Don't mean to change the subject here but I have always wondered why the spacing on factory fan blades is not even.

OK, so who taught Charlie how to use a ruler? Figuring out that measurement involves higher math!

LOL...Bigchevydaddy...The ruler was to show distance from bolt centers.

i think air much like water, can cavitate if the blades were all spaced the same, i think the odd spaced blades move more air??
