Tips on cutting aluminum sheeting.

I have a buddy that got his hand caught in a milling machine while boring holes in aluminum molds he was making.

He swept some bits away with his hand and got too close to the cutter blade and it grabbed his leather glove and sucked his hand right in for a ride, was only in there for an instant but not before it ripped a tendon from between his thumb and pointer finger and mangled what another doctor had already repaired with metal rods and screws from a previous gun shot wound from a .32 hollow point.

I keep him away from my power tools as he has a propensity for pushing the envelope.
