its not the way id want to goidk how well balanced a bowl would be if I turned one on the lathe, plus it's a hell of a lot of material to move from a solid lump to make a bowl
there's a foundry not far away from me, I guess if I made a form I could have one cast in ali... but then I've no idea how well balanced it would be? - I think JimIRL was planning that?
i dont think anything will be balanced... i mean certainly not as soon as you have messed with it
id imagine it better to use somthing ideal for the job in other respects, and then balance it
Honda 50, 70 & 90's have them to keep the oil clean, I was amazed when I found out, From memory one of the 70's Scania bus engines used one to keep the oil clean too
Some Massey Ferguson tractors had them too. They abandoned them because they couldn't get mechanics to a, figure out how to clean them and why, and b, trust them, as it's not like a filter with a barrier that stops dirt and people think it's not foolproof. In fact, many really large engines have a small industrial centrifuge constantly cleaning 10% of the total every hour. These centrifuges will take out carbon Down to 3 microns and anything else down to 1 micron. They are way better than any filter fitted to an engine.Honda 50, 70 & 90's have them to keep the oil clean, I was amazed when I found out, From memory one of the 70's Scania bus engines used one to keep the oil clean too
Landrover TD5's, and the old Ford 2.4TDCI 150PS had replaceable centrifuge filters on them, as well as standard full flow filters.Some Massey Ferguson tractors had them too.

As i recall, they were spun up by the oil pressure entering the bowl through angled nozzles. Not sure how much power they used. Certainly filters are simpler and work, but fitting one if you have a centrifuge would just be belt and braces in the event of something fairly catastrophic happening, and the filter would last far longer, since the centrifuge would take pretty much everything out, which is why big industrial diesels use them.Landrover TD5's, and the old Ford 2.4TDCI 150PS had replaceable centrifuge filters on them, as well as standard full flow filters.
I suspect they fell out of favour as they took power to run (every marginal gain is vital when chasing emission targets), and materials/filtration/oils improved.
