ok got you,
I have a splash tray on wheels with a square cut out it so that it can go around the mill table column and get pushed right back,
The enclosure is tapered in at the bottom so it sits quite far inside the splash tray, it has a rubber apron attached to it at the bottom that touches the inside bottom of the
splash tray , the reason for the rubber is when the coolant runs down the enclosure and splashes on to the bottom of the splash tray it can not splash back out on to the floor.
The coolant once inside the splash tray runs down in to the mill sump.
