[TheForge] OT -12v motors

[Jerry Frost]

That's true indeed Grover but screwing up work faster means you learn faster 
so it's a trade off.

Andy has a solid safety point; faster means more damage if the work gets 
away from you. SO stay out of the plane of rotation. Make it a matter of 
reflex when operating wire wheels, buffs and belt grinders even wheel 
grinders. If you just never stand in the plane of rotaion you never have to 
remember which when it's okay or which tool might get you a new piercing in 
a bad place.
