good pic,
it does bring to light something else, at least for me. and that is this:
though exaggerated, it is easy to see that timed cuts take formerly alligned brushes and, basically, misalign them.
after the many claims i've read about aligning the brushes and the profound effects that this has on overall power #'s, i'm wondering how affective this method is. i do undertand the inverse proportionality between torque and rpm when timing is changed, but wouldn't overall power #'s decrease from poor alignment? or does advancing the timing alter the amount of current that the motor will draw, in turn, making a generally more aggressive motor?
uh oh.
keep in mind that realigning the hoods after the cut is made will negate any timing effect that the cut was intended to accomplish.
