Alright, after looking through probably 80% of the threads involving biodiesel processors I have yet to come up with the easiest cheapest method. I mean there are appleseeds, bio-pros, etc. Any thoughts on how to make the cheapest, most simple processor? I know it depends on what materials you can come up with like barrels and such but could someone help a rookie out? I know it's asking alot but diagrams are great since people can make the containers out of different things. $5?? IT"S KILLING ME!!!
