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.

Subj: Brass or Bronze for Sundials.
Hi all,
For a sundial that will be out in the weather. What is the
advantage/disadvantage of using brass or bronze?
Regards,
Roderick Wall.
