Stellafane 2008 - Al-Paslow
This simple setup allows one to grind and polish a precision telescope mirror. The "mirror blank" rests atop another "blank" similar in diameter . A process of rubbing the "blanks" together with grit between them creates the curve and ultimately a precision telescope optic. The board is stabilized by anyone who sits down comfortably in the chair to begin the grinding process.
