(3 m) can be achieved. The L-708 provides a straight reference line to which any bore can be aligned and measured. The laser mounts in an adapter, and the laser and adapter are then mounted in either the bore or the counter bore of the gearbox spindle. -
Page 7: Starting An Alignment With The L-708
Starting an Alignment with the L-708 To start the alignment, it is important to make sure the L-708’s angular adjustments are in the center of their adjustment range. There are two indicators to aid in setting the adjustments in the center of their range: 1. -
Page 8: Adjusting The L-708 Laser
Adjusting the L-708 Laser In a typical bore measuring application, the L-708 Laser is mounted concentric to one end of the bore by means of a bore adapter. The L-708 laser beam is concentric to its 1.2495 in. (31.74 mm) OD mounting surface to .0003 in. -
Page 9: Replacing The Batteries
Replacing the Batteries The battery pack uses two 9-volt batteries, housed in a two-part case 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. - Page 10 3. Attach the counter weight at the end of each pole and use the thumbscrew to tighten the counter weight to the poles. 4. An extra counter weight and pole are included with the A-514C. Insert the pole in the main counterweight and use the thumbscrew to tighten.

Page 12: The A-514 A, B And C Self-Centering Laser And Bore Adapters
The A-514 A, B and C Self-Centering Laser and Bore Adapters The A-514 self-centering laser and bore adapters accurately and quickly position the laser and target on the bore centerline. The adapters can be centered to the bore to within .0005 in. (0.0127 mm). The adapters have adjustable legs that allow them to be used for bore diameters ranging from 3.5 in. -
Page 13: Assembling The Bore Adapters
Assembling the Bore Adapters The A-514A, B and C Bore Adapters are all assembled the same way. Each adapter consists of two legs that cross each other, forming an “X” shape. Using a bolt and Allen wrench provided, screw the bolt down and tighten. -
Page 14: The A-514Gs And A-514Gl Leg-Setting Gage
The A-514GS and A-514GL Leg-Setting Gage The gages are used to set the A-514 Adapter legs to the correct bore diameter. The gages are available in two sizes, depending on the size of the bore being measured. The A-514GS is used with the small (A- 514A) or medium (A-514B) bore adapters. -
Page 15: Setting The Legs For The A-514Gs (Using Small And Medium Bore Adapters)
Setting the Legs for the A-514GS (Using Small and Medium Bore Adapters) Example: (see Figure 7) 1. To measure a 6 in. bore, each leg must be set to 3 in. 2. Set the caliper to read 3.000 in. 3. Twist the locking nut on the caliper so it does not slide, then insert the caliper inside the hub on the leg setting fixture. -
Page 16: Setting The Legs For The A-514Gl (Using Large Bore Adapters)
Setting the Legs for the A-514GL (Using Large Bore Adapters) The large leg gage can be used for all three bore adapters. When setting the legs for the large bore adapter you must use the fixture extension. Example: (see Figure 8) 1. -

Page 18: Model R-358 Computer Interface
The R-358 computer interface provides exceptionally high accuracy (.00004 in. resolution) for downloading target data to Hamar Laser’s alignment software. The interface attaches to the computer with an RS-232 cable and it is powered by a lithium ion battery for long life and usage. An AC adapter/charger is provided, and the unit features LED charging and power indicators. -

Page 21: Bore9 Software
Bore9 uses the NORMIN method developed by Hamar Laser to quickly and precisely cancel out these errors and eliminate the need for complicated, expensive fixtures. The word NORMIN is a contraction of NORMal-INverted, which briefly describes the method. -

Page 26: Appendix A - The Normin Method (Bore And Spindle)
Appendix A – The NORMIN Method (Bore and Spindle) The NORMIN method was developed by Hamar Laser Instruments as a way of com- pensating for laser or target mounting errors in bore or spindle work. The word is a contraction of “NORMal- INverted,”... - Page 27 The readout always shows the displacement between the Target Center and the Laser Beam Center. When the Target Center is not on the True Bore Center, the numbers and the signs on the readout will change when the target is rotated because the Target Center is moved to a different location in relationship to the laser beam.

Page 28: Appendix B - Calculating Bore Diameters
Appendix B – Calculating Bore Diameters Once the measurements have all been taken, a few simple calculations will provide detailed information on the internal diameter of the bore. Due to the design of the target and the NORMIN procedure, it is necessary only to know the reference diameter in order to calculate bore size at each measured point. - Page 29 Plotting Measured Data The following chart and calculations are provided to help record, calculate, and plot bore diameter data. The chart can be expanded to record as many measurement points as are required. Formulas for calculating offsets and diameter are provided, as well as a sample plot of readout data (see Figure 20 on Page 27).

Page 33: Appendix D - Care And Cleaning Of Target Optics
Appendix D – Care and Cleaning of Target Optics The proper care and cleaning of optical windows and/or lenses of Hamar Laser’s position-sensing devices (targets) assures optimum performance. Contaminants on an optical surface increase scatter, absorb laser energy, and eventually degrade the accuracy of the position-sensing devices. Because cleaning any precision optic risks damaging the surface, optics should only be cleaned when absolutely necessary.
