This is a type of Reverse Dial alignment that could prove quite useful when one unit that can be manually rotated is being aligned to another unit which is either impractical or impossible to turn. Or, what if you re assigned to align a bare shaft unit to a stationary unit that can be turned, but is not to be moved? Pursuant to these thoughts/comments, in this chapter it s mandatory that movable and static units be clearly labeled and appropriate formulas written for said scenarios. (My obligation). Further, once these precautions are made along with the correct formulas attached, these formulas have to be followed exactly or they simply will not work. (Your obligation).

True enough, this isn t a format you ll be called on to use very often. Yet, the theory is sound, the indicator format is physically practical as any other, and mathematics don t lie. Besides, with this format, SOMEBODY is going to save a lot of $$$ in the Indicator Jig Dept.

In FIGURE 1 is a typical scenario where a power unit that can be turned is being aligned to a static unit that cannot be rotated by hand. Use of pipe wrenches, chain tongs and the like to force the rotation of said equipment carries a death penalty. Well, OK; just fired. The bare shaft is too small, or too close to the opposite shaft for a practical face reading, so the face reading is determined by a second indicator button positioned on the surface...
