Nice looking rake Ian.

It appears to be per the Althaus drawing?

Thanks Wayne,Jim

I am already aware of Johnson articles and Althaus's improved
version.
Neither article actually discusses any of the maths behind the design
and positioning of a rake. I'm looking for a little more detail. I
have
a prototype rake I built and I'll be testing its operation this
weekend.
