To deepen the mirror ( hogging out ) fastest way:
the mirror of the center can go with safety until 1 or 2 centimeters edge
of the tool and the straight runs being managed along chords may have
ten centimeters with glasses of 20 centimeters diameter; a little bit of experience
indicate the non-hazardous limit for tilting the mirror on the edge of the tool.
One can be five to ten straight races on site, then one rotates a fraction of
turn the mirror in the hands and it resumes work in a direction slightly
different, move around the post.
If the post(stand) allows full rotation of the operator, the tool can remain stationary;
otherwise it is necessary to turn the timely manner a user also all its periphery.
We see in Figure 18A, the figure described by the mirror of the center during this work
