Geez... when I was in 7th grade shop, we used a tool to dress the wheels on the 
grinders. That and attaching a grounding strap to your arm when you're 
polishing plastic on a buffing wheel are the only two things I remember about 
"shop". Oh, yeah, I remember watching the girls gym class in the summer, 
looking out the window too.  :-)

Aluminum is soft and what happens, over time, is that the small bits of 
aluminum build up in the open pores of the abrasive wheel and the 
forces involved will sometimes cause the wheel to crack and come apart 
- - and pieces of the wheel can go flying in many directions and you 
could be injured.  Definitely a no-no.  If you want to use a power saw, 
use a carbide tipped regular wood type blade, not the abrasive wheels 
that are for steel ONLY.
