the swirler-stein

[grochmal]

Shouldn't matter which way it turns, it'll work both ways.
I got my new motors in (see above) and baby are those quiet.
I can't wait to get them hooked up.
They're a little tougher to connect to since the shaft is so short and funny shaped but the difference in noise is amazing.

I think I might... I think I got three of them, planning on building two but just have not had the time yet. Let me look when I get home tonight.

how do you wire this? how is the power cord attached. Thank You.


Chad.

 

[grochmal]

Buy a power cord (or use an old one laying around) and cut the female end off.
Buy some wire connectors from Radio Shack or other such store and crimp them on the end of the cord.

These connectors should slide right on the connectors on the motor.

Soldering makes a much safer and more secure conection, then shrink tube it to help keep moisture out and insulate the connection.

That'll work better if you have a soldering iron.

What I meant was how do you make it stop at a certain point and then turn the opposite way and back again so it is like a sea swirl?

 

[boviac]

You make a four-bar device. Same way your windshiled wipers work on a single directional motor. But if I recall correclty I believe some people are using a larger wheel that pulls a line. Concept similar to steam driven locamotives.

Good luck.

 

[Joshsmit56001]

That makes sense

3 rpm motor

here is another motor i found since the one everyone is using is sold out. this is .5 rpm faster but otherwise the same thing.

im gona order 3 of these

 

[bosborn1]

Chad, How did that motor work out. I bought one from ebay but the gearing stripped out within 2 minutes of operation under no load.

I have all the boxes built, Now I need to find motors again.

[mmoore0803]

I made one and the motor is still running strong for me

i bought 3 motors, and i really like them. the biggest problem so far was making something to fit the thing that spins. i have had it running for 1 full day now and its fine, i havnt finished it yet so i havnt run it longer than just a day.

 

[Chad Vossen]

just some pictures of one im making, cost me 5$ for a 24"x24" peice of acrylic, alot cheaper than the electical boxes! plus this looks better and has more flexibility in shapes. i should be finished with it tomorrow, i also spilled a can of PVC glue all over my new carpet ... OOPSSS!!!

 

[Chad Vossen]

oh man, after looking at my own picture, i figured a much better idea. ill have a picture later on my second swirl-stein. actually, there are a few improvements ill have.

 

[Chad Vossen]

ok, the swirl-stein is finished. though pictures will come tomorrow.
i also finished the maxi-mod thats going with it,

(i didnt post them as photos since they are off topic) not that it helped any.. lol

 

[hahnmeister]

Here's mine... made a 3"x5" acrylic box...

Made a corner mount for it from 3/8" acrylic. Drilled holes in the box to hold the shaft and box in multiple positions, or two boxes in tandem.

Then I made the shaft that goes to the powerhead out of 3/8" OD acrylic pipe, and 3/8" ID acrylic pipe stuck together and drilled.

The powerhead is a MJ1200 with an octura 2035... tons of flow.

If I want to change the range of oscillation on the device, I simply move the pin on the motor's wheel inward or outward... right now its set at about 100 degrees, but can go over 120.

 

[Chad Vossen]

thats really nice looking. would you be willing to pm me the distance from center you drilled your holes? im having trouble figureing out how to get more than a 40 degree angle lol, i just keep making it jam.

 

[hahnmeister]

You mean on the disks? The distances are relative to each other, and the distance on the motor's disk from the center determines the degree of oscillation. I would suggest you start with a 2:1 ratio (oscillation disk to motor disk ratio) to give you about a 90 degree arc and go from there.

 

[bosborn1]

Holy cow Hahn!!! Thats a huge shroud ya got there!

Scott

 

[hahnmeister]

Yeah, that shroud looks a little long, but its also running an octura 2035 (thats a smaller prop at 1.38", but its also got a steeper pitch than a dumas 3004, so more water through a smaller pipe). Im replacing it this weekend though, as the slots need to end a bit further away from the end... Im actually getting water coming out of the closest-to-the-prop intake slots! Actually, its not that long... 3".
