I am a new weaver. I purchased an older Macomber loom in October. I love the loom and it works well with one possible exception. I am not sure if the brake is working properly. When I step on the brake release it is still somewhat dificult to advance the warp. There is not much movement when I step on the brake release lever, it goes down about 2 inches. Is this normal? When I first started using the loom I had difficulty with the brake slipping so tightened it significantly. Perhaps it is too tight? I loosened it a bit last night but that didn't seem to help much with the advancing issue. Or maybe I am not using the proper procedure to advance the warp? I release the sprocket and just roll the cloth beam back with my hands.
