bottom of the right hand side, in the back of the loom, and the leather cable is currently connected to that piece, but the top of the leather cable has snapped off wherever it is supposed to be attached. I would appreciate any help in knowing how I need to reconnect this piece. Thanks in advance for you help!
