Primorye class

Hello,

I intend to build a primorye class AGI ship. I already have many photos but underwater details (rudders, shafts, hull shape,...) are still missing.
Any help would be welcome!

Thanks and have a nice day

Nico

Tell me he's not Belgian, tell me he's not Belgian, tell me he's not Belgian, he's....

BELGIAN!

Damn, what do these people have with a) the Russian Navy and b) impossible-to-find-reference-about Russian Navy ships???

Russian Navy warships, ok, I can imagine, but now you're looking for spies who are spying on spy ships themselves, sounds like an awefully small chance of finding any of those! :heh:

But ok, I'll see what I can find :big_grin:
Impossible projects are the nicest to accomplish! Welcome to the club btw! So what scale are we looking at, R/C or not?

Yep, from Belgium...
And from the nautical school in Antwerp too... (Well 15 years ago)

About the ship, it'll be a 1/100 RC model. I've started the 3D modeling with a mayakovsky stern trawler reference. A first detail : the trawler has a single shaft and the Primorye has 2 propellers according to the Jane's fighting ship...

Have a nice day

Being dutch (border kid though; grew up 50 km north of Ghent) I have to chip in here. Kronstadt was not too obscure but very hard work in terms of detailing. The Kombrig kit was basically just the right shapes in resin, no detail whatsoever.

This last weekend work : from trawler to AGI. The plans for the hull and the global shapes are ready...

Have a nice day

Hello,

The real work has finally started:
2mm balsa planking on 6mm balsa frames.
Bow and stern part of the keel is made of 2mm styrene.
The yard is a basic pine plank on which plain frames are glued. I intend to remove all those frames afterward, to get a nice empty hull.

Btw, thanks Evgeny!!

Have a nice day

Nico

Hello Nico,

I'm not in school anymore, just forgot to update that for a few years...

I have the plan of a Russian salvage tug based on a trawler hull too. In case you are interested I can still send it. It's called Pamir/Bars class. They're pretty large, I think about 92m or more in length. Perhaps it's still of any use.
When I see your hull I'm pretty sure you're not a beginner!

Hello,

The planking is over and i've added the front and stern block (balsa).
Sanding, sanding...

A thin layer of fiber glass (30g /m�) has been applied on the outside, all frames have then been removed.
Now the hull is empty !
Another layer of fiber glass (Gyproc tape actually) inside.

Have a nice day

Ps, Neptune, i also have a Pamir plan , the one from a french magazine called MRB, is it the same?? Thanks anyway.

No, my plans are of Russian origin. They're not exactly Pamir, they're a closely related class with Yaguar etc. as class members. They're commercial units rather than the military Pamir class. There are a few differences in superstructure and lifeboat arrangements.

Hello,

A couple of putty layer later... The surface becomes better. And the anchor recesses are drilled.

Hello Nico,

what type of putty did you use? It looks very shiny and smooth :heh:

Hello,

Neptune, actually i sprayed a thin layer of white primer on top of a basic car repair epoxy putty, that's why it shines!

Latest work : rudder is ready (a brass core with styrene to build the shape) and its servo has been installed.
I've added a small drain box to collect the unavoidable juice from the sterne tube.

Hi again,

The bridge (1mm styrene ) is cut and glued. Notice that i won't have acces to the rudder anymore, but the servo is still available.

nico,

Very nice job!

I have seen this technique used on small boats a few cm long, but never on a hull this large. It looks like a fiberglass hull!

How flexible are the sides of the hull? Do you have any problems keeping the correct dimensions without any supporting frames?

Hello,
A first level has been built (1mm styrene, always...) and the foredeck is started.

Ps: yes, the sides were a bit flexible before the deck was glued on, but now it's ok.

Have a nice day

Hi Nico This is a great job . This is a system of building I have not as yet had a go at but you have kindled my interest. I know Bill Waldorf uses styrene sheet over timber and achieves excellent results , a method I am familiar with but to build a hull in the method show is different.

Hello,

After a too long period of absence the ship is out of her drawer.
Many holes to drill!
