LAB/SCHOOL

Our each is a package of (2) steel tech rulers. One is 6” x 1/32” for the first 2-1/2” then 1/64” for the next 1/2” then 1/16” for the last 3”. The other is 150mm x 0.5mm. Both have sliding markers/pocket clips, and both have mm:inch tables on the reverse side. You’ll need excellent eyesight.

It’s a cornucopia of stencils. All shapes, no alphabets. You’ll get a profusion of (8) clear acrylic stencil sheets, including: a raft of ovals; a preponderance of squares; a farrago of circles, hexagons, pentagons and triangles; a collection of a bunch of shapes, including trapezoids; a roomful of interior design shapes; a melange of electronic symbols; and an assortment we can’t altogether identify, but might be for printed circuit design. All have mm rules along at least one edge.

No, these scales won’t tell you how much weight you’ve lost (you’re so disciplined!), but they will help you design something super-technical. Know why? ’Cause they’re architect’s and engineer’s scale rulers, from Helix, both (3)-sided in silver aluminum with color-coded sides. You pick: the architect’s with separate scales for 3", 1-1/2", 1", 3/4", 3/8", 3/16", 3/32" 1/2", 1/4" and 1/8" per foot, as well as a 12" ruler in 1/16" increments, all in U.S. standard; or the engineer’s, with 12", 1/10", 1/20", 1/30", 1/40", 1/50", 1/60" scales.

Says so right on the packaging. Measures (pun intended) 18” long x 1-1/2” wide. Has 1/32” increments for the first inch, then 1/16” on one edge and 0-45cm in 1mm increments on the other. Made in England of blue-tinted translucent plastic. (There is no legal penalty for using it at home or in a school.)

Geometry teacher alert. These 6" plastic protractors have a 6" x 1/16" ruler on the bottom, and measure 0-180 degrees in one-degree increments on the outer arc and 10-170 degrees and 10cm ruler on the inner side. You’ll get a quartet of them in assorted colors, including clear and translucent red and blue.
