I'm no sundial expert, but I've been reading into the field. Your explanation was very clear, and one of the few I've seen that does not leave me thinking, "yeah, but ..." after watching! The only thing I don't get is why, if you're making it for a specific location, you do not include the longitude correction on the dial face -- so in this example you would not need to subtract the 13 minutes. Very clean design and well built. Cool.
DUBBLE FASSINATING - Thank you for your clear and concise explanation - I'm now challenged to make one for UK
Very complete and precise explanation. Thank you.

You can do this. Good observation.
Thought likewise. Otherwise, make it more flexible.
Thankyou for the wonderful explanation sir
muy interesante, estaba buscando información sobre esto, gracias
Wouldn't this calibration for the compass be off after a few years due to magnetic pole shift speeding up the last few decades?
Mr. Dignard, are you still offering these dyptich sundials?
