I am wondering if anyone has done any modification in terms of adding water coolant or compress air to their setup?
Other member in the forum suggested adding WD40 when milling aluminum, which lead me to think there gotta be a more automated way to inject coolant or compress air ( i suppose this is a seperate discussion ) to the mill area.
I think compress air set up would be nice too.
So what would be the best setup for shapeoko, with a DW660 spindle

Any thoughts?
Cheers
