i no someone who had a speed controller on a external Quiet one pump never new how that worked. been meaning to look for him and find out how he did that.

Hi all
Sorry I am on a mad one trying to split myself in to as many of me as possible trying to implement everything for the new Tank & have just had no time to post.
I will post up the 3 propeller maker name, as I have not had a chance to look yet.
& I think the fixed shaft pumps are quieter as there is
A. -.- Less play in both 1. the shaft & 2. the mag & housing
B. -.- The prop (as long as centered/balanced) will automatically center it's self
Hahnmiester - re -
For the 802, Frunkster...have you managed to use a stopper or anything to keep the prop spinning in the right direction?
Yes, it seems to work like this
The fixed shaft IE the 802's need to have the stopper within a few 2-4mm of the propeller
The floating shaft ie the Maxie's need to have the stopper further away say 1" or so to work every time IME so far
See my gallery for the stopper & loads of pic's of the mod's, been to see a man with a lathe milling machine & flat CNC who is going to help as a free joint DIY project
I will try to keep up, but I'm snowed under at the mo, tomorrow I have to travel to a tank shut down for kit (200mile round trip & divert off another 30 miles on the way back to source SS shafts from a SS firm) as I can't get them anywhere locally, so keeping on it

Aquaclear 402 flow
Aquaclear 402 flow
OK guys, this is a few pics I snapped of the 402. To give you an idea of the power, the pump is mounted in the back of a 32 inch deep tank. It is about 7 to 8 inches below surface and is pulling a vortex! I only have the great planes 1.5 inch on it. I can't even imagine what the dumas 1.75 or bigger would do, but I will find out! Ha! The third pic is to give you an idea how far back the pump is and still sending ripples out to all sides of the tank, top and bottom! The pump still wants to start in the wrong direction most times, but the stop helps to correct it after a couple of tries. I will just leave them running without a wave maker anyway!

Re: Aquaclear 402 flow
Awesome! So that's an aquaclear 402? Could you take pic of the stop you implemented to make it go the right direction?
Later,

Re: 402 stop
Re: 402 stop
Perfect! Thanks!
How far is the prop allowed to travel before hitting the stop?
I was going to try this mod with a maxijet but seeing that the aquaclears don't require a cross brace and all that I'd like to try an aquaclear.
Did you end up using the RH or LH prop?
Thanks,
Tyler

Here is a couple of pics of stop. It is just a piece of carbon fiber tubing.
Perfect! Thanks!

My gosh, and thats a pretty small prop considering...I cant imagine with a larger prop... smjtkj, can you post how you attached the shroud to the pump? I havent gotten my hands on a 402/802 yet, but I would like to know what to expect to need/how its done.
AC motors can be 2 pole (alternating attraction/repulsion between 2 ends) and 4 pole (yada yada yada, you get it). A cheaper 2 pole has no direction control, unless a manual clutch or brake is used as we are here. A 4 pole motor however, switches not only from back and forth, but in a rotation...so this rotation can be regulated.
FWIW, SEIOs are 4-pole because they must spin the same direction every time (their hybrid prop-impeller is spiraled in one direction). This is what will allow their eventual use on the wavemaker they are coming out with w/o the pump having to be DC. This might work on other pumps, but the danger is that as you get lower and lower on power...it becomes easier and easier for the pump to change direction. With a 4-pole, it will continue to slow until it stops.
As for why the fixed shaft is quieter and easier, etc...well, it eliminates the need to center the shaft like with the MJ mods. the prop doesnt even need to be drilled, and if there is play on the shroud...who cares. While it is possible for the MJ to be just as good, the chance that it wont be perfectly centered is greater. I dont have a problem with noise with either so far (except for startup), but I do notice that the vibrations from the Mj are much greater than the AC.
Long live the AC mod!!! I was going to scratch some pics of the 901 in action in the next few days. A LFS with a 10,000g shark tank said it would be okay for me to use the tank to test the prop. Thats great, because I could use the space...the 901 throws a good 6'+ long cone of water!

I had the left hand props so I used them. The stop is probably like 1/4 inch from the prop. I was considering getting some right hand props to try, but I can't seem to find any larger rh that have a large enough area to drill for the 3/16 tubing. The graupners are only 4mm and don'y look to have enough leff around the hole to drill. So I think I am just going to go with the 1.75 Dumas if I don't make progress on the search.

Just a note to anyone who might be tinkering w/ the idea of creating a HUGE mod: maybe try a stainless steel prop? I think that if exposed to higher flow, SS doesn't corrode nearly as quickly as when crammed in a tight area - ie a screw hole or impeller shaft.
The choices go up a lot with SS, though its expensive. Prather makes one that is 3.1" and a pitch of 4.5" (I'm not sure how to convert that pitch to a standard, it seems out of the oridinary.)
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDS09&P=0
EDIT: I think you just divide the pitch (in inches) by the diameter of the prop, so that one above is like 1.45.

man you like zipties almost as much as i like my superglue ( looking at fingers covered in it 
). mod looks good.
i tried something last night to see if it would quite the MJ down. I glued the shaft in place in the MJ. took out the shaft and filled the hole that i goes in with a little gel. pushed the shaft back in, with the red bushing thing and the rubber around it. then i used the original impeller cover to align the shaft while the glue dries. then assm. as normal with the prop assm. work great and made a lot less noise

iff you look at the original impeller cover you can see that it has a hole right in the center of the thing, to allow water to squirt out when you assm. the unit with the red bushing thing ,in its stock form. i just used this hole to align the SS shaft that i cut to be the length that i needed for my mod.
