I have to admit I don’t always wear proper eye protection when milling or turning because I wear glasses but ALWAYS a face mask when grinding. Yesterday I had to grind away a bit of concrete in a basement project and (although I might have caused it) my 7” concrete side grinder disk blew up at 8000 rpm. It broke the clear plastic of the face shield and permanently deformed the hard plastic frame enough to put a 1.5”x.5” laceration into my forehead above one eye. Lots of blood, like any head wound, and I’m now sporting 5 blue stitches (my favourite colour). No muscle damage so I can still frown . To this point I had always looked at a face shield as a means to keep grit or small particles out of my eyes but had not considered flying chunks of this mass. I can’t think of what mistake I might have made but I do know this: I’m a very lucky guy. Let the flaming begin.
Cheers, al.
