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.

HOW DO WE DO IT?

Minimum surface removal to ensure consistent diameters throughout the shaft. Tapered axle heads to reduce surface friction. 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.

Then we coat the axle with a metal binding nano sealant. Why? Because polished metal will rust if you do not seal it. Sealed with a plastic friendly nano sealant ensures crazy spin times and a near friction-less surface.

Works with ALL DRY LUBES!

Tech Note: DO NOT HAMMER BENT AXLES. BENT AXLES MUST BE TWISTED OR PUSHED IN.

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!

FINISHING THE CHAMPION AXLES

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

eBay is an extension of our marketing campaign, not a flea market for our "junk" products. Our "junk" gets thrown away. We do accept offers, but please do not insult us. Offering bids at 50% off is an insult and will not be answered. We are very proud of the quality of our products and will continue to do business this way. Our products are made in the USA with those funds staying in the USA, always!

Due to the rising costs associated with doing business on eBay, including higher than ordinary payment fees, we are forced to charge a higher price on our eBay offerings than you would be able to purchase them from our company elsewhere. We apologize for this but the costs have become prohibitive and we find it necessary to implement this policy. We find this necessary and want to advise all our eBay friends of this new policy to avoid any complaints in the future should you find our merchandise elsewhere on the internet at lower pricing. You placing an eBay order constitutes acceptance of our policy and these higher costs. Thank you for your understanding.

When placing an order via eBay, you will have many payment options at checkout including PayPal, PayPal Credit, Credit Card, Debit Card, Apple Pay & Google Pay.

Combined Shipping

We are a firm believer in combined shipping costs to get you best price possible. However…. eBay system is horrible at combined shipping.

To request an invoice from me that combines shipping please use the Cart feature in eBay to add items until you are done. Then hit the Request total from seller button. If you don't do it this way eBay will force, you to make immediate payments for each item you buy and you will be charged excess postage in many cases. If you buy from me and this happens accidentally, I will refund any excess postage back to you with PayPal.

This works for Buy It Now auctions. On regular auctions you should still wait to pay until all your auctions are finished and then request an invoice from your seller. eBay always sends an Instant Invoice after you win an auction, but you should not pay immediately if you intend on combining shipping to save money. The link to contact the seller directly has changed. Now it is the "Contact seller" link which is under the seller's name upper right in the Seller information box.

We cannot guarantee that your pinewood derby car will win a trophy, but we can guarantee that you will be satisfied with our products. If you are not satisfied with one of our products, within 30 days of receipt of your shipment you may return the product for a refund of the price of the returned items.
