I picked up a Co-Ax off ebuy a few years ago, and I'm getting my
money's worth out of it. Bought the 3" inside feeler, and was stumped on
why it wouldn't pick up on a 1.375 bore...

Manly-man adventures deleted. The secret to adjusting the swept diameter
is to pivot the feeler outward. The phillips screw just above the feeler
socket is the pivot for the feeler assembly. You can loosen it up or
tighten it with the phillips screw / acorn nut. Duh.


To answer the question of what the Co-Ax measures, the dial says
(Quote).0005" AXIS

Does that " stand for inches or minutes?


If I understand your question correctly, I believe it means the spindle
holding the indicator is .0005" inches "off center line" with the bore you
are sweeping.

I have been using a Blake for many, many years and love it. But I never
cared about the graduations, I just center it as close as I possible can and
go for it.

I loved mine, I could center holes, pins, etc, in short minutes -
faster than I could any other method, even including the 'set up'
time.
