Design Drawings for CO2 Dragsters

“Look at other projects; talk to people. The way I learned a lot of things was by talking to people at the national level.”

– Ahmad Hares, formerly of Bradenton, FL


The durability of nickel-plated brass combines with the strength of fiberglass-reinforced plastic to create this light, yet nicely balanced, large 6" pencil compass. Designed especially for educational use, it will draw a circle up to 11-3/4" in diameter, and its built-in stop helps keep students from overextending the legs. Each compass comes packaged complete in a soft plastic sheath with a tube of lead.


Use to draw guidelines for easy lettering, 1/16" to 1-1/2" high.


Perfect for anyone new to drafting, this Beginner's Drafting Kit has everything you need to get started.


Highly versatile drafting aids with a raised inking edge and calibrations in both millimeters and inches. These calibrated curves make it easy to draw perfectly contoured curves and then measure the length of the created curve. The flexible construction enables you to shape it to any curve with a radius as small as 1". Specially designed core enables the curve to maintain the created shape. Great for drafting and creating curves on CO2 dragsters.

Designed with the user in mind, the fluorescent color of these triangles sets them apart from vellum and paper, making them easier to locate. Light reflects along the edges so lines are easier to draw. Made of 0.10" Grade A acrylic stock.
