Dear Hannes,
Your problem is turning into a bed of nails...
...the dial I had in mind would be vertical
and facing south-east...
That makes the problem more interesting!
... I can see no way, with my limited abilities,
to get the angles of all those gnomons right.
Any ideas?
I imagine
Good morning,
the only time I need to drill holes at an angle was through wood.
That can be done with a common drill press (ie still having the drill point
vertically downwards), however you angle upwards the material to drill into
at the appropriate angle. Also it has to be secured properly
When I need to drill holes at an odd angle (into stone or an immovable object)
I have made a drill guide in hard wood or composite such as worktop laminate. I
clamp the laminate firrmly at the required angle on my drill press and drill a
hole in it. To start a hole at a shallow angle, you can

Hi,
another solution is to make a block-dial.
The dial may have any orientation and all the pins are orthogonal to the
dial.
I'm not sure of the aestethic result, but the problem is solved from the
data.
It will be an interesting sundial?
Usually the people interested to a sundial want to be

Dear sundial friends,
during the past weeks and months you often had to read bad news coming
from JAPAN.
It is a pleasure for me to bring good news from JAPAN to you today!
A new sundial has been built on one of the upper floors of the
completely restored giant OSAKA STATION!
Have a look
I will ask in Osaka and will tell you.
In the moment many Japanese who will have to work tomorrow are sleeping
already!

Fabio, these are really wonderful ideas. I would not have
understood your block dial idea if I had not learned about
shadowplane dials fom Mac Oglesby and, I believe, Fer de Vries.

If you are drilling wood or plastic, this spade bit might
also work as the sharp point will help in starting your hole

Keeping the stainless steel as a requirement, you might epoxy a small,
high-tech ceramic magnet to the top of each SS pin.
Then, a magnet used as a probe could extract the pins, once you've lifted
the sculpture enough to take off the side load on the pins.

I haven't finished my morning coffee yet, so may be missing something, but
what sort of compound angle will this jig not do?
If you need to drill a hole off normal to the surface, the jig aligns that.
Then, if the plane of the hole is also not parallel to one of the dial plate
edges, you rotate
Dear Hannes,
You said in your first email that your reason for wanting multiple gnomons
was to avoid vandalism.
I can't see why a vandal would find a multiple gnomon dial less inviting
than a single gnomon dial. But let's assume you are right.
You also said that this would be a wall dial.
John and all,
I actually do think a number of small, boring sticks don't look half as inviting
to our average testosterone loaded kid as a prominent, well-shaped big one. But
I also admit that the idea of producing something unusual also appeals to me.
The dial I have in mind will be placed
Hi Hannes:
Tall free-standing dials are great things.
Here's a new one by Gino * Judith Schiavone that is particularly nice. It's
face is etched glass and time can be read from both sides. Something like
this would be useful next to a road. It is high enough to avoid most
vandals.
Hi all,
Some time ago someone posted a link to a webpage (was it the website owner?)
that used Google Earth to measure the declination of a wall. And to generate
a paper vertical sundial that can be pasted onto your window (inside or
outside). Maybe this could be used to calculate the
