In the first picture you will see this U channel I used that the coolant travels along. The key is to not have a great deal of pressure with coolant and chips, as in...There is only a small angle that the channel creates, enough for the coolant to flow at a good pace but not fall with gravity and chips like most conventional systems.
The drain is a center drain and has a pre-filter, again a simple humidifier pad is use on top of the drain hole and piece of meal stock on top to keep pressure so that it contacts all it's surface area. When the coolant gets through and travels down the channel, it encounter two more filters before falling into the oil funnel which has a screen, that catches any little chip that get through the end.
The coolant travels down a hose and spills on top of the container lid where gravity lets it fall through the cracks.
In the last picture, notice the hose and wet area?
