This is our new sundial design. It stands in our garden among the plants. It is early morning and the sun has just reached the centre band where you read the time.
An armillary sundial has a wonderful form. It has mathematical rings creating beautiful shapes with circles and lines. The sundial in the photo has just begun to catch the early morning sun in the garden.
The sundial gnomon is the slanting rod in the centre of the rings, and the wide sweeping band is where you can read the time. These features are the same as other armillaries, but our design has special secrets. Continue reading
Details for making the sundial came from archive records and photos. This image shows the design and successful first assembly of the new parts.
The replica of a 19th century lighthouse sundial we are making will be part of a mobile exhibition. It is progressing well. Lighthouse sundials were made by skilled instrument makers, who worked mainly with hand tools. We are using modern techniques for cutting out the metal and etching the intricate design on the dial plate. The picture shows our first trial to assemble the dial and gnomon parts. Continue reading
This is the finished artwork for creating the sundial plate. The graduated lines and gnomonic information will be transferred onto a prepared blank plate using the technical process of photoetching.
For centuries, the lighthouses round the rocky coasts of Britain have been a lifeline to ships at sea. The lighthouse keeper used a sundial to find the time. It was part of lighthouse equipment before telegraph, radio and automation eventually took over. We have been asked to make a replica of one of these sundials.
The replica is for a travelling display of Scottish lighthouse memorabilia, which the owner will use when he gives one of his regular talks on lighthouses to interested groups of people. He has built up a significant collection of items but a sundial is an essential missing piece he has been unable to obtain so far. Continue reading
Time lapse camera set up for study of a sundial looking at precision of the time shadow
There are many interpretations of how well a sundial reads the time. It is often thought the smallest increment of time on a sundial will be around two minutes. This is because the large diameter of the sun gives a fuzzy edge to the time shadow. Our study looked at the shadow Continue reading
