Laser Alignment

Imagine if you will, a motor with four feet, sitting on a foundation.  Unbolt all four feet and one or more of the feet doesn't sit true to the foundation.  Merely bolting the motor down and torquing the feet in place is really an injustice to a proper alignment.  While I was eating my spouse set her glasses on the table in front of me.  I saw a perfect example of how to illustrate soft foot.  The glasses did not sit on the table with all four connection points.  As it is with a motor with a soft foot condition.  A proper laser alignment will correct for this and really increase Mean Time Between Failures, bearing life and reduce electrical costs for running a motor out of alignment.  One colleague did an alignment for a company that spent the money to have the feet of the motor milled to the foundation.  First the foundation was mill then the feet of the motor.  That had to be quite expensive.  The technician thought he was seeing things when he attempted the laser alignment.  There was zero soft foot and no vertical corrections necessary to complete the alignment.
