I think I've overcome two issues with oil filtering, which are:
1) How to pour oil 8' off the ground from an 90 pound drum, and
2) Dewatering the oil

First the height/weight issue. No, not mine, though I have the
healthy weight of someone a mere 1 foot taller. I'm talking about my
contraption that has me pouring oil 8' off the ground. I modified the
lid to a 5 gallon bucket last night, and glued a 2" female endcap
fitting to the top of it, so that I can thread my filtering
contraption onto it. (Said filtering contraption being a 3' length of
6" PVC that is necked down through a 6-to-4 slip bushing, into a
4--to-2 slip bushing, which is fitted with a 2" male fitting. At the
top of the 6' pipe, I put a 30 micron sock filter over the top of the
pipe, and use a clamp to secure it. Thanks to Mark Mitchell, the sock
filters are very cheap -- a jeans leg cut off at the crotch and sown
across the bottom, works great. The 2" male fitting at the bottom of
my filter lets me screw this into the top of the fitting I've glued
into the top of the 5 gallon bucket lid, or into a steel drum. This
should let me filter oil by lifting the drums only 4' off the ground,
which is far more manageable. If that is still too difficult to
achieve, I'm thinking about using a shop vac to pressurize a drum and
push the oil out, though I suspect there isn't enough horsepower in a
shop vac.

That's enough for this post... I'll cover dewatering later. In fact,
in the next post.
