This appeared back in mid-90's in the British Sundial Society journal - probably it's the same article which F.Maes referred to by J.Moir.

The hours can be marked in ink at equal intervals while it's flat. This isn't my own idea but I can't remember whose it was - so I offer apologies and credit wherever it is due.
