Re: Graphite selection/testing?

I wish I were 70 again, Stan. You are a youngster. Folks might want to read Chapter 9 - Friction and Lubrication in Doc Jobe's big green book. The graphite from Hodges Hobby House was the fastest at that time. Has something to do with the big flake. My book has a date of 2004. I have been using Hodg...

Re: Help for a newbie

Shawn, I have a question. The maximum I can cut off the back of the car and move to the front is approximately 5/16". Anything more than that I start to pass the back of the wheel. I then move the 5/16" to the front to take advantage of the "Front End Extension" effect and the higher velocity. My ca...

Re: Help for a newbie

I agree, 3 wheels touching would be excellent. I'm trying to picture what this lady might be going through by what she originally said. If she lives in an apartment, has no tools, never used tools, is experiencing the 1st year in the pinewood derby, has no knowledge of how to build a car, then I fea...

Re: Help for a newbie

This has got to be an emergency! It's getting late. A few questions. Is there an experienced person in your Pack that can help you start to finish? When is your Derby? Is Graphite legal? Do you have access to a drill? A Drill Press? An accurate scale that will weigh in grams? I would forget the Cama...

Re: Checking run out on the wheels.

OK, Sporty Inc. LLC. How much you want for a set of wheels? I trust you. I'll send you a check. They have to look stock. I'm already working on next years car with Mr. Pope's guidance. Take your time. No rush. I've got a year.
Cheers

Re: 1st time trying to make a rail rider

Thanks for the info, Mr. Pope. I'm glad I don't have to race you. I think our rules (lousy and getting worse) are an attempt to make it more fair for a scout who has little or no help. This should be corrected in the Pack. Every year I offer to help anyone who requests it. I am not involved in scout...

Re: Neat trick with wood putty

You might like to try auto body filler popularly known as Bondo. This is great when working with scouts because it dries so fast. When it reaches its spongy stage you can cut it with a razor blade. When it's completely cured sanding then becomes minimal. You will probably have some "pinholes" so get...

Re: Checking run out on the wheels.

Would not the Wheel Balancer you buy on the internet work for this? I built a "Poor Man's" dial indicator to check the wheels as best I can. Even if I owned the best lathe in the world I probably couldn't get them as good as Hodges or Maximum Velocity gets them. Yep, I buy my wheels and axles for my...

Re: Rules say all 4 wheels must touch

pgosselin, If Doctor Jobe is correct, raising one wheel off the ground does not reduce friction. That's a Pinewood Derby Myth. Almost all the friction is between the axle/wheel hub assembly. The friction from the raised wheel is simply transferred to the other 3 axle/wheel hub assemblies. However, 2...

Re: What do you do after derby is over? Fake knives!

The Derby is never over for me. It is my year around hobby. I teach the Physics of the Pinewood Derby to Nursing Home and Assisted Living residents as we build cars and we then have a race after all our cars are built. We follow the rules of my District and use the BSA kit. I've built many tracks an...

Re: 1st time trying to make a rail rider

Very Good Question. It is one of those rules that can't be totally enforced. The inspectors are looking for very obvious violations, which the man was in my previous post. The information you have given me leads me to believe I can build a "legal" Rail Rider under our rules if I look through enough ...

Re: 1st time trying to make a rail rider

I'd like to share a story about axles and their preparation since the topic was brought up. Let me start by saying, Yes, I do prepare my axles and I am very meticulous about it. Two years ago I was working the repair table at our District races. A scout got caught with bent axles (a No-No for our Di...

Re: Local clubs and tracks

Good Morning, Noskills, I'm going to guess at a lot of things. If you're getting into this and you will be in it for quite sometime, this is what I would do. Buy a piece of 1/2" plywood and build yourself a 2 lane track. You can buy 1/4" x 1 1/2" pine lattice strip at many places. This will save you...
