Re: weight placement

The test was performed on a 32 foot aluminum freedom track. I doubt the the length of track would make any difference, but that is just speculation.

Re: Do you sell product at workshops?

We allow the PineCar Zinc plates to be screwed to the bottom, even though it drags on the car inspection gauge. But I know that the cars will be fine on our track. Typically guide rails are 1/4 of an inch, so there is plenty of room.

Re: New Pinewood Derby Products from Maximum Velocity - 11/1

The width part of the wheel gauge is to ensure that the wheel is not narrowed too much. So a raw wheel will not fit in the gauge (thus it passes). If you remove .020 inches (or less on many wheels), then the wheel will fit in the .360 gauge. So if you pack establishes a .360 minimum width, then the ...

Re: 2008 Special Edition Kits

The wheels were improved in 2009, so if you use them, make sure that everyone uses the same thing. The 2008 wheels were heavier and not as accurate as the 2009 wheels.

Re: Pinecar one piece axles

PineCar wheels are the heaviest wheels on the market, so they tend to be the slowest. If at all possible, get some US-made BSA wheels. You will be much better off.

Re: Pro Stainless Steel Axles from Maximum Velocity

Speedster - You can use one coupon per order, so yes, you can get a discount on only one set at a time. TXDerbyDad - The axles are attracted to a magnet. The points are round, not chisel points like the official nail. So if your rules only allow BSA nails, you can tell the difference by the point. A...

Re: Pins and needles

Maybe I missed this in all the discussion, but the fundamental difference between the Pro-Body Jig and the Block, is that the Pro-Body Jig can be used with a hand drill or a drill press, while the Block requires a drill press. So if you don't have a drill press, you use the Pro-Body Jig.

Re: Generally speaking: grooved or not for oil? Graphite?

As Stan points out, the test were done with a weighted wheel spin jig, so the test simulates a wheel under real conditions. http://www.maximum-velocity.com/nl/v8_i6_figure1.jpg You can read the full article here: http://www.maximum-velocity.com/pinewood_derby_times_v8_i6.htm#feature" target="_blank ...

Turcite is a self-lubricating, engineered thermoplastic. It comes in either red or turquoise. We purchased a small quantity of these plastics and h...
