I have two of these on timers set up on 30 minutes cycles. I have only had them running this way for a few days so it is impossible to make any blanket statements yet. It looks like they will be ok but I will post back in a couple weeks with more info.

Someone may repost them but I think the answers to all your questions are in this thread. I am not trying to be rude, honest, but have you read the whole thread?

EVERY PAGE!

I have short term memory loss... its hard to grasp something like this..

you guys really should make jokes!

and really, how hard is it to type on a computer a few words for each question?

really now!
 
Why not take notes? you know like a little list of all the things you read as you read them. Might help.

Everything is explained on Page 1. I checked. All the pictures were included. And when the original poster logs on and sees your post, he can add the additional information you seek. But as far as I know, it is all there on the first page.
 
Ok I'll humour you on the shopping list.


The materials needed are:

1. 1.25" plastic propellers (Towerhobby.com) either Dumas or Nitro props will work.

2. 0.098" OD carbon fiber rod (Towerhobby.com)

3. 1.5" PVC pipe or 1.5" PVC slip bushing depending on what version you want (Home Depot, Lowes, etc...)

4. 1.5" PVC test cap to be used for the "v.1.0" version using the 1.5" PVC slip bushing (Home Depot, Lowes, etc...)

5. Thick CA (cyano arcylate) glue (towerhobby.com)

6. 1/4" thick acrylic (scrap pieces)

7. Rigid airline tubing (LFS)

8. Flexible airline tubing (LFS)


There are lots of photos and steps throughout the entire thread and you would be doing yourself a dis-service if you didn't read it through from the beginning (there are after all only 13 pages).
 
The only thing I can think of is some sort of "soft" stopper if that makes any since. Maybe something somewhat rigid but coated with rubber or something. Actually with my new stopper my props probably only get 1 to 2 turns in before they hit like 1 sec. so I'm thinking not too much damage should be done...
The things I would be worried about with the "grind" into the cross brace is, 1 wearing out the cross brace and 2 possible jam.

PS my Idea was to use friction to stop the prop from going the wrong direction. IE when the assemble pushes out have the end of the rigid tubing grind on the cross member.
 
Hmmm... Friction would take too long for the whole thing to right itself. What I did was I rounded off all the edges of my acrylic stopper to minimize any propeller damage. But I imagine the same can be done with say a little piece of carbon fiber rod and slip on one of the original MJ rubber end caps.

Yes you will have to drill out the propeller slightly. The hole is just barely smaller than the tubing you need to put it on, so you must drill it out so it will fit snugly on the acrylic tube.

what tools do I need to make the slits???
-- what ever you can. Some people have used a dremel tool, others a drill, others a miter saw. Depends on how you want it to look. Go look how others did it.

how do I attach the PVC to a maxijet 1200?
-- Depends, some have used a pvc test cap, others have made a notch in the pvc. I think the test cap is the easiest if you can find them.

can I use rigid airline tubing for a crossbrace?
-- Its a DIY project, use what ever works.

Like everyone has said 90% of the information is on page 1. The reason the information is spread all over is because there is not one set way to do this. Everyone has done this in a similar way but has used different techniques to do it. If you don't want to read through everyones different styles then just do whats on page one.
 
If you guys want to check out the movement I'm getting from the MJ Stream 900... Click on the red house for the link to my web cam. Right now the only pump on is the MJ stream 900. What you will be looking at.. at the moment is my new Galaxea. The MJ is about 6 to 8 inches about it and behind it about 4 inches. The flow you see in the lower left is comming from the other side of the tank 48" away... My fish love to ride it like the EAC. You will also see its getting indirect flow from the slots.
 
Of cource not their Irish... Finn and Paddy. lol.

Rigid airline tubing -- The only one the LFS sells -- page 1

My LFS doesnt ... I can get it, but it is listed under several sizes in Lees brand

which size is it?

other than that... thank you all for being so patient !

I apprecieate the "extra" work involved in typeing that! haha


Will the 1.25inch Nitros work in the 1200? I thought you said something about using 1.75inch?

how would you attach this propeller and PVC to the maxi?
 
You better make a few of these if your going to use them in this project of yours.. ;)

the rigid airline tubing is 3/16" OD I believe. You can find it at most LFS even Petco and Petsmart.

Yes you can use the 1.25" nitro props on the MJ1200. You CAN use the 1.75" Dumas prop on a MJ1200 as well but you will need to use a larger PVC pipe (2") and figure out a way to attach it onto the MJ. You can use a 1.5" PVC coupling as I'm told that will fit a 1.75" prop also.
