Derby Talk

I have stopped "turning" my wheels for the run out issue. I do not have a metal lathe. I bought a dial indicator and measured my new wheels. Since I cant my axels I measured the inner rim edge (not inside!). All of my tools had more run out in the chucks than the amount of run out in the u...

Seems unenforceable to me. How are they going to prove the kid (and dad) didn't build a car that looks like the kit? My daughter wanted a NASCAR last year and I would say our result looked just like the kit. Another observation, how long does the inspection procedure take? All these super specific r...

Thanks for reminding me to stay on topic. I like the tape idea, you will not be restricted in your scale options and it rounds to the degree you want. I use The Axe scales. I don't think they are available anymore. They have a dual display that allows the judge and the participant to see the result....

I really don't care what a car weighs, I just care if it is over the limit. The participant wants to know how much, so they can add or subtract a little or alot. But for the ultimate purpose of inspection, it is a pass fail situation. Interesting question is, does temperature and humidity effect the...

I purchased a 5 oz weight. It is THE OFFICIAL RACE WEIGHT. Master of all weight disputes. Only the judges handle this weight. We would tare on this weight then if you got a minus you were under and if you got a plus you were over. I also purchased the appropriate calibration weight for my scale. So ...

Interesting! I do not know.

But the fact still holds. You still want everyone held to the same standard, within your power.

This conversation makes me want to go back to the triple beam. They are just so expensive!

5 Js - everyone should always plan on adding and reducing weight during check-in. Case in point: We thought we would save time by checking some cars in prior to race day, and the remainder on race day. The cars were perfect on the pre-check day. It rained the next day. The next day after was race da...

Unfortunately any time you use a digital scale you are subject to"the roundoff". You must use a scale that is consistent and has enough weight resolution to create your own cutoff point. I was asked at my race, how much over weight we allow. My answer was, 5.00oz or less. We used 3 scales ...

Looks like I missed that thread. Further discussion should follow in existing threads.

I went to the hobby store to buy a BSA kit for a sample. They carry the Revelle BSA Kit. New package, new wheels. The wheels had a painted serial number that caught my eye, and that led me to see these are Made In China wheels. I bought the same Revelle kit last year with the old box instead of the ...

The requirement for the Advanced Pinewood Derby Honor appear to read as 3 cars in the same year (season). One simple, one complex, one non-car car. We (those setting up the rules for the Championship Race) are kicking around the idea of using the 3 classes to offer a race for each type of car. Stock...

:) :) Yes I understand. This is a first attempt at this Championship Race thing. Our organization has not had a Championship for about 15 years. The venues dwindled to one main event open to all clubs an a smattering of individual clubs. Our club is hosting a 2nd event this year with money backed by...

To clarify, there IS NOT a maximum number of cars at the Championship. The stated total is the "expected" total. There are 2 large preliminary events planned and a few small local preliminary events. It may be a larger event in a few years. So, don't let your answers be dictated by "l...

In our organization we have 2 Honors (Patches or Badges if you will) for Pinewood Derby. The basic is build and race A car with other classwork related to woodworking and wheel prep and sportsmanship and how it relates to our Christian life. The Advanced honor goes a bit deeper into all of that, but...

Cool, I'm willing to do that. Thanks for the invite.
