Great work Manfred.

Summer has ended, so building on the OSA is finished, managed to get me some lights and finished up both turrets, had to build both base-parts from scratch, it turned out that the old one's where useless, rebuilding them was not a option, first the lights.



This was the old situation, had made some working bulb-lights, which didn't work that well.



Started with some protection for the new lights, used some 0.8 mm rod and some tubing.



Pushed in a large diameter cool white led, made it frosted by sanding it.



Even lighted by a torch you still can see the led is on, this one is located near the bow.



As you can see there is enough light to navigate during the dark, still have to make some pics with the upperpart placed, to be continued.

Ripped open the OSA for some re-wiring, i wanted to have a seperate battery pack for my receiver, those hatch servo's are pulling too much for the BEC when operating them all at once.



Had to take out the cables to make some new provisions for the new battery-pac, such as, taking out the + lead from the BEC, and rewiring to the powerswitch.



Made a new pack 6 volts 2,4 Ah, should be enough to give me some playtime.



Since i'm going to use a seperate battery pack i have to add a voltmeter for monitoring the receiverpack, found me a nice little LED version, it has two differend settings 4,8 volt or 6 volt.





Progress on the gunturrets is slow, but i'm getting there, added some stuff and finished up the barrels on the front turret, still have to close the part under the barrels with some evergreen plating.

Gunturret time!!, after stuffing up David with the V80 i started up my lathe and made some new barrels.



Compared with the old one, what was i thinking !!!, rubbish the old barrels !!!, on the other hand, now i have much more documentation passed by a russian modelbuilder.



Stage two, both barrels on the turret, still have to modify the inner part which holds the barrels, it has to be square instead of rounded, nitpicking as usual.



The same treadment for the rear gunturret, added also those tube like things at the barrels, not sure what they are, but what the heck!!!, if they are there i duplicate them.



Same story for the front turret, now i have to break down both turrets, sand them, and add some more stuff.

Now i do Chuck, thanks, looks nice but a lot of money for such a small kit, making this kit rc can be done, did the same trick with a Tamiya battleship scale 1/350 in the past.
Now these days we are blessed with those micro servo's and ESC's, so if there are volenteers, be my guest and surprice us, i'll stick to the bigger version.

Thanks Tim,

The antenna stuff turned out better as expected, next year, or maybe sooner, i'll tackle the gun turrets, she deserves to be finished.

Manfred,

You are the master of brasswork!! I Finally got to catch-up on this thread and the work is amazing! I can't wait till next year to see what you do next.

Have you seen Merit International's 1/72 OSA-1 that is slated for imminent release? Shame its not larger scale as it would make a good RC conversion.

As you know time is on my side, so skinning the 23 is eminent, i've build enough strangely shaped subs to know she will drive like the devil on her heels, within certain speedlimits offcourse, i've re-read your thread building the 23 to find the bugg.

Yeah, building things from brass is most rewarding, i've got no idea why i delayed building the mast so long, must have been builders fear, once you get over that, things are starting to roll.

Yeah, Mike's been all over me with PO's. No time on hand yet, but I'm close to securing 'play time' in the Cave so I can catch up. One of the things is to test out your idea about water squirting out those limber holes and flood-drain holes.

Can't wait till you get your 23 into the wet -- want to see if you encounter the same devils I have with this thing. God! ... it's such a lovely kit; and I'm sure it's me and not the design that is making this thing act like an underwater lawn-dart.

Love the intricacy of your brass work -- simply wonderful stuff to look at. Techno-porn of the highest order, sir!

She turned out nice, didn't she, for now party time is over, the to do list is big enough to fill next summer, untill then she has to wait, it going to be XXIII time!, did my remark about your extra floodholes gave some result?, or is your back still being whipped by Mike?

Wow! I hate you!!!

As i mentioned before, summertime is at it's end overhere, last things i've done on the OSA is, finishing up the main radar, and the lockingwire for the upper antenna,



I still had to finish up the mainradar with the receiving part, made the wires with the same method as i did on the radarmast itself, making this radar turn will be the next step, the old geardriven motor i could hear from miles away, so i ordered a new one, which will be less noisy.



Dryfitting the extra radarmast, which is part of the lockingmechanism.



Painted the little antenna mast and rigged it up with the lockingwire, for now this will be the last thing on my summertime project, i'll dust off the XXIII and start building.

Today was interesting, my initial plan was, make the hood, finishing up the job by some paint, i did finished the hood and builded up the construction.
Then it became interesting, i still wanted to remove this construction when under transport, securing it revealed a problem, had to build another antenna mast as a solution, that mast i can remove too, by connecting both constructions with a small wire ( which is also present at the real thing), i can use the new antenna mast as a anchor for my upper construction, pictures



Making the hood wasn't much of a hassle, cutted the failed antenna in half and CA'd it to the hood, added a flagpole as part of my securing system.



This copper baby has to be placed at the upperstructure of my boat, you can see the little cleat (thanks again Myron) on the left side.
The flagpole will get it's wire, which i will secure at the cleat with some CA, when i pull out this antenna mast from the upperstructure i can lift up that structure from the main radarmast, so it will always come off as a pair, which won't be a problem, less problems for loosing the small parts.

Thanks Myron, another word added to my english.



As for being a jeweler, yes, i've got some experience under the belt, made this leaf for my wife, she had a theme party about Lord of the Rings,
those things are not easy to get hold at the web, so i made my own, adding some more skill to me.

David,

You're going to hate me even more, the lathe is spinning now for the last part, have to add some more stuff to the construction and some paint, hope to get this finished this evening.

[He Who Shall Not Be Named]

Manfred! I thoroughly hate you!

Stunning ... stunning work. You and Ron Perrott are the masters of soldering and jig making.
