Aluminum Oxide Polishing Procedure for Brunswick Laminate Lane Surfaces

Materials and Tools Required:

  • *180 Grit 3M Black Sanding Disk for Rotary Sander
  • *320 Grit 3M Black Sanding Disk for Rotary Sander
  • Rotary Buffing Machine
  • Rotary Buffing Machine Sanding Pad

* One sheet per pair

Area to be Polished

The entire lane is polished unless the pine is the early configuration, non-laminate printed pine. At centers having printed pine, only the maple laminate is polished.

At centers having maple and pine laminate, the lane is divided into three sections. The first section is maple, the second section is 1-1/2" pine panels in the center of the lane, and the third section is the remaining pine laminate.

1. Clean lane with a lane duster starting at the foul line with a clean surface. Ratchet duster at pin deck and pull back to foul line.

2. Clean entire lane. A vacuum lane stripper is recommended for this procedure.

NOTE: Using a combination machine make sure it is on stripping only.

Polishing Pattern & Procedure

Use a crossing pattern in the first 8 feet of the first section as shown in figure 3 until you hear the noise from the screen begins to dissipate. From there going with the lane at a slow but steady pace, polish the out side right through the section and return back towards the foul line in the left track area. Proceed down the outside left and return up the right-hand track area as shown in figure 2. Continue back down the middle of the section to the next section and use the same pattern there. After completing all sections polish straight back to the foul line through the middle of the lane. At this point flip the screen over and use that side for the next lane. After completing the procedure with the 180 grit repeat using 320 grit disk.

Cleaning Procedure:

1. Clean entire lane with a duster.
2. Strip entire lane with a vacuum stripper.
3. Condition lane.

NOTE: The screens should be "burned "before using. This can be done by quickly running both sides of each screen against a concrete area to take the edge off the screen. When starting the buffer it is a good practice to pull the buffer across the lane. This avoids scratching the surface during start up.

DC Drive Motor Maintenance

All Kegel lane machines are driven by DCV drive motors that are designed with two carbon style brushes, one on each side of the motor.  As the brushes wear down over time, carbon dust particles build-up inside the head of the motor between the stator (field) and the rotor (armature).  This build-up can cause a short inside the motor.  To prevent a dangerous build-up, it is important to routinely remove the carbon brushes, and blow out the motor with air to remove any carbon build-up.

Note:  If you use an air compressor, please insure that the air-lines are free of moisture before evacuating the motor.

If the brushes are several years old, they may need to be replaced.  Each brush is manufactured with a tension spring that keeps the brush in constant contact with the rotor of the motor.   The shorter the carbon fiber brush becomes the less tension there is on the rotor.
