Preferentially grind the mirror back where the wedge is too thick. Then re-grind the mirror back flat. Measure again and repeat until the wedge has disappeared. Wedge can cause astigmatism; the thinner side of the blank flexes more and adopts a different radius of curvature.

Grinding and polishing the mirror is the most difficult part of making a telescope. And the most critical. Mirror-making is a hobby that has been around for many years, and many people have put their hands to the task, but it is time consuming, requiring a great deal of skill, patience and perseverence. Especially when the mirror gets big.

Mar 06, 2006 The larger one is for grinding and polishing mirrors and is also used at higher speeds to centrifugally cast resin mirrors, an experiment I am playing with in my spare (sic!) time. The smaller mirror is used for power wrapping epoxy impregnated fiberglass around mandrels for making tubes and cylindrical components for open trusses.

Typically, the primary mirror is made of glass. Pyrex is commonly used for the primary mirror because of its thermal stability, but for small mirrors, plate glass will work fine too. Telescope mirrors are relatively thick. The concave shaped face is made by repeatedly rubbing the primary glass blank over another blank called the “tool”.

May 30, 2014 This is how you make a telescope mirror out of a hunk of glass: Use a sand mixture and another piece of glass to grind away the middle of a concave shape. Repeat with finer and finer grit sand. Dave Barosso demonstrates the technique, but to do it yourself, try to visit one of the Telescope Makers Workshop ‘s classes on Friday nights in Oakland.

Placing the mirror face up and grinding with a moderate "W" stroke will also move the curve toward the edge, and tends to produce a more spherical surface. Leaving the mirror grossly hyperbolic will make fine grinding difficult. Fine Grinding . We've all heard stories about fine grinding taking hundreds of hours.
