A Sundial Mural Competition
Hello Sundialists, We are a small group in Bellingham, WA. that have created an exciting mural competition for a very large two story wall in our historic downtown. We are reaching out to a multitude of international communities in pursuit of receiving submissions for a visually striking mural that also acts as a sundial. This multi purpose art project is not limited to people who specialize in the field of gnomonics, those without previous experience may bring some fresh ideas to the table to this ancient art form. We understand that some people may want to submit a design and do not have the ability to create the final product. If that is the case, there is a monetary award for the winning design. However, if someone wishes to install their design we are accepting budget proposals to accompany the submission so that you have control over the final product. Bellingham is a hidden jewel of Washington State filled with people who are forward thinking and enjoy the outdoors. Protected by the North Cascade mountains and bumped right up to the bay, our views are speckled with island's, volcanic mountains, numerous lakes, thick mossy forests, and are surrounded by small farms. Our city thrives on small businesses which fill our brick buildings thanks to our community which encourages handmade and locally sourced goods. Bellingham is very unique, and we hope for the designs to reflect this vibe. For all the information regarding this competition, numerous inspiring pictures, as well as submission forms, visit our web page here: http://www.alliedarts.org/sundial-mural-competition/ Thanks for your time and the best of luck, Sasch Stephens Coordinator The NW Sun Works --- https://lists.uni-koeln.de/mailman/listinfo/sundial

RE: Metal cone
Hi Dan, you didn't say how big you were looking for. For small sundials you can use the cone used for jewelry display to hold rings and bracelets. They are even available in clear plastic. sasch stephens Date: Sat, 15 Aug 2015 21:16:41 +0300 Subject: Metal cone From: cerculdest...@gmail.com To: sundial@uni-koeln.de Hello all !

RE: Print-shop sundial for outdoor use
Thanks Dan, I like the simplicity of the application. Questions: Are the lines and numbers on a sheet or applied individually? What is their material? What makes it waterproof? Thanks again. Sasch Stephens Date: Fri, 10 Apr 2015 17:50:43 +0300 Subject: Print-shop sundial for outdoor use From: cerculdest...@gmail.com To: sundial@uni-koeln.de Hello, I wanted to see if I could make an outdoor sundial from materials available at a local print shop. You can see the result in the attached photo. The vertical flat board is an alucubond panel 50x60 cm in size. The hour and date lines, numbers and text, all have been printed together and glued onto the board like stickers on a car. For the design I used Orologi Solari and Delta Cad. The gnomon is made of 1 cm thick white plastic cut to specification, the kind used for making volumetric letters in the advertising business. It's glued to the board and also secured by two small screws from the back. The gnomon is really 2 pieces: one part is a base triangle, the other is a circle and rod which is glued over the first part. The circle has a hole which lets the light through. I was not satisfied with the light spot I got at extreme hours so I trimmed down the circle plastic thickness to 5 mm using a cutter and an open flame (wish I had an electrical hot wire for this!). Unfortunately I messed up while fixing the sundial to the wall - the upper edge is a little off from the horizontal and consequently the time is also off by a few minutes. Total project cost was around 35 USD. Have a nice and sunny weekend! Dan UzaRomania --- https://lists.uni-koeln.de/mailman/listinfo/sundial --- https://lists.uni-koeln.de/mailman/listinfo/sundial

RE: Most Valuable Sundial?
Hey guys, regarding Chinese sun instruments, I was just looking through the catalogue from the exhibition I organized in 1985 in Beitigheim, Germany called 'Zeit und Sonne'(Time and the Sun). Included was a picture and reference to a 50 foot tower in China built in 1279. There was an opening at the top which allowed light through to shine onto a bench which extended 120 feet out from it, I assume to measure the noon hour angle, hence solstices and equinoxes. It's listed as the Tower of Tsou Kung in Kao-tseng, China. The spelling might be a bit off since it's from a German translation. I tried to find reference to it on the internet, but on short notice wasn't able to.

Hw can you see a shadow on transparent glass? Does it project to the surface? There are two equatorial discs in the Imperial palace in Beijing. I saw one in '92 and have seen photos of the other one. The Chinese were intrigued by western mechanical clocks but other than the instruments at the old observatory set up by Jesuits in the 16th century, there are not many sundials in China and the far east. Time was not of the essence long ago and far away. I hope someone can prove me wrong. Regards, Roger ps.

Or do shadows project down onto the ground? I have not seen very much about sundials from the Far East, if it is still OK to call it that.

