Whew! A real project and you used good quality components cept for the plastic barrel. When you turn that puppy on she is gonna vibrate off that barrel. You need to use a steel drum and solidly mount the centrifudge to the drum or just mount the centrafudge to the concret andpump the oil into the drum. I use lots of centrafudges for honey extraction and things gotta be perfectly balances or they walk.
Question, what is the purpose of slinging the oil against the sides of the pot at 3450 rpm anyway? How is that gonna separate anything out?
