OK, so phase one was acquiring a suitable candidate to convert to a veggie car and get it running. Check. Even though that process took about six months to complete. Not to get it running, just to get the title straightened out took that long. The folks at the DMV sure know how to drag their feet. Jus’ sayin’. So phase two involved lining up a supplier for waste vegetable oil and getting it filtered and ready to use. Check. I talked to the local café about getting their oil and they were more than happy to accommodate me with a weekly supply. I just need to provide them with empty barrels, not a problem. After doing some Youtube research about veggie oil it would appear that the best way to filter the stuff and get consistent results is to use a centrifuge. This device takes out the solid particles and any water that may be lurking in the oil. Trouble is, they are expensive, the store-bought ones are anyway. About a grand or more, ouch. What to do? Light bulb moment! I will just build my own!
These pics are the start of my bowl. I found an 8″ chunk of solid aluminum in my collection of stock and proceeded to start whittling. This was then bolted to an adaptor that mounted on an electric motor that spins at 3450 rpm. This whole assembly is then installed into a five gallon bucket on three legs. Ta da! Centrifuge, cheap! Add in some plumbing and a drain valve for the clean oil to exit the bucket and away we go. The thing actually works but my used electric motor has some play in the bearings that will have to be addressed in order to eliminate some mild vibrations. Here is the finished product.
