Item details

Fast winning pinewood derby car designs utilize polished speed axles.

Utilizing proprietary straightening, cnc machining, and polishing techniques, we produce consistent quality speed axles time after time. Take a look at our pictures of our quality work of pinewood derby axle close up pictures. They say it all! Our feedback speaks for itself. We are new to Etsy, we have 100% feedback rating over 3 years on Ebay.

There are 4 parts to making a CHAMPION.

· AXLES - Reduce friction through polishing

· WHEELS - The lighter the wheels, the faster a car can travel

· COG - Proper weight placement to maximize Potential energy and car travel

· TUNIING - Proper tuned car runs straight down the track! Not side to side.

This listing is for :
Two axles are bent at 2.5 deg (for rear wheels), one axle is bent at 1.5 deg (for front dominant wheel), and one axle is straight (for raised wheel).

What is rail riding?

If a pinewood derby car is aligned to run straight, but the track is not consistently level (very common), the car will contact the center guide rail both with the left wheels and the right wheels. it will basically wobble back and forth all the way down the track. robbing you of all your speed. If a raised wheel is used, then the raised wheel will likely contact the guide rail and start spinning. This will cancel any benefit attained from the raised wheel.

Derby Worx came up with the idea of riding the center rail. Riding the center rail keeps only one wheel touching the track and keeps a consistent travel down the track. If you are not moving back and forth, then you must be moving forward! Faster!

To compensate for the unknown condition of the track, the car can be intentionally steered such that the raised wheel does not contact the guide rail. For this discussion, we will assume that the left-front wheel is raised (if the right-front wheel is raised, then everything discussed below is reversed).

Adjust the right-front wheel so that the car drifts to the left - this keeps the left-front wheel from contacting the guide rail. With this drift, and if the rear wheels are aligned to run straight, then only the right-front wheel will contact the guide rail. To ensure that the right-rear wheel stays off the rail, the right-front of the car can be narrowed by 1/16 inch.

Tests show that when this Rail-rider technique is implemented, car performance is consistently faster than straight alignment.

We have saved you both time and costs because you do not have to purchase the tooling.

Your choice of polish level depending on your desire. Our technique is perfected and you can see the results. Quality and Repeatability time after time.

•Works with ALL DRY LUBES!

You are going to spend THE BIG BUCKS on a set of axles, then protect them. BUY a #44 drill bit so that your axles will be installed the direction you need them to go. STRAIGHT! Have you ever hammered a nail and it goes in STRAIGHT and not BENT? Why would these nails be any different? Drill a guide hole, the axle will follow!

Minimum surface removal to ensure consistent diameters throughout the shaft. Tapered axle heads to reduce surface friction. No cheating with polished waxes that could easily become brittle and break off! This is a real metal polish job. We use a few fancy machines and then good old hands on skilled AMERICAN labor. Each axle is individually inspected by two separate personnel to ensure the HIGHEST QUALITY. Be confident we get it RIGHT the FIRST time.

Our prepped have been deburred, shaped, straightened and sanded down to a 2000 grit finish. From that point, each axle goes through a buffing process up to 100,000 grit MIRROR FINISH! We use separate buffing wheels to ensure no cross contamination. Yes it does matter!

Then we coat the axle with a pinewood derby friendly sealant. Why? Because polished metal will rust if you do not seal it. Through our professional, industry leading, lubrication resources, we have found a substance that binds the fluorocarbon - Krytox to metal. That's right a metal sealing agent that has one of the most friction less substances known to pinewood derby racing.

Our sealant is not an oil, rather an Krytox based solvent that instantly dries and seals the surface of the metal. It can be used with oil based lubes as well as dry lubes.

It doesn't "look" dry. It is DRY

These axles are not only FAST, they sound FAST. How do you know? Because they are nearly quiet when the wheel is spinning!

Axles are wrapped in tissue paper to ship to ensure that your axles are not scratched up during shipping process. They are also shipped with a desiccant to ensure that we eliminate all potential problems. Why? Because we care about our product. We are proud of our product.

You can't even buy 2 of the tools needed to do this for under $25. Much less the files sandpaper, sealer, and buffing materials.
RESULTS. We are getting average speeds of 12.45+ feet per second out of these sets or 2.47's or less on a 30.75 foot metal track with DRY LUBE!
