Re: Building a 100 Foot Track
I would use the PVC planking for the same reasons you identified. There was a 300+ foot track built near where I live a few years ago. It was built on a hill and used the terrain for the slope of the track. About 100' of the track was slope and the remainder was flat. The major problem with this tra...

Re: post race advice for next year
The kit they gave us was from maximum velocity in a ziplok bag so they bought in bulk. I found out that they gave everyone speed axles because I think there are alot of single moms in our pack and wanted to help keep things even as possible. Wheels were also from maximum velocity with mold numbers ...

Re: A nose-cone for a tube of pennies?
The tip of a party hat would be a fairly inexpensive option. Another option would be a nose cone from a model rocket. I know Estes sells replacement nose cone kits for $5-$10. You might be able to find some at a nearby hobby shop. You might even be able to find one that the pennies will fit inside s...

Re: Setting up my Test Track
The finish line of a BestTrack has several holes for timers. It could be that you are not using the same holes as other BestTracks. I don't think that would account for 0.17 seconds, but it could be a contributing factor. I suggest using a stopwatch or stopwatch app to do an independent assessment o...

Re: Approx. how much time do you spend on the build of a car
I spend about 30 minutes on body prep, which includes drilling axle holes and cutting, routing, sawing, chiseling, and/or dremeling weight locations (plus marking the block for these steps). Another 30-45 minutes for wheels and axles (including lubrication). Shaping the car can take between 30 secon...

Re: Drill Press vs. Dremel for axle polishing?
Is there any school of thought on which is better? Or rather the benefits / drawbacks of higher RPM? I have both a drill press and dremel tool and have used both in axle work. When working with coarser grits of sandpaper or a file you can inadvertantly reduce axle diameter in a hurry if the RPMs ar...

Re: 1st year with software.....HELP QUICK - Race tomorrow
The boys (and parents) have always been able to see who is in first place at the half way (each car having raced twice). We always participate in districts, so the boys start getting pumped at that point. If using GPRM one possible solution would be to set how the race is scored to only the fastest...

Re: Quick Start Front
That video was mesmerizing. In addition to the intent of the video, I found the movement of the springs fascinating. I guess it doesn't take much to entertain me.

Re: Reduced price on BSA Wheels and Axles?
I know that $1.99 has been the price for the tubes of wheels and axles, including colored wheels, at my local Scout Shop for the last 4+ years, if not longer.

Re: Need room layout advice
...my concern is that if the cars are stored up on the stage, they're unavailable for viewing by the audience. I suggest you determine what the audience will want to be viewing during different parts of the event. I expect that during the race the audience will be more interested in what's going on...

Re: tight grain or wide grain block
A block with grain close together (tight grain) will weigh more than a block with the grain farther apart. Sounds plausible, yet I was unable to affirm a definite correlation between block weight and grain density. Perhaps others have better data ? I think the phrase "will weigh more" was...

Re: tight grain or wide grain block
Thanks. Not sure I've ever seen a block with the grain running vertical. I've only seen ones with grain running front to rear. Is that what you mean? I'm talking about the end grain - what you see when you look at either the front or back of the block. This post has a picture of some blocks with ve...

Re: tight grain or wide grain block
A block with grain close together (tight grain) will weigh more than a block with the grain farther apart. The growth rings are harder than the wood between the rings. A block with grain farther apart (loose grain) will weigh less than a tight-grained block. It will also be much easier to drill, cut...

Re: Performance Tracking Software
I think that perhaps the fenders could be expanded slightly. The yes/no option is good, but there may be value in differentiating between front, rear, and full fenders. Maybe a field for fender type (none, front, rear, front+rear, full) or simply a field for fender description.
