    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.

    With the Mirror on top the tool on the bottom and coarse grit in between we start grinding with the mirror overhanging the tool. We rub the center of mirror against the edge of the tool and this wears a depression in the center of the mirror (the edge of the tool wears down also so that the tool becomes convex (a "hill" in the center) and the mirror becomes concave (a shallow "bowl").

     · During the grinding process only the depth of the concave surface is measured. 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. You then measure the gap between the straight edge and the mirror face at the center with a set of feeler gauges. You can also use a "spherometer" which isa device that can measure the radius of curvature (ROC) of the concave surface. You must measure often when "hogging" out the center of the blank. A very common mistake is to overshoot on the concave depth. If you do this it will take at least five times as long to recover that depth as it took to dig the hole in the middle of the mirror.
