[TheForge] OT -12v motors

[Jerry Frost]

Hmmm, your last post and this one raise a couple questions in my mind. #1 
Are you really teaching your students to be slow learners?
#2. I agree, a butter fingered person carrying an anvil in the shop may well 
be a contender for most dangerous.

More seriousness now. Don't push into the wire wheel or buff unless you have 
to to get to the inside of a feature. Wire brushes and buffs work best at 
the ends of bristles, it's where the fibers carrying compound of wires don't 
slide across the project. If you push hard enough to bend the wires, they 
lay flat and don't cut, same for a buff. A heavy touch will also load the 
grit in a stone wheel reducing it's tooth while rolling the edges of the 
stock.

Guards on rotating machinery are good ideas but I've had things come through 
some guards and the ones nothing can get out of make it really hard to get 
things in through meaning you are working at BAD angles of attack. Learning 
to work out of the potential ballistic tragectory(sp?) is your best bet. As 
an added safety measure, especially when others are in the same area is to 
put something behind you like a locker to act as a scatter shield.
