I would like to thank you both for stopping me making the biggest blunder. I am totaly embarased.Let me tell you a story. Every Tuesday on our way to my motherinlaws we call in at a communal farm, kids with learning difficulties work there. What a great job they do there .Anyway a couple of weeks ago I took some of my pieces for these younge guys to put in there canteen and on going today for our eggs the man in charge asked me if I had made any more, to which my answer was my saw had broke down and I had not had it longe, he replied by asking if it was a drive belt to which I said there was no drive belt and then I thought the bolt that held the arm on!!!!mmmm your right it had worked its way off uuuuu brain dead me . So problem solved.Mal
