Are you someone who is in love with pinewood derby cars and you would like to make sure that your derby car will become as fast as possible? Well, if that is the case, you’ve come to the right place. No one argues that you can build a fast pine car, but building the fastest one possible is yet another story.
Here are some tips that will help you with achieving that:
1. Minimize the friction of the axles and wheels
It doesn’t mean that you will only need to focus on these 2 in order to get the car running at its top speed. What you need to do is to thus polish a bit the wheels and the axles which will in turn reduce friction and thus give you a boost in speed. But make sure that when you will do this, you will use the right materials and equipment. After you will be over with this process, it’s important that you will check to see if they are balanced. Rolling the car on a flat surface will allow you to tell if there are any problems with it or not. Tweaking your car this way should be done ahead of the day the race will be due, so that you have enough time to fix the damages should you have to deal with some.
2. Use a gradual approach when sanding
You will not make your pinewood derby cars look more attractive by sanding and painting them, but you will also reduce the air friction. Keep in mind that while you will be sanding your car, you will need to reduce the fineness of the sandpaper step by step.
3. Don’t underestimate the power of a good paint
After you will make your pinewood derby cars feel as smooth as baby’s skin, you will need to paint them. 1 coat of white primer should be added first and make sure that you cover your car well enough with it. The 220 grit paper sand-paper is an excellent choice in order for the surface of the car to be left perfectly smooth. After this process will be done, you will need to add a few coats of paint to the vehicle’s body. Adding 1 or 2 heavy coats is not recommended. They will not only take a long time to dry, but they will also add up a lot to the total weight of the car.
4. Align the axles and wheels
There are many methods through which you will be able to align the wheels and axles of your vehicle. Make sure that you take into account the difficulty of a method before you will do anything about it. For instance, not all methods are optimal for the Cub Scout.
5. Use the trial and error method
There are a few actions that always provide a boost to your pinewood derby cars and they number:
1. Using high quality wheels & axles
2. Are-polishing wheels in need of a new smooth surface
3. Testing out the axles and wheels until they’ll roll true
With these tips for your pinewood derby cars it’s certain that your next project will be a successful one. Good luck!
