VegPup,the folks on the timebomb2000 board are quite interested in the process. write us up some details when you get the time. I am anxious to give it a go,esp seeing where the world oil price/supply is heading.
Also,where are you located? If this guru is sitting on that many diesels,we need to know!
C'ya...
Sorry for the delay. I've been working on some new (not really new, but new to this task) equipment for making biodiesel.
Biodiesel has been around and in use since before WW II. It was first widely used in South Africa; they had oil-producing crops, and no petroleum. Since we in the U.S. had plenty of petroleum and low fuel prices until recently, there has been little interest in biodiesel.
Interest has picked up lately because of the drop in sulfur in diesel fuel, with more sulfur to be removed soon. When the refiner removes the sulfur, other things are removed that previously provided the lubricity needed to limit wear in some types of diesel pumps. In addition, diesels are under the gun at EPA for other pollutants besides sulfur. So we're likely to see even more expensive fuel in the future.
Biodiesel has substantially higher lubricity than petrodiesel, and produces much smaller amounts of most pollutants. Sulphur emissions are almost negligible. CO is much lower. Particulate emissions are much less. Nox is about the same as for petrodiesel. In addition, since biodiesel is produced from plants, the CO2 produced by burning it actually results in a net reduction (or at worse, an even exchange) of greenhouse gases. Burning fossil fuels results in an increase in those gases in the atmosphere.
Now, for the real reason we all make it. It really can be cheaply made, if you don't count your labor as a cost. Used vegetable oil can often be gotten free at local restaurants. Sodium hydroxide (lye) is cheap. Methanol is widely available from solvent suppliers, speed shops, or racing fuel distributors for about $2 per gallon. If you can get the oil free, and methanol relatively cheap, your costs end up around 40 cents per gallon.
Equipment can be as simple as 5 gallon paint buckets, an electric drill and an old blender. Or it can be as complicated as my latest effort, with pressure vessels, high-volume pumps, vacuum distillation apparatus, etc. Making it in small quantities is fun. Making it in large quantities seems more and more like science.
Now, for how to make it. My best advice is to go to these sites. There is a lot of information available. Read it all.

Then the forums:
http://www.egroups.com/group/Biodiesel
http://biodiesel.infopop.net/2/OpenTopic/a/cfrm
Links at all these places will take you to many others. If you can read German, there are still more sites in that language.
Have a ball. It's really fascinating.

Oh, about the local guru. The world expert on Isuzu 5-speed transmissions. The owner of many diesel trucks and troopers. I disclosed his name and phone number on the net about six months ago, and he has only recently resumed speaking to me. He intends to fix or restore all the ones he doesn't already drive. All forty or so of them. Gathered from all over the U.S. He will only occasionally sell me a part. But his advice is freely given, and much more important to me, so I don't want to offend him again. If technical advice is what you need, I'll put you in touch with him. If you want parts, I probably won't. Sorry.
The guru and I live in central Arkansas. Really.
Good deal,VP! I read up on it and I'm anxious to givi it a go. Information like that could become priceless soon. Aside from my fondness for my TDi Troop I am very into preparedness.
I drive big rigs for a living and am up on the EPA and low sulfur issue. I will be trying to educate myself further on the bio juice. I can see the possibilities for fleet use and the recycle angle makes it very attractive to the greenies.
I hear ya regarding Guru man and I agree. I'm just hoping I'll run across another TDi unit as a spare just in case. mine is at 235K miles now.
Try looking up a company called "GREENERGY" i believe they are German based, their Bio diesel product is derived from a common crop know to us as oil seed rape, farmers are hopefully to enjoy a better return on their harvest of rape as a result of it being blended with a % of petro diesel, it is not widely available yet but with the emmisions situation its only a matter of time.
