After threading this I got the nut on but now can't get it off anymore. What to do???View attachment 25819
No sewing machine used to make this so no seam. This time photo done with phone with bright sunlight so a bit too much contrast.Move it over a bit so the seam shows.
Or unthread the shaft from the hidden joints at the ends.
Or just saw it in half and throw it at the sadist who made it.
