Hello! I purchased a used Schacht loom and am having toruble with the tension. Until i got my hands on it, it hadn't been used in five years. After threading it, as soon as I step on one of the treddles, it loses tension. The front beam doesn't seem to be moving, I think it is the back beam that releases the tension. Could the brake cable be worn out? Is there a cheaper alterntaive than ordering a brake from the Schacht website?
Thank you for any and all help!
