Product Description

Pinewood Derby Car Body – Physics Lecture

This is my go to for any pinewood derby participant.  I can not stress how many happy customers come with this design.  Pinewood Derby Car Body – Physics Lecture is a true statistical winner.  Based on a long college lecture series,  the Tech’s have tweaked it to our final design that we offered for many years.

The Techs at Derby Dust offer this racing design ready for final sanding and paint. We were the first custom shop that offers this college based design principle.  The tech’s have taken the guess work out of this build and offers the Pinewood Derby Car Body – Physics Lecture with installed the weights with a desirable, balanced COG.   This pinewood derby car body will save you a few hours time in your build.  If you have limited tools, this Pinewood Derby Car Body – Physics Lecture is a great first time or kitchen-doable build with a coping saw and drill.  No fancy tools, no complicated scroll cuts.  

The body contains two weight pockets cut from the side.  Techs fill these pockets with molten lead and then cover with wood putty.  Optionally, techs will utilize two under pockets if tungsten is chosen as a weight ballast.    Pinewood Derby Car Body – Physics Lecture is cut using CNC machines to ensure a repeatable product.  As of 2019, Derby Dust will no longer offer the car with the front end notched between the wheels.  Some inspectors my not pass a car due to the 1.75″ ruling.  Derby Dust still recommends shaving 1/16th off the dominant steer axle to ensure the rear wheels do not rub.

Combine Shipping Instructions

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.

Due to the rising costs associated with doing business on eBay, including higher than ordinary Paypal 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. Your placing an eBay order constitutes acceptance of our policy and these higher costs. Thank you for your understanding.

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! 

Combined shipping is calculated by taking the highest shipping charge and adding $0.25 for each additional item.  If you think these are unfair shipping prices, just remember I did not decide to charge for shipping fees.  Read statement above.  Please follow combined shipping instructions here:
