2021 Race
9/5/21
Thank you everyone for making the 2021 derby a success. We had the biggest crowd we've ever had in PaysonRace results:
Colts
  1st Lilly Black
  2nd Ethan Fillmore
  3rd Josie Butler
Mustangs
  1st Parker Boyer
  2nd Amber KilmerStallions
  1st Alex Lockwood
We are building a new ramp. We can use donations of steel--stuff like expanded metal, square and rectangular tubing, angle, and round tubing. We could also use a dual axle trailer to build the whole thing on. We have a bunch of 2X3 rectangular tubing, but it's all welded up in a pallet for machine tools, so I'm not sure how much of it is usable.Contact me at FLeany (a) gmail dot com if you can help.
Also, I've posted some links to some cool old derby photos on the photo page. I'd stick a link here, but I'm too lazy--but no lazier than you are if you can't click on the link at the top of this page . . .
:o)
I have posted the notes from our post-race evaluation (we don't call it a post-mortem--bad luck in racing) here in MS Word (pre-Office 2007 disaster) format.The main complaint was that it was super disorganized. Next year you have to be registered two days before the race or you don't race. Let me put that a different way: YOU HAVE TO BE REGISTERED TWO DAYS BEFORE THE RACE OR YOU DON'T RACE.
We had no idea who or how many cars or racers we were going to have and were still putting together brackets ten minutes after the race was supposed to start. Two days before the race starts next year we will know all of the first heats for all of the divisions and have an idea of all of the possibilities as the brackets tighten.
Also, we're going to build a super-duper extra deluxe ramp for next year. Read the notes, if you want. Save me typing everything out twice.
Thank you to everyone who helped pull of this year's race. As Russ said, we passed probation. Please post your feedback on our FaceBook page. We'll have a meeting the 19th at 8:30 to consolidate all the ideas for improvement for next year.Chief among those improvements will be that all racers will have to be registered by the Monday before the race. Most of the delays last night could have been avoided had we come to the race with an accurate list of who was going to race.
We ended up with 17 racers in six different cars.

Please post your feedback and suggestions on our Facebook page. We are called Salem Derby.
Since we run the same cars in different classes, questions have come up about how to guarantee the ballast is correct for each race. We could run every car across the scales for every race. My brilliant son came up with a way to weigh the cars on the ramp. You just weigh them with a game scale held parallel to the ramp and trig out the corresponding mass.We will probably have all cars have an eye bolt set 12" high on the back of their car and have the game scales mounted 12" off the ramp. I have included a page in the spreadsheet for what the scale readings are that correspond to the car's mass based on ramp angle.
If you'd like you can make a little slide rule that shows the same thing by printing out this image on card stock. Cut on the solid lines, fold on the dashed ones. Wrap the outside around the inside then for a given angle of the ramp you can read directly the maximum the game scale can read for the car to be in compliance.
No charge.
The version in the word document is the final version. Main rule changes are:Rules Updated
- Registration fee is $10 per driver. Racers must show proof of having paid before they can race. Wheels are no longer subsidized by the City. Each racer buys his own from Harbor Freight.
- Colt Class racers will be started below the ramp to reduce their top speed.
- All vehicles must be equipped with brakes that contact the rear tires. Brakes must be able to completely stop the tire. The driver must be able to steer while braking.
- Pivot axle steering must have limiters that prevent the car from turning a radius tighter than 15 feet. Careful consideration should be given to the steering ratio (angle of steering wheel turn to angle of front wheel pivot) to ensure that the steering is not too sensitive.
- Maximum height of the seating surface is 16" above the road surface.
- The preliminary inspection has been moved up to 1-1/2 weeks before the race to allow more time to make changes. (6:00 pm Friday, July 30, 2010, in the parking lot by the pond)
- Maximum weights have been bumped up
I've modified the rules and posted the latest. These may change pending a meeting of the race committe this week. But they're close.Derby Back OnThe weight limits are increased slightly. We now require brakes that stop the back tires (no more road drag devices). The tightness of the steering radius is limited and the inspection date is moved forward to a couple of weeks before the race to ensure that everyone has time to make the cars safe. We will measure both braking and steering at the inspection and if you don't pass you don't race. That way we don't give anyone an excuse to cancel our fannies again.
We will fully line both sides of the road this year with straw bales. We may even put a line of bales down the center. If you're curious about why the new emphasis on safety search "Soap Box Derby Crash" on YouTube.
We've added verbiage to the effect that you should keep the center of mass as low as possible, but we probably won't place a measurable requirement on that (because I'm too cotton-picking busy to build the device).
Another new thing this year is that we will be enforcing the entry fee. In the past we figured it was the city's job, and I suspect some people figured that the chumps who paid the fee could supply the money for the prizes. This year if you don't have a receipt from the city you don't race.
The city has agreed to resume the Gravity Gran Prix. Thanks to everyone who worked on petitions and presenting and keeping the heat on.I'll post new rules and guidelines early next spring. In the meantime, don't turn that soap box racer into firewood.
