I have been weaving a couple of years on my Schacht Standard with no mechanical problems. In the last few months, though, the second shaft sometimes-to-often stays up even when I release the treadle. If I tap it at the top with my hand or raise and lower shaft 3, # 2 falls down easily enough. But why is this happening? I did remove shafts 5-8 a few months ago because the numerous heddles on them got in the way and I wasn't using them for now. I have laid under the loom several times and pressed on the 2 treadle to see if I could find what is sticking, but am not finding any place where it might be rubbing against to make it stick. Any suggestions?
