Michael,
Yes, I recognize that to get Mean Time involves Equation of Time
adjustment and that Equation of Longitude can be handled there to give
Standard Time (or DST).
But anyway, my inquiry was to seek an online wedge calculator. Nobody
identified one and a week seemed an adequate wait for responses, so
I've just written one. Anyone who's interested, please see
https://sundials.org/index.php/teachers-corner/sundial-construction/367-easy-dial-adjustment-for-your-latitude
Cheers,
Steve

I just want to mention that the shim under the north or south edge of
the dial is only for latitude. Longitude is corrected-for by changing
the constant term of the Sundial-Time to Clock-Time conversion.
But usually Sundial-Time, Local True Solar Time, is what I’d want from
a sundial.

Hi,
Can anyone point me to an existing online calculator for making a
wedge
to adjust a horizontal dial to a new latitude and longitude?
I am not asking for an explanation of how to do the calculation; I
just
want to be able to point people to a calculator that has already been
proved on the internet. It should use the original location (latitude
and longitude) and the new location to calculate the angle of
slope of
the wedge and the required rotation from the meridian.
Many thanks,
Steve
