Re: wheel wax

I've heard of the MaxPro but never looked into it. So you DO NOT polish it with a clean pipe cleaner? You still want to do all proper bore polishing before you use the Max-Pro. I usually polish with Novus #2, using either a pipe cleaner or a tamiya swab (or both). Then I clean it with Blue Dawn and...

Re: wheel wax

For graphite, I don't know that a wheel wax is terribly important. If you're using graphite, I would just burnish it into the bores with a polished metal rod and leave it at that. For oil, you want some kind of oil-phobic coating on the bores (as I'm sure you know), but I've never heard of anybody h...

Re: MaxV wheels and oil

A bottle will go a long way with you or I applying it. I won't have total control over this as I'll have to have helpers working with the kids. We'll let kids put the oil on with the steel tipped Ny-Oil and I'm sure it will get over-applied in most cases. I'm kind of planning this event like you wo...

Re: MaxV wheels and oil

I'm putting together supplies for our first, church sponsored derby event. I'm using the Ny-Oil II because it's cheap in the 2 oz bottles compared to the common 5ml bottles or 1 dram bottles of other lubes. The church will be providing all the supplies and we've prohibited graphite just to keep thi...

Re: MaxV wheels and oil

I thought Ny-Oil had fallen out of use, in favor of Krytox? Is there a particular reason you want some?

Assuming you find some, I imagine it would work fine with the Max-V wheels and axles.

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 a Hershey ...

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" mand...

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 ...
