I worked on a site with two carpenters once, and one would measure and the other cut. One guy would call out "inch and a quarter strong" or " inch and a quarter weak" etc. Meaning 1 inch and 3/8 or one inch and 1/8. Perfect cuts every time.

Isn't strong or weak mean where the cut needs to be on the line? Since the blade is usually 1/8", weak means that the cut is made before the line, removing the thickness of the blade on the measurement (1 1/2" becomes 1 3/8") and strong means that the cut is made after the line, leaving the actual measurement. This is how I was thought, but I am not in the construction industry.

Depends on the crews tolerances? I've used + or - to refer to 16ths and only call out 1/8ths. 1 1/2" would be "One and four" 1 7/16ths would be "One and three plus"

In old timey boat building they denoted feet°inches°eighths°plus so 58 5/16ths would get written as 4°10°2+
