Roderick Wall,
I have the address you are looking for…
http://sundial.damia.net/
and I have created one of my sundials with it:

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

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

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.

Something I'm planning to do but haven't yet done, to secure a sculpture to
its plinth, is to drill two or more holes at different angles

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.

Dear Hans,
Yes, Roderick Wall is right...
... it would work if all your sticks
are parallel to the axis of the
earth.
You just need a whole set of polar-oriented
gnomons, BUT...
You have added an extra constraint...
I would like the little gnomons to be
perpendicular to the face of the
You simply arrange for the face of the dial
to be parallel to the plane of the Equator.
... and you will need gnomons on both the upper and lower sides of the dial
face if you want it to work all year.

This is a marvelous composition. It reminds me of the work of the
sculptor Roger Perry.
As far as I know he only did the one shown here:

However there must be many other opportunities such as covering a wall

I would like to thank Roderick for the solution, and Frank for pulling my leg. I
appreciate that ...
While taking a walk this morning I thought that it would work with an equatorial
dial, but I did not get far enough to realize that equatorial gnomons would do
the trick.
But the dial I had
Dear Dialists,
I am thinking about a sundial, which, to discourage vandalism, should not have a
big gnomon, but rather a number of small ones.
I thought would be neat if they could be arranged in lines, so that at a certain
