Critical Note on Calibration
When configuring the R-1307 Readout, it is critical to match the target ID with the target ID
identified on the serial number of the target. For example, if the target ID on the target serial
number label is 2, then the R-1307 must also be set to the number 2. If the target and readout and
not matched, a centering error of up to .004 in. (0.10 mm) can occur. In addition, the laser switch
setting (CONT. or Fixed vs. PULSE) must also agree with the R-1307 Readout setting (F10.10 vs.
P10.10).
For example:  .. or  .. for R-1307 #2
For more information on the Pulse/CONTinuous modes on the laser, see Pulse/Continuous Modes (L-705
and L-706 Lasers) on Page 5. For complete information on matching the target to the readout, see
Configuring the R-1307 Readouts on Page 9.

The L-705 Hinge Line Alignment System
Hamar Laser’s Hinge Line Alignment System has been a proven performer in the aerospace industry for
many years. In fact, the first hinge line system Hamar Laser delivered revolutionized the industry by
reducing an 8-hour job, requiring eight workers and four theodolites, to one that took only two workers
less than an hour to complete. In addition, accuracy was significantly higher and the results were
consistently repeatable. Currently, several aircraft builders are using this alignment system to accurately
align hinge-pin bushings in tooling fixtures and vertical and horizontal stabilizers.
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.
The L-705 Laser has been designed with a
standard aerospace tooling diameter of 2.25
in. (57.15 mm). The centering of the laser
beam to the housing is controlled to
extremely tight tolerances, usually less than
.0005 in. (.013 mm). Built-in micrometers
on the back of the laser control the angle
adjustment of the laser beam. These two
features eliminate the steering fixture and a
reference target, making the task of aligning
large floor assembly jigs fast and accurate.
Figure 1 – The L-706 Laser

3
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 4 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.
Adjusting the Laser
The laser beam is factory-adjusted to be concentric to the
mounting diameters (2.25 in. or 57.15 mm and .75 in. or 19.05
mm) within ±.0005 in. (0.0127 mm). With the adjusting
micrometers set at the nominal position, (see the Nominal
Settings label on the outer flange), the laser beam is perpen-
dicular to the front mounting surface and parallel to the
mounting diameters within ±.0003 in/ft.
In a typical bore measuring application, the laser is mounted
concentric to one end of the bore by means of a fixture ring or
plate. Because fixtures are seldom perfect, the laser beam
requires angular adjustment to make it concentric to the bore.
This is accomplished by placing the Self-Centering measuring
target at the other end of the bore and adjusting the mi-
crometers on the laser until the laser beam is centered on the
target.
The circular level vial on the laser mounting flange is used to
reference the orientation of the vertical and horizontal axes of
the laser. When the bubble in the level vial is centered, all
Figure 2–Laser Micrometer Adjustments

4
micrometer adjustments (controlling laser beam angle) will shift the laser beam vertically or horizontally
with reference to the bore/target axis. If the circular level bubble is not centered, any micrometer
adjustment to one laser axis will make the laser beam position appear to change in both axes. The level
vial also provides fixture mounting repeatability (assuming the laser is hard mounted to the fixture).
Only minor readjustments of the laser to the bore and fixture surfaces are required in situations where
frequent alignment is expected.
Attaching the Battery Pack
The L-705 Laser battery pack is a stand-alone unit that
attaches magnetically to an extruder gearbox. The
battery pack has a detachable cord with a probe at each
end. One probe attaches directly to a jack on the battery
pack and the other probe is inserted in the control panel
of the L-705 Laser.
1. Turn off the main power switch.
The main power switch must be off before
attaching the battery pack.
2. Insert the probe into the battery power input
jack.
The jack is located on the end panel of the battery
pack. Insert the plug gently until it snaps into
place.
3. Insert the probe into the laser power input jack.
The jack is located on the micrometer control, at
the apex of the V and H axis arrows. Insert the plug
gently until it snaps into place.
Replacing the Batteries
The battery pack uses two 9-volt batteries. The batteries are housed in a two-part case which is held
together by flathead screws. Hamar Laser recommends using alkaline or nickel-cadmium (NiCad) cells
for best performance.
1. Unplug the battery pack from the laser.
Pull the probe out of the laser jack and gently set aside.
2. Unscrew the cover of the battery pack.
Locate and loosen the two captive flathead screws and remove the cover.
3. Replace the two batteries.
Remove the old batteries and replace them with new 9-volt cells, being careful to orient them with
the negative terminal out (or up).
4. Re-attach the cover.
Put the cover back on and secure it to the battery pack with the screws.
Figure 3 – Attaching the Battery Pack

Pulse/Continuous Modes (L-705 and L-706 Lasers)
The L-705 and L-706 Lasers are now equipped with a PULSE/CONTinuous switch, which manually
switches the laser beam between Pulsed and Fixed Beam Modes. Pulse Mode automatically removes the
effects of excess (ambient) background light for the R-1307 readouts, providing a more accurate reading.
The R-1307 Readout supports both Pulse Mode and Continuous Mode as well as storing up to nine
different target calibration factors for multiple target users. These capabilities must be specified when
ordering a system.
The chart below indicates the operational modes for Readouts/Computer Interfaces that operate with the
L-705/L-706 Lasers:

T-271 2-Axis Virtual Target for Spherical Bearings
The T-271 Virtual Target is
designed specifically for spherical
bearings to align them down to
accuracies of .0005 in. (0.013 mm).
It comes with a bore adapter that is
customized for the specific bore
ID. The target works by using an
optical trick to center the PSD
(laser sensor) axially in the bearing
so the squareness of the bearing to
the centerline will not affect the
target’s measurement of the radial
centering (alignment). This eliminates the need for fixtures to hold the bearing s square to the
centerline.
The target sets up in a few minutes and provides live alignment data via our R-1307 readouts.
With the use of customized bushing adapters, the bore adapter can be customized to most IDs
above .25 in. (6.4 mm).
How the T-271 Target Works
The T-271 measures angle. This
angle is multiplied by a
predetermined length to provide a
center reading. If the angle of the
target is known, the center reading
at any point along the axis of the
target can be calculated. For
example, if X is 100 mm and the
target determines the angle to be
0.01 mm/100 mm relative to the
laser beam, the center reading of
the bearing will be .01 mm higher
or lower (depending on whether it
is a + or – angle) in the middle of
the bearing than at the front of the
bearing. Accordingly, we
customize the target to a known
dimension A, which equals
Z+Y+X.

13
As long as X+Y+Z=A, the readings produced by the target will not be dependent upon the angle of the
target because the effective cell plane will be in the center of the spherical bearing and thus will be on its
pivot point. The center of the bore at the pivot point in a spherical bearing does not change unless the
bearing itself is moved up or down. Therefore, if the center reading produced by the T-271 does not
change when the bearing angle changes, it becomes very easy to align the bearing to the laser beam.
For bores with different widths and diameters, only the length (Y) and the diameter of the adapter need to
change. Therefore, we customize the Y dimension of the adapter to make X+Y+Z equal to A. It is
important to note that the L-705 Laser emitter must be in reference point that is locked on the centerline
and does not pivot. Obviously, it is important to ensure that the laser beam stays on the reference
centerline of the hinge line.

14
