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
Knowing the declination of the wall (WD) is important for designing a sundial. The basic calculation is azimuth angle (AA) minus protractor angle (PA) plus 90°. You can repeat your measurements for accuracy. Do ask for help if you are unsure.
“What is the declination of the wall for a sundial?” A stone sculptor asked us just this question recently . It is a good question because you must know the declination if you are making a sundial that is accurate for the wall. The sculptor was not confident about their own measurements and calculations so they asked us for help. Continue reading
The polyhedron is an upper part of the sundial with 80 dials, and an earl’s coronet on top. Four lion sculptures at a lower level carry dials in their claws.
In the extraordinary world of Scottish historic sundials, the supreme sundial monument stands at Glamis Castle. It is the tallest and grandest sundial and is in the grounds of one of the most beautiful castles in Scotland. In August 2020 a TV crew were filming there for a future series. They asked Alastair Hunter to Continue reading
The sundial consists of 61 multiple dials on raised panels and in sunken hollows. The date of the sundial is 1630. It has been made as an exhibition piece to show all of the sundial mathematics of its era.
In 2017 after almost four hundred years outdoors the sundial was showing serious signs of the stone deteriorating. The whole structure was feared to be unsound. Making it safe had become urgent. Continue reading
