Pat,

I, too, use 1/8's for calling out cuts with helpers. It has

sound levels on a construction site. ...


This was a common practice among molding, dado and plough plane
makers. A #4 dado would be 1/2" wide, for example.

I'm not clear on why it became customary in school to always
reduce fractions (is 'reduce' the right term?)

Using 1/16ths is still common for auger bits. I think they teach
"least common denominators" just to make the concept more intuitive
for kids. 375/1000 doesn't just jump right out at you as a
recognizable fraction.
