Arms motor

This pic shows the 'Single Rotate Device' that is used to raise and lower the feed arms. Again, not a very good pic due to its position. The final output shaft is used to turn a sprocket in a 2:1 drive to the cranks that are linked to the feed arm push rods. The limit switch that can be seen towards the bottom left of the picture, is hand operated by a long rod that pokes up out of the top, and is used to either raise or lower the feed arms if they happen to be out of sync when starting up the model.
