Since we're on the topic of grammer, i have been reading some build threads and noticed something that is often overlooked. when typing/writing quantities and sizes together, the best way to write this is if you use words for quantities and numbers for sizes. For example:
I unbolted the four 1/2 in bolts.
I unbolted the 4 1/2in bolts.

the first sentence says a quantity of four and a size of one half while the latter can be seen as a size of four and one half.

Another notation is:
I unbolted the four(4) 1/2in bolts

its not necessary but it helps with clarification. Just throwing it out there.
