  Carlos Paris visitor from Ft. Myers
Carlos Paris was a visitor from the Ft. Myers area and needed help with his 6" mirror. He has
been working alone on it using an impessive home-made Foucault tester and a couple of good books.
Now he was ready to start figuring it. He finished it at the lab better than 1/9th wave during
his first visit (also 6/2).

  Steve Fredlund
Steve Fredlund started his mirror at the lab and finished it better than 1/7th wave last Saturday
