K, here we go everyone. This is going to be short as the final portion is fairly simple.
First off, just want to let everyone know the Gel Super Glue is holding up awsome. I had to shorten the shaft on the propellor assembly and it actually broke off part of the shaft on the black portion of the shaft.
Anyway, this final portion is two fold. First to address the problem with the propellor spinning in the wrong direction, second is to change the one thing that was weak on the last design, the shaft stabalizer that go's across the center of the tube and holds the shaft centered.
This picture is where I am getting the tube ready for the new stabalizer. The plan here is to use the 1/4 in tube I already have. This thing once in place will be solid. Remeber to drill the hole as close to the end as possible, also make sure to drill it exactly on the other side. This was easy becasue of the ridges on the outside of the pvc tube.
sorry this on eis alittle blurry, but here is what we have, this is the stabalizer, WITH 2 holes, one in the center for the shaft, and the second is to stop the propellor when it is going backwards. I glued a very short piece of the 316 SS in the second hole. Basicly what happens, is when the propellor spins correctly, the force of the water pushes the propellor just below the SS stop. If it spins the wrong direction, it pulls the shaft out, hitting the stop, then correcting itself. After I finished this, i unplugged and replugged many times and it works like a charm.
And this is the stablizer in place. Everything else is the same as before except the shaft has to be shortened to make up for the new placement of the stabalizer.
That is pretty much it. There is still one thing I do not like, it still siphons water from time to time, sucking in air with it which causes micro bubbles. I supose I can make something to cover the top holes to prevent the suction from the top. I may also go with a slightly smaller tube for the stabalizer but honestly there is no need other that for looks. But all in all, I am very happy with the results.
I am going to be making a few more of these so I will get actuall lengths on things like shaft and propeller assembly posted later. If there are any other questions I will be more than happy to answer. Thanks and God bless.
