The invention of a device has four threaded bolts that engage cooperatively threaded apertures in a base. These thread bolts hold the device in a temporary yet stationary position. The device has non-magnetic metal which allows test indicators to display accurate results free from any magnetic fields. The device has a precision bore of a nominal size. The radial value of the nominal size precision bore provides for mathematical calculation of the spindle centerline to work piece distance for measuring. The device has undercuts on both of its sides to aid in removing by hand. These undercuts allow the device to pivot from its stationary position for removal without damaging the planar surface. Alternatively, the device has four magnetic inserts, pocketed upwardly from the bottom surface.

Provided is a method of aligning a gas turbine shaft. The method includes securing a laser sensor to a first shaft of a first rotary component axially connected to a rotor of a gas turbine, and securing a laser generating device to a second shaft of a second rotary component. The second shaft is axially coupled to the first shaft and has a central axis misaligned with respect to a central axis of the first shaft. A jogging assembly coupled to the first rotary component is actuated to rotate the first shaft and the second shaft. Measurements representative of a misalignment of the first shaft and the second shaft are received from the laser sensor, and based on the measurements, a central axis of the first shaft can be aligned with respect to a central axis of the second shaft.

An alignment tool for a pile cap is disclosed, wherein the alignment tool comprises: a tensioner configured to apply tension to a cord; a pile cap fastener coupled to the tensioner; and a cord guide coupled to the fastener; wherein the cord guide is configured to guide a cord under tension by the tensioner.
