Hello sundiallers ! What a pleasure, reading again good news under the sun ! I do work like Mike Shaw, even when I'm not in a hurry ! On my first times in sundialling, ten years ago, I realised an accurate horizontal sundial, and according with a radiopiloted watch, two levels and a rotating protractor (USA made ! : PRO-RULER safe-T LaGrange IL 60525-0692, what does it mean ? An address ?), I can find directly the declination of a wall within 1 degree accuracy. We are working on Vosges pink-yellow-white veined sandstone and such accuracy is enough.
Friendly yours Alain R MORY 7°E 48°N (GPS reading)
