PIN-ALIGNMENT GAUGE

Base-pin positions and lug positions shall be held to toLerances such that entire length of pins and lugs will without undue force pass into and disengage from fLat­ plate gauge having thickness of a.25 ft and tweLve holes of 0.0350" ± 0.0005" diameter located on four concentric

circles as follows: Three holes located on 0.2800" ± 0.0005". three holes located on 0.2100" ± O.OOOS",three holes located on 0.1400" ± 0.0005", three holes located on 0.0700" ± 0.0005" diameter circles at specified an~les with a tolerance of ± 0.08 0 for each angle. In additIon, gauge provides for two curved slots with chordal lengths of 0.2270" ± 0.0005" and 0.1450" ± 0.0005" located on 0.4200" ± 0.0005" diameter circle concentric with pin circles at 1800 ± 0.080 and having a width of 0.0230"

t0.0005".
