This design is a form of universal sundial. It is adjustable and we build it for its intended latitude.
The last of our songbird sundials has flown away. It now has a new home in a new country, in Paris. This special design appeals to the eye and has intriguing gnomonic features. The new owner already knew that the Orbdial was the one they wanted. Continue reading
The shadow of the ball on the sundial follows the sun all year round. The sun is low in the sky in winter, and it reaches its lowest point at the Winter Solstice on 21st December. This photo is one month later on 20th January. The sun is already higher in the sky, and the ball’s shadow has moved down.
Sundials catch a shadow from the sun. It is such a simple idea. The shadow on the sundial shows the sun’s position in the sky and the sundial reads it out as time, usually the time of day and often the time of year as well. Our armillary sundial is a special one with two balls that give the time of the year measured by the height of their shadow at noon. One ball casts a shadow in the winter months and the other one in summer. Continue reading
The sundial is in our client’s garden in North London. The sundial faces due south. We set it up at Noon on 28 November, using accurate corrections for the Equation of Time and local Longitude. The photo shows Solar Time at 12.30pm.
The world of solar time has fascinating ideas to explore. Our accurate sundial is almost a compendium of what a sundial can do. The client’s wish was something special for their newly created garden, and our design of a vertical sundial display appealed to them. Continue reading
A replica lighthouse sundial made in naval brass and copied in detail from a similar one held in the National Museum of Scotland at Edinburgh.
Our replica lighthouse sundial is complete now. We handed it over to its new owner, who came to collect it from us in Edinburgh in September. “This is wonderful,” he said. “It is even better when I see it than I ever imagined. This sundial will go right in the centre of my lighthouse display.” Continue reading
This sundial is delightful. It is the first piece of work by someone in Edinburgh who is learning to do stone carving. It is a very good sundial and they should be proud.
A sundial carved in stone is always special. This sundial is the first piece of work by a stone carver who has begun learning the craft of carving for their own pleasure. The result is very good. The rustic design suits the sunny spot on their slightly overgrown wall in the garden in Edinburgh so well.
Even a rustic design has to follow the sundial rules for the angles of lines on the dial and the angle of slope of the gnomon. Continue reading
After years of gradual deterioration outdoors the sundial was in poor condition. The Atlas figure was hard to recognise. This is an Art Deco design from the 1930’s. It has now come back to life as a working armillary sundial after complete restoration.
This armillary sundial was once in poor condition. It had been outside in the garden for a long time, and the owners asked us to restore it for them. The Atlas figure that supports the rings, and the arrowhead and tail, were badly tarnished. Continue reading
We shot this impossible photo blind because there is no room to stand between the sundial and the house wall.
Dihelion is our well-known dual sundial design, which reads solar time and solar declination. It is impossible to take this photo in the normal way because the sundial is too close to the house, and there is nowhere to stand. So the photo was taken by holding the camera against the house and shooting blind. At a first attempt, the picture has turned out well. Continue reading
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
