Retropin wins this time. I am glad it wasn't the bigger job Strangeways. The ball stepper unit was jambed up a little. Once I moved the wheel it clicked and seemed ok from then on. I checked the mounting screws thinking it was misaligned but all tight. Cleaned with electric cleaner and all is working well now thanks very much to you both. I have attached a photo of the stepper. Strangeways, if you want, I can copy those drawings and send you back the origionals that you very kindly sent me?
Anyway, all the best for Australia Day to you both and to all!
