ROTALIGN 01.2000
Advanced diagnosis & correction of soft foot
Example 2
Identical and opposing ROTALIGN readings prompt feeler gauge
examination of feet B and D. Feeler gauges indicate equal rock from
one foot to another. Feet B and D are equally out of plane with feet A
and C. The inside feeler gauge readings were left out of this example
because they are often impossible to take in the field.
Conclusion: Shim both feet B and D about 50-60% of the feeler gauge
amount and recheck all four feet.
Example 3
Identical ROTALIGN readings to example 2. Feeler gauge are used to
examine feet B and D. Feeler gauges indicate equal rock, but definite
slope from foot C to foot A. This suggests that foot C is out of plane
relative to feet A, B and D.
Conclusion: remove 80/100 mm from foot C (or add 80/100 mm to
feet A, B and D). Then recheck all four feet.
