· edging machine that can grind the outer diameter and put bevels on both sides in one run. Although less common, bevels can also be added after centration, either using a stone grinding wheel or convex or concave bevel tools.
(3) A homemade telescope mirror can be made with more accuracy and smoothness than the massproduced, commercial mirrors available today. Unfortunately, the cost of mirror grinding kits and pyrex blanks has increased significantly in recent years to the point where any savings from making a mirror versus buying one are minimal at best.

Telescope Mirror Blanks Providing telescope mirror blanks and kits to telescope makers. Mirror blanks are individually tested for internal strain. Plastic protractor inserted under a 6 inch mirror blank during a stress test, to illustrate what stress would look like if there were any present.
Folding Mirrors. The Webb Telescope team also decided to build the mirror in segments on a structure which folds up, like the leaves of a dropleaf table, so that it can fit into a mirror would then unfold after launch. Each of the 18 hexagonalshaped mirror segments is meters ( feet) in diameter, flat to flat.

NB. We do not provide details of mirror grinding and figuring as this is amply covered in several specialist books on the subject. However we do include, with our mirror kits, information detailing the sequence that should be followed from 80grit, through to Cerium Oxide polishing. Grinding Powders Etc
In theory, the process requires a minimum of three parts. The actual number is determined by part quantity, part size, and machine size. With doublesided lapping and polishing (DSLP), the optical components are held in geared or sprocketed carriers that are driven in a planetary motion covering the full surface of the lapping plates and are subject to continually changing direction of rotation.
