Cut a hole in the turf, slightly deeper than the paving stone so the grass will grow over it
Fine dry sand is spread
and levelled
A sling is fitted to the paving stone
so that it can be carefully placed
on the levelled sand without disturbing it
It is surprising how many times a little more sand has to be added to one side
Meanwhile, the top of the plinth is marked out with the slot to receive the base of the gnomon
and the soft sandstone slot is chiselled out
Returning to the levelled paving stone
the sundial is fixed to the top of the plinth, which is placed directly on the paving stone, and the level is again checked
At the exact time of solar noon, the sundial and top of the plinth are rotated till the line of light appears
and a pencil line is drawn on the paving stone - this is the true medidian (north-south) line
The bottom section of the plinth is then placed on the paving stone, lined up accurately with the pencil line, and cemented into position.
Then the middle section of the pointh is placed in position and cemented in
and finally the top section similarly
and then the sundial is permanently fixed
and looks as if it has always been there
