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
“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
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
Lews Castle at Stornoway on the Isle of Lewis in the Western Isles is in the far north of Scotland. It once belonged to the wealthy overseas trader Sir James Matheson, who built the castle as a mansion home on the site of the ancient Seaforth Lodge in the 1840s. He planted woodlands to surround his property and laid out pleasure gardens with species imported from all over the world. An extensive programme of work to regenerate the castle grounds began in 2019. When an original cast iron pedestal was discovered at the castle it was decided it should be restored. It now has a new sundial, which is just finished, and Continue reading
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

Summer Solstice 2020 in Edinburgh was a day of beautiful sunshine. What could be a better time to show off our Dihelion dual sundial, which can read the solstice and the equinox seasons and the daytime hours. Shifting patterns of sunlight and shadow and petals of the sunflower show through so clearly. There is a lovely Continue reading
The sundial obelisk at Drummond Castle in Perthshire has a long and distinguished history. It has its place in the architecture of the ancient castles and houses in Scotland. It is connected with the very earliest days of the British Sundial Society (BSS). And it is one of the most important free-standing sundials in the British Isles from the early 1600s still surviving.
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
