Answers to Rules-Type Questions
Answers to Lubricant Questions
- Are your parts legal?
- Please read my write-up in Pinewood Derby Rules. The short answer is, "You need to read the rules for your particular race, as they are all different." Some rules are generic and others are extremely explicit. If you have any questions, ask your race manager. I would have no way of knowing your specific rule set and your race manager's expectations.
- Is Your Graphite Legal?
- Yes, it is legal for any race that allows dry graphite.
- Are your parts from the Cub Scout BSA kit?
- If our part says "BSA" in the title, then yes, it is from the Cub Scout BSA kit. Yes, we purchase them directly from BSA.
- What is better, Graphite or NyOil?
- Graphite is tried and true but NyOil has its advantages and disadvantages. Nyoil will stay on your axles throught the races, whereas loose powdered graphite will blow off your axles each time it runs down the track. Our graphite-coated axles are designed to keep the graphite on your axles throughout all your heats, and track tests proved they are faster than NyOil coated axles. Nyoil MUST be used sparingly, only one or two drops! DO NOT mix graphite and NyOil.
- Should I polish the BSA axles I purchased from you?
- Yes, we recommend a light polishing on the BSA axles because they can tarnish over time, even though they are individually sealed in little bags for shipping. We recommend our axle polishing kit that contains pumice (finely crushed rock that creates an abrasive polish), wet/dry sandpaper and full instructions, plus 5 spare axles.
- Do I still need graphite with graphite-coated axles?
- Yes, because you need to work graphite through the wheel bore. Squirt graphite into the wheel bore, spin your wheels and repeat, so it works through the entire wheel bore.
- Are 4 grooves better than 2 grooves in axles?
- No, our PRO axles are precision designed by mechanical engineers. We cut grooves for a purpose. One groove under the axle head removes the corner, so the axle rides flush against the axles head, thereby reducing wobble. The other, wider groove, is strategically placed so it is always in the center of the wheel to reduce friction and so it does not catch the edge of the wheel. Four grooves are a gimmick. Consider this; if 4 grooves are good, why not 5, 6 or 10 tiny grooves!
