Thanks Nino, I will give it a go.
The machine is having one of it's hissy fits at the moment and won't even eject a ball to start the game. It is sounding like the carousel isn't doing it's full thing. I will have to clean in and around it I think, there is a bit of grease and dirt around it - it was firing up fine a few hours ago. It isn't the first time it has happened.
Once she starts working again I will give the cardboard a go.
