The Pro-Wheel Shaver II is designed to create round and true wheels by removing tread material. It is intended for use on wheels made of a relatively hard plastic,such as those offered by BSA,PineCar,Royal Rangers,S&W,and Royal Ambassadors. It is not intended for wheels made of a relatively soft plastic,such as those offered by Awana and PinePro. To use the Pro-Wheel Shaver II,a Pro Hub Tool (not included) and a 5/32" Hex Key (shipped with the Pro-Wheel Shaver II) are required.

Ream the Wheel Bores

1. Test fit each wheel on the Pro-Hub Tool.
2. Follow the instructions with the Pro-Hub Tool to ream any undersized wheel bores.
3. Royal Ranger and S&W Kits Only - Ream the wheel bores by hand with a 1/8" drill bit.

If your kit has narrow wheels (Royal Rangers,S&W,Royal Ambassadors,etc.),skip to "TRUING THE TREAD SURFACE".


Truing The Wheel Edge


4. Slide the Pro-Wheel Shaver II onto the Pro-Hub Tool,until 1-3/16" (critical measurement) of the Pro-Hub Tool is exposed (see Figure 1). Use a 5/32" Hex Key to firmly tighten the Pro-Wheel Shaver II to the Pro-Hub Tool.
5. Loosen the screw holding the cutting blade,and slide the blade towards the Pro-Hub Tool as far as possible. Tighten the cutting blade.
6. Mount a wheel with the inside wheel hub facing the Pro-Hub Tool.
7. While pressing the wheel against the blade,rotate the wheel five complete revolutions counterclockwise.
8. Remove the wheel,and repeat steps 6 and 7 for the remaining three wheels.
   
   

Truing the Tread Surface

Mount Pro-Wheel Shaver II



9. Slide the Pro-Wheel Shaver II onto the Pro-Hub Tool,until 5/8" of the Pro-Hub Tool is exposed (see Figure 1). Use a 5/32" Hex Key to firmly tighten the Pro-Wheel Shaver II to the Pro-Hub Tool.
10. Loosen the screw holding the cutting blade.
11. Royal Ranger and S&W kit wheels only - Slide a short piece of 1/8" brass tubing over the pin or the Pro-Hub Tool.
    
    
    

Mount First Wheel


12. Slide a wheel onto the Pro-Hub Tool.
13. Rotate the wheel and move the blade to identify the highest spot on the wheel.
14. Rotate the wheel 1/8 to 1/4 of a turn and press the blade against the wheel.
15. While holding the blade firmly against the wheel,tighten the blade. Press the blade against the wheel; do not press the wheel against the blade.
    
    

First Pass




16. Turn the wheel counterclockwise and make five complete wheel rotations.
17. Slightly loosen the screw connecting the Pro-Wheel Shaver II to the Pro-Hub Tool. Pull the wheel off of the Pro-Hub Tool and slide the next wheel onto the Pro-Hub.
18. Repeat steps 16 to 17 for the remaining wheels.
    
    
    

Remaining Passes




19. Repeat the previous two sections until the wheels no longer have low and high spots.
20. For the final pass,continue turning until all possible material is removed.
    
    
    

Polish




21. Use a Pro-Wheel Mandrel and wet/dry 600 grit sandpaper to polish the wheels.
22. Additional polishing may be performed if desired.
    

Storage




23. Apply a protective spray coating such as WD-40 or equivalent and store the tool in a plastic bag.
    
    

Important Notes

1. The Pro-Wheel Shaver II is a hand-powered lathe. It removes tread material such that the resulting wheel is round. With a little practice,wheels can be machined to within 1 thousandths of an inch (0.001). Check your local rules to make sure that lathed wheels are allowed in your race.
2. The Pro-Wheel Shaver II is intended for adult use,as it requires adult hand strength to loosen and tighten the adjustment bolts and to turn the wheels.
3. Although the blade does not have a knife-like edge,use care to minimize the risk of an injury. If the blade ceases to shave the wheel,the cutting edge can be restored with a fine honing stone or a fine-toothed file.
4. For best results practice with a spare set of wheels before truing the target wheels.
5. Fine cross-cuts may be created on the wheel tread surface which cannot be completely removed by polishing. These cuts should not affect the performance of the wheel.
