Thanks for all your advice, about my 'Human Sundial' business

2013-04-26 Thread Reena Gagneja

Dear List Members,

Many, many, thanks to all of you who responded so positively to my
recent request for advice - on setting-up a Human Sundial business.

Most of you replied directly to myself, instead of to this Mailing
List (which surprised me) - but perhaps you wanted to keep your own
ideas 'private', and not have them viewed by the other members!


All of your suggestions were helpful - and I must mention special
thanks to the following people, for their very kind assistance.

(a).  Linda Reid, who offered to produce 'kits' (using mosaic).

(b).  David Patte, who can assist with the design of my website.

(c).  Martina Addiscott, giving advice on marketing to Schools.

(d).  Dave Andersson, who could help with 'website ranking'.

(e).  Anne Lennon, suggesting contacts for layout information.


Based on all of your advice, I will initially be concentrating on
the large 'up-market' properties within outer London suburbs - as
they have big gardens, plus being owned by wealthy people who also
want to possess unique features which their neighbours do not have.

I shall be contacting Landscapers and Garden Designers so that
they will do some of the 'marketing' of this concept for me, but
I already have around twenty expressions of interest.  At 1,500
Pounds profit per sale, that could be 30,000 Pounds of (pre-tax)
income - but I suppose that I should not count my chickens!

Even at just one order per month, on average, (based on the whole
of the UK, plus allowing for a lull in Autumn/Winter), it is
18,000 Pounds basic profit in a year.  If I also charged for an
'installation service', there could be even more income - but I
would obviously have to pay people, to do that aspect for me.

Each layout should become its own advertisement, as well, plus
automatically giving me further 'word-of-mouth' referral orders.


If/when Linda Reid can produce her mosaic kits, it will provide a
more colourful alternative to the ones being made by Fosstone,
and so I may even be able to charge more than 2,500 Pounds each.

For example, some local Councils have indicated that they would
be willing to pay up to 5,000 Pounds for a complete installation.


Do any members of this List know people who could offer parts made
in 'rustic wood', as potential clients asked me for those?  They
think it may look better in their garden than a stone effect, and
I suppose kits in wood will be cheaper to make (plus transport).

That would give me a much bigger 'profit-margin' per sale, (or I
could lower the price to attract even more orders) - and Martina
Addiscott also suggested wood for environmental School Gardens.


All I can say, is that this Mailing List is amazingly useful - and
please watch this space, for any developments with my business! 


Yours sincerely,

Reena Gagneja.

Alt Augsburg revisited

2013-04-26 Thread Robert Terwilliger
I find it curious that nobody chose to respond to, or comment on, the
instruments illustrated in the book Kunstuhrmacher in Alt Augsburg 

 

I put images online at:

 

http://www.twigsdigs.com/sundials/kunstuhrmacher/kunstuhrmacher.htm

 

These instruments had to be expensive, and since there seem to be a few
surviving, somebody must have purchased and used them.

 

I have a l lot of questions.

 

 How were these instruments used?

 Were they to be used in sunlight?  If not, what was the gnomon for?

 How and why did the single hand indicate the hours from VI to VI?

  What happened at night?

Two of them have the sundial-style line and curves to indicate
declination/astrological sign.

  How did this work?

 

Is it possible that these instruments were so early that the makers gave
them the appearance of sundials to give the impression of accuracy to users
who previously knew only sundials as time keepers?  

 

The first instrument illustrated is the only horizontal one and it appears
to have been photographed from the north. It also has a dial (the left one)
divided into eight segments with engraved illustrations and Latin text I
wonder what that's about

 

Until seeing these photographs I didn't know such things existed.

 

Bob

I will start a guess.  I think the Hour hand below the gnomon was to be set
manually by the user to align with the shadow line from the gnomon.  This
hand was mechanically linked to the central clock dial minute hand, to show
minutes past the hour.  In this manner, a user would use the sundial to get
a close estimate of the exact time, told by an hour hand and a minute hand.
 There exist other less complicated examples of German dials using a minute
hand mechanically linked to some kind of moveable shadow indicator.

The other clock dials seem to show day-of-week and day of month, and maybe
a lunar calendar as well.  Maybe there is an equation of time mechanism as
part of the calendar, but I can not tell.  How these would function, I have
no idea, but I can't imagine that they were mechanically linked to the
sundial.

These astronomical clocks are part of a tradition of elaborate and complex 
clocks that showed all sorts of astronomical information.  They are largely 
found in courtly collections put together in the 16th and 17th centuries.  The 
inclusion of sundials on them was common in order to set the time of the clock.

A fine collection of clocks by Jost Burgi and others is found in Kassel:

Both cities were very heavily bombed during the war, so we are very
lucky that these have survived.
