Thanks for the reply,yes its the cable that rotates the chute,in the picture there is only one hole going through the hand crank shaft and the cable mounts on the chute are mounted off to one side
Your problem is that it is too simple
Run the cable through the hole in the crank. Have the hole in about mid point of the cable.
Point the chute straight towards the rear.
After the cable is passed through the hole in the crank, you now have two cable ends.
Wrap the cable in opposite directions around the crank shaft 4 turns.
Wrap each end of the cable around the chute in opposite directions and then put both ends in the clamp on the chute.
As you turn the crank, the cable in the hole will pull on one side of the chute causing it to rotate, while the other end of the cable will unwrap on the chute as it turns.
