The oil supply drum is not pictured. They will sit side=by-side with an air powered drum pump, pumping through the heater stack to the centrifuge, then straight down into this drum. The clear acrylic lid is also cut and installed on top.

The bowl loses its shape a little once the bottom is off. Hopefully the JB Weld will firm it back up.

3/4 in hole drilled and tapped for 3/4 in nipple (not shown. To be added later once bowl height is established). Also, i buggered up one of the motor mount holes - i had to oval it out to fit. JB Weld to the rescue.

First Parts - DSC04725.jpg

I decided to take a stab at building my own centrifuge based of the bowl produced by the folks at www.simplecentrifuge.com and based on a plan nicely provided by Leon Griffin at www.WVODesigns.com The first parts are the most expensive part of the project (but worth it). Machined bowl and TranTorque keyless bushing. $500 from www.simplecentrifuge.com
