What to do in your Pinewood retirement? (warning: Pic intensive)

My son's last and only Pinewood Derby was last year. In part, thanks to the knowledge shared here, it was a good run, and he got to race in the District and Council races where he finished well.

This year I was planning on no pinewood, but in talking to my friend I found that last year his son Ben's car barely got to the finish line and obviously didn't place well. I agreed to help with a goal of imparting a little theory and knowledge and maybe winning a few races. I told them to shape their block and hand it off to me so I can do a few operations before we got together to final assemble and lube up. They did a great job shaping (but cut the length a quarter inch short, and used the block backwards from what I would have preferred). That was the simple stuff though. I found that Ben must have been issued the heaviest block ever!

Not wanting a challenge to get the best of me, I did the best I could at making the block competitive (including some major surgery).


Result: Ben took second in his pack. (First place was my friend's son who had the fastest car at Council last year...but needed a little help from me this year...but that's a story for another time)
I also worked Ben's sister's car a little for the Family Race, where she came in 2nd. (First was my friend's daughter...same one as above).


My son is now a Boy Scout. Because he joined Cubs late (his last year of being Cub eligible), he was assigned to a Webelo's 1 den that is doing now their last Pinewood this year. So we're going back to help with the builds and run the races in a couple of weeks. One of build we're helping with might be the challenge that is even too much for us. Bryce heard us talk about Speed Theory, but decided to go his own way;



...and if that wasn't enough, I took someone's cast-off scrap, and decided to try to make a competitive car out of it.



Wish us luck and stand by for the follow up!
 
ChrisF-

First sorry to hear you only had a short time with your son in the PWD racing... League Racing? It sounds like you fit in here well!!
idea


With this said it seems your not done by far.. Your time in helping other Scouts is OUTSTANDING!!!! This is what it is all about helping out and doing what you can to keep the spirit and sport alive in those who do not have the time or tools and know how to make it across the finish line...

The cars and how you come up with something out of them is a strong desire to achieve and you are in the right spot to do very well... It is cool to see the pictures and read the stories...
peace
.... Keep up the great work and mentoring other sons and fathers.....

Please make sure to get a pic of your daughters car out of the bag it seemed to look just as cool.... and We would love to thear how the other car turns out...

Papa V
 
Thanks for the kind and encouraging words.
It was a short but fun career. I think we both enjoyed the working together the best. I've kicked around the League racing thought for a while...but I have so many other iron's in the fire that it'll have to be my son that drive's that one forward for me to get it by the wife.

The pink car was my friend's daughter's car. (Ben's sister). Unfortunately, I snapped the shot as an afterthought, and the car is now out of my hands.
I just realized something...last year, we built 6 cars on our way to the Council races. This year, I'm already on my way to building 6, with a possibility of more if anyone decides they want a redo to go to the Council races.

While I might have lent a hand on those 6 cars, folk here like yourself, 5Kids and John H have influenced many times my six by freely sharing your information.
 
You might calibrate your scale- I have seen some high weight blocks, but the grain is usually much tighter, to have that much weight after cutting so much away is cause to check your scales. A nickel is exactly 5 grams. 20 is 100 grams =3.5274 oz.
 
Retirement??? PWD??? What??? Ya NO WAY...Im with Papa V...sounds like the PWD bug has bitten you and we should see you at the next NPWDRL race...Right??? Cool see ya on the track... As far as toomany things going on, well WELCOME to the club my friend...
 
ChrisF, Thanks for your work helping kids enjoy PWD. There's always room here for one more like you.
 
I agree with Papa V, that car seems too heavy with the pockets you drilled out. But great story. Welcome to the addictive hobby. Grab a seat and hold on for the ride.
 
Thanks again all!

Sadly the scale is calibrated and operating as it should. That was just a HEAVY piece of wood.

I'm having fun with the Vampire Stake and the piece of Beaver Chewing Gum. Pack Derby is in a couple of weeks, so I'll keep the lid on the updated pics in case the competition is watching (you know how them tech savy kids can find anything on the web). I promise I'll update you after the race though. I shot myself in the foot once already this year by being a little too transparent and generous (if there is such a thing). It does makes for a pretty funny story though.
 
The knowledge has been shared with Cubs and parents and will continue if any make it to districts and council. But with the helping mostly done and the kids hopefully applying the lessons, it's now about stealth and surprise
ninja
...and having a bit of fun.
Hey...here's a cool video I found;

Cool tip!

TX,

You are the best!

Along with BR and Kinser of course.
 
I had some time to work cars this weekend. Here's the update on one of the builds;
Just needs wheels, axles and tuning.


I was concerned about the aerodynamics (and my weights falling off), so I added a fairing.


Here's she is with the wheels and axles mounted for bringing her up to weight. Still a penny short. Will add that and some putty and do some tuning.


What do ya'll think? Will this dog hunt?
 
Chris, If you have not added a hidden sheet of lead in the piece of wood, something is very wrong.
hmmm

If that wood is close to pine, and that thin, you would be adding at least 20 nickels for weight. You show the equivalent of 7 or 8. Not adding up?? Did you check the scale with about 20 nickels?

Doing the zero tare is not the same as a calibration. If the wood IS that heavy, then you can't move your COG back to make the fastest car possible- so as it looks in the photo- you might have a pack winner, but not near the speed you could achieve. If it isn't pine, why not??
 
It's a piece of pine that was cut off a BSA block during the pack workshop day and thrown out (and I scavenged it for this project). It was hand sawn by one of the cubs, and I laid down a layer of epoxy on the top to even it out a bit so I could work it (and because it was so thin in some area's I was worried about the structural integrity). I think I should have used a lot more epoxy though. Oh, I almost forgot, I did use wood from a clothespin to build up the front because it was so thin (I wish I would have grabbed more of the pine scraps from the workshop, but oh well, you use what ya got on hand). Could that have added that much to the weight? For you mom's reading along, I did ask my wife first for one of her old clothespins which she reluctantly gave me.
txchemist, I think you're trying to tell me nicely that I need a new scale!
sick
I couldn't check the scale with 20 nickles because that was all the spare change that I had...49 cents. 20 nickles make a dollar, and my kids make sure I don't have that much laying around the house!

If I sent it in for league racing, what division could I enter it in?
 
Might just need new batteries. I have a habit of forcing nickels to show up in my change all year long. I also get the Cubs I'm going to help start doing there chores at home and saving up their own nickels.
