Thanks again for your interest guys, There's still a fair bit to do, petrol can stowage's,  corvus loading platforms, ships boats, various deck equipment, a whole lot of rigging, and the dreaded 1022 radar to make and motorise, this should keep me busy for a while yet. %%

Well Joe all credit to you my friend she is looking great and look forward to the small ship boats as I have about 16 to get so looking to see what the quality is like, also looking at John Haynes boats too.  :-))

A bit more done, made my version of the Corvus shield/platform, finished the flight deck/netting etc. and finally got round to the AKE 2, so fiddly I made one at a time over two days, glad that's done, now just have to motorise it controllable from the TX.

I had to laugh at the complexity of that radar array and the fact that 1, it is available in etch brass (it is so complex 8) ) and 2, you have assembled it without any warpage or blobs of solder evident.

That is a star elementy of your build so far Joe, now just be careful. Is it more sturdy than it looks, or infact more fragile?

Amazing work as is the spiral staircase and shield.

Hi Joe,

Great progress there. That's one impressive lump of brass, definitely going to be the cherry on the cake when she's at sea with that rotating !!

Thanks guys, the AKE2 is made up with 40 pieces of fine etched brass, the two main elements were built using Cyrano and were then assembled with brass strips and the shaft added using solder paste, by it's nature it is quite fragile, I think even spray painting it will add a bit more strength to the many joints. %% not something I'd want to make every day, but impressive etchings from Scale Warship. :-))

The Double bedstead looks the business Joe.
Good job its only scale size and not weight
as the AKE(2) weighs 4 Tons scale weight would be around 90 Lbs.

You're right there Ned, I was a little concerned about the weight when I ordered the two 965 kits but when they came I could see they were very fine and thin etchings, which makes the assembly very light.  :-))

More like 10 grammes, Ned. You'd divide the mass by 963.

I must have been half asleep earlier I missed that one, just out of interest I weighed it and this is odd it weighs 10 grammes  %%

Finished painting a couple of bits and added to boat, Corvus platforms and petrol can stowages.  :-)

That was a good result Joe! I would have thought the radar would ave weighed more but still, its good that it doesn't as it saves you having to make a clunky mount for it. The AK3 definitly adds some extra finesse to your model. Now that we have a scale weight formula, I am going to look up the formula for scaling speed.

yes I'm always mindful of scale when I go to the lake, with 2" choppy water equating to 16 foot waves,
a bit more pottering done made up the fore mast top out of bits and bobs from the scrap bin, and did a bit on the radar drive, I'm using an adapted mini servo as a motor and just waiting for another mini servo to arrive for the switching gear.  ;)

What ratio is the gearing to? I ask as I am interested because of the size of the radar. Some whiz round, while others bimble around or just oscillate like desk fans.

Looking good as usual Joe:O)

Hi Ian,  the drive wheel on the radar shaft is 20mm dia. made from styrene discs laminated together and fitted with a rubber "tyre" and is driven directly off the splined spigot of the servo which is 5mm dia.  Giving slow steady revolutions of aprox 10 rpm. Which looks about right to me. I'd like to say it was all worked out scientifically, but in fact I've already done a single 965 on my HMS Zulu and that was all worked out by trial and error.  %% %% %)

Joe you are about spot on at 10 r.p.m. for the AKE2 965P is listed as 10rpm in the RN radar and communications Museum
website,  the early AKE1 is 8 or 10 rpm depending on the power supply
Enjoying the build

Thanks for the information Pugwash, that's gratifying to know I was only guessing on what looked about right.  :-)) :-))

The mini servo came today so I was able to finish the radar drive the switch gear and batteries are suspended under the bridge structure, trying to keep C of G as low as possible, now working satisfactorily, I realised I didn't have enough 1:96 ladders so got some from Scale Warship a nice big sheet of etched ladders and companion ways, I made some up and quite like them, although the plan shows vertical ladders I may use a bit of licence and fit the companion ways forward of the funnel and vertical ladders elsewhere, or is this OTT. %%

Phew, well, you are taking your life in your hands making decisions like that! If you have already glued them in place then that is the decision made! If not, then sleep on it for a bit and feel your waters to divine wether you should or not. You have spent long enough in the trade to know which is the better way to get from one deck to another:O)

Thanks for the information about your radar drive unit Joe. I like the idea of using a rubber ring as you have reduced the damage potential to your radar array if it gets caught on something, then hopefully the drive will slip. If you had used cog to cog, it would have wound itsself free destroying your gorgeous brasswork.

I've been giving the companionways some thought and going though all the photos I used to build Coventry, there were companionways fitted in some places, but I'm thinking these were retrofitted most likely to satisfy the latterday Heath and Safety requirements, but I doubt they were fitted in Coventry's time, so I'll be fitting vertical ladders as I've tried to follow the photos and keep her as was, with just a few minor modellers licence liberties. %) %%
