Re: 2017 Northern Star Council race is OPEN TO ALL!!

That's pretty awesome. If only I was within spitting distance of the NSC.

Re: Opinions of the group

An Extended wheelbase car is a speed advantage. Recommended amounts of weight behind the rear axle slot changes. They're easier to tune. Why would anyone want to give a skilled builder any advantage? Some folks with long tracks have shortened their tracks so cars don't get spread out so much. Allow...

Re: Opinions of the group

If you don't have the means to drill a hole or cut a slot, I would argue that you're going to have a hard time with the other aspects of building a Pinewood Derby car as well. At our workshops, we have a drill press and an axle jig. If somebody wants an extended wheelbase, we can do it for them righ...

Re: ThunderPeaks Pinewood Derby Car Photos

Very nice presentation, as always! Question, though: Do you think there's any information risk with putting the boys' full names on a publicly available site?

Re: Opinions of the group

I fail to see how allowing oil and an extended wheelbase is an attempt to create a "level field" for the scouts. Each of those helps the scout following science. Krytox oil is expensive and Dad's going to buy it. The scout following science is probably going to have a car that looks like ...

Re: Wheel Test Question

Thanks for the reply. That is an interesting point about the weight. And that the outside may have been perfect but we have no idea to how well it is in relation to the bore. The concentricity gauge is of interest to me. I had not trusted myself in using home tools to true the wheel. The "Pro&...

Re: Wheel Test Question

I don't know that free-rolling the wheel offers much in the way of useful diagnosis for how the wheel performs on the track. Remember that for concentricity to matter, you need the wheel's tread to be machined true to the bore. If the outside is perfectly round, but the wheel is off center, it will ...

Re: GPRM: Strategy for calculating top groups?

With any version of GPRM, there is the ability to export a report as a CSV file. You would still have some data massaging to do for your specific requirements. Sent from my SM-T550 using Tapatalk Huhn, I'll have to look again. It didn't offer a CSV option from my recollection...just an Excel format...

GPRM: Strategy for calculating top groups?

So we recently had our District Pinewood Derby. One of the awards that we have is a "District Cup" in which the top performing Pack gets their name engraved onto a large cup. The way that we calculate scores for the District Cup is as follows: Each Pack can send one car in each of the foll...

Re: Opinions of the group

Many of the issues raised here are why I'm keeping the job of District Pinewood Derby co-chair, even though my son has now been in a Troop for over a year. My son's Tiger year, I witnessed a number of "lively dialogues" regarding parental interpretation of ambiguous rules at the District ...

Re: Mid America Pinewood Derby 2017

I will be sending at least one car in to the Pro Basics division.

My kids' cars this year are not fit for the Scout races (heavy wheels, oil lubed), but since we skipped fenders this year, maybe I'll send them to the Basics division as well.

Re: Want to take it to the next level

I've never heard of anybody having success using wax on the axles. If you try it, I am interested in hearing about it!

For buffing, definitely use the pipe cleaner.

Re: Want to take it to the next level

Whoda, lately I've been removing the casting marks on the shaft with the Dremel and a very thin cutting disc. I take the marks down below the level of the shaft. After that I'm not concerned the position of the axle to the bore. BB, I do not wet the shaft. Put Novus 2 on the shaft and also some in ...

Re: Want to take it to the next level

I don't think I'll ever bother with Q-tip stems again, since trying the Tamiya 87106 swabs. No more worry of destroyed bores.

That's interesting to me that you don't do any sanding on your axles, Speedster. How do they come out looking when you're done?
