First of all, there is hardly a reason to use /32nd’s in woodworking.
Basically, ignore them. I know I do!
I feel fairly comfortable with my 1″, 1/2″, 1/4″ markings.
But if you throw a 3/8″ or 7/16″ measurement in there I get nervous.
Let’s break down the ruler markings.
Great, easy peasy. We get those.
Next, we will look at the 1/8 of an inch. I have to think of it as the inch has now been broken into 8 equal sections. Count them up, you will see. (1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, 1 inch)
Notice, I didn’t mark it as 2/8 (which is the same as 1/4.)
Next, and don’t get all nervous. We will look at the 1/16th markings. Again, just think of it as the inch has been split into 16 equal pieces.
Same rule applies. 4/16 is the same as 1/4, so don’t make it more complicated than it needs to be.
When possible, use the more common term for your mark!
