6000 rpm
I was hanging around in the garage with my dad one weekend. I was maybe 6 or 7 and loved to put on his old iron worker hard hat, goggles, respirator, welding gauntlets, etc. He used to do all kind of wood working projects to make extra money. He was using a billion year old Sears router, and right as I walked up in my full Darth Vader safety outfit, the cooling fan/fins let go and it peppered me with a handful of sharp nickle sized shards of metal in the face and head. Thanks to an over active imagination, I didn't have a scratch on me
