So, I finally have my Macomber all ready and have woven almost 10 inches on it. For the first 3 inches, I noticed my warp was getting loser as I wove. A quick check made me realize my dog wasn't staying put in the ratchet (I think those are the correct terms). But, if I put it there, it stays put until I advance the warp again. I've also noticed my brake treadle tends to get stuck on the front beam/beater bar if I'm not careful. Pretty sure this is not causing the problem though.
