André,
Maybe one of these?
New Method Of Setting Sundials – An Improvement / Rolf Wieland / The
Compendium 21(1), March 2014, pp.12-14
Introduction: In The Compendium 20(4) from December 2013 we could read
on page 4 the following intriguing method of setting a sundial described
in the Time's Telescope for 1824 (Nov. 1824, p. 283): On a bright day,
set a watch exactly with the dial at 9 o'clock in the morning, and at 3
in the afternoon observe the difference between them, and correct the
dial to half this difference. Proceed in the same manner till the watch
and dial are found to agree perfectly. This is a surprising and easy
method and in the beginning I could not believe it would work...
An Easy Method To Find Proper Alignment / Bill Gottesman / The
Compendium 9(2), June 2002, pp.7-16
Does your sundial read properly all day long, or does its accuracy drift
during the day? Would you like to have an easy method to determine how
to adjust your dial’s position to accurately read solar, standard or
daylight savings time? This article describes a new method for taking
three time measurements from your dial, and then using that information
to calculate how to tilt your dial to obtain accurate alignment with the
North Pole and the time meridian of your choosing....
Cheers,
Steve

Looking for the 3 pages article published in BSS or NASS 10 years?
about rectifying a misaligned pole-style horizontal or vertical sundial.
