HMS Naiad revisited

Post by middle_watch »

He he, cannot keep a Nerd down, I just never know when I am licked!

Image

The keel is doubled up 4mm ply, that gives me the right width for the exposed ridge at the stern undercut, also lots of rigidty, a problem I had with my previous attempt.

Bulkheads are 4mm ply.

The spacing of the bulkheads looks to match the actual bulkheads on the real thing, though I have not measured to confirm. It displays one of the compromises with the Type 12 hull, in order to get it compact they broke the rules, loss of either of the main machinary spaces meant the ship was dead in the water and if either flooded she would sink.

The engine room in particular (between bulkheads 8 and 9 counting from forward) is huge, the boiler room is forward of it. It is here I hit real problems with the hull shape on my previous build so the next step is to add extra bulkheads.

But before I retire back to the scroll saw a look at the focsul, I have extended the keel up to deck level, taking a hint from Ron's Iron Duke and Dave's Rurik among others, but I have extended it the whole width of the raised focsul just in case there are any Icelandic gunboats out there. keel and bulkheads were cross slotted for additional strength.

I have done something similar at the stern, but was restricted by the Variable Depth Sonar Well.

Hi Middle Watch Shaping up well . As they say "you can't keep a good man down" I'm off to a photo survey of the work that needs to be done on poor old HMS Bronnington . The last few days have taken their toll and water is entering the ship from the main deck in ever greater volume .

A very good start Middl-Watch, look forward to your progress, ARH :wave_1: :wave_1: :thumbs_up_1:
Simple but effective.

Hi Dave, it is a shame about the Bronington, I had hoped to be able to help out but work have put me on standby every weekend now through to Easter. Gloom.

The three main machinary spaces (Diesels and Conversion Machinary, Boiler Room and Engine Room) are now split into two.

I need to get the deck on next and some more rigidity. Will probably have to wait until next weekend but I have the Dog Boat to keep me amused evenings. Had hoped to order the plans and look to doing a larger build of the Dog, but the washing machine went cough! Splat! Hum, think I will flood the kitchen now. Will have to put it off for a bit.

The new Naiad looks a much stroger version that the first one. You have made a good start. It's surprising what difference the scroll saw makes, when you ate cutting out lots of frames etc.

Keep up the good work mate. :thumbs_up_1:

It is, but there is a fair amount of wobble on the top of the frames even so, ideally I would have liked to have the keel run up to deck level the whole legnth and cut slots in it and bulkheads for RC gear, but I decided that was too ambitious this first go out.

The main factory is the keel is in one piece, last time I used lengths of batton cut and shaped and glued to form the shape of the keel, hopeless! I had to add an internal skeleton to make the model rigid and even then ended up with a banana shape to the bow that took some serious work to correct.

Thanks Ludwig, I do have to warn any newbies to the site not to use me as a "How To"; tune into the likes of Ron for that. I am more of a "How not to"!

Anyway, call to the boss this morning, cough, sneeze, "don't worry I will be in, just got to wait for the vet to come check out my chickens, they are coughing and sneezing too.... What? Take the day off? Oh, work from home, yeah sure, I can do that, I'll get cracking on that report right away!"

Image

4mm ply deck fitted, check out the transom, the plans show it as part of the other bulkheads, but do not allow for the fact it is angled, so you have to increase the height of it to allow for the angle, with me? The plans show it foreshortened in effect, it threw me out previously and I ended up with a sharp drop in deck level at the stern.

Image

The cutouts for the mortar well, VDS and superstructure have only been roughed out, I will finish them up in situ, simply because I find it easier once the ply is solidly attached and not vibrating and flopping around on the workbench. Also still to do is the ramp section on the focsul.

I could not persuade the ply to follow the camber at the forepeak so I will reinforce that area and screw the ply down to form the camber, this only exists at the very peak of the focsul.

Note for Leanderphiles: the VDS or Variable Depth Sonar was Canadian, the MOD tried to design its own but gave up. There were never enough VDSs purchased and the last Leanders were not even fitted with a VDS well. Use was phased out on all leanders by the late 80's

The VDS was regarded as essential to probe the "shadow zone" formed by sudden changes in ocean temperature at depth, submarines can hide in this layer as normal sonar is deflected away.

The VDS was replaced by helicopter dipping sonars and an increased realiance on passive sonar technology.

Middle Watch your storming ahead Ron and Victorious must have cast their magic spell on you. Joking apart you Leander is progressing . really well and I certainly look forward to your posts :thumbs_up_1: keep em coming!

"Cor, stone me, Shippers! I have heard of freezing the brass balls off a brass monkey, but the VDS? Skipper will do his nut!"

HMS Arethusa in 1985, I think Narvik. The VDS well minus its occupant. Arethusa had a habit of getting frozen in to harbours, she also tended to break down whenever passing close to a port.

Thanks Dave, this scratch building is not easy, but it is immensely satisfying!

My pleasure Middle Watch . As for easy, well it's not ment to be that , frustrating oh yes but it has to be satisfying or it's not worth all the sleepless nights.

Blimey mate, at the rate you are building, you'll have it finished before Iv'e finished the planking :heh: :heh: :heh:

Looking good, keep up the good work, we are all with you on this. :thumbs_up_1: :thumbs_up_1: :thumbs_up_1:

Hi guys, managed to get a few hours in on my ill fated Leander. With the distorted deck largely fixed due to surgery on the bulkheads I felt confident enough to start planking.

Image

I decided to use 1" strips cut from1/8" x 4" sheet

2" strips along the flatter sections.

Working in the wider strips was not easy, but it did make short work of the planking and the hull lines just seemed to jump out at me.

I built up the bows with 1/2" sheet balsa
