Shave your hub flat or coned?


Pinewood Hub Wheel Shaver

In addition to truing the outer diameter and the wheel edge, the outer hub that rides against the axle head can also be trued with 2 different tools such as the Pinewood Hub Wheel Shaver.  This modification is needed because the manufacturing process leaves 3 distinct mold marks on the outer hub that are not only visible with naked eye, they also cause additional friction as speed bumps.

Using DIY tooling or machining with a lathe is the best way to resurface the hub or modify the hub in order to reduce the surface area between the plastic wheel and metal axle.  A coned hub is the perfect modification to reducing friction.

Sanding alone cannot remove these marks.  A specialized tool remove these marks the Pro Hub Shaver.  When used lightly, it will remove the mold marks, shaving deeper you can remove the entire hub for tapered axles.  If a coned hub is desired, a modified Pro Hub Shaver is also available.  For best possible speeds, please do not skip this wheel preparation.  Do Not IGNORE the Hub.

Pinewood Hub Wheel Shaver Technical Data

This tool allows the builder to correct flaws in the outer wheel hub, making it parallel to the inner hub and improve tracking of the car. The Pro Hub Shaver is an attachment that can easily be added to the Pro Hub Tool.

  1. The outer hub under the axle head on most wheels is an area, which there has been no good way to correct or polish, the Pro Hub Shaver will allow the builder to remove any high spots in this area that will allow the wheel to not kick when it makes contact with the axle head which in turn will help keep the car tracking straighter.
  2. By truing the outer hub, this will allow the builder to accurately mount the wheel in reverse on the Pro Mandrel and get accurate results like using the Pro Hub Tool. This way the builder can perform any wheel performance tasks they prefer.

Pinewood Hub Wheel Shaver Instructions

The Pro Hub Shaver squares the outer hub on a BSA or Pine Car wheel to the wheel bore. This ensures proper mounting on the Pro-Wheel Mandrel,and eliminates any flaws on the outer hub.

  1. Remove the protective cap from the square end of the Pro-Hub Tool, 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 3 times.
  2. Slide the Pro Hub Shaver onto the pin of the Pro-Hub Tool with 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.
  3. Place a wheel onto the pin of the tool,spoke-side first.
  4. With one hand hold the Pro-Hub Tool and the Pro Hub Shaver,and with the other hand press the wheel against the tool. Rotate the wheel three complete revolutions.
  5. Check the outer hub and repeat if needed. But avoid cutting too deep into the wheel.


Repeat steps 3-5 for the other wheels

NOTE: The Pro Hub Shaver Requires the Pro Hub Tool.
