Well GB I think we all overthink at times. So now lets think of grinding a lathe tool blank and and take a healthy grind till ya fingers get hot so dunk it in cup of water continue on, and then I have faced valves with nothing at all we are only facing not grinding an axe if its rusted or deep pits then in the chip barrel.there is a coolant nozzel but nothing else on the machine? I would show a pic but it says enter a url ? what ever that is so I can not but use to.
