Frunkster-


If those propellers you're using have the metal threading inserts, you will want to drill them out otherwise you risk them corroding and contaminating your tank. You wouldn't happen to know the picth of those would you?

D.

Yes they have & yes I've been reading yours & all the other threads related since the beginning (just been held back by stone age mentality & lack of parts here in the UK:mad2: ). If only I could put all those ideas in my head in to reality instantly I would be ok lol

So I took out the brass inserts NOT by drilling (far to messy & risky) - I found a bolt of the same thread size & attached the propeller to it, then held it firmly with vice grips & heated gently on the stove (gas mark 5:lol: ) till the heat transfers to the plastic, then just get a second set of grips to remove the shaft (be quick or you "might" melt the propeller.

No idea about the pitch on the props but I will endeavor to find out for you, next time I go to the shop (if he knows lol)

have you compared the 3 blade prop to the 2 blades?

Frunkster

was your 3 blade prop 1.75"?

If the prop does not come out at all when it starts in reverse, that poses a bad problem. i cant see how a stop will work. that may rule out the 3 blade prop.

Just uploaded lot's of photos to my gallerie, any questions or answes preferably lol for me? please

...

No but I think that as long as the 3 bladed prop is spinning fast enough, it should be able to provide more flow than the 2 bladed one. That's taking in consideration that the pitch is the same in both props though.

good photos thanks. That 802 flow looks looks like a storm at sea.

i want to see your stop.

i think so also. if its the same dia. and pitch. Who makes them?

Ok I'll take 300 of those please

Nice work spazz.

ok just so everyone knows im not making the end caps to sell.
its my friends idea and design. if you want to ask him for some just email him at Ryan@mjmods.com
he set up a specal email for thes mods because so many people are asking about them.

I can't get any of my stopper to work I think it's due to the fact that I'm using 3bladed propellers, does any one have any experience with these?, the flow however is "Mental mental chicken oriental"

I will take some photos & add them to my gallery

i dont see any type of stops in your photos. show what you tried

oops, i hate it when i do that.

The Eheim pump mod will be perfect for very large tanks since the existing intake screen on the pump naturally becomes the perfect shroud. Only two things against the Eheim pumps, the price and the pump size.

well if i can figure out a conversion it would be worth picking up a few used ones to convert over. there cheap if you can find them used. i see them all the time in the clasiffides section here on r/c.
we will see how it goes. i would like to convert my 1260 over to a 3" prop or 2 3" props and see if i can blow my tank up. ha ha ha

 

[Frunkster]

Yourfishman if you see the photo entitled "CS inner housing" & "micro jet" on page 2 of my gallery you can see the stopper in the clear seal & micro jets, & yes it's a bit of a storm in a tea cup scenario in the sump at the mo

The green dot on the mini get is hollow rigid air line tubing which is inserted in the the housing by drilling a hole in the side & inserted the stop, I used the same design with the CS pump but used carbon fiber tent pole for the brace & the stopper, hope you can make them out ok, if not I can do another photo?.

I will find out who produces the props & pitch etc soon as I am able (bear in mind I am in the UK) & I think you are right about the Pitch/More flow than 2 & the maxi being able to turn it.

But bear in mind I have the advantage of extra electrical current on my side, which may be the factor in being able to move the 3 blade props "maybe"?

The Eheim has been modded in the old fashioned hack & slash approach, but works well as does the other 2 I have 1 more 1060 & 1 1260 all running 3 large tanks at a friend home, they have been running like that for well over a year with no issues bar a tad extra noise, no more than the skimmer though :lol:

I will add a few shots of the flow from one of the smaller 1060's in a syrup vat of aprox 130 US gls, you get to see hugly old me in them though so you may ant to avoid lol

 

[ejmeier]

It looks like he just modded the output to give a more dispersed flow pattern - sort of like cutting off the output nozzle on a maxi-jet. If you look closely in the pic, the original impeller is still being used.

I have an eheim 1060 too, and after looking at the shroud, I really doubt it could be resued with the propeller. They are too far foward (would be ahead of or even with prop) and too restirctive IMO.

Yes exactly like cutting off the inlet spout & drilling out the intakes, these don't need propellers as they move lot's & lot's & lot's of water the way they are, the 1060 is easily more powerful that a Tunze 6200 & the 1260 moves about twice that , but I still want to prop mod it:mixed:

It can & will be done soon trust me:strooper:

Yes there is no start up noise & from what I can see (by eye) the prop does not pop out when in reverse (mostly starts in reverse to ), which has me a bit stumped regarding a stopper device, where is Hanhmister when we need him lol

Frunkster
Me and jacmyoung were talking about the 802. thats the one you said one have not figured out how to get it to stop and turn the right way, Right?

You are correct, but I have only been at is for a few day's & not tried a stopper (I'm not convinced they push out like the Maxie's do) & have as such not yet started to experiment with a stop device, I'm expecting to have to come up with some kind of one way braking system, how is another matter :lol:

Ps photos of the Eheim parts strip down added to gallery

 

[hahnmeister]

Huh, Aquaclear mods? What, someone say Hahnmeister?

I still have the smallest. That Aquaclear 10 modded one is only 2.5" long with the shroud, by 1.5" wide and 2" tall...lol...the shoud is only 1" long but plenty for 400+gph.

I just use a piece of rigid airline that sticks into the shroud just above where the prop spins...if it goes the wrong direction, it lifts just enough to cause friction on the prop and make it stop.

 

[hahnmeister]

The only problem with eheims that I see is that they have the shaft supported at both ends. At that, the Aquaclears end up being easier, and that 901/110 is just as big as an eheim 1262 in its output.

Yea he's here he's here! . :lol:

thats easy enough. so the prop only has to come out a little bit. so about 1mm. Hahn does your 802 2 blade prop come out any futher than that when its in reverse without the stop?

the big benifit to the eheim mod qwould be the masive amount of watter it would push with a 3" prop. and if that didnt over load the motor i would just keep increasing the size until it reached the max wattage of the pump. i think we could get it to push 10,000g an hour at that wattage. its an experment for big tanks. not small ones. i knw a couple of guys with 1500g+ tanks that wouldnt mind if i threw it in there for testing.
