Step 11: Move the Target Back to the Near Bore
Remove the target from the Far Bore and reinsert it into the Near Bore . If the readout doesn’t display
.0000 in. both vertically and horizontally, repeat Steps 9 and 10 until the readout displays .0000 in.
vertically and horizontally in the near and Far Bore .
Note: If using the Remote Buck-In formula, when you move the target back to the Near Bore, the V and H values
should be equal to the V and H Laser Set Points. This means the laser is bucked in. If not, then repeat Steps 7-9.
Step 12: Check the Remaining Bores for Alignment to the Reference Bores
The remaining bores can now be checked for concentricity to the reference bores by placing the target in
each of the remaining bores. The readout displays the misalignment (concentricity error) both vertically
and horizontally.
In the picture above, the misalignment of Bore 2 is being measured with the R-1307. The target is in Bore
2 and the R-1307 shows a vertical reading of -.0021 in. and a horizontal reading of .0012 in. This
indicates that Bore 2 is .0021 in. lower than the reference bore centerline because the vertical reading is
negative, and .0012 in. to the right of the reference bore because the horizontal reading is positive.
