Russian Rocketboat OSA II

[He Who Shall Not Be Named]

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!

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.

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.

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.

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.

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.

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.

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.

Great work Manfred.

Good to see you are still active and Manfredizing again!

[MFR1964]

Thanks Guys, i'm Always goofing around inside the Cave, and yes Tom, the magic still works, it was a bit of a setback with the turrets but i'm finalising them now, as promised i took some pics of all the lights onboard the OSA,




The upperstructure placed with working navlights, i wonder if it's possible to add a toplight, have to think about that



And also some turret stuff, here i've made a new conical shaped base with the right angle, used 0,3 mm copper sheeting, it is placed down the grit for placing those reinforcement rods at the background, this fun took me most of the time, but on the end it's worth it.


Manfred.

[MFR1964]

Placed those reinforcement rods onto the conical part, secured them with CA glue.



According to my real life pics the rods where way too high, cutted them down with the cuttingdisk on my dremel.



Dryfitting on the bow, also added a pvc ring underneath for the next step.



This is why i added the pvc ring, more reinforcement plates at the base.



The front of the conical base is different, this is the start of another contraption at the front.



Since i was building two turrets i could start with the second one while the other one was drying, this one has a higher base, yet again used pvc tubing.


Manfred.

[MFR1964]

The basic form of the front turret is ready, on the background number two in the making.



All reinforcement strips are placed, also the different strips at the front.



Cutting styrene for the next stage on the second turret.



Glued down the pvc ring and started with building up the reinforcement ribs, those small cutted pieces of styrene are made into their final shape before glueing them onto the ribs, still had to make the lower row.



Clipped down the ribs and shaped the little plates, ready for another session of glueing.


Manfred.

[MFR1964]

It was a well spent summer, i still needed to make more parts.



Heaps of base plates.



Inserting 1 mm copper rods.



The second mount finished with reinforcement plates.



Dryfitting the front turret, it was a good decision to start from scratch, much more scale as the old one.



Those parts are needed for this, at the back of the turrets there are railings, those are the mounts from the upper railing, still had to add the mounts for the lower railing.


Manfred.

[MFR1964]

First i fixed my last post, the pics went gone, next batch



Made all four railings, ready to be placed.



Also made this pic to show their size, not that big, but big enough to add a lot of details.



Soldered both railings, a bit tricky with those glued rods.



And finally some primer, now they look totally different.
