Home made WMO WVO waste motor vegetable pressure cooker centrifuge DIY #4

Here is one of my home made centrifuges cleaning waste motor oil. I am using a 1/3 hp 3450 rpm motor and a vfd to spin it a 6000 rpm. I am using the oil to feed my 1988 Ford 7.3 IDI.
Cleaning out the sludge after running 5 gallons of waste oil through it.

Thanks for posting the vids- it looks great! Do you have a vid that details how you built it and what you used for the "Bowl" inside? Thanks

Thanks for your comments. The bowl is a Raw Power centrifuge PoBoy Kit. Looks like it is currently on sale for $200. My kit was made with a Mirro pressure cooker. Sorry I don't remember the model or size but it was one of the biggest ones. I used a flange from Mcmaster Carr p/n 1764K25. It fit in the bottom of my pressure cooker to separate the good/bad oil. I sealed it with RTV silicone. I then added a bearing inside the centrifuge to support the motor shaft. It was a 2-1/2" square by 1/4" thick piece of aluminum with a bearing mounted in it. This was sealed to the bottom with RTV silicone to prevent oil from leaking down the motor shaft. The only picture I still have is i83.photobucket.com/albums/j309/bslaws/Pressurecooker_zpsfec30b07.jpg which shows me machining the motor holes and shaft holes in the pressure cooker.

Hi, looks like you were ahead of the curve with the centrifuge 8 years ago!
I am looking for a budget way into centrifuging WMO and amazingly bought a ancient Tefal pressure cooker at the recycle thinking it would make a great vessel!
Did you carry on using this setup I wonder?
I'm looking for a second hand centrifuge bowl to continue my project but may end up using something like a steamer base pan with a lip welded on...
Love more details of yours, like moter spec etc?
Cheers!
