Pro-Outer Hub Shaver

Wheel Accuracy = Greater Speed!

The Pro-Outer Hub Shaver is a precision machined instrument that will improve the speed of your pinewood derby car by:

1. Ensures accurate rotation by aligning the outer hub with the wheel bore for proper mounting on the Pro-Wheel Mandrel.
2. Improves wheel hub to axle head contact by eliminating flaws on the outer wheel hub.
3. Reduces axle to wheel contact by removing the two step recess on the outer hub and slightly coning the outer hub.

Notes:

1. The Pro-Outer Hub Shaver is intended for use on wheels from BSA kits. It is not intended for use on wheels from other manufacturers.
2. A Pro-Hub Tool is required to use the Pro-Outer Hub Shaver.

Test Wheels

1. Remove the protective cap from the square end of the Pro-Hub Tool, and then test fit each wheel by sliding it onto the pin. If the wheel bore is too small for the tool, use steady hand pressure and a twisting motion to work the wheel onto the tool. Remove the wheel and repeat three times on the same wheel.

Mount Pro-Outer Hub Shaver

1. Slide the Pro-Outer Hub Shaver onto the pin of the square end of the Pro-Hub Tool; orient the cutting edge outwards. To minimize the risk of a hand injury, leave the protective cap on the coned end of the Pro-Hub Tool.

Cone the Hub

1. Place a wheel onto the pin of the tool, spoke-side first.
2. With one hand hold the Pro-Hub Tool and the Pro-Outer Hub Shaver, and with the other hand press the wheel against the tool. Rotate the wheel three complete revolutions.
3. Check the outer hub and repeat if needed. But avoid cutting too deep into the wheel.
4. Repeat steps 3 to 5 for the other wheels.
