I found and fixed the problem and the loom is working well. Thank you all for the suggestions. This is what I'm weaving for my first project. An 8 block pattern in turned twill, it uses all 24 shafts
I recently acquired a 1990 AVL 24 shaft production mechanical dobby. I had to take it apart to transport it. Fortunately, it came with detailed instructions so I was able to put it all back together. I have just finished putting on my first warp and tried to start weaving. The shafts lift they way they are supposed to, but when I close the shed it is not advancing to the next bar. Does anyone have any ideas about what to check? Is it a cable issue? A spring? I'm not sure where to start.
