I learned to make a jaw pulley from Al Stevens' Fred Project. Now that I use the same pulley axle for the crossing eyes, I've added another plastic pulley (on the left) and placed plastic washers on either side to keep the cords from hopping over the pulley. This time I added a copper wire across the top, similar to the Al Stevens method across the top of the jaw pulley (on the right). The cord in the jaw pulley is usually very taut. However the eye-crossing cords get slack when the eyes are moved side-to-side. This new set up will tame those slack cords.
