Glad the penny dropped. When the master was scribed about 12 years ago, the reference information wasn't too easy to come by. I think it's the same story for the other gratings too, although I've not seen any pictures of those.
Another piccie-

now I know what I should have looked at at first I thought I had got the shape wrong and was going to have to hit the filler sooo soon  :embarrassed: but then when I sat and studied the picture you posted after about 10 mins I saw your point and the second picture (in my defence if you had posted the second picture first  ok2 ok2) is even clearer.

Thanks again Andy

Stop making excuses- it shows the vents correct on the plan anyway, so there!

ha ha me excuses never  {-)

Had 2 days on the vanguard now got some more pictures of how far I have got not sure whether my control rods will be approved or not but its quite simple and easy to work on with my big hands still got loads to do. In the picture with the WTC in the sub the position is wrong I just put it in there and anyway it saves space, enough of me rambling on now here are a few pics

Nice to see another v class boat taking shape. We will soon be able to have a flotilla of bombers.  Regards sub.

heavy into the drill and lots of needle files being used today think that I only need to pop a few holes in the deck now to let out any traped air when she dives






I have got some nice mesh to fit behind the square vents or whatever they are called

You can drill out the holes for the retractable cleats/bollards for venting. On the OTW hull these are scribed circles about 4mm diameter, on the fullsize boat they're actually teardrop shaped. There are about two dozen along the length of the deck plus another sixteen vent holes on the missile hatch doors. I'd recommend one or two larger holes at the stern, you have quite a bit of choice there, but the two located about three inches forward of the rudder look promising.

Three more pictures of my Vanguard build. First picture is of the rear connections and prop shaft I have chosen to use electrical connectores to hold all the push rods in position



Second picture is the location of the battery, going to be using 12v 2.8Ah as I have a couple of these available the batter will also act as ballast




Third picture is my front dive plane connection utilizing a piece of brass strip to connect the two sides together

I'm hoping that lead acid brick won't undermine the boats stability.

Hmmm it is a bit heavy Andy I haven't got enough room under the WTC for a line of battery could maybe custom make a set for the front and also a set for the rear of the WTC any tips would be really appreciated

You may as well try it out, as you have it. Worse case scenario is the boat is unstable, then you may need to reconsider.

Looks nice. Don't know if you have reference for the casing grills- they should ideally have a horizontal/vertical cross-hatch as opposed to diagonal, and be flush with the hull. Depends on how picky you are about details. You can get brass photoetched grill sheet from EMA's or the 4D modelshop. Ramesh used some on his Typhoon.



Hope you're going to drill some more holes in the deck than that- trapped wind can be embarrassing.

Did you get the link I sent you for the Photobucket Vanguard gallery?

Andy I didnt get the link from you can you reasend it please as to the grill I have used what I had to hand which do the job and look the part I dont know if anyone else will notice that the grill is not the proper item, if any of the rivet counters mention the grills where I sail I will just have to say that the MOD class the grills as top secret and that this is my idea of how they look and  I am still having a problem sourcing  the nuclear reactor so I am going to use an electric motor and batteries for now,  >>:-( <*<

It would have to be someone who knows the boat fairly well to notice, and it would need to be close-up too.

I've resent an invitation to the gallery via photobucket, if that doesn't arrive, then have a look in your spam filter to see if it's got caught in that.

I think Dave means net curtain! Use it as a mask with an airbrush.

I think the prop is silicone bronze- looks like brass, but much stronger stuff. If you do paint it, consider etch priming first. Interesting that Simon has used a heavier alloy for this prop, he used to cast them from aluminium like the shroud.

On the subject of rotors, I watched a program the other night about Rolls Royce, and how they construct their jet engines. They showed some of the construction of the fanjet blades. Made from Titanium in a composite fashion (top secret technique) each blade costs as much as a family car (yikes!!).

Rolls Royce make the propulsors for RN subs, and they base them on fan jet technology, so I think they may use titanium blades for the props. So a dull silver may be more authentic.

Pure conjecture of course- these things are hush hush.

Pickle the rotor in some acid, rinse it off with fresh water, dry it, and squirt it with the base color.

Go to your DIY shop, find a roll or remnant of that plastic window-screen stuff, and use it as a mask as you shoot a slightly darker/lighter color of the base coat. Wa-la: tiles.
