Then the dreaded part rebuilding all the score reels, steppers and relays in the head.  Everything was going well until i rebuilt the player stepper unit. It didnt want to reset but with all those wipers i cant really blame it.  Everyhing worked when i left the wiper plate loose but it wasnt very accurate so i cut up an old stepper unit and used the notched washers to keep the disc further away from the unit but still allowing me to do it up tight.
