WHAT KIND OF SUNDIAL TO BUILD
Before you build a sundial, decide what kind is best. Latitudes between the
equator and about 15 degrees N or S would benefit from an equatorial (q) or
polar (p) dial more than from a horizontal (h) dial design. On the equator a
horizontal (h-dial) is a polar dial so use a p-dial design. At the poles, an h-dial
is an equatorial dial, so use a q-dial design ~
run the DeltaCAD h-dial at low
and high latitudes for fun, they approach the polar dial and q-dial
.
