Hi Rod,
A determined vandal will move anything or destroy it in the
process. Sundials seem to present a special challenge to them. I have made
many dials which others said were likely to be stolen and so far there have
been no such reports.
My method is simple viz. the gnomon must stand on a 'foot' surrounding it then
it passes right through a 'mortise' in the dial plate into a deep bed of
mortar. The tenon is profiled to give maximum grip in the mortar bedding and
metal screws passing through the tip give an extra hold. "Steal that if you
can!" The gnomon 'foot' in my dials is usually made by machining away/thinning
some of the protruding tenon. A cast metal gnomon could provide a very
substantial foot.
For larger dial plates, bolts with large heads are threaded into the underside
of the plate and secured similarly into holes in the pedestal.
Lots of photographs on request.

P.S. I sldo recall designing a 'sundial thief trap' which had to be 'emptied
at least once a year!' ;-)

Subj: Mounting Sundials...securely
Hi all,
In the Ranelagh Estate at Mount Eliza Victoria 3930 Australia. There is a
memorial to John Thomas Smith in Ranelagh drive. The memorial was surmounted by
a sundial. It was there as late as 2004. It was removed by unknown people
several times and was replaced by the shire. But the shire eventually gave up
as the sundial could not be adequately secured.
Question, does anyone know of a way to adequately secure a sundial on the
following memorial?

It is such a shame that we all can't enjoy a sundial. Without someone thinking
that they should have it for themselves only.
Thanks,
Roderick Wall.
