Any update on the setup
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
UPDATE
just got a PM and realized that i had not updated this thread. I have got the centrifuge to work the to a point that is exceptable to me. I started by mixing 15 gallons of diesel into 35 gallons of diesel and letting her run. at this point i started getting out a hard graphite like substance not just a tar like slime when i cleaned out the centrifuge. i was able to get the oil to a dark tan color. i now have started adding 5 gallons of E-85 and 10 gallons of diesel. this has made the process quicker and the color was lighter however was cloudy. i soon will try my hand at some WVO. all in all i am satisfied with the centrifuge. if i had to do it all over again i would buy a bigger gallon per minute centrifuge to make the process faster. hope this helps.
I have the 55gph PA Biodiesel setup and it hums but it's not too loud. I have it attached to an open top drum, but the top IS secured, so that may be your issue. The fuge seems to be louder while getting up to speed. Once it hits the 90+ PSI it needs to spin optimally, the hum is still there, but much lower. You may also want to check and see that the fuge is level.This is my first post, but I've been reading quite a bit. Anyway, this was a primary interest that I wanted to read on as my Father in law and I have acquired a few trucks (and counting), and he insists on WMO for fuel, so he also purchased a PA Diesel kit. Not sure which one it is, but I know it has either the 108 or 120 centrifuge.
We have 2 large 140gal aluminum semi tanks which we store finished oil in (we're gathering oil from the assortment of small businesses in out little town to include gear oil, tranny, motor oil, etc.)
I have 2 questions. I've read somewhere that the PA centrifuge will filter down to like 3M, but he insists on having a 80M barrel filter under the lid. Is this overkill because I think it is (running the oil through the centrifuge and having it run through a micron filter?)
Second Question is: This thing is LOUD!!! Not like abnoxiously but loud enought to where you have to almost yell to talk to each other. I'm thinking it's because the lid of the barrel is not strapped on (due to the filter being there) but it doesn't seem to bug him. Do you think this is the reason or could it be something else?
I'll try to snap a couple of pics of this system in the next day or so when I have some more time.
Thanks.
So I know it's been a while since anyone's posted to this but E-85 should not be used to thin out the mix, yes specific gravity is key(actually viscosity is but they're pretty close to each other without a vizcup) but if you do just some simple things your engine life can be extended even with the excess carbon buildup from wmo. WMO has approx 10% more btu's per gallon than diesel but it also creates more carbon buildup add in ethanol(e-85) and it redeuces the flash point of the mix, which in turn cools the exhaust gasses too much and allows the soot/carbon to build more rapidly. If you use another petro product you can reduce the viscosity and btu's to approx what diesel is, gasoline works ok (and it's btu is approximately10% less than diesel) but due to the fact that in most gas mix today there is ethanol in smaller amounts kerosene works even better.UPDATE

Hello,I had a dieselcraft setup originally. Was not happy with it and built a new system around a motor driven unit.

If you read through the first thread, you can see all the fun I had getting the dieselcraft unit working. I am much happier with the motor driven one.

No, if you mean those links in post #18, they went dead long before this last change.Interetsing read, but unfortunately the links are no longer valid. Perhaps as a result of website make-over?
