I enjoy these descriptive diagrams.
Very useful at times.

Very interesting. It reminded me of how geometers show that a
semicircle is full of right triangles--one
formed from each of the endpoints of of the semicircle and any other
point on the arc. This is rather like
a reverse version of that.

I have been looking for an article that I saw recently. I have not been
able to find it. It described, in more detail, the method that is being used
in Fig 5-41. I think that it would work well in this situation.

Fig 5-41 gets the job done; however, it is physically more difficult
to get an accurate camber than to use some basic drafting tools to
do a simple lofting layout.

This is especially true for spans longer than 3'-4'.

Of course I'm biased having spent a few years on a drafting
board while putting myself thru engineering school as well as
building the profiles for the deck cambers of a sailboat I built.

You might enjoy Bingham's book, "Practical Yacht Joinery".

A book of very useful techniques on a small budget.

Bingham has chapters like "Happiness is a $5 Table Saw"
as well as jigs and fixtures that I have found very useful.

Should still be available at Amazon in paperback, mine was $20,
a few years ago.

Also could try local library.
