Question for all you sump building pros

[jsodwi]

I was wondering how to build one of those spinning return setups over the drip tray. I saw one at a fish store overone of their central filtration systems but couldn't really figure it out by looking at it. It had 3 pvc tubes drilled with small holes but how is it plumbed in and there must be some sort of bearing in there to make it spin. Am I explaining it right?

There has to be someone on here that has built one of these??

I've thought about that, but I've never been able to find any info on how to get it done.
I hope someone knows.

I machined mine (center section/bearing/slip joint) from delrin, Unless your a machinist or don't know any better D) and have access to a lathe, you might just try looking harder.

They were used on S/W systems, holes were angled to drive it.

Problem was the holes/slip joint clogged and needed attention, and they were more expensive to make than a stationary spraybar.

And honestly I'm not sure they're made anymore.

Rallysman... Hint...Black box engineer it.

I have seen those before. Honestly, I can't see how one of those has an advantage over a regular drip plate. Seems over engineered IMO.
