For engineering students
Made for the bench
Drafting tools, gauges, working gear models and bench helpers. Turn the Geneva drive by hand before the exam asks you to draw it.
01
Mechanisms that move
Every gear set and linkage is a working model. Turn it, watch the ratio, and the lecture slide finally makes sense.
02
Tools for the drawing board
Set squares, protractors and templates for sketching and drafting. They are printed plastic, so check anything critical against a steel rule.
03
Priced by weight
The price follows the plastic a model actually uses, so a small tool is a small price.
