Rotation pivots correct sometimes else swirls around

When I rotate an object, it pivots exactly where I set the protractor.
BUT sometimes, I can do the exact same steps, but that other object starts and ends correctly, but the path the object takes wanders all over, as seen during animation.
What am I doing wrong ?
Position -1 is start and -3 is end. Position -2 is normal for Blade7, but out of wack for Blade2
Blade7 animates normally. Blade2 wonders all over in the middle of the animation.

Normal:
Blade7_1
Blade7_2
Blade7_3

Abnormal:
Blade2_1
Blade2_2
Blade2_3

Problem solved by moving the component (group) axes directly over the pivot point.
