the swirler-stein

grochmal,
How long has it been running since the last time you had to tinker with it? I'm getting ready to go on a trip - the guy watching my tank is a newbie and I'm trying to decide if I need to have him check on it (he's feeling a little overloaded with too much information already).
 
Has any one done a verticle mount for the motor yet where the drive shaft is oriented horizontally. Purpose to get the Mod output moving in a cone pattern instead of just back and forth. Seems like this method may be lest obtrusive and potentially lest load on the motor. The pivit point I understand in fact there are 3. The connection at the motor, a point between the motor and the connection to the powerhead and at the powerhead itself.
 
Yes, I believe I mentioned it on page 4. If the powerhead is somehow counterbalanced on the swingarm, and the pivot is hinged as well, it works fine... but you need to have it perfectly counterbalanced of the load goes directly to the timing motor. The counterbalancing part can be kinda bulky though.
 
Everyone I would like to say this is a great mod. Thanks for posting it. I'm in the planning process to start a 100G tall in my home. Looks like I'll be building a few things first;)

Hahnmeister, yes I saw that. And the one you completed without a box. I didn't see one mounted where the motor turns the verticle axis.

It seem that if the pivit point that actually holds the MJ were closer to the shroud then the motor itself would be the counter balance. Heck if you keyed a piece of acrylic then the pivit point could be adjusted once in operation. I was thinking 2 links from a plastic chain would be a good enough pivit point to actually hold the MJ to the mount. The mount being a magnet with an L bracket which the MJ would hang from.

Also when I was looking at this I'm assuming one could achieve about a 20-40 degree cone without much difficulty.

What would you recommend as the arm that extends from the cam on the motor down to the MJ. Would Carbon Fiber be good enough?? I'm thinking about the size of a Behman carbon arrow.

Thanks,
Dan
 
Ohhh, you are talking about having the MJ hanging from the swing arm, eh?

Maybe a pic would be a good idea. Can you make a diagram or pic so I can get a better idea? Ill make a diagram of mine as well so you can see why I suggest a counterbalance.
 
I think i'm going to give up on the vertical swing. I'm haveing problems compensating for the 2 arcs your dealing with. You said you have one built like that already? I have a diagram in power point not sure how to post it here.

Very little resistance from a mirror ball. We used one at dances and I don't recall the available torque being very strong. Speed is probably about right but not sure about torque.

Couldn't hurt to try. Let us know if it works.

BTW, I love this thread.

Agreed, awesome thread. This and the MJ mod both rock.

I pointed two MJ 1200 Mods at each other (one on a 90 degree swirler stien but soon to be both) and the tank gets a great random flow. The random eddy currents travel down maybe 20" in my 65.

I would add a third to a 92gallon corner tank if you are keeping SPS though.
 
The sound is negligable relative to the external water pump, 9inch fan (in stand), and other sounds on my tank. My swirler stein is identical to the one posted by hmott at the beginning of this thread.

When I first set it up a few weeks ago the PVC (not the motor) squeaked as it turned. I put a few drops of olive oil on the PVC where it touches the bottom of the hobby box and the noise went away.

I just purchased the 3rpm motor and will be installing it on my other MJ mod that is currently stationary at the other end of the tank.
 
Funny you mentioned the squeaking.
My setup didn't make any noise except for the motor for the first few weeks.
Recently my linkage has started to squeak, so I'll have to try out the olive oil trick.

i love a good DIY as much as the next guy but at this point (poor a$$ student) im not so much into "experimentation" with questionable equipment. i think ill just go with a tested and reliable motor from the get-go. that way im only taking 1 0r 2 days away from school work instead of 3-4. ;)
i looked at grainger the other day and all their motors are way to fast or expensive. im seeing a trend with the surplus motors.
great thread guys, cant wait to get my MJ streams and these babies up and running!

Here is my rendering to this most excellent (Bill & Ted anyone?) DIY. I would like to thank Jason, Scott, and Ryan and of course, my wife, God and the academy for helping me put this together. There are a few little bugs that I'd like to work on, but I think that it's a pretty cool little contraption.

I built the box/motor just like JasonJones did, but I wanted to put my 6100 on the end of it instead of a modded mj. Well, I couldn't figure out a way to do it, but then I looked on the wavy sea website and they have a little tunze box that the pump rests in and off you go. Well, these were $25 a pop, which would have doubled this DIY, plus, it's just an acrylic box with a hanger, how difficult could it be? Well, not too bad, as I had the acrylic lying around and some weld-on. Take a few measurements, and boo-ya, I'm done.

Here are some pics of the box and hanger that I made. This fits onto the end of the union and rotates. The screws were tapped into the acrylic, but I don't think that I'll need them since the tunze is pretty well secure.

I added the tunze, and here is the rotation that I get. I think that's it's about perfect for the corner that my tunze are located in. It's still a little off set (kilter?), but that's not too big of an issue.

Start

Finish

And here is how it is attached to my trim. I took 2 pieces of 1x2 and screwed them together to make a 90, this rests on top of the trim. It has a little tendency to pull off, but not much.

So far, I can only have the tunze up to about 40%, but as I get more comfortable with it, I'll crank it up.
