Steve,

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

Time to get back on tract!



I have the new stern section printed out, and the top rudder section cut away in order to give more room for the installation of rudders and dive plains linkage systems.

As per the photo you see the new brass sleeves cut and ready to install. This will be coming tomorrow. Right after I unpack my new Arkmodel 1:48 scale German type Vll submarine kit, and the new 80 mm WTC that I will be using to power this sub. This is the new sub and WTC that I ordered from Bob (Nautilus Drydocks) Can't wait!!

Just got word, UPS said I have to wait until tomorrow, Wednesday!!! Weather issues! Another sleepless night!! :-))

No apologies required, sir! I am having this same brain dump as well, and that is why I am on the yellow legal pad now! Geez, it's crap getting old!!!

OH, and what was the first?? I think mine is missing!!!

Decorum prevents further amplification on that, my friend. Yeah. Gett'n old is a *****, but it beats not gett'n older.

I can't remember the first.

Let me guess the first.

Some good ideas here! Thanks Bob and to every else that has chammied in. That's the great thing about 3D Printing in my case, you screw up (which is a process for me) you just download the part to the printer, move on to doing something else while the machine dose the work. and in a few hours, you have another new part to sacrifice (if need be)

AND DAVID! Your work is ALWAYS WELCOME SIR!!!! And stop calling me Ron!! You're giving me a complex!! :-))

Rob

Oh, ****! Sorry, Ron. I did it again! Damn! I don't know where this 'Rob' stuff keeps coming up. My apologies, sir.

Rob (et all),


Since the part is pooched anyway if it doesn't succeed, something you can try is to heat up the linkage shaft to cook off the CA inside. Now, if you don't have a convenient chunk of shaft free to get the tip of a flame on, this can be problematic. I've tried with some success at various points in my career, to use the tip of a soldering iron on the end of the shaft. PLA will soften up a lot faster than the resin parts that I historically tried this on, so no guarantees, but as I said.... the parts are trash anyway. No harm in trying next time!

Amazing work! I mean …your next project, sir . Which sub will you add Torpedo launching system?

We're cluttering up Ron's thread. Recommend you start another thread.

Ramel,

That is certainly a viable solution to the problem, and I thank you for that.



I just remembered a note from the not distant past from our MASTER David M. The use of Vaseline on the shaft ends and inside the brass bushing. I guess it's my time in life to start using a legal pad and writing this stuff down, it sure would have saved me a time costly situation here.

Third time has to be the charm!! We move on and never give up in this hobby till we get it and get it right!!

New stern on it's way! Thank God for 3D Printers!!

Stop whining and get back to work, Fireman!

Normally I would not show off my screw ups! But sometimes lessons learned the hard way should be shared so others do not make the same costly mistakes.





Here is what happened! After hours of prep work installing the bushings in my 3D printed Alfa stern, and then manufacturing the linkage horns on rudders (2) and the dive planes (2) and installing them for the final hook up. I used a very common approach to installing the control surfaces to the linkage rods. Boring a small hole in the control surface and then using thin CA to secure the control surfaces to the linkage shaft.

laying the control surface flat and then putting in one drop of thin CA into the prepared hole. I used a kicker to speed up the process, and thinking the CA had cured, which it did on the surface I pick up the project and went to a vertical position to make sure I had movement! Guess what happened!? Even though the CA had cured at the hole I still had liquid CA on the inside of the shaft that immediately ran down the shaft and into the bushing. Stupid mistake on my part! Well needless to say the control shafts where now glued to the bushings.

Lesson Here: Do not move the control surfaces until you are sure that the CA HAS CURED>

I now have to re-print a new stern section and four control surfaces and start this portion of my build all over again. I hope my lesson will help someone that is using this process on their build.

Geez you guys!

And I am still trying to get a 1:96 Alfa stern section to come together! Talk about an inferiority complex! WOW! I can't even get a set of rudders or dive planes operational! There just is not enough time in life left to do what you masters do!!

Really miss your Alfa sub 6 tube launcher，Sir! Which submarines you would armed with teeth?
