I have put on this event for the last two years in my district. The
boys LOVE it. Just run it like it says in the book and all goes well.
Look in the Leader How-To book for how to setup the race and a
design. Also the car design is in the Bear book. There is a
disagreement in the books about wheel sizes. I allowed the max. size
to be 12". The wheel barrow wheels made out of metal, with the
center on a bearing works the best. Plastic wheels are not very good
and tend to slow the car down a lot.
I tried to build the ramp like it shows in the book, but not being a
carpenter, I opted for another design in the starting gate. I got two
pieces of angle iron to go over the wheels. The angle iron was
secured to the ramp with chain. Then a rope attatched to the angle
iron. Then just pull on the rope and away they go. This worked on
some cars but not others. (That is because I allowed the boys to
build the car however they wanted as long as the deminsions for
wheel base, width, wheel size, and basic premiss on how to build the
car where followed. No extra weight was allowed.) So if you build it
like the book or some starting mechanism under the car, it will work
better. I am planning on rebuilding the starting ramp for this years
Also make sure the boys get those steering blocks in place AS SHOWN!
In this last race, two cars had the blocks to far (about and inch
instead of half inch) from the center 2x4 and lost control. They did
fast 90's. One kid tried to bail out of the car, but the seat belt
held on. He finish being dragged by the car. He was more scared than
hurt. The other rode it out and the parents stopped him before he hit
the street curb.
