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 telpe ( F/D = 4) well suited for deep sky observations. On the opposite, a shallow mirror ( F/D = 8) will be performing very well on planets and the moon.

Good grinding technique will produce a spherical shape, therefore the only important property needing measurement is the depth of the concave surface at the center of the mirror. The easiest way to do this is by placing a stiff metallic straight edge across the mirror face center spanning edge to edge.
