Russian Alfa Class

[SubDude]

It's all down hill from here Rob. Looking good!

[rwtdiver]

Ster section complete!



The stern has been lined up and connected to the main hull! Before anyone gets on me about the current finish on the Alfa. The black and the red is all FILLER, PRIMER, and SEALER that I use on all my 3D printed PLA Boats! Moving On!!

The shaft is installed and is ready to be finished up!



Shaft lined up well to the center point. It is friction free and turns very smooth! Finally got the stern section ready to connect up to the rest of the hull!

Yes, stainless steel washers.

Thank you, David,

Those photos are just what I was looking for. I am fabricating a bulkhead about 2" outside the stern section to make sure things line up!

I have a Question:



I have the oil filled bronze bushing installed.



Is there anything that needs to go between the prop and the bushing? Like a washer?

The prop is now part of the shaft!



Using the correct heat source and heat along with the right flux and solder, it works every time! The prop came out true and lined up perfectly with the shaft.

Next will come the stern section along with the control surfaces and the propeller shaft installed and then the attachment to the hull stern.

I made the decision to solder the prop to the shaft!



After scuffing, and cleaning the interior of the prop, and cleaning the brass sleeve and the shaft itself, adding my flux and using my Dremel torch, we soldered it up! The solder did a good job of sweating into the prop and around the shaft. I am letting it cool naturally and with no water. I think we have it!

I am now getting ready to install a screw (propeller) shaft!



The shaft itself back to the WTC will be 1/8" dia. I cut a brass sleeve that fits inside the propeller, and my thought is to solder the brass sleeve and the shaft into the propeller.

Question: Is there a better way? "SUB" Ed mentioned using a high end epoxy, or would soldering be better?

Common you guys!! I think enough is enough! I would really like to see us get back to building submarines! If we are trying to get more people involved with this hobby, I do not think this is really the way to do it! If this post PO'S some of you, so be it!!

Let me guess the first.

Oh good God.

Update on the Alfa Stern!



The linkages and the control surfaces (rudders and dive planes) work great! The Vaseline trick worked! Now will come the propulsion shaft and pro install.



SIDE NOTE: My Arkmodel 1:48 German Vll arrived today, along with the 80 mm WTC! I purchased it from Bob (Nautilus Drydocks) My plan is to start a build blog on the Nautilus Drydocks forum. I realize there are a few builds of this boat, but I feel it's best to keep them separate because we all have different build styles. My build will not be complicated in the least, but I will be doing a weathering paint scheme on this boat, and it will be in line with the video that Bob has out on how he accomplished his.

Yeah, it's from the movie UP. A Squirrel being a sudden easy distraction to the dogs in the movie. So to is the Type VII. Lol.

Steve,

OK! I got it!

I have managed to get more done on my third attempt on the Alfa stern section.



Photo above shows the bushing installed.



This photo shows the bushing cut to size and glued in. Also, pre-installed shafts to make sure they fit properly and move cleanly with no binding. Now comes the control surface fittings, prior to the dreaded shat glue up!!

Steve,

I guess I will have to draw on my retired Librarian wife to help with "Squirrel" ??
