    Not so effective in milling machines or lathes running steel, better in non-ferrous or plastics, but weirs are used exactly this way in coolant tanks, especially big rotary Blanchard and reciprocal grinders. Typically there are 3 'locks', flat panels stepped in height; some use one drawing from below against flotsam debris.
    A dream come true for every new shop-hand. . .

    Man did I hate cleaning coolant tanks when I was running grinders... Especially on the machines that used oil rather than a water based coolant. I always took a change of clothes on those days.

    Learned as much machining possible, as quickly possible for same reason. First shop had big Blanchards and Thompsons; had to be 50 gallons plus. Water soluble fluid was mixed by a venturi drawing from barrel of concentrate. Not high on list of enjoyable tasks. Rotary grinders were used prepping compression molds; big surface area, always both sides, very flat but not much concern about specific thickness. Lots of goo in the tank.
