Hey there,
        Here is what yo do.  1) SCREW THE MATH!!!!!!!  2)Take your desired
focal length, double it and make a beam compass that length.   3) Obtain a
piece of sheet metal, or alminum  4) Scribe an arc on it with the compass
5) cut and file to the line.  This will result in the most usefull piece of
mirror making equipment ever created.  Let me know if you do this, and how
it works.

Ciao,
Nutso Nate
