Derby Worx " Pro Bore Polisher "

[RacerX]

The new tools from Derby Worx are here for the 04-05 season.

The Derby Worx Pro Hub Polisher

Inner hub treatment has been limited until now. Many times we have a good wheel, but it just dose not spin that well or lacks what others have. Now this can be corrected and good wheels can be made to spin even better than ever.

The Pro Hub Polisher is designed to use a polishing media that is secured in a tool base for polishing the inner hub. By provide an equal pressure on the inner hub bore while being spun in a drill at a low speed, imperfections from molding are removed and break-in time of a new set of wheels is reduced. This helps in the mating of the surfaces of the axle to the hub.

Any rough estimates as far as improvements in speed from stock bore?

[RacerX]

That is a tough one because to give speed or time improvements would require assembling a car and properly lubricating it, making your runs, which has a breakin effect "this is what the Pro Bore Polisher dose" and recording your times. Now disassemble the car, clean all of your lubricants, polish the hub bores and start over. Way to many variables to be consistant for claims. But I will tell you that under a magnifying loop, you can see a tremendous improvment in hub bore finish and if you have a wheel that is kind of "dead" compaired to others, it will really improve it's test spin performance.

The neat thing about the Pro Bore polisher is that it gives the pipe-cleaner that is used for holding the polishing media a little wall tension against the hub bore for a true polishing effect unlike a pipe-cleaner alone.

I've found I can just use the Pro Tool Mandrel to hold a pipe cleaner in the end that the knurled cap goes on. Without the knurled cap of course.

SSSHHHHHH!!!! People are not to know this. This is how we sell more tools. Lol.

Actually the Pro Bore Ploisher is designed to add a little tension to the pipe cleaner than just a pipe cleaner alone to help burnish the bore smooth.

One trick is to highly polish the pin of the tool before using.

I am not sure that this tool really improves the bore surface. The fit with the supplied pipe cleaners and the standard instructions seems to be too tight. In particular, I was unable to perform this task from the instructions:

6.Slide a wheel onto the pipe cleaner and over the tool.

Once the cleaner is inserted into the notch, the holding arms spread too far to allow the hub to pass over, even if you try to pinch them together. So I tried putting the wheel on the tool first and then inserting the pipe cleaner. While this "worked", it felt extremely tight as the wheel approached the pipe cleaner end of the tool. I was using a variable-speed drill somewhere under 200 rpm when it was turned on and spinning freely. As I moved the wheel down the tool, it nearly halted the rotation at this power level and I had to hold the wheel very firmly to keep it from wobbling. I am concerned that the end of the tool may have scored or rifled the bore surface.

I could not find a video that showed how to use this tool successfully. I am wondering if maybe the supplied pipe cleaners have a wire center that is too thick for the design of the tool, or if they need some fluff removed to fit in the jaws properly. Or perhaps I need to run the drill at a little higher rpm or move the wheel down more slowly. I have no idea what the right tension should feel like during the polish step. And regardless, I could not find a way to close the jaws sufficiently such that it was easy to slide the wheel onto the loaded tool when completely stopped.

Does anybody have experience with this tool? Any suggestions on how the instructions might be revised for successful polishing?

Hi CM,
Thanks for your post.
Here is the link to the DERBY WORX Pro Bore Polisher.

I have not encountered the issue that you are seeing. Make sure that the pipe cleaner is not bent and the ends of the pipe cleaner have a clean cut. Let me know if this helps.

Thanks!

In the old days we used to take a pipe cleaner and bend it in half, then use a needlenose pliers to crimp the bend as tight as necessary to get a nice amount of tension inside the wheel bore. We used toothpaste for our polishing compound. Chuck that in a drill and you're good to go.

I used to think our methods were primitive compared to todays cool tools and techniques. Then we raced my son's car that took 3 months of research and painstaking effort to build with all the latest stuff against my 30 year old car, and I'll be darned if that old thing didn't win!

But the Derbyworx tools are way sexier!

P.S. In the interest of full disclosure, I haven't bought or used the Derbyworx Pro Bore Polisher yet. Maybe I should.

Do to only having 3 days to do my grandsons build and I did not have the supplies one of things we did not do was polish the wheel hub bores or prep them like I would have like to. Thank goodness we won den race, Took first at district in tigers and was 6th out 48 over all. Not bad for our first build. But I assure you next year we will be using the Derby Worx tool on the wheel hubs. I am a firm deliver in every little bit helps!
Thanks
