Re: Brass or Bronze for Sundials.
Thanks all for your response. Is there a particular grade of bronze that is suitable for sundials. And why are they suitable. I like the idea of stainless steel but think that bronze or brass is more suitable. Thanks in advance, Regards, Roderick Wall. - Reply message - From: "tonylindi...@talktalk.net" To: , Subject: Brass or Bronze for Sundials. Date: Mon, Jun 5, 2017 7:34 PM Hi Rod, The advantages for me is that they look good and take a handsome patination if regularly cleaned and waxed with a conservators' product. (Details on request). Corrosion is a main problem, perhaps summed up by "I am a sundial...ordinary words Cannot convey my thoughts on birds!" Hilaire Belloc .. and their corrosive droppings. :-( I sometimes suspect that my local feathered friends feed on acidic epoxy glue! ;-) Stainless steel (S316 grade) makes an excellent weatherproof dial if the surface is lightly textured to reveal a shadow and if you can find an etcher/engraver who will 'cut' it deeply enough. My preferred surface treatment was a Random Orbital sander with a worn medium paper which MUST be in contact before switching ON then lifted away before switching OFF to avoid start/stop 'swirls'. This tool is widely used on car body finishing. Tony M. P.S. Now that I know that others can view my messages I have no need to read them myself.

sunflower
Hi all I just finished to design an horizontal sundial adjustable for a range of latitude, in this case from 30° N to 50° N, I also built it with laser cut plywood. Revolving the sunflower changes the angle of the polar style, the latitude is engraved (always by laser) at the base of the sunflower, a green arrow on the horizontal dial point out to it. ciao Fabio --- New Outlook Express and Windows Live Mail replacement - get it here: http://www.oeclassic.com/ --- https://lists.uni-koeln.de/mailman/listinfo/sundial
