Hi everyone
Fancy something different?
It sounds fun and I reckon with so many inventive and handy members we could have a few entries. Here are the kart rules. Let me know what you think. It is held in September - too late to enter for this year but we could perhaps have a rally starting on the Thursday or earlier and help each other. Ideas welcome
Soap Box kart design
The design of the karts is up to the builders. Remember that the judges will be looking for style and originality. Builders should keep in mind that the Soap Box should be built with the intended driver in mind.
1. Soap Box karts are powered by gravity only – no engines or motors.
2. Karts can have one or two drivers.
3. The driver must sit in the kart, facing forward and control the kart using only hands and feet.
4. The kart must fit the driver. Drivers must be able to get in and out of the kart easily and operate steering and braking in the normal seated position without stretching or straining.
5. The centre of gravity, with the driver in place, should be as low as possible without violating the minimum road clearance (8cm) specification (including brake).
6. The kart must have four wheels; minimum diameter is 15cm. Wheels may not be made of wood.
7. Measures must be taken to prevent wheels from departing the kart when in use. Use cotter pins or other positive means to keep the wheels in place.
8. Fasteners used in the steering and brake systems must be prevented from loosening when in use by using lock nuts, cotter pins, wire tying or other means.
9. Maximum overall kart length, 280cm.
10. Maximum wheel base (distance between front & rear axles), 190cm.
11. Maximum kart body width, 150cm. Minimum kart body width, 50cm.
12. Maximum axle length, 140cm.
13. Minimum road clearance to any part of the kart, including fasteners, must be 8cm.
14. Minimize front and rear overhang.
15. All basic structure parts must be securely fastened to each other using bolts, screws or other suitable hardware. Plywood and solid wood are permitted structural materials. Particle or strand type board is not permitted for any structural part.
16. The basic structure is defined as the chassis on which the driver sits and to which the axles, steering and brake mechanisms, and body shell are attached.
17. The kart body or shell may form part of the basic structure. It must be made of rigid impact resistant material.
18. Back and forth movement of either front wheel shall be limited to 3cm. Stops must be installed to prevent over-steering. Steering movement must be smooth.
19. The kart must have a braking system capable of slowing the kart to a smooth, short and safe straight line stop without damaging the road surface or making contact with the tyres.
20. Cable links used in steering and brake systems must be secured and not slip under stress.
21. Adjusting hardware such as turnbuckles must be lock-wired in the final adjusting position.
22. We recommend that the drivers lower torso, legs and feet are within a body shell. The driver should not be able to contact the road surface or the wheels when seated in the normal operating position in the kart.
23. There shall be no exposed sharp edges or points.
24. Exposed edges that may be contacted by the driver shall be smooth. Protective cushioning material may also be fitted.
25. Build a stiff non-flexing basic structure. Try to keep karts light, but tough and strong. Do not add additional weight.
26. It is recommended to incorporate hand-holds for ease of handling.
27. It is vitally important that the kart can be driven repeatedly without steering and brake adjustments.
28. Test the steering and brake mechanisms for strength, repeatable and smooth operation.
29. Test the whole kart on a sloping surface. Make certain, through testing, that the intended drivers can safely operate the kart.
Please do not arrive at the Soap Box Derby with an untested kart or driver!
