Mold Match Pinewood Wheels BSA Stock Factory #2 6 9 Mold

Mold Match pinewood derby wheels are a necessity for the fastest set of wheels.  The thought process behind the theory is that identical wheels will have identical flaws.  If the wheels are identical, using pinewood wheel tooling you can then make all the wheels turn in unison.  When all the wheels are turning the same, then there is no wasted energy thus making a faster car.

You have done your research.  You know these the Mold Match Pinewood Wheels #2 6 9 Factory BSA are one of the best selections to start with.  If you have to be 100% stock or want a good set of mold match wheels to start your project, these are the ones. After two years of sorting them out we finally have enough to start selling as a stand alone product.  No sorting, spinning, no measuring, nothing done to them.  We simply sort them out.

Concentricity of bore to outer wheel diameter is another important feature.  This is where a true wobble will come from.  Most wobbles are due to friction and are easily remedy with a little lube.  A true wobble is because the concentricity is off meaning straightness of the inner bore in correlation of the major outer diameter (axis) is slightly off.  Most errors probably occur during the ejection and cooling process.  Best Pinewood Derby Stock Wheels #15 Mold normally have minimum concentricity issues and thus have little to no wobble.

About Pinewood Derby Wheels

And just for general knowledge. These parts (wheels) cost about .02 to make (if even that) . No one really knows the rejection process.   I am more than certain, there is no real quality control other than does it look right.  Just remember that the wheels never begin with good quality control. They are NOT perfect, and never will be. Derby Wheels are Injection molding.   Hot plastic fills a mold.  Each mold is different.  Every wheel is different.  No matter what modifications are done to them, they are not precision wheels. You have to accept that.  If you play with enough wheels, you will note there are now flaws in every wheel mold.

  • Set of 4x wheels
  • Any manufacturing imperfections are assumed
  • Derby Dust will not be responsible if you feel the wheel is “junk.”
  • Derby Dust Tech’s do not presort or inspect these wheels for flaws.
