Derby Dust Hub Shaver

Home » Derby Dust Hub Shaver

Possibly the most over looked tool on the market right now.  Nearly 10 years into the wheel molds, nearly every wheel has some sort of flaw.  Most common flaw to date that will cause wheel wobble will be the uneven outer hub.  Pictured are two factory flaws that are pretty common even with the “best” of molds.  This uneven surface causes uneven rotation, which translates to wheel wobble.  You are in luck, there is a DIY tool that will fix this.  The Derby Worx Pro Hub Shaver.

What we have done is resurfaced this hub for a smooth, flat,  parallel surface to the bore.  We also widen the overall diameter than just a smudge to ensure that the head of the axle does not rub against the wheel.   Note the lower step of the hub is never in contact with the axle other than at the inner bore.  The only part that matters is the upper step of the hub.  Below is what we do with our CNC lathes.  It can be mimicked with the Pro Hub Shaver.

The Derby Worx Pro Shaver is that tool that will clean up these factory flaws.

There are a problem with the BSA Wheels. I have very limited amount of sets left that are machinable that do not wobble.
Matched inner bore will not be available. #15 molds are no longer premium wheels. Please watch this video:

Just to be clear, I do not sell wheels that wobble. I will not sell junk wheels. I rather have no sales, than have my name associated with junk wheels.
The wheels that you see in the video are thrown away. They are not used.

BSA is aware of the problems, I am the second person to file formal complaint. Just remember I buy from same place you do.
I have been instructed by national scoutshop not to place another order for wheels. So at some point I will run out. I have no special inside line for a better product.
