Frequently   Asked   Questions ,   on  "Sunclocks"
 
 
 
 
WHAT SIZE IS A "SUNCLOCK" ?     You must have a  LEVEL  piece of
ground, which is at least 6 metres (20 feet) in diameter.   It will be ELLIPTICAL
in shape  -  6 metres (from East-to-West),  by about 4 metres (North-to-South).
 
If your available area is slightly smaller than this, then you might still be able to
install our "Sunclock" - assuming you are more interested in using your shadow
to tell 'Daylight-Saving' time (in summer), rather than 'Standard' time (in winter).
 
 
The "Sunclock"  is not suitable for an area which is less than 4 metres (14 feet)
from East-to-West, because layouts would be 'cramped' and not very accurate.
 
Unless you request otherwise, our customized Layout Plans are produced for a
recommended size of 6 metres - but please contact us, if you need any advice.
 
 
 
 
HOW ACCURATE IS THE "SUNCLOCK" ?     Providing it is set-out by
following all the Measurements and Instructions in our customized Plans, then it
should indicate the correct 'clock' time all year round - to better than the nearest
15 minutes, since its accuracy is limited by the width of your own body shadow.
 
However, this assumes that you would be installing the "Sunclock"  layout using
our recommended diameter of 6 metres.  Accuracy will be less for smaller sizes,
but there is no point in making your layout any larger than 8 metres in diameter !
 
Also see below, for restrictions on suitable Latitudes for Human Sundial layouts.
 
 
 
 
WHAT ABOUT DIFFERENT TIME ZONES ?     Every set of "Sunclock"
Plans is uniquely calculated, for its own location in the Time Zone - including any
required 'correction factors', so that the layout will indicate correct CLOCK time.
 
Most conventional sundials show 'Local Apparent (Solar) Time', plus are usually
not adjustable to allow them to be used at different positions within Time Zones.
 
If you are located in a large country, which has several Time Zones (such as the
USA or Australia), and are intending to buy a set of "Sunclock"  Plans - we ask
you to confirm a specific Zone, when entering details into our 'Response Form'.
 
The diagram, below, is centred on the "Greenwich meridian" in Britain - showing
how many hours parts of the world are either 'fast' (positive), or 'slow' (negative).
 

 
This map, above, only gives an approximate indication of the differences - but if
you may like some additional information on Time Zones across the world, then
please click on this link to down-load a more detailed diagram (in PDF format).
 
 
 
With a large proportion of our customers being in the United States or Canada,
the following diagram shows Time Zones across the North American continent.
 
Note, however, there are a few 'anomalies' within several States - (for example,
in Indiana) - where locations might, or might not, use any Daylight-Saving time !
 

 
 
 
 
WHY ARE THERE  2  RINGS, OF 'HOUR-MARKERS' ?     This is in
order to cope with both Standard and 'Daylight-Saving' time - so that you do not
need to change your layout, when clocks go forward, or back, twice a year.   Of
course, if you are in a country which stays on the same time all year, then there
is only ONE ring of Hour-markers - but this has a different central 'Date-scale'.
 
 
On our 'double-ring' layouts, you MUST install both rings of Hour-markers, for
Standard & Daylight-Saving time.  If you set-out just one of the rings, then your
"Sunclock"  would only be accurate for half of every year - and please note that
you cannot simply 'add or subtract' an hour, to/from the time that it is showing !
 
This is because its 'Date-scale' has been calculated for TWO rings.  If you just
install one of these, then (depending on the month) you will be "standing in the
wrong place" - and so your shadow would not be pointing in the right direction,
towards numbers on a (missing) ring of Hour-markers which should be there.
 
 
Please note that we only provide 'double-ring' plans for any locations which
use Daylight-Saving time - even if customers might prefer a single-ring layout,
since we do not recommend just one ring (because a person's shadow will be
too short to reach the 'Hour-markers' in summer, and too long in winter-time) !
 
Our double-ring is much better for 'tracking' their shadow, throughout the year.
 
 
However, if you definitely want the plans for a 'single-ring' layout - then please
send an E-mail message to Jonathan Hamp (in UK) who may be able to help
you, although we would not guarantee the 'quality or accuracy' of those plans.
 
Alternatively, you can send an E-mail to Harriet James (also in UK) - and who
should be able to supply similar plans, though they might be quite expensive !
 
