The Laser Bore Alignment System Components 

 

Model L-705 Laser  

The L-705 Bore Laser is a battery-operated, 

visible light laser that mounts magnetically in a 

bore fixture or mounting. It is suitable for 

almost all bore applications. The laser has two 

mounting surfaces: 0.7498 in. (19.04 mm) and 

2.2498 in. (57.14 mm). The laser beam is 

centered to both mounting ODs to within .0003 

in. (0.08 mm). The L-705 laser beam is 

designed to shoot up to 110 ft.  (33 m) but has 

an angular adjustment resolution of .001 in. 

(0.025 mm) in 50 ft. (15 m) and is best used 

under 50 ft. 

  

Model L-706 Long Distance Laser  

For long-distance applications that exceed the 

range of the L-705, the L-706 Laser is equipped 

with the finer angular adjustments necessary to 

set the laser beam to the center of the far 

reference target. It is used for applications up to 

110 ft. (33 m). The finer angular adjustments 

mean there is less adjustment range, which 

make the L-706 difficult to use in shorter distances.   

 

The following describes the operational features of the laser. These features include bubble level vial 

orientation, micrometer values and settings, ON/OFF switches and the external battery pack. 

 

 

The ON/OFF slide switch

 has a lighted LED to indicate that power is ON. 

 

The Pulse/Continuous switch 

selects the laser mode compatible with the readout/interface being 

used (see Page 6 for more information about Pulse/Continuous modes and the readouts used for each 

mode).  

 

Battery Pack connector 

accepts a slip-fit probe with a flexible cord.  

 

Bubble level vials 

on the laser mounting flange are used for rotational accuracy. When the bubbles 

in the level vial are centered horizontally, all micrometer adjustments (controlling laser beam angle) 

will shift the laser beam vertically or horizontally with reference to the bore/target axis.  If the 

bubbles are not centered, any micrometer adjustment to one laser axis will change the laser beam 

position in both axes. The levels also provide fixture mounting repeatability (assuming the laser is 

hard-mounted to fixture). 

 

Micrometer controls 

are provided for the adjustment of the angle at which the laser beam emerges 

from the precision ground, mutually concentric steel laser housing.  Each laser has a NOMINAL 

setting for both the V-Vertical and the H-Horizontal micrometer controls.  The nominal settings are 

determined at the factory and correlate to values for the laser beam when it is perpendicular to both 

the 2 in. and 4 in. mounting faces. When the bubble in one of the level vials is centered, a nominal 

setting of each micrometer squares the laser beam to that specific axis. For example, if the nominal 

vertical setting is .120, then setting the micrometer to .120 sets the laser beam square to the vertical 

axis. When a laser is mounted in the gearbox or bore adapter, vertical and horizontal micrometers 

should be 

set in the nominal positions

 to facilitate the alignment and measurement process.
