DIY Swirler Stein

[nightOwl]

007Bond - Thanks for the tips! I will try to keep those things in mind when building mine.

With the length of my pvc shaft the force of just the 40 caused the shaft to be forced backwards before I added the 60,...you need to keep the shaft straight to preventing binding which hinders rotation. The standoff fixed it. The shaft in my tank is unusually long, but I think with the power of the WP pumps even on shorter shafts something would be needed to keep it straight.

Yeah I use a project box with a plug in the side from the motor.
I have things tore apart from a move right now. I will take a couple pics when I get it back together

My rock is not from BRS

hollback - What's the parts list on this? I think I remember reading that you had some custom cnc parts. I see a brain in yours...is that a custom board or something in picture three?

Sure, here you go:

I'd have to take one apart to see what all is in there. I know the circuit board is just a cheap pwm speed control for China.

Well, these have been running continuously since the beginning of 2011 and I will never run stationary powerheads again. Seeing what this has done for the health and growth of my coral, I honestly can say I will NEVER run stationary powerheads again.

Been wanting to do one of these but the images in the link posted above don't work anymore

Thanks for keeping us posted on the longevity of your unit!

Ditto!

Kind of sucks that photobucket killed a lot of valuable info out there.

 

[hollback]

Yeah, no fun having to fix images.

I updated the photos in my original post here:

Got any photos of your gearing? More specifically how you connected the pipe holding the tunze to the arm. Is it water tight?

There is a CNC'd washer inside the pvc pipe with the rod going down through it. At the top, is a threaded compression fitting holding onto the rod with a threaded pvc fitting attached. If that doesn't make sense, I can draw it.

This might help.

I did change how the plumbing now connects to the pumps. There is a pvc 90 that connects perpendicularly to a 'paddle' mount that the pump screws into.

A drawing would be awesome please.
I'm guessing you basically built a pipe inside a pipe just like the Sea Swirls however you used washers instead of o-rings?