I made a sundial with flower-beds in the hour segments but did not attempt to find the clock opening or even sun following flowers. I believe I showed this at the NASS conference in 1999. What I found most difficult over time was merely finding plants which would stay low enough not to shade the hours next to them. I noticed that the list included some relatively tall plants. Is it possible that the shading of a large blade gnomon might enhance the opening delay or early closing of certain flowers??

RE: Magnetic Gnomon (design 1)
Hi magnet enthusiasts. I'm glad to see the interest in this simple solution to the centuries old gnomon/glass problem. I've been using supermagnets as gnomons now for over a year and have considerable hands-on experience. I've been using mostly 3/32 x 7/16 magnets, one on each side of single pane glass. The gnomon is a simple steel rod painted with rustoleum and cut at the appropriate angle. A wood or plastic bead serves as the indicator for the 'equation of time'. My experience with the stability of the gnomon is that if it is cut precisely and is not too heavy that it will withstand considerable wind without moving. I actually like the fact that it might move slightly, reminding the user of it's presence and affording the opportunity to reestablish it's correct placement. I've never had one fall off. Double glass is indeed a greater challenge. The distance of separation makes a great deal of difference. Small magnets of the above size will work, but are tenuous. Larger magnets work better. Fortunately(?), I live in an old farmhouse with single pane windows. The use of magnets on windows offers great artistic opportunities and challenges. Numerous permanent printing processes on translucent velums, mylars and waterproof papers make for exciting possibilities, especially for very inexpensive dials that can be printed from available programs and then can be taped directly to windows. Color and larger sizes are a bit more of a challenge. So far, 11 x 17 is the largest I've completed. I've recently developed a program with shading and layering of colors for hours and seasons for just this window usage. I look forward to seeing what others come up with. I think it's a great opportunity to help popularize sundials.

He is correct. The simple (but additional work) solution would be to hide it inside the mount surrounding the magnet base by winding it around that base or it could be pushed up inside a hollow gnomon, if the gnomon design allowed.

It is held in place in the by soldered lead came. See: www.kjmagnetics.com/proddetail.asp?prod=DX01 Next to it is an identical brass disk with a hole in it.

lifesaving sundial
To all of you sailor dialists, I have an instrument called a Marean-Kielhorn Director. As I understand it, it was a part of every U.S. lifeboat during WWII. It says that it is an instrument for determining direction at sea. It appears to use a system of sighting the position of the sun to do this. Has anything been written about this among the Sundial community? I have an instruction booklet for it, but haven't figured out how it works since the central pivot is frozen. Perhaps there's a way to put the instructions online for others to appreciate. sasch stephens Date: Wed, 26 Aug 2009 18:40:35 +0100 From: frankev...@zooplankton.co.uk To: sund...@rrz.uni-koeln.de Subject: symbols for sunrise and sunset Greetings, fellow dialists, An ancient sea captain of my acquaintance suggests, for sunrise, an open circle with a short straight line tangental to the bottom of the circle and for sunset a similar circle with a tangental straight line at the top. Frank 55N 1W P.S. So many sundialling sailors! I'll try to reply to each. What an oddly large interest in an instrument totally useless at sea. --- https://lists.uni-koeln.de/mailman/listinfo/sundial _ Windows Live: Make it easier for your friends to see what you’re up to on Facebook. http://windowslive.com/Campaign/SocialNetworking?ocid=PID23285::T:WLMTAGL:ON:WL:en-US:SI_SB_facebook:082009--- https://lists.uni-koeln.de/mailman/listinfo/sundial
RE: Earliest Roman Dial
what leads you to assume that it is a sundial and not merely a decorative element? sasch stephens Date: Fri, 13 Mar 2009 06:17:33 -0500 From: patrick_pow...@compuserve.com Subject: Re: Earliest Roman Dial To: sund...@rrz.uni-koeln.de ...However, there is one dial for which I have attached a picture (32kb) which was found at Housteads Fort on Hadrian's Wall and which was undoubtedly not imported Hi Frank, Your dial might be the one I saw in a museum along Hadrian's Wall all those years ago - it certainly was of that form though it was then set flush in plaster in a large square wooden frame as far as I remember. I must say though that it doesn't seem to be what one would ordinarily think of as Roman. However Gibbs reports several Graeco-Roman vertical planar dials - indeed she has a section devoted to them, One (Gibbs 5022G), though apparently undated, being in the British Museum (BM Ref: 2546)and appearing very like this one. However without any attributed date it's hard to say if it is Roman. Whatever now that some parts of a water clock have been found along the Wall no doubt they must have had some dials there at that time even if none have yet been found. All very puzzling.
