Mirror grinding Telescope making

There are many reasons for grinding your own mirror. Either you want a unusual size, or focal length, or to satisfy your curiosity, or to have the "pride of achievement" by fabricating something as precise as a telescope mirror. You could also live in a part of the world where telescope optics are not commonly available, and this might be the only way to have a telescope.
