The wheel-molding process isn’t perfect – but that’s no reason your wheels can’t be!
This simple tool makes it easy to create perfectly round wheels for your CO2 dragsters and other model cars. Place the wheel on the lathe and press the run button while moving the cutting tool back and forth across the wheel – adjust the lathe’s gauge to the tire as needed.
Requires a standard 120 V wall outlet. For use with standard-size dragster wheels (approximately 35 to 40 mm).
Fold it up and start racing within minutes!
The Fold & Race Ramp is designed to test and race Fold-N-Roll Racers, balloon cars, and other rolling models in your classroom. Economical, easy to store, and fun to use.
This ramp will last year after year! The sturdy Roll Test Ramp is made of coated metal and features side rails and a folding leg for convenient storage. The two lanes are separated with a solid line and allow side-by-side comparisons of two vehicles.
Use it to test the rolling friction of wheels and axles of metric dragsters and other rolling model vehicles. Measures 37-3/8" long x 9-1/2" tall.
Laden with smart features, the CJ600 Digital Scale combines precision weighing with compact, quality construction. The orange backlight and extra-large LED display make it easy to read.
With the CJ600, you can weigh up to 600 grams in three different units: grams (0.1 g), pounds and ounces (0.01 oz), and pennyweight (0.1 dwt). Includes tare and zero functions as well as a handy counting feature. Comes with a clear scale cover that doubles as a bowl to use on the scale.
Operates on three AAA batteries (included).
Versatile and small, this pocket scale is extra-sensitive like bigger and more expensive scales. Ideal for the lab or science classroom needing to weigh items for experiments and tests. Weighs up to 500 grams (18 ounces) in 0.1 gram (0.005 ounce) increments and has counting, tare, and display hold features. Automatic shut-off ensures long battery life. Uses an included 9 V battery.
The quick and convenient way to check dragsters for TSA specifications. Use this gauge for measuring minimum and maximum requirements for front and rear wheel widths and diameters; body length, width, and height; and screw eye and axle position.
To ensure that your students use the current specifications when designing dragsters, refer to the TSA Competitive Events CD (for details, see the TSA website).
Designed for use in the lab, classroom, or office, this electronic balance is the perfect weight measurement tool for your dragsters or weight-related competitions. It is easy to operate and features a two-button operation, a high-contrast LCD display, multiple weighing units, and four application modes. This balance measures to the nearest 0.1 gram, with a capacity up to 400 grams.
