Thanks to fred in the ToolGuyd forum, we learned that Woodpeckers is cranking out yet another one-time tool. This time they are manufacturing 6 different 45-90 stainless steel triangles for marking angles.
Right away, you’ll notice that instead of the small holes they usually have in their measuring tools, there are diamonds. Woodpeckers touts these diamond-shaped holes in the triangle as a better way to precisely mark your angle, and that they virtually eliminate parallax problems.
Woodpeckers has mentioned eliminating measurement parallax before with some of their other tools, but what do they mean by parallax?
Parallax basically means that you see things differently depending on what angle you look at them. Measurement parallax results from trying to use your measuring device while looking at it from an angle that isn’t exactly perpendicular.
With parallax, your pencil might look to be perfectly lined up with a marking, but in reality it might be a little off.
By tracing one half of the diamond with your pencil, you get a chevron with the tip being the correct angle measurement, just like how your dad taught you how to make marks with a tape measure.
There are two ways to mark angles with these triangles.
Woodpeckers has engraved a scale along the hypotenuse of each triangle, in 1° increments. To use this scale, line up the angle with the outside edge of the square corner. You know you’re using the triangle correctly when the 0° angle is resting along your reference edge.
The second scale consists of the aforementioned parallax-eliminating laser-cut diamond cutouts. The larger two triangles has three arcs of diamond-shaped cutouts, giving you a full range of angles in 1° increments. The smaller triangle only has the common angles of 0°, 22.5°, 30°, 45°, 60°, 67½° and 90°.
To use this second scale, you line up the angle with the inside corners of the square corner. Again, you know you’re using the triangle correctly when the 0° mark is aligned with your reference edge. The 0° cutouts help with alignment, assuming your workpiece has a straight-cut edge.
Woodpeckers also laser engraved both short edges of the triangles with either 1/16″ or 1 mm scales.
Each triangle is made from 16 ga stainless spring steel and has with a non-glare satin finish. Both sides are fully engraved with all the same markings.
Sizes and Prices
- 4-inch or 100 mm for $30

The triangles are shipped in a wall-mountable MDF case.
As these are Woodpeckers One Time Tools, there is a short preorder window, ending Monday, May 16th, 2016. Woodpeckers expects for these 45-90 triangles to ship around September 2016.
Right now you can preorder from Woodpeckers. We expect that you will also be able to preorder them from Woodpeckers partners starting soon.
