The Pro Wheel Mandrel is designed with several benefits, which will help build better Pinewood Derby Cars. A. The Pro Wheel Mandrel is designed with a centering cone made into the screw assembly, this allows for the best centering of wheels for any form of tread treatment the builder prefers. This provides a great work center for lathe cutting wheels or finish polishing after using the Pro Wheel Shaver. B. The Pro Wheel Mandrel has a step cut in the body of the tool for mounting B.S.A. wheels in reverse for treatment and polishing of the inner edge. C. The Pro Wheel Mandrel has an easy grip screw that dose not require tools. This makes it easy for everyone to use and fast. Race Fast Racer X www.Derbyworx.com |

RacerX,
My new pro mandrel tool is not true. The part that is chucked up is fine, but the threaded part has quite a bit of runout. I tried to tweak it a little but I couldn't get it to dial out. Would like to swap with a new one. If the piece was made out of steel I think it would be better. The tool is a vast improvement over the BSA item!

How are you measuring it for true and are you using a scroll chuck or a collet?
As long as the shoulder of the mandrell is perpendicular to the centerline of the mandrell, all the screw is doing is securing the wheel in place. We use them for many processes here in our shop but we will true the shoulder once it is mounted in the lathe for accuracy to that set-up. If you would like it replaced, contact your retailer, we never question customer satisifaction.
Also, hit it with a magnet, it is steel.

Racer X,
Does your machine shop use the Pro Wheel Mandrel to make the new Ultra Lights or do they use a much more sophisticated wheel holding device?

We use the Pro Wheel Mandrel for a lot of work we do, but once you start working at 1 gram and below is a whole new world of speciality stuff.

This weekend I got my Pro Wheel Shaver XT. I set up a rig using my drill press, a regular mandrel (not the Pro Wheel Mandrel yet as I have just ordered mine) and a clamp. I was able to true my wheels more comfortably and quickly. I would suggest going very small steps as on one test I got a bit too aggressive and snapped the mandrel that I was using.
I was thinking that maybe if the mandrel thread were only on the bottom 1/2 inch or so of the pin then a larger diameter of steel near the head where the wheel is mounted could provide a bit more strength in this tool. Any thoughts on this?
My "rig" may not be 100% aligned but it did produced VERY consistent turning wheels with no high spots. I noted that the spring would sometimes back off a bit when I was turning the wheels on the shaver by hand. When running it on the drill press rig I could maintain a slight pressure ensuring the wheel continued to be cut in each rotation. Again... go slow and check often.

Would you willing to post some pictures of the set up ? Lucky 13 |
