We have been using the DERBY WORX Pro Hub Tool and Outer Hub Shaver for over three years for Cub Scouts and Pro Racing at PWDR.
First, I suggest lightly sanding the shaft of the DERBY WORX Pro Hub Tool before using. We start with 800 grit and work our way up to 2000 grit. You can get away with just using 1000 grit. Be careful when you are inserting the wheels onto the Pro Hub Tool. Take your time!
Over the years, we have modified the tools to remove the raised surface on the outer wheel hubs and create a "lip" on the outer hub to minimize the wheel hub contact with the axle.
Videos of these tools are shown at the following link: [http://www.derbyworx.com/video.htm]
Note: If you modify the DERBY WORX Outer Hub Shaver, take your time and just remove a little material, from the tool, till you get the outer wheel profile that you desire.
If you are using this"outer hub" procedure on 1 gram wheels, you have to be very, I repeat, very conservative with removing material from the outer hubs or you can weaken the wheel.
DERBY WORX Wheels already have this raised lip machined into the surface so you don't have to do this procedure on these wheels.
You might want to get several of these Outer Hub Shavers just in case you don't attain the right outer hub profile with your filing/machining when you do this procedure for the first time.
Test the Modified Outer Hub Shaver on some wheels that you can discard if you do not get the right profile on the tool.
Here is the Pro Hub Tool, modified Outer Hub Shaver, and Wheel before creating the lip.
Note that the Outer Hub Shaver has been "ground-down" on the right side in the picture. The side of the shaver that is "ground-down" will not do any cutting.
You will be rotating the wheel in the direction of the raised section of the Outer Hub Tool. This is the area that will be making the profile.
Here is the wheel after creating the lip with the DERBY WORX Outer Hub Shaver.
This outer hub should be lightly polished with 1000 grit sandpaper after creating the lip. This wheel hub has not been polished with sandpaper in this picture.
