Virtually all pinewood derby molds are made through an injection molding process. This process leaves the wheel bore with a rough surface and with bits of plastic debris.
The Pro-Bore Polisher will improve the speed of your car by reducing friction inside the wheel bore.
- Eliminates plastic debris and minimizes flaws inside the wheel bore
- Polishes the wheel bore to a high shine
- Includes industrial-quality plastic polish
The Pro-Bore Polisher is effective on wheels from Awana, and many others. It is less effective on wheels with large bores such as those used on Royal Ranger/S&W kits. Do not use the Pro-Bore Polisher tool on BSA wheels, MV Wheels, PineCar Wheels or Outlaw Wheels. Instead, use a pipe cleaner and the bore polish without the tool.
In addition to the Pro-Bore Polisher, a pipe cleaner (supplied), 1 micron plastic polish (supplied), a hand drill, and a clamp are required.
To polish, follow the instructions below. Click on any of the small pictures to view a larger picture.
Pro-Bore Tool Usage Instructions
Caution - Some polish may be thrown when the drill is running, so wear eye protection, old clothes, and cover any sensitive equipment on either side of the pipe cleaner.
- Clamp the hand drill to a work surface using a clamp. Do not use a Dremel-type tool as the RPM is too high.
- Insert the solid shaft of the Pro-Bore Polisher into the chuck of the drill.
- Cut a piece of pipe cleaner 1-1/4 inch long.
- Slide the pipe cleaner between the two prongs of the tool. Make sure that the pipe cleaner is centered between the prongs.
- Apply a small amount of polish to the pipe cleaner. Spread the polish onto the entire pipe cleaner surface.
- Slide a wheel onto the pipe cleaner and over the tool. If the fit is tight, use a pair of pliers to squeeze the prongs of the tool together as the wheel is slid onto the tool. NOTE: If the bore of the wheel is too small for the tool, remove the tool from the chuck of the drill and insert a piece of pipe cleaner into the chuck of a drill. Then polish the wheel.
- Hold the wheel and start the drill on a slow to medium speed.
- Move the wheel back and forth on the tool for 5 to 10 seconds.
- Slide the wheel off the tool onto the pipe cleaner and polish for an additional 5 seconds.
- Remove the wheel and stop the drill.
- Repeat steps 5 to 10 for the other wheels.
Important - Do not slide the wheel onto the Pro-Bore Polisher while the drill is running.
- Wash the wheels in water, using a clean portion of the pipe cleaner to scrub inside the bore.
- Dry the wheels. A dry portion of pipe cleaner can be used to dry inside the wheel bore.
