I love my Jane loom but a few projects ago I noticed the beater wasn’t quite hitting the fell squarely. At first I thought it was me, so have been quite careful to pull the beater forward at its centre, but I’m still seeing a slant. On a 20” warp, the left side is almost 1/4” higher than the right. I wonder if there is a fix to bring the beater back into square? Or am I fussing over nothing?
