The Ashford loom I just bought is already giving me problems. The rachet & pawl has failed twice now, allowing the warp to come loose. Since I was working on a test & practice project, it wasn't a big deal. But when I make a larger project, a ratchet failure will be a Big deal. Anyone have any suggestions/solutions to fix the rachet/pawl letting go problem? The tension is tight enough to weave, but it came loose in the middle of a run.
