Sweet, you've spend $300 to do what a $.49 timing motor would do.

great rich, since it is so easy would you mind posting your plans to make such a unit and location of where we can buy all the supplies.

Thanks!!

Oh yeah can you post a video of you 50 cent gizmo working as well.

Didn't think so;)

Comments like this really bother me. This is why alot of people (including myself) tend to "lurk" instead of "post" on this board. Someone is always waiting to slam you and your ideas! I applaude the fact that someone can think outside of the box.

Re: Re: Best random flow Tunze on a Wavy seas

I'm buggin, I think Orion did the same thing with a Sea Swirl but I can't remember if it held up. A long time ago I saw someone do this with an oscillating device, but it was quite a DIY project, seemed bulky and probably ended up costing quite a bit. The WS+ will have a Tunze mount, but its not going to be available until May. I started a thread on the WS sponsor forum.

Why do people mouth off about things they know obviously nothing about?
 
There used to be a product called Osci-Wave that I bought several years ago. It was basically the same concept, although you couldn't adjust the speed. It moved pretty slow, but rotated like 120 degrees or something. IIRC, it was much less costly.

I actually pulled it out last night and am going to try to get the Stream on it. I don't know if it'll be too heavy, though. I used to run it with an MJ1200.

Fliger, I mouthed off because she spend $300 to do something that people are doing with a grand total of $4 in parts. I do know something about this. A 3rpm motor will cost you less than a dollar, and will do everything this does.

This is just another example of people thinking that wasting money should be done.
 
I remember reading about that. I've seen some failed attempts in the past, and as I've had a 6200 running loose in my tank before, I don't wanna be the test monkey. ;-)

The biggest hurdle is handling the backpressure of a Stream. I've seen home made versions using $10 fans, but the biggest thing I've ever seen on them was a smaller SEIO.
 
Fliger, they seem to be using PVC for the axle, which no pump is going to break, so as long as you build it (with multiple hanging rings for the axle) so theres no torque on the cam/motor, it should last forever.

Now, the OP did do something neat, its just way too expensive for most of us.

Figure thats $500 to have 2 tunzes spin.. You could buy a controller and a third one for that.


Personally, I'd be more worried about a Tunze breaking something like this, than a home made one that is made specifically for this purpose.
 
Some folks would rather pay more for a quality unit that won't cost them any sleep. I'm sure I could take $100 in parts and build something that works, but experience has taught me that I'll be buying the WS in the future anyway, and the $100 in parts will be another deposit to the DIY box downstairs.

Different strokes I guess.
 
Ewan, I'd sleep less well havign something like a WS or a SS spinning with a tunze on it than a 1/2" PVC pipe. Sched 40 PVC can take a lot more force than the motor on a wavy sea can. The wavy sea wasnt designed to have things hanging off it.

And FWIW, you could build somethign that works for about $10, not 100.
 
Eliminating torque would be very difficult. I think if you really have the wherewithal and time to do a DIY project like that (and are ok with the lack of "style") - the best option (IMO) would be a hybrid of Reefvan's - and the the DIY above. All the pressure goes onto the wall of the tank.

To be honest, even with the WS+ at $250, I'm still a little nervous about putting a Stream on the long term. I had a Tunze groove wear down and it fell out of its clip. I lost some nice stuff. Its been fixed (Roger is awesome), but I learned the hard way what a Tunze on the loose can do. ;-)

Anyhooo ... I love the ideas cuz many people have tried to do this - oscillate Tunzes. Its gotta create unparalleled random flow. If you could hook up a 6200, you wouldn't have a dead spot in your tank. The controller on the WS also sets six speeds and angles with a few keystrokes.

That's not 100% true, from the beginning they've come with attachments for powerheads. Not 3,000GPH Tunzes, but powerheads. :)
 
I dont see a reason for speed control in this though, I really dont see any benefit to it. Put one oscillating tunze on each end, and have them rotate at slightly different speeds, and I dont think you're going to get any more random flow by changing the speed the pump is running...

if thats what you were talking about.


As to eliminating torque, you just need cuffs for the pipe to sit in. As long as you have atleast 2, there will be no pressure on the cams.

Lets to business my friend, this could be an exciting commercial venture. :thumbsup:

Just because something comes with something, doesnt mean it was designed for it.

Sometimes at the end of the design process, you reallize you could throw something on and it will work. Like you said, Tunzes arent maxijets.

I was just reading something about a WS exploding after someone put a Penductor on it.... That scares me.
 
Well neither you or I will ever know if it was designed for it or not. BUT, I did talk with a guy at WavySea about this (when only one had been sold to BlueStag) and he did tell me that WavySeas were basically designed to be everything that SS was not. To be used as a sump return, a CL return, a submersed PH with tubing into the top of the WS, or to hold a PH. There have been pictures on their website of every application listed before they sold the units. And for those who have used both SS & WS, they definitely succeeded.

Anyway, like I mentioned - I'll put the Tunze on it, but I'll watch it closely. I will probably end up putting the MJ Mod on the other standard WS since I figure it's probably pushing 1,500GPH.

And on the speed control, trust me, its a nice feature. ;-)

Rich I know it "can" be done....but I still can't seem to find you DYI plans anywhere? Please show us you 50 cent unit that works so well.

Also these units were designed to have "thing" (pumps) hang off them. You may want to try some research before flaming people and NOT being able to back it up.

I would love one rotating and on the controller pulsing!
 
Mchava,

As most of you know I bailed for awhile, but I had built two of these in my 180 based on a design by reefvan. But I like your attachment much better than what I had.

Here is a pic of the device I used:
Actuator.jpg


They are designed to open and close dampers in an industrial environment, waaaaay more torque than a puny (although great) Tunze.

The bracket on the Belimo held a plastic dowel, I clamped a 6100 stream to the dowel by modifying the back cover of the stream. Your idea doesn't even require that. Use the hardware supplied by Tunze and modify the vertical brace to fit into the bracket on the damper.

Here is the data sheet. Don't freak. The first pic on page 119 are the connections. A 24VAC supply (black and red leads)and a 3.5VDC to the white will drive the damper 95 degrees every minute or so then return.

Search ebay for Belimo. I have 1 pair left (hint, hint), but you can get them for about $40 each if your patient.

It was a great DIY and nothing will match a pair of them.

PM or GL, it was not very difficult.
