Kinda off topic, but not completely. Going to weld up the stands and plumbing for it.

Just getting into the Bio-Diesel concept. The commercial home refineries are expensive. $4000.00 and up. One can be made at home for around one to two hundred dollars. If its worth having its worth making yourself.

Before I get flamed for the price of commercial bio diesel let me repeat myself. I'm going to be making it myself. I have some Chinese restaurants lined up to give me the used oil already. 0.75c VS 4.05 per gallon!

Here is a link to a good site I found on the subject.

A part of the project will include changing out my old gas burning V8 in my 67 chevy van, and putting in a diesel engine. Plenty of welding for new mounts, cross members, and storage tanks.
