Strokes “W”

La pass with races “W”  It is the main technique used in the process of parabolizzazione. Normally it runs with mirror above and below the tool, It can also be applied in some cases with inverted positions. The position of the hands is the one with the palm which rests and pushes from the edge to "hours 8:20"And your thumbs facing the center to

Acclimatization of the optics of a telescope, influence on observation and possible fixes.

Anyone using a terrestrial or astronomical telescope uses it to enlarge, ie virtually bring an object that is at a great distance, to observe it in minute detail as possible to their own observation instrument. A telescope is capable of receiving the parallel light rays that originate from the object under observation is, to form a

Analysis of strokes 1/3D c.o. c. (Everything you need to know who does not stop at the "come and go" of the glasses)

Past 1 / 3D c.o.c, alias the forward-backward centered race (or, all’americana: “center over center”), processing for abrasion, amplitude equal to one third of the mirror diameter, in which scratching of the glass is used to make a mirror (for example parabolic) is, with patience, UNIVERSAL WINNING WEAPON. Like the: The acquired new life

Stroke 1/3 COC

DESCRIPTION La pass with racing 1/3 center over center ( shortened: COC = “C. o. c.” ) is the classical stroke, the most widely used because it can be applied in all stages of processing both with the mirror above and below the tool, than vice versa. The position of the hands is the one with the palm that supports and pushes

Chordal Stroke

DESCRIPTION The past is the chordal excavation technique more aggressive and effective towards our mirror. In fact it allows to remove a large amount of material in a shorter time compared to the other past. On the other hand is a technique that does not allow to obtain a regular shape, It should therefore be used only in the initial stages of blanking and up
