i have a pretty old mira cb 4 harness loom. i have woven a few things on it, but am still having trouble. it has great tension on the warp. my trouble is getting any kind of shed. i can depress the treadles with some difficulty. it is harder to depress the treadles on this than on my jack loom. also, the shed is poor. i have replaced some of the cords on it that were fraying. the rest are the ones that were used by the last weaver. if i replaced the cords from the treadles to the v shaped thing that connects the treadles to the lamms, and made them long enough so that the far edge of the treadles touched the floor, would that solve the problem? i love this little loom, and i would like to get it to work better.
