I am looking for information regarding the use of a trumpet for solar
concentration.  In particular I recall seeing some years back a method to
draw and construct a hyperboloid reflector for concentration using a
T-Square (no I am not thinking about the red rok parabola T-Square method)

Any assistance ?

Thanks
John

Try this:
http://www.google.com/search?q=hyperbola+t-square
Especially this:
http://astro.temple.edu/~dhill001/conic_via_locus/

Actually the hyperbola uses a strait edge and string.
