You Can Make

Here are some proven jigs and tools that help you

to keep things square. Story by Charles Mak.

any woodworkers check for square with a try square
Mor a measuring tape (photo 1). I use them too,

but only when they are the right squaring tools to use.
However squares and measuring tapes used as a squaring
device have some limitations.

While a try square is good for checking small frames or
drawers, it is not reliable for checking squareness of large
areas. When a large piece is assembled, the clamps exert
force to close up the joints that can also, unfortunately,
bend the assembly. A tape measure would be a better

choice to use in large openings, but it has its share of
weaknesses and imprecision.

For example, tape sag can affect the accuracy of the

diagonal readings. And then there are the clamps that get 2
in the way... Lastly, odd diagonal measurements are hard to
1. Pinch rods and diagonal beams complement squares and
remember and compare, and that’s why, if I do use a tape, tapes for checking squareness.
I prefer one that allows me to mark the blade surface with
2. When measuring diagonals with a tape, the author uses
a pencil (photo 2) one that allows him to mark the blade like a story stick.