 
 
 
DOES A PERSON'S HEIGHT MATTER ?    Not at all - because it is the
direction of their shadow which will indicate the time, not its length.  It makes no
difference how tall or short a person is, so "Sunclocks"  are equally suitable for
use by small children as well as larger adults.   This is like having a clock with a
longer or shorter 'Hour-hand', where the actual length does not matter - you can
easily tell correct time by the direction in which it is pointing, on the clock-face.
 
Our recommended diameter of 6 metres (as above), is the best size for use by
both children plus adults.  If it is being used by a very young child, then they can
simply put their hands together, above their head - which will 'extend' the length
of their shadow, and so bringing this much nearer to the rings of Hour-markers !
 
"Sunclocks"  are certainly very 'interactive' sundials for children, plus are shown
in School-books (UK and USA) due to the curriculum-wide educational benefits.
 
Since these are essentially theft-proof, and do not interfere with grass-cutting on
any lawn area - they have also become very popular as unique garden sundials.
 

 
 
WHAT ABOUT THE 'SOUTHERN HEMISPHERE' ?     We can supply
our "Sunclock"  Plans for most countries - so if you are in (say) Argentina, then
there is no problem.   It will look like a 'mirror-image' of layouts for the Northern
Hemisphere, shown in the illustration on the introductory page of this web-site,
(since your shadow moves 'anti-clockwise' in Southern Hemisphere locations).
 
The layout would have just one ring, of Hour-markers - as there is no 'Daylight-
Saving Time' in Argentina (unlike its neighbour, Chile, which does use D.S.T.).
 
 
If you are located in Australia or New Zealand, then you can click this link to go
direct to the web-site of  Ross McGuinness - our Distributor for those countries.
Alternatively if preferred, you can just telephone Ross on: +61 (0) 8 9848 1781.
 
Ross is based in Western Australia.  If you are on the other side of the country,
then you could instead go to the web-site of George Marshall - who is based in
the Brisbane area - or just contact him by telephone, on: +61 (0) 7 412 48 196.
 
For convenience, Australian customers can order "Sunclock"  Plans direct via
the "Leaf & Stone" gardening web-site  -  although their price would be slightly
higher, due to the additional 'profit-margin', which is applied by that Company.
Alternatively, contact them by telephone, on the number: +61 (0) 3 5221 8083.
 
 
   Due to unreliability plus communication problems, with our previous
Agent, we are currently looking for a new 'Distributor' to represent South Africa.
 
   We would also like to find a 'Distributor' in Canada, to represent us.
They will be offered an 'exclusive right' to market our "Sunclock"  Layout Plans.
 
 
If you, (or any other persons you know), might be interested in this - then please
ask them to telephone Douglas Hunt, to discuss it further.  Remember that we
offer Distributorships as a 'Free Franchise', outlined on our Opportunities page.
 

 
 
However, in the 'tropics', layouts would be very different - with the Hour-marker
'rings' becoming almost straight lines which cut through the Date-scale, and so
we do NOT recommend our "Sunclock"  for any locations near to the Equator !
 
A "Sunclock"  is only suitable for locations which are in the Latitude range of
25 Degrees to 65 Degrees, in both the Northern and Southern hemispheres.
 
It is illustrated by the two 'pink bands' in this map-of-the-world diagram, below,
so regions such as southern Mexico and central/southern India are unsuitable.
 

 
 
For Australia - please note that the majority of Queensland, Northern Territory,
plus the northern third of Western Australia, are (technically) inside the tropics.
 
We suggest that you ask for our advice concerning any such 'tropical' location.
 
 
 
 
CAN YOU GIVE ADVICE ON MATERIALS ?     Most of our customers
are SCHOOLS - who simply PAINT the "Sunclock" on their playground.   Other
people use stone, wood, concrete, mosaic, etc  -   or even turn them into 'floral
clocks'.   By deciding on your own materials, you can be sure that your layout is
absolutely UNIQUE to you - although (in Britain), there are now several sources
of ready-made "Sunclock" component-parts.   However, such 'kits' can be quite
expensive - but if you need some additional information, then please contact us.
 
 
If you would like to see photographs of "Sunclock"  layouts, using a wide range
of materials  -  then please click on this link, to visit our  'PICTURE  GALLERY'.
 
Here are only three of the many images which can be found within that section.
 
                
 
These are just small copies  -  their full-size photographs (together with further
details for each of them), are contained in the 'Picture Gallery' on our web-site.
 
You may also click on each of the pictures, above, to obtain more information.
 
 
 
If you are interested in making/installing our Human Sundials (in any materials
of your choice), then please see the  Profit Opportunities  page  -  or contact
Douglas Hunt, to discuss ideas which you might have in connection with this.
 
