This simple jig makes laying out circles a breeze. Drill a 1/8-in. hole through every inch mark on a ruler or yard-stick. To draw a circle, place a pin through the number “1” into the center of your board. Add 1 in. to the radius of the circle you wish to draw, and insert a pencil into this number. Using the pin as a pivot, rotate the pencil to mark the circle. — Edwin Constantino. How to Cut Curves in Wood
How do you divide 11-3/8-in. (or any other mathematically difficult number) into equal parts without dividing fractions? Simple. Angle your tape across the workpiece until it reads an easily-divisible dimension and make your marks with the tape angled. For example, say you want to divide an 11-3/8-in. board into three equal parts. Angle the tape until it reads 12-in., and then make marks at “4” and “8”. Plus: More measuring tips and tricks.
I know this seems really simple and you may already know how to read a tape measure so just hear me out on this one! Often times with woodworking you need to make exact measurements and cuts and it’s rarely pretty even numbers like 15 inches or 15 1/2 inches. It’s usually like 15 5/8 inches or 15 9/16 inches. So, really knowing how to read a tape measure in its entirety is important. And I’ve created a quick post on how to read a tape measure the easy way along with a helpful free printable.
