My 1:77 Scale Disney Nautilus Build

[He Who Shall Not Be Named]

Pretty sure that issue is an artifact of the casting process and not in the design of the masters. The tails warped away from each other, spreading that gap. If you look at that section carefully from the side, I bet you’ll see the horizontal lines of the rudder opening are not parallel, but rather angled away from each other. You can fix it by heating both and bringing back to the proper position. Would have saved messing around with the rudder extension, though that is equally viable as a solution.

Trouble is, resin has a memory. You apply heat and stress the structure to the desired shape and hold the pressure till the part cools and it retains the desired shape -- but only as long as the ambient temperature does not rise substantially. However, take it to the lake -- the work sits under the hot summer sun for a few minutes -- and the structure returns to its original (disfigured) shape. The permanent fix is to break/cut off the upper vertical stabilizer (shark-fin), reposition it and bond with a GRP reinforcing at the union.

Hi David!

I thought it might have been I missed something during assembly! But none the less, that bright piece of brass was just glaring at me every time I looked at it! Like you just had to do something with it!:-)

This is really no big deal, but it was something I ran into on stern with the rudder!



I had to add an additional 3/16" of material to the rudder top to fill in a gap between the top of the rudder and the fin attachment! I will shape this piece to make it fit properly!

I had to do the same thing on the two I assembled. No biggie.

Awesome work, Rob. Loving this

Thanks Bob!

Made some additional headway today on the stern mechanics of the Nautilus!



Got universal joint and the dog bone assembly put together, and it lined just perfect. Anyone building this model. make sure to look at Nautilus Drydocks (Bob Martins) build videos. They have been a great help for me in building the Nautilus!

This afternoon I was able to complete another mech. hook up on the Nautilus!



My little 2' X 4' building bench is getting a little crowded! I do envy you guys that have really nice building shops! But I make it work! So enough complaining!

I finished up the rudder control linkage, and the linkage that will control the vertical up and down of the prop shaft. And thanks to David for setting me on tract with the sub driver! Like turning the motor compartment end cap to make it all line up so I got straight shot to my controls! "Thanks David"

I have one more set up to do on the sub driver, and that is the prop shaft hook up system. Straight shot should be a piece of cake!! I want to finish up all the wiring and ballast work on the sub driver. and do a leak test and then the final run up. Then we can go onto the electrical lighting system and the final finish work! Light at the end of the tunnel on this project!! It's been a real fun and challenging project for me, and I have been learning a lot!

Tonight I worked on the rudder control system on my Nautilus! Trial & error procedures here!



Anytime you have a lot of turns and bends, it does take time to get it right! I do have some clean up work and then this portion is complete!

[rwtdiver]

Not at all, sir. My flat forehead is a consequence of one too many palm slaps after just such a 'eureka' moment of stunning brilliance. All to often the answer is as simple as a half turn of something.

David

Thanks David! Sometimes I just push a little to hard to get things done, and then I start messing up! Need to slow it down and think things through totally!

OH MY GOD! How did I miss that! I see now the ballast servo is not part of the motor bulkhead!! David ounce again you come through! If I could only find a place to hide! My apology to Nautilus Drydocks (Bob Martin and David) I really made a BIG XXX of myself this time! Thank you David! Another lesson learned! WOW!

Today I worked on the prop and its installation on to the shaft. I also installed the linkage from the prop adjuster!





This photo shows the prop in a slight upward vertical position which will aide along with the ballast system to achieve diving!



This photo shows the prop in a slight downward position which in turn will aid along with the ballast system to achieve surfacing! Ounce the linkages are cut to size and hooked up to the SD the shaft movement will be some what more enhanced to achieve upward and downward movements!

Rotate the motor-bulkhead 180-degrees.

Fixypoo!...

With considerable amount of fitting and refitting I have the rudder installed and ready to fabricate and tie in the linkage!



I have run into a little problem with the Sub Driver that came with my Nautilus kit! All of the control linkages come from the top of the cylinder! If you use Nautilus Drydocks YouTube build series on this Nautilus you will see the linkages come out of the cylinder from the bottom!



This will certainly make the installation of the rudder control, and the prop power and control system a real challenge! Well people! Welcome to the world of RC submarine building! No Problem! It will certainly require a lot of creative thinking and design work, but somehow I WILL figure out a way to stuff all that mechanism into that small stern area, and have it all wok flawlessly!
