I hope it's ok to slip this into the conversation about vertical dials. Last year I finished building a medium sized CNC router table, it has a carving area of 3'X 4'. I made it especially for making vertical sundials. Even though it looks like something that Fred Flintstone built ,It will cut aluminum and brass but only reluctantly; I'm using a 3 ? horse wood router that really doesn't have the bearings to push through metal for very long. I have experimented with different materials and like a material (PVC) that is made for exterior trim ( it looks like painted wood) and comes in boards and sheets up to 4'X 10', I have made several dials from Pine and then painted them. I use the Sonne program to generate the Analemma and hour lines in dxf form and old versions of AutoCAD and Corel to add framing and text. I am offering this information for two reasons . The latest thread about vertical dial and dials on cupolas reminded me that there might be members that were interested in using me as a resource in construction low cost vertical dials. Secondly, I was invited to do a write-up or presentation to the compendium on building low cost cnc machines for dialing. I am willing to share what I know. But the task of putting together a formal authoritative presentation about something I really don't know much about is out of the question. What I have considered is a collaboration with some one or a group from the dialing list that is interested in building their own and writing about it. There's is a picture of the machine and some of my dials on my web site. Spend a little time on the site and you'll understand why I don't want to write the presentation. I don't write! www.scottdesignsundials.com there is a link to a Sign site with lots of signs carved in oak which is turning out to be my bread and butter.

I believe the owner originally intended to put a clock in as well but am not sure whether he ever did. I can think of a few other similar arrangements around the country - for example I think Goodwood House has a large 18th century sundial and clock in such a position. However I can't recall seeing a proper set of four dials so arranged. Do you count the Gate of Honour at Gonville and Caius College, Cambridge, with its six sundials, as a cupola? See http://www.cai.cam.ac.uk/map/cCourt.php for a good view. If you ground the weathervane, bear in mind that lightning conductors should be substantial, avoid sharp bends, and go to a very good earth indeed.

I'd like to put a sundial on each face of the cupola and then a neat weathervane on top. <snip> Have any of you ever seen a cupola or "clock tower" with sundials instead of clocks? John p.s. Do you think the copper weathervane will act like a lightning rod? Maybe it should be grounded? <snip> PRI Limited, PRI House, Moorside Road Winchester, Hampshire SO23 7RX United Kingdom Tel: +44 (0) 1962 840048 Fax: +44 (0) 1962 841046 www.pri.co.uk The Intelligent Metering Company This correspondence is confidential and is solely for the intended recipient(s).
