I haven't made one of these yet but my plan is to get a empty water cooler bottle and mount (by method to be determined) a clear plastic hose with a shut off valve(probably a ball valve) at the end of the hose. a hole would be drilled on the bottom of the bottle so a funnel can be used and can be sealed by a rubber plug that similar to a cork plug. This all would be held off the ground by some sort of stand. Since you would already be taking the oil from the top area of the drum, you could then put the bottom stuff into the jug and let settle for a bit then drain off the antifreeze, water, etc. that won't mix with the oil. You could use other types of bottles such as a white plastic utility fuel can or a restaurant shortening container, but the water bottle is truely clear for seeing the contaminents and the plastic is pretty thick.
