TYPES AND USES
The machinist's scriber is used to mark or score on
steel, glass, aluminum, copper or similar surfaces.
There are two basic types of machinist's scribers, single
point pocket (1), and bent point-straight point (2).
Tungsten carbide tips have extremely hard points and
are used on hardened steel or glass.
The bent point is used to scribe through holes or other
hard to reach places.
USING A MACHINIST'S SCRIBER
The following procedure for scribing
an alignment mark on a telescope is
not the only use of a scriber.
Place material to be marked on a firm surface.
Place a steel rule or straight edge (1) on the work beside
the line to be scribed.
Use finger tips of one hand to hold the straight
edge securely. Hold the scriber in your hand as you
would a pencil.
