29B
Starrett Scratch Gage

This tool is extremely useful for scribing
lines parallel to a given surface. It is made of
steel and the head is hardened. The gage is
securely locked by a knurled clamp screw and
split bushing in the head.
The marker is a square piece of thin tempered-
steel firmly held against the edge of the beam
by a screw. The beam is graduated a full 6" by
64ths of an inch, and fine adjustments may be
made by a slight rotating movement of the head.
