Starrett Inspection Holder and Dial Indicators

This is the most versatile dial indicator holder
with an extremely stable base (A) that is
8-1/2" (215mm) long x 2-1/4" (57mm) wide
at the bottom . It can inspect workpieces on
the top surface of the ground base or within
a working area defined by the 8" (200mm)
upright base post (B) and the 9-1/2" (238mm)
long gage-holding rod (C) . The base post can
be conveniently located anywhere along the
8-1/2" (215mm) T-slot in the base .
This tool can be held in a vise or by a bolt in
a machine T-slot coming up through one of
the two 3/8" (9 .5mm) holes in the base and
fastening down on the top surface .
D . Swivel Post Snug 665D
Snug has a .375" (9 .5mm) hole for the gage
holding rod and a .465" (11 .8mm) hole for
the upright post . Also comes with the 665L
Reducing Bushing (J) that can reduce the
.465" (11 .8mm) hole to 3/8" (9 .5mm) .
E . Base Reference Guide 665E (Optional)
Guide is used to check parts or surfaces from
straight or angular surfaces by use of the
radiused guide stop . This fits into the T-slot in
the bottom of the base and is fastened at right
angles to the length . Push up to or slide along
a radius surface .
F . Square Keyway Guide 665F (Optional)
This guide can also be referenced from a
square edge, a T-slot or a keyway with at least
a 1/2" (12 .7mm) width . Has square edges and
is fastened at right angles to the length . Push
up to or slide along a square edge .

Three very useful inspection combinations can
be made by removing the complete swivel
post snug and gage holding rod as follows:
G . Clamp 665G
Take the clamp and put the clamp post into
the snug and lock it . Now this combination
can be used to clamp the gage holding rod
and the indicator into hard-to-reach places
for inspecting jigs, fixtures, lining up work on
centers and machine tables .
The clamp has a 3" (75mm) capacity and a
post with an approximately 5-3/4" (145mm)
length . The clamp post is .464" (11 .8mm)
diameter that fits into the regular swivel post
snug 665D .
Three other clamp post diameter options
available – 665G-3/8 is a 3/8" (9 .5mm)
diameter clamp post that can be used in
the regular swivel post snug 665D with the
addition of the 665L reducing bushing . The
665G-5/16 (7 .9mm) and 665G-1/4 (6 .3mm)
can be used with other snugs to hold an
indicator .
H . Tool Post Holder 665H
Put one end of the offset arm into the swivel
post snug 665D (with the 665L reducing
bushing in it) . Then put this rectangular tool
post holder 665H onto the other arm . This
combination now allows for a good, tight
setup in lathe tool posts and other machine
setups .
I . Offset Arm 665G-1
Another very popular measuring combination
is to put the reducing bushing (which is
furnished) into the snug and then put one
leg of the offset arm into it . Now the tool can
be used in a 3/8" (9 .5mm) chuck or collet to
sweep a large area .
