ICTINCO ll Submarine Build

[redboat219]

The Ictineo has a unique non-counterrotating twin tandem blade propeller ( reminds me of a Gillette razor) .
Both blades are parallel to each other and are separated by a V- shape gap.

The Ictineo only has one hatch, why are there 2 holes on top?

Romel,

Here is the printed part that goes into the space that you were questioning.



There is a small cover plate that will go on as well.

I have decided NOT to cut the hull into a top and bottom configuration.



I am leaving the stern section to be used to house the WTC. I will be using a 2.75" OD acrylic tube for the WTC. I do not need a very large cylinder to house the 550 brushed motor and one Hitec standard servo for the rudder, plus the 7.2 NiMH battery.



The WTC will be secured to the stern section and the entire assembly will slide out with the stern section.

Looking great, Rob!

Thanks Bob! Glade your home safe and sound, and I hope your trip went well!

I am turning my Submarine building to more of a pre-world war l time period. I really like the looks of those boats and their historical value as to their precursor to today's modern boats. Reading the histories of those who designed and built the boats of that period is very interesting as well.

Hi Romel,

I have two photos that may show you why the two holes in top deck of hull!



The large hole in question is located in section "B" and if you look close you will see there is a large insert with a small hatch on the top of that insert!



This photo shows this area in the in the model's half section view!



Here is another view of a model that someone did that shows that small hatch and the structure under it!

Tonight, I finally finished putting the hull sections together using a medium CA.




The above photo shows the HOLLAND, and you can see the similarity in the hulls between HOLLAND and the ICTINEO!

The keel is attached. (Which was a real pain) Next, I will be spending time applying fiberglass and resin to all the seams and joints. I am also going to use some different filler to finish where the keel extended through the hull and to also help shape its final look.

Kinda has that Jules Verne vibe.

I am quite sure that one will work a lot better than the original! Interesting build!
I first learned about the Ictineo II from an article of a german modeller who actually made it in RC from wood! A sort of Super-scale model.

I have started to assemble the hull sections together.





Right now the hull is just taped together to get a feel as to how it will all fit together. It is going to be a challenge, but so far it all seems to be a good fit!

Today I finished up the outer hull sections on the ICTINEO.





I have also made the decision as to the propulsion system (550 brushed motor) with the small Viper ESC and I will be using a 2.4 radio system. The only control on this boat is a rudder and it will be controlled with a standard size Hitec servo. The power will be supplied with a 7.2-volt NiMH battery... This is all predesign at this point and is not set in stone. I also need to start designing the WTC as well!

Rob,


In the future, if you have a challenge like that, hit me up (or post up here and I'm sure someone else will step up). Slicing STL files is a pretty rudimentary thing for a program like Netfabb or many others. Many STL files out there are not optimized for our needs, so a few minutes of playing around can save hours of labor later.


Bob

Hi Bob,

These files on the ICTINEO ll where not supposed to be a full blown submarine anyway, just a cut away. Using Simplify3D I was able to go to MESH and build both half hull sections, so I am slowly but surely learning more about how to manipulate files to achieve the end result.



Not sure what direction I will head to adapt the hull for a WTC, but I will certainly come up with a solution. This is going to be a challenging build for sure, and one REAL robust boat with a 4.5mm wall thickness! :-))
