Mirror grinding - scope 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.

Study on a 5-axis precision and mirror grinding of glass ...

The precision freeform grinding depends on the on-machine truing of diamond wheel, leading to the inefficiency of grinding system. Hence, a virtual ball-end algorithm along with a fixed tool posture angle is proposed for the 5-axis grinding of glass by using a self-dressing diamond wheel. The objective is to realize the precision and mirror freeform grinding without any wheel-profile truing ...

Build your own telescope part 1: The mirror – Thomas ...

Rough grinding. This step is about making one side of the glass concave. It will give your mirror its overall focal ratio. If you make the centre deep, you will end up with a fast telescope (e.g. F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon. The theory behind grinding is that you can remove ...
