Sundial blog post updates

BSS Bulletin archive available online

: Webmaster

The BSS Bulletin archive, previously published on CD, is now freely available on the website. At present issues from July 1989 (the first Bulletin) to December 2010 are provided as searchable PDFs. Members may be interested to see the original front covers from the first three editions since these went out of print quite quickly and were subsequently republished with the current cover design.

The archive page has two tabs: each issue is accessible via its thumbnail on the Volumes tab and the Articles tab has sortable columns for author, title and volume as well as a free text search for titles.

These 76 issues with nearly 1500 articles and more than 3500 pages of text represent an unparalleled body of knowledge about sundials which the BSS is pleased to make widely available.

BSS Virtual Conference – follow-up

: Webmaster

A number of people have requested to see the chat discussion from the recent virtual conference: it is now available as a PDF or text file.

The full responses to the SurveyMonkey survey are also available, apart from Q10 which contains contact details for the people who entered the draw for a free annual subscription to the BSS. Thanks to all those who left feedback and who entered the draw: the winner, drawn at random, was Martins Gills. We will be in touch with him to confirm the details.

Update #2: BSS Zoom Event – 17 April 2021

: Webmaster

We successfully held our first Virtual Conference via Zoom on the 17th April and were joined by about 150 participants from around the globe. Feedback about the event has been extremely positive and all the speakers – Roger Bailey, Woody Sullivan and Fred Sawyer, with the event introduced by Frank King – were very highly rated for their fascinating talks.

The full video of the session, lasting a little over 90 minutes, is available here:

Although the vast majority of participants were able to enjoy the session, unfortunately a small number of people did not receive the joining instructions. We hope that the video above makes up for that and we have taken those issues, as well as the large number of comments and suggestions, fully on board. We will provide information about how we plan to proceed in due course but there is clearly an appetite for more events like this!

Four Dials by Tim Chalk

: Webmaster

Tim Chalk submitted details of four dials to the 2020 BSS Sundial Design And Restoration Awards
well before the end of the competition but due to an oversight they were not added to the list of entries or the web site at the time. Apologies to Tim for the omission and we encourage visitors to look at them. They have also been added to the full list of entries below.
The four dials are:

Update: The 2016-2020 Award Scheme – summary of entries

: Webmaster

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.

Four Dials by Martin Jenkins

: Webmaster

Martin Jenkins has clearly made excellent use of his time in 2020 and has, just ahead of the deadline, submitted details of four dials to the 2020 BSS Sundial Design And Restoration Awards

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.
