ok, thanks a bunch for the info, im excited to build my own now. ill have more of a gravity feed and a barrel heater for now, but thanks again for making this to easy.
Simple Centrifuge Home build
After reading tons of messages on various forums I decided a centrifuge would be ideal for my filtering/dewatering system. I read trade offs of the pump driven style (Dieselcraft) vs a "real" centrifuge based on components from the guys at Simple Centrifuge
After sitting the fence a bit and hearing that the turnkey system from simplecentrifuge was going to cost $2,200 I decided to jump in and build one myself. I stumbled across Leon Griffin at WVO Designs who shares an open-source design using the simple centrifuge bowl and a welded enclosure.
I decided to spin a version of his design and try to build one as cheaply as possible and more importantly require no welding.
What follows are some pictures and captions detailing my progress.

what was the Baldor motor part number you used? how did you find the correct shaft size, did you call?
Baldor part# JL3405A.
That is the model that fits the simple bowl.
I bought mine from MacAndMac:

awesome, thanks
$550 for that machined bowl! dang, there has to be an equally well balanced fuge bowl out there that does the same job... any ideas? if i had the material i would have my machinist do one...
Very interesting thread. On another board (I think!), I discussed using 3-4 oil/fuel/bypass filtering system - now I'm thinking centrifuge is the way to go.
I agree with another poster: surely that bowl can be machined/produced for less than $550???

I thought the same thing. I just got a price though of $180 for material a piece of 5" long 9" dia. aluminum. It would give a better price (price per inch) for longer piece, but thats all I would need.Very interesting thread.

Cheap centrifuge testing - an Acme juicerator, it works! - Topic Powered by eve community
its cheap, and not high quality, but for the price you cant beat it. im going to try it soon, granted i havent read the entire thread just yet, but it seems a great temp solution until i can build a proper fuge.

Thanks for the great pics and write up . Would it be possible ( clearance wise inside) to fasten the leg flanges to the outer bowl with machine screws and nuts sealing them on on the inside with JB Weld ?
Can anyone here come up with a lower cost rotor ?
I will wait for a few more months for Bruce and his $500 ish CF
before I go forward with something like you have done .
Greasecar Vegetable Fuel Systems
BTW - another CF - BioFuelCentrifuge.Com ( priced at $1600 )

yeah, im all for this build, its just that bowl, there just has to be a lower cost solution... for now i may just do the juicerator build until i can afford or find a better bowl.
ok, as i am almost down with the acme thred i see that it may not be worth the trouble. even if it does balance i dont know that i would trust it. im looking for an unattended setup. but i did find this, i have no idea how much a machine shop would charge to machine a bowl and i dont know yet bout getting a bushing but i did find the bowl material for far less...

This should solve your problem -ok, as i am almost down with the acme thred i see that it may not be worth the trouble. even if it does balance i dont know that i would trust it. im looking for an unattended setup. but i did find this, i have no idea how much a machine shop would charge to machine a bowl and i dont know yet bout getting a bushing but i did find the bowl material for far less...

very interesting. think a wood fuge would hold up long under those forces?
:headbang1: Dude ! that was awesome. I've just joined the forum & I soon found your thread. I got totaly sucked in. I had to read the hole thing all 73 posts!
I'm in the proccess of building a filtering system, but I'm seriously concidering ditching the idea now. I have saved that website where you got the bowl from. Excuse my tiredness but i'm a little lost with how the motor is conected to the bowl. I have a 3.5hp motor & I was trying to think how I could conect the bowl to it. Anyhooo I'm guna have to go to bed. I'll check it all again tomorrow though. Today I should say.

The motor is simply through-bolted from pot down. I then put some epoxy on the bolts inside the pot to prevent oil leaks. I think the motor takes 1/4-20 bolts but I can't remember for sure.
Hi, yea when I said bowl what I actually mean is the fuge. The bit that cost the money. I'm going to have another look at all this but what is the dog bowl bit for again? Have you got any video of this baby in action. So if I've got this right, the oil trickles in to the fuge bowl that is spinning, all the crud stays in there due to gravity. Then when the fuge bowl fills the oil pours out over the top of the fuge bowl & into the big cattering bowl. Then runs out of the hole as clean oil. Is that right? So whats the dog bowl for? I notice that the dog bowl seperated the two holes in the cattering bowl, but wont the oil be clean when it pours out over the top of the fuge bowl?
No doubt I'm missing something here.

Sorry, mis-read your question...
the bowl connects to the shaft by using a trantorque nut. This thing applies pressure both to the motor shaft (inward) and to the bowl (outward). It does it in a very concentric way (.001 something). Here are some pics:

This thing comes with the bowl when you buy from simple centrifuge. It is a big improvement over their original design.
As for the dog bowl....
the centi bowl has drain holes (3 of them) to allow the sludge to drain through a separate hole in the pot. this only happens once the bowl stops spinning. The dog bowl acts as a barrier between clean oil and slop oil so you do not get contamination.
see a video of the idea here:
Simple Centrifuge ...putting a centrifuge in every garage!
In practice, my oil is so dirty that the crap left over will not drain (too sludgy). I just use a rubber spatula and scrape it out. No big deal.

O I see, now I get the dog bowl. You didn't get your motor from Simple Centrifuge did you? So I could buy the fuge from those guys & hopefully use the motor I have. What hp is your motor? Mine is a 3.5hp
your home made CNC is a real neat piece of work! I was looking for a project like that but to adapt for a plasma cutter. Do you have build plans you are willing to share?
Thanks!
Thanks!
I am happy to share what I learned. The design is from a guy that goes by the screen name JoeCnC. I met him on the LumenLab forums (for building home projectors - another cool project). The best place to look is on the CNCZone forums. He has an entire section for his designs. check it out here:your home made CNC is a real neat piece of work!

Mine is the design called JoeCNC model 2006. I have not kept up with CNC stuff, but i think he has a cool design made from 8020. That stuff is cool.
