Re: Brass or Bronze for Sundials.

[rodwall1...@gmail.com]

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.

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.

P.S.  Now that I know that others can view my messages I have no need to read 
them myself.

Hi all,
For a sundial that will be out in the weather. What is the 
advantage/disadvantage of using brass or bronze?

sunflower

[fabio.sav...@nonvedolora.it]

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
