Suggestion for filtering WVO
You can make a cylinder shaped filter element by taking 2 solid ends, connecting them with steel rods an inch or 2 apart, and winding wire around and around the resulting armature. Believe it or not, this is what the 1958 and earlier Mercedes diesels had for a fuel filter. The fuel squeezed thru the spaces between the wires and when it got dirty you took it out and washed it off.
I wouldn't suggest this for a final filter but if you made one of these you could catch almost all the gunge and make your good filter last a lot longer. No reason you couldn't make the armature of wire mesh and wind it with wire. |
Basic filter
Nylons make great filters.
If your wife wears them first, they are free. My wife wrecks a pair every week. |
Bummer. I don't think I know anyone that wears nylons!
|
Clothes from the 2nd hand store (old shirts) work okay as well.
I use paint filters for mine..then run it through a car filter post biodiesel reaction. :) |
Nylons and other stretchable material does not make good filter material as, when the material stretches the holes in the weave open up and let bigger particles through.
Cotton and polyester shirts are good, but what rating are they? I bought a 5 micron bag filter for my WVO filtering. It cost me Au$8.50 and are readily available. If the filtering starts to slow down, you can wash it out and use it some more. I wash mine up to 10 times each before I consider them too far gone for use as 5 micron, I then use them for coarse filtering, prior to the replacement 5 micron filter. As I "cold filter" my oil, the effective filtration is many times better than 5 micron, due to the oil having to pass thru the accumulated solid oils which have been retained in the filter. The filtrate and tallows are used in a mix with sawdust, packed into milk cartons and used in my wood fired home heating system. Tony The Wizared of Oz. |
Tony! What a great idea!!!!! Does it burn well? Leave any residue? Has anyone tried burning glycerine (from biodiesel?)

Got a turbo on that thing? :D |
Any thoughts out there about using a Lubri-finer from an old semi-tractor? I just pulled one from an old Freightliner that had a 400 Cummins diesel in it. I haven't had time to experiment with the thing yet. For those who don't know what a Lubri-finer is, it is a huge oil filter that is mounted externally from the engine on semi trucks. Oil is transfered to and from it with some rather large hoses.

http://www.mcmaster.com/ page 329 right down to 1 micron if that is where you want to go. Always nice to have options, however the jeans thing is interesting and economical too. |
MCMaster has so many to choose from. :eek:
Which ones would you suggest? |
Would coffee filters work?

They will work. :EDIT: :o They work ok for preliminary filteration, not final filteration. |
