In Ralph’s photo he had some drawings of circles behind the umbrella.He told me he would like one of these to be the Sun. We decided that they should form part of some crazy clockwork. A few days later I found some gardening mats that were shaped like sunflowers. The edge of the petals formed perfect gear teeth. I tried to get them to mesh but unfortunatly they were not perfectly circular and would not work as gear wheels ( Although they did come tantalisingly close). Undaunted, I used the profile of the petals as the teeth of my own ply gear wheels. I am hoping thet Mr Steadman will provide some lovely sun flower art work for the large wheel.
