Hi Steve:
Your interpretation of the various dial classifications seems to be correct,
although I'm certainly not an expert, as you know! Reading your letter,
which was written so clearly, gave me confidence that I had interpreted the
discussion correctly.
Thanks,
John C.

I can see that in abstract terms that we have dials which are
- projection of a point onto a surface (perhaps curved)
- projection of a line (perhaps curved) onto a surface (perhaps curved)
- projection of two lines (perhaps curved) onto a surface (perhaps curved)
- other non-projection types,
That was a short article but an interesting concept of mapping the lines on
a transparent medium and showing time where their shadow meets a point. A page
or two later in that Compendium, Fred Sawyer showed how a stained glass window
could apply the concept. I know Claude Hartman has done
I try to answer to some of the last messages on the subject
John Carmichael has written:
And I give you think that we should stop using the term monofilar to
describe Singleton dials?
I don't know the Singleton Sundial and so I cannot answer

Ah ha! I must have misunderstood the issue being discussed.

Should the (projection) dial types by axial, linear, and bi-linear?

I should point out that my dial reads time by a
projection of a point onto a point (the first point being on a surface)
and that it reads standard time.

Oops, I knew that...

Apologies,
