Abstract:
A gage for measuring deflection of a "mini-strip" used to
determine peening intensity in small cavities and crevices of
a work piece includes a pair of platforms made of a magnetic
material spaced apart in a non-magnetic fixture a distance
substantially the same as the length of the mini-strip. The
platforms have a diameter slightly larger than the width of the
mini -strip to provide support for both comers on each end of
the mini-strip. A magnet for each of the platforms may be
advanced toward and retracted from the platform to adjust the
degree of magnetic attraction of the mini-strip. The platforms
are stepped to define a shoulder and posts are offset from one
of the platforms which cooperate to guide the user in proper
placement of the strip. A plunger extended from the indicator
engages the strip at substantially its midpoint, to thereby
measure the deflection of the strip to give an indication of
peening intensity
