Pinewood Wheel Wobble Test Stand

PRODUCT DESCRIPTION

Pinewood Wheel Wobble Stand

Testing pinewood wheel wobble prior to any derby wheel modifications is a must for a premium fast racer.  Every racer must pay attention to every detail of the derby car.  Pinewood derby wheels are no exception.  Derby Dust Tech’s designed a Pinewood Wheel Wobble Stand for testing such flaws.  0.094″ over sized pin ensures that you can eliminate the tolerance difference that can be associated with wobble testing on regular sized axles. Using this wheel wobble test stand ensures that your inner bore is spinning in the same alignment as the outer tread.

Be sure to only use the best pinewood wheels that you can use.  All derby wheels might be manufactured equal but are not produced equal. The current wheel mold has been used over 10 years to date. Out of round and flawed wheel bores are quite common these days. Mass production with truly little quality control measurements can be seen if you take the time to look for it.

An out of center pinewood wheel can be corrected with machining / shaving.  However a pinewood wheel that is not aligned true to its bore (wobble), can not be fixed and must be discarded if possible.  It literally takes 15 seconds to determine if your wheel is race worthy or is it slated for the younger sibling.

Instructions for Wheel Wobble Stand

  1. Gather 3-4x the amount of wheels than needed.  12-16 wheels for one car is optimal number for the fastest set of wheels
  2. Visually inspect each wheel for manufacturing flaws.  Be sure to inspect inside the bore for flaws
  3. Ensure that the mounting pin has sufficient lubrication to avoid friction causing false wobble
  4. Place wheel on pin, spin wheel at low rpm.  Observe for side to side rotation while spinning.  Discard these wheels if possible.
  5. Repeat for remaining wheels

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.

Shipping Cut-off Times

We ship orders Monday through Friday, holidays excepted. First Class Mail and Priority Mail orders received by 8:00AM MST are generally shipped on the same day.

All orders above $150 will be shipped with signature confirmation. Sorry folks, but need to make sure you get your product. Special requests can be made if you email us and accept full liability of losses. Too many door thieves.

Late Deliveries and Shipping Fee Refunds

  • USPS Shipping – There are no refunds of shipping fees for late deliveries.

Tracking / Order Status

  • For orders shipped by US Priority Mail, a delivery confirmation code should be emailed to you via eBay Website integration. This code can be used to determine if and when a package has been delivered. You can check the delivery status of the package at the US Postal Service Web Site
  • IF for some reason you do not receive the information, please text me to get an update.

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. To minimize the risk of damage, all returns must be shipped in a box.

Returned products must be in original condition, and please include the original order number.

Return of Derby Worx® Tooling
We do not refund tools. Sorry, too many people use the item once and return it for whatever reason they make up. Because of this abuse, it is our policy to no longer offer refunds on Derby Worx Tooling. We do not make, nor do we re-furbish these products. If you need to get your money back, please feel free to list on auction site or create your own amazon account. If Items are defective, we will help you get in contact with Derby Worx for further info on how to use the product or replacement by Derby Worx®.

Download Products
This return policy also applies to ‘Immediate Download’ products. If you are not satisfied with an Immediate Download product, within 30 days from the date of purchase completely delete all copies of the file from your computer. Then send us an e-mail with the original order number, and state that you have completely deleted all copies of the file and that you are requesting a refund.

This is a no-questions-asked guarantee, however, we would appreciate your sharing with us the reason for any dissatisfaction. Thank you.

Feedback is extremely important for all eBay sellers. We strive on providing the best possible experience while shopping with us. If you receive your order within a reasonable time frame and if you do not require any assistance with your purchase then we would kindly request you to please leave us a 5* Positive Feedback rating.
