Projects to make your own dials
Update Mar 7, 2021. We regret that, due to an oversight, four submissions from Tim Chalk were not published previously or included in the following summary. This has now been remedied and we apologise for the delay.
This, the sixth scheme, has had a record number of entries, boosted in part by time available due to the COVID-19 lockdown. Visitors to the website are encouraged to submit comments on any or all of the sundials, using the reply box at the bottom of each page, on aspects such as design, craftsmanship and overall function of the dial. These comments will help the Trustees to choose the entries for particular Awards.
In summary, we have a large ‘monumental’ dial in Malaysia; a restoration of very old polyhedral dial; a ‘first venture’ to commemorate a ruby wedding; the restoration of a stained glass window dial; a number of dials (conventional and unconventional) by experts in Cambridge; an obelisk for a garden in Cornwall; a novel altitude dial linked to human activities rather than just the hours, and a number of precision dials of different types cut in slate.

Battle of Britain – 80th Anniversary
Rotating polar mean time dial
The Socrates Plato dial
Battle of Britain – 80th Anniversary
Because of my interest in flying and 2020 being the 80th anniversary of the Battle of Britain, I decided to design and make a west facing dial to commemorate the event. The dial is slate, 600mm by 480mm x 20 mm thickness. The knowing of time is a very important aspect in flight whether for navigation, fuel management, or coordination between air traffic.
An unusual submission to the 2020 BSS Sundial Design And Restoration Awards from the team at Tool/Toy Project.
This is the Circadian Yardstick, part of a collection of instruments made by Tool/Toy Project in 2019 for the Oslo Architecture Triennale. The collection consists of a set of objects designed to slow down the daily domestic routine by encouraging regular playful interactions with the Sun in the home. The devices engage the senses, encouraging various ways to listen, touch, watch, meditate, navigate and dance with the sunshine and its effects.
The Circadian Yardstick works by measuring the length of the shadow of a pin (gnomon), which in turn indicates what our bodies are doing according to our circadian rhythms at various times of the day – from peak alertness to an enhanced sense of smell. By intellectually connecting our internal cycles to those of the Sun, the yardstick encourages the user to live in harmony with both.
I’m sorry to say that the 2021 Solar Data Card included with the December Bulletin contained a number of inaccuracies, all due to an oversight by me and in no way reflecting on the accuracy of the information kindly provided by Fiona Vincent. Apologies to her and to members for the mistake. A corrected version will be included with the March Bulletin and is provided here as a PDF which can be printed on a single sheet of A4 and folded to provide a two-sided A5 “card”.
BSS Zoom Event
In lieu of our 2021 Conference we plan to host three talks via Zoom on 17 April 2021. They will start at 17:00 BST and expect the entire event to last about 90 minutes. This time of day should suit those living in any time zone from the west coast of North America to the Middle East.
The speakers will be Fred Sawyer (President of NASS), Roger Bailey (sundial designer and former Secretary of NASS) and Woody Sullivan (Professor Emeritus at the University of Washington and instigator of the first sundial on Mars), all of whom are well known to those who attend our Conferences. We shall provide titles for the talks in the new year. Meantime, Fred has promised that there will be no equations in his talk!
If you would like to attend please email firstname.lastname@example.org. You will be sent an acknowledgement and, later, a formal Zoom invitation. The event is free and open to anyone.
Many people have become very familiar with Zoom over the last few months but if you have managed to avoid it so far and would like some help, please read on for guidance on both its use and how to install it, kindly provided by BSS member Mike Faraday, as well as an offer of 1:1 assistance from Frank King.