(For example, make some money by simply painting layouts on Schoolyards).
 
 
 
 
WHAT DOES THE SET OF 'PLANS' CONTAIN ?     These "Sunclock"
Plans are uniquely calculated and printed for the location you specify, anywhere
in the world.   They are produced in A4-size thermal-bound booklet format - with
the exact (metric) measurements required, and detailed setting-out instructions.
 
All of the dimensions given, are based on a very simple 'grid' system - plus this
will automatically create its correct elliptical shape, (without complex methods).
Only a normal measuring tape is needed, to set-out your full "Sunclock"  layout.
 
We also give you a method (again unique to your location), which allows you to
find the true North/South direction - without having to use a magnetic compass.
 
Please note that all "Sunclock"  Plans are only available in ENGLISH language,
and they are printed on non-photocopiable (bright red) paper - so if you might
need to take any copies, then we would recommend our 'E-mail' (PDF) version.
 
 
Most people now request the customized sundial layouts in one of our E-mailed
formats - which are either in HTML (simply viewed in your 'Web Browser'), or as
PDF documents (gives the best quality but you will need appropriate software to
read them).  Either of the E-mail versions entitle you to claim a 5% DISCOUNT.
The HTML format is currently being 'phased-out', as few people now ask for this.
 
The content of 'E-mail' Plans is exactly the same as in our original 'Printed' style.
 
If you need to 'print-out' from our HTML version, then the 'page formatting' would
vary on different computers, or printers - but print-outs from PDF documents are
not affected.  If you may like to see a SAMPLE, then you can click on this link to
down-load one typical PDF page   ("Auckland Botanic Gardens", New Zealand).
 
To see a FULL set of 'sample' Plans, you must telephone us to ask for this - and
we shall then be glad to make that information available to you, (in PDF format).
 
 
Remember that every set of our "Sunclock"  Plans would contain detailed layout
instructions, and measurements - which will be UNIQUE TO YOUR LOCATION.
 
You only need to find a suitable area of level ground, plus select the material(s).
 
The cost of your Plans also includes help, or advice - if you have any questions.
 
 

 
 
CAN WE BUY THE PLANS BY 'CREDIT-CARD' ?     Currently, we do
not offer any Credit-Card facilities, simply because most of our customers tend
to be Schools.   However, you can either send us a cheque-with-order, or 'wire'
the payment directly to our Bank - and remember that we offer a small discount
for such payments-with-order.   If you may prefer to 'wire' payment to us, please
request our Bank details - but the 'wiring' option is only available to Educational
Authorities, purchasing for Schools.  Alternatively (in connection with a School),
then we can also accept Official Orders, against which we will issue an Invoice,
but in that case you would NOT be entitled to our payment-with-order discount !
 
 
However, if you definitely want to make a payment by Credit-Card - then we are
happy for you to do so via our main Australian distributor, although the price will
be higher than we charge (due to their own profit-margin on "Sunclock"  Plans).
 
 
                         
 
 
If you are in the United States, payments can be arranged through an American
branch of our main British installer - by clicking this link to Surface Signs (USA).
 
You could also telephone (718) 507 5437, and ask to speak with Caroline Kelly.
 
PLEASE NOTE :   If you do not get any response at all, from Caroline, within a
reasonable time - then just click on this link, to send a 'complaint' E-mail directly
to Surface Signs (UK).   In such a case, we recommend that you simply contact
our Australian distributor, instead - who will gladly take a Credit-Card payment !
 
 
Within the UK, you can send a 'Credit-Card Cheque' - which we shall accept as
payment in the usual way, but it would be charged to your Credit-Card account.
 
Note that we only accept 'Credit-Card Cheques' if issued by UK-based Banks.
 
 
If you are paying by cheque, please make it payable to "Modern Sunclocks",
and then send it to our address shown on the 'How You Can Contact Us' page.
 
 
For overseas countries, you can find out the equivalent of our price in your own
currency.   Follow this link to a  MONEY  CONVERTER , on our 'Contact' page.
 
 
 
 
HOW QUICKLY WILL WE RECEIVE THE PLANS ?     All "Sunclock"
Plans are normally produced on the same day that we receive your order - and
(in Britain), are sent by First-Class post.     For any 'overseas' orders, these are
sent by Airmail, and so they should arrive in a maximum of a week to ten days.
 
Requesting your Plans in an E-mailed format will eliminate the postal delays,
plus also ensure that they cannot become physically damaged or lost in transit.
 
Remember that requesting an E-mail version entitles you to 5% discount, too !
