A 30 year old Tools of the Trade table loom with floor stand was donated to a group I work with. It was completely disassembled, but the original instructions were included. We have been slowly putting it back together, sort of like a jigsaw puzzle. When we follow the original instructions for tying cords to shafts and then running the cords down to lams in floor stand, the loom does not work smoothly. Does anyone have experience with this loom and how to put it back in working order?
