Simple Centrifuge Home build

[FastCote]

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.

The first parts are the most expensive part of the project (but worth it). bowl machined from a solid billet of aluminum and TranTorque keyless bushing. $500 from Simple Centrifuge

I needed and enclosure big enough to house the bowl, mount a big-ish motor on the bottom, and allow me to mount structural legs on it. I found this baby at a local restaurant supply store for a mere 40 bucks. Its BIG and heavy walled. Perfect find!

The bowl provided by simple centrifuge self drains when stopped (a real bonus) so you have to provide a splash wall to keep the slops from mixing with the clean oil.

I went the cheap route again and stole dog bowl for the purpose. FIVE BUCKS.

The dogs were NOT terribly excited by the whole idea!

Perfect fit (almost)

OK, no welding but a few tools were used. Air grinder to cut off bottom of bowl.

Nice straight cut for novice freehand.

3450 rpm Baldor motor wired up and ready.

Motor bolted up and splash ring dry fit. Buggered up the mounting hole at 8 o'clock. had to oval it out to get it to fit. Oh well, I'm not machinist.
