Hmmm... This reads like the best answer. I'm not sure I understand - I think I tried this. When you wrote, 'Squeeze the plates together', did you mean squeeze the sides of the links from the left and right sides between the pins? Or did you mean squeeze them together from behind the pins? Squeezing the plates together while pushing the ends together reads as though it requires 3 hands? Are you perchance an alien?
