Sure, I'll give you the condensed version and some links to bio-diesel forums where you can learn as little, or as much as you want. I want to stress that this is a very condensed version, but it isn't near as hard as it sounds.
Start by gathering up your waste oil. Chinese/Asian are the best sources as they tend to use a higher grade of oil.
Filter the oil to get out as much junk as possible. Next step is to test the oil to determine how much methanol and sodium to use in the conversion process. You then mix the sodium and methanol together, this is your catalyst to convert the veggie oil into bio.
Pump your waste veggie oil into your processor. Mine was what is called an "Appleseed", basically a hot water heater converted. Pump your oil into the processor, add your methanol/sodium mix and circulate in the Appleseed for a couple of hours at 130 degrees. Shut off, and let sit overnite. Filter off the crud that drops to the bottom.
Now you pump your "bio" into your was tanks. You add water (yes water) and "bubble" it. Bubbling causes water water/air to rise to the surface which captures any remaining soap/sodum/methanol and it then sinks to the bottom. You do this for a couple of days, draining off the water periodically until your PH measure is the same as the tap water you had started with.
Drain your "bio" and put in your drying tank. This tank basically is used to heat your mixture to about 180 degrees or so, while circulating it trhough a couple of fllters. You keep doing this until it's nice and clear. Test by putting in a freezer and cooling to about 34 degrees. If you can read a newspaper through your clear container at this temp, then you're done.
Throw it in the tank and go.
Again, this is simplified, but it's not that difficult, but very time consuming. My cost in the last year I did it was about 40 cents a litre. Current diesel cost here in Atlantic Canada is $1.22 a litre.

Excellent book by "Girl Mark" avaible on how to make bio, a must if you want to get into it.

Fire away with any questions...
Yes, Please share with us on how you made your ''home brew Bio-diesel''!!:thumbup1gif:
Around here in Eastern, Kentucky... You can't find Bio-Diesel anywhere!
I run ''off road diesel'' in my tractor sometimes, But right now it's priced as high as regular diesel.
