Re: Weighted Wheels

"Wheel Weights" made for Pinewood Derby don't attach to the wheels. They attach to the side of the body and take up the space in the void of the wheel, without actually touching any of the moving surfaces. Thus you get the advantageous weight location, and the aero advantage from blocking air inside...

Re: Interesting Race-Girl Scouts-Longish story. Laser Gate Issues?

Race#67 I feel that the laser gate isn't a true time due to that the first car that breaks the beam starts the time. I feel that once's the car's are release from the gate the timer is started. We use GPRM and we throw out the worst heat time. Some people like to use the laser gate and some don't. ...

Re: Interesting Race-Girl Scouts-Longish story. Laser Gate Issues?

Wow, not much time at the moment, so I can't think too hard on it, but those time variations seem WAY out of spec from what I'd expect. In pinewood derby, a few hundredths of a second is enough to put you a car length in front of somebody else. We're seeing variations of 3-tenths of a second. Someth...

Re: 2017 Ford Fast Track Races

Did I mention how efficient Randy Lisano is? He has already posted pictures of all the beautiful cars. What a guy. Ford, the Girl Scouts of America, and so many others owe him so much. Thanks Randy. It was great to meet you. Very cool. Y'all have been corresponding digitally for a long time, it's c...

Re: Auto-start gate for Freedom Track

I've had a couple of different solenoid gate setups on my Freedom track. The DIY one stopped working reliably after awhile. I didn't want to muck with the circuit, so I ended up switching to a commercial solution. http://derbytalk.com/viewtopic.php?f=15&t=7948&start=15#p77292 http://derbytalk.com/v...

Auto-start gate for Freedom Track

Our Pack has a 4-lane Microwizard Aluminum track. One thing that's always been a hassle is the start gate, as it tends to get wonky during races, and there are issues with it not contacting the timer switch properly when closed, that requires last minute bending of little metal switch levers. Ideall...

Whoo! Is that Optimus Prime?

Concur with Speedster and BR. Run it, but take yourself out of the winners' circle.

Re: Ford Fast Track Racers - Phoenix Event

I stumbled upon this Phoenix event in a web search. This is not part of 8 city race series that Ford is doing but the girls will be building and racing cars. Sounds like a pretty cool event. http://www.girlscoutsaz.org/content/girlscoutsaz/en/sf-events-repository/2017/ford-fast-track-racers---part-...

Re: 2017 Ford Fast Track Races

Would be nice if they expanded this to a Nation-wide thing on a local level with open participation (races hosted at car dealerships?)...and then Ford could host a big National championship or something. :) Also, yeah, those rules...holding my nose here. Here's to hoping they actually run the final ...

Re: Getting more Scout Races to support oil as a legal lubricant

I don't know about "most places", but we've never restricted lubricants, as long as it isn't applied excessively so that it causes a mess. But about 10 years ago, we switched from providing graphite at our workshops to providing Krytox at our workshops. But the motivation was more to eliminate the ...

Re: Getting more Scout Races to support oil as a legal lubricant

None of the 6 Districts in our Erie Council allow oil. I'm going to guess at scout level most people agree there is no reason for oil. Graphite is cheap. A bottle of Krytox from Maximum Velocity, plus shipping, is $23.70. Oil cars require grooved axles so rules would need to be changed and most peo...

Getting more Scout Races to support oil as a legal lubricant

Hey folks, So I'm interested to know: Those of you who run races at the Pack/District/Council level: How much resistance do you see in recent years towards the adoption of rules that permit oil as a legal lubricant? Is there momentum building to make oil more acceptable, or does it seem that "only g...

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...
