DIY MaxiJet Stream (Pic Intense)

[dhnguyen]

smooth enough that I can't feel any resistance when I spin the impeller on it. It is as strong as stainless steel I would think and much lighter.

No welding rods needed. It's much simpler than that. I built a custom BMX bike and I know that 14 gauge Ti rods are used to make light bicycle spokes.

.

Great idea! One would have to be careful to get a round one I would imagine, not blade or the kind that gets narrow in the center (forgot the term).

Straight spokes are uniformly round. I've never seen flat Ti spokes or Ti double-butted (narrow in the center).

Would anyone know has made one of these be willing to send me the prop assembled and the carbon fiber rods. I have the pump, the magnet and the PVC parts, I just dont have rods or props, or the time to put it together. If so let me know how much.

Thanks

Well all, I have started getting my parts together and am having trouble getting them at the LHS. There's only 2 that are local and i'm checking the other today after work. Anyone get their parts online from a hobby shop? If so please post a link for me.
Peace out!

Well, I found everything I needed at the other LHS. I'm going to try out some carbon fiber for the rod. Sofar everythings going together really well. Wish me luck.

Another option for a Rod would be to check into the cost and availability of a Ceramic coated rod or a solid ceramic rod. they will not corrode, are more durable than carbon fiber and will be the last surviving part of the Mod

Aside from that, I might also look into adding another prop down the shaft at a lower pitch. that should help with cavitation

 

[dhnguyen]

Ceramic rods are not easily available, they are not available in all OD sizes, nor are they cheap (something like $11 for one at last I checked for a rod of 6 inches in length). In fact it is much more fragile than carbon fiber, it will break very easily whereas carbon fiber will not.

Well ladies and germs, somethings not right. I made the mod and put it on my MJ1200 and i got **** for flow. Its spinning correctly and i can even get it to draw air from a couple of inches below water but the flow is too far out to the sides. Instead of the flow being directly from the front-center of the PVC, its so far out to the front-sides of the PVC that only if you put your hand to the edge of the Output will you feel any flow. I thought I might have the prop on backward so I flipped it and I definatley have the prop on correctly. I'm thinking about going back to the LHS and getting a 3 blade prop I saw. Maby that will fix the problem. Anyone else have some sage advice for me?

Oh and BTW, Carbon fiber is fun!

 

[melev]

Do you have the intake holes in the correct area? Can you post a picture of what you've built?

 

[Fuegofish777]

Definitely sounds like you

A. Don't have enough holes for the water to be drawn in or that they are in the wrong places. Could even be that the holes are too small even.

B. Your prop is too large for the pump? What size is it?

Any photo of the housing?

D.

 

[bshumake]

The prop i'm using is the hammer craft that this mod calls for.

The holes are 5?16 for the larger and a little less than 1/4 for the smaller

Hey there,

Followed a little bit of this thread and printed out the first page parts/instructions. Great stuff and looks like a lot of fun to make!

Is there any recommended additions/changes since the first post based on this parts list?

1 1.25" Adapter SCH4 (Lowes $0.96)
1 1.5" PVC Test Cap (Lowes $0.84)
1 3/32nd 12inch Aluminum Rod (Local Hobby Shop $0.60)
1 Bag of flat plastic washers (Local Hobby Shop $1.20)
1 Bag of Propellers, Aquacraft Hammer model (Local Hobby Shop $4.99)
1 Bag of 5/16 round tubing (Local Hobby Shop $4.25)
1 Bag of 1/4 round tubing (Local Hobby Shop $4.00)

Secondly, has anyone thought of marrying this mod with the mod on this thread or not really feasible?

Thanks! Look forward to doing some shopping.

Yes. Use 0.098" OD carbon fiber rods instead of the aluminum.

I don't think you have enough holes or perhaps the smaller ones need to be much larger. That alone might still not be enough.

Here's how I did mine

Thanks dhnguyen Much appreciated. I have a hobby town USA, Home Depot, Lowes and some HS, I should be able to find what I am looking for!

I am going to try this with an old 400 that I have laying around. Depending on how well I do, I will move up to the 1200s I have.

Question for dhnguyen:

In one of your post, I think page 13 or so. you made mention of making a stopper so that the blade starts up the right way. You noted the little black rod. Is that the small .098 carbo rod? Or something different.

Thanks!
