I keep the buffer inside a big cardboard box when I load the wheels then pull it forward a bit to get enough light from above to use. The box has more grit in it then the wheels ! Then Apron, pull over nylon cargo pants, and I have to remember to change my glasses or I will wind up wiping the good ones with a gritty cloth which would be BAD ! Ill try shutting it on and off but that cant be good for the motor. My old bench grinder spins for a minute when you shut it off, the buffer is like my new Dremel which stops right away when you shut it off. Now I know why the guys say slower. 3450 is not bad for buffing but for loading the wheel with the coarser grits it is terrible.
