Section E. Seam Measurement
Figure 34 Seam Micrometer 0 – 1“, Example #2
Example #3
Notice in this example (Figure 35) the “0” is not Mated with the Thimble Sleeve (page 51) the “2” on the Thimble is in line
with the Thimble Sleeve. We know from the previous example (Figure 34) that when the Thimble was at “0” the total was
0.250” as it is here, but … The “2” (.002) is in line with the Thimble Sleeve so we need to add that to the 0.250” (0.250” +
0.002”) = 0.252”. If the “24” on the Thimble was in Line with the Thimble Sleeve we would take the read of above 0.250”
and add the in line “24” (0.024”) = 0.274” overall.
