Concept Sketch Dimensioned Drawing. Make sure the corners are rounded. Try to keep each side symmetrical. This will help maintain good balance. Paint that does work is all purpose spray paint or acrylic. Be sure and apply a primer coat first.

You can use shellac or clear coats to give your carC a shine. The straw should not stick out from the sides of your car. Now insert the straws in the axle holes. Axle hole should be 4mm or 0. Make sure there is not a lot of friction. The wheels should move freely. They need to be located on the centerline of the bottom of your car and on the lowest points near the front and the back of your car.

Twist in the screw eyes then place your car on the desktop again to see if they rub against the top. Twist them further in if they do. All four wheels should be touching your table.

Lubricants help to reduce the friction on the axles. Rub pencil lead graphite on your axles to help them turn with less friction. Sand down any burrs on the surface of your plastic wheels. Do not use liquid lubricant. The criteria listed below must be followed closely.

Cars that are not built within these measurements may not be permitted to race:. Now is the time to get some of those race-car design ideas — undoubtedly floating around in your head — on paper. The best way to start is with concept sketches, also known as thumbnail sketches. Thumbnails are small, quick sketches used by engineers and designers to rapidly communicate ideas. They should not be detailed or even carefully done.

Be sure to experiment with different ideas and be as creative as possible. On a clean sheet of paper, sketch your favourite design from the thumbnail sketches on a larger scale with more detail.

Draw the top and side views. Make light projection lines from one view to the other to help you locate axle holes and other features of your design. Show the location of hidden details such as the cartridge hole by using dashed lines. Check the specification. Look at your design sketch to see how each spec applies to your design. You may find it necessary to take notes or even change your design. The working drawing is a precise, scale drawing that describes your car and its features.

Working drawings should have top and side, or profile, views. An accurate working drawing is important for two reasons: 1 A copy of the working drawing serves as a template for rough-cutting your car blank. It could be part of your grade or even be scored for competition points ask your teacher about this. Be sure to refer to the specifications sheet as you go.

Create axle holes of 4mm in diameter 0. If your design calls for a hollowed-out body, a high-speed rotary multi-tool works. Try not to rely on power tools to correct a poor design. As in the fine shaping stage, extra patience and effort put into the finishing stage can pay big dividends. Make up a handle and hanger. Slightly sand off the edges at one end and drill a hole in the other. Insert the handle into the power plant housing of the car body so that the timber jams slightly against the sides of the power plant hole.

Enough to hold it on the handle when it is hanging down. This makes a very convenient handle for turning the body to paint it from all angles and you can hang it from a nail over a drip container while the paint dries. Apply undercoat and sand between coats. You can dip the car body into a deep tall vessel, such as an old vase, filled with the paint and let it hang to dry.

A 3-D model is literally developed in minutes! The simplicity of the modeling process puts focus where it belongs - learning the critically important science, technology, engineering and math STEM that lives just below the surface. And it's completely web-based Then, "connecting the virtual to the physical", students can print custom templates to build their actual racers.

It's not magic or luck In this section, your students will find all the theory they need, as well as plenty of activities and tools to put it to action. Plenty of tutorials will ensure that they are well prepared for the remaining sections. Engineers know their science -- that's for sure.

But they also have great tools to help them visualize their design in 3D. In this section, your students will use our custom, built-in CAD system to create 3D models on screen and quickly choose between various axles, bearings, and wheels.

In this section, your students work with a number of built-in tools to see how well their design stands up to the scientific principles presented in the Research section. This stuff is really neat, but it won't make much sense if they haven't completed their Research! Virtual Race. Ready for some fun?
