setting up an orco 74
I have been trying to assist my new weaver friend to get her vintage foundling Orco 74 going well. No directions or diagrams came with it. The question then is how to configure the rear brake to do it's part to tension warp. The previous owner had used a spring and a heavy cotton cord. The path of the cord is not evident. There is no ratchet and pawl system included. I can't find images of this part of the loom to use as a template. Can someone provide directions or images?
