The Skywheel








16,765

The Skywheel is an innovative sundial in the form of a wheel with 24 spokes, one for each hour of the day. And, precisely on each hour, the shadow of the central rod falls exactly along one of the spokes.

Each Skywheel is individually made for its exact location. There is ample space for extensive personal engraving, including images or logos if required, on the mirror-polished baseplate. Delivery of the Skywheel is normally around 6 weeks from the time the engraving is finalised.

These pictures illustrate the standard 48 cm. skywheel which is supplied with a 42 cm. square mirror-polished baseplate which can be engraved to your specific requirements.

These views show how the Skywheel glints

in the sunshine almost whatever the angle






The mirror polished baseplate gives stunning reflections of the sky and clouds, the underside of the wheel and neighbouring trees and buildings

In winter, the sun shines on the underside of the wheel but you can still tell the time, as shown below

The Skywheel makes a focal point for the garden

From the back, you get this marvellous visual image from the reflection of the Skywheel in the baseplate
When sun time is exactly on the hour, the shadow of the gnomon (the rod that casts the shadow) falls exactly over one of the spokes of the wheel (see top left). The vertical spoke is twelve noon by the sun (around one o'clock in British Summer Time), and in this picture it is exactly 5 o'clock by the sun.
Between each of the spokes, there are 5 nicks in the circumference of the wheel. When the shadow of the gnomon is exactly astride one of the nicks, it is successively 10, 20, 30 ,40 and 50 minutes past the hour. So in this picture, it is 20 minutes to 5
Telling the time .
Please note that these pictures show the first production model before the hour markers are engraved on the surface of the wheel at the point where the spokes meet the circumference. We will post pictures with these hour markers shortly

In winter, the sun shines on the underside of the wheel, but it is still very easy to read the time. When the shadow of the gnomon is exactly along one of the spokes, it is exactly on the hour (see left hand picture below)

Here, the shadow is nearly exactly between the nicks which means it is 15 minutes past he hour.

These three pictures show the hour markers on the outer ring of the Skywheel
