about your paper plating , what project are you working on ( sorry if I missed something on this very forum ) ?
Ha! Ok, I know I'm a slow builder (or is it just because Ron can produce a hull in three minutes?) and people forget - but it's my Dreadnought: still coming along! I've been working on the plates from keel/bow upwards and backwards, in fits & starts for ages. Taking a break to do other things. But I am getting there - the prop shafts are almost in sight of my paper plates.

Hi all ,

did a little further on on the port "F" strake ...

Image
Image
Image
Image

What's funny about this plating issue , is that all the line I drew on the paper are straight , but as the hull is a kind of non developpable surface , a strake like the "F" one I ended today looks like a wonderful curve , it is really obvious here under :

Image

When I tell that on a riveted hull , 90 percent of the plating is done with straight plates , no one believes me , anyone thinks that plating was done with "banana shaped" plates .

I will have on Zinnia only two or three plates that are "banana shaped" , all the rest is plain straight :big_grin:

When I mean straight , it may also mean trapezoidal or triangular , but always with straight edges ...

And if you don't believe me , I'll proof it during this construction :cool_1: :lol_3: :woo_hoo:

Regards ,

Laurent

Hi Guys ,

sh*t & disaster ...

While on visit by a friend knowing I was building the Zinnia , the guy showed me a book with some pictures of her under Belgian flag , I discovered that the after 4.7 mounting had been removed as the after part of the rounded deck where this 4.7 was put on ...

So , I had to remove this rounded part as well , but as I didn't want to scrap everything , I just modified the boat deck by cutting the rounded part & adding two little pieces on both sides , see pictures below .

How it looked on the real ship :
Image

the boat's deck before the cutting :
Image

the cut has been done & the two little pieces been added :
Image

Starting from the thought that the boat's deck planking had probably completely been redone , I also removed the four portable decks markings I'd drawn before :
Image

To hide the wounds , I just took a piece of brown packaging paper and drew a new planking on it , that piece of paper will be glued on the existing deck ...

the old deck above and the new deck below :
Image

two detail pictures of the new deck , the semi-gloss finish comes from three layer of acrylic varnish , applied from a spray bought in a DIY shop , intended for the automotive industry
Image
Image

I absolutely have no idea when this alteration has been done , but I do prefer this solution , as the base of the after mast shrouds lies now on the boat's deck instead of on the main deck , it is now easier to remove as the deckhouse , mast & shrouds will come in one part :woo_hoo:

I had to wait a little , till the varnish sets , the new deck will be glued on tomorrow & I'll "scotch-brite" the deck to remove the shining ...

Everyone of us had such moments. I remember when I found out that the platforms were flat on the middle deck and I had to mill everything I finished...

Keep on! It looks good and in the end you will remember those steps!

Hi Guys ,

Yesterday & today , I've been busy with almost all hatches & skylights onboard "Zinnia"

From left to right , the Spirit room hatch , the Steering gear room hatch , the little hatch leads to stores under the Wardroom & the assembly in one piece is the Wardroom skylight/hatch & skylight to the shaft alley :
Image

other views :
Image
Image
Image

the hactch leading to the CPO & PO mess is there too :
Image

the breakwater and the hatch to the sailor's mess :
Image
Image
Image

As I have no 2 millimeter punch , I had to do the hatch here above out of metal ...

the two funnels got their conical cap :
Image
Image

the engine room skylight is fitted with hatches either :
Image
Image
Image

The last part I did were the two main trunks to the boiler rooms , they will be covered with grids ...
Image
Image

the front trunk in place :
Image
Image

the front trunk being painted and glued where it ought to :

Looking very nice!
I've said this before, but I'm really impressed by your ability to make such fine + precise parts out of just paper and cardboard.

Thanks for your comments :wave_1:

I just finished the two little skylights on both side of the CO's cabin , they give some light & air to the CPO & PO mess below :

Hi all ,

his evening , I worked further on the plating .

on the port side , all the IN ( sunken ) plates have been glued on , starting from the stern and going to the stem , as the plates overlap each other :
Image
Image
Image
Image
Image
Image

Now , the easier part : the outer plating ( OUT or raised plating ) , here again , starting from the stern to the stem , I've put today on the port side only the "C" strake & the keel strake . the used paper is blue in this case , to show you how & where all those plates go .

At the front of the ship , I stopped it as I will use another colour of paper for the IN & OUT plates ( you'll see that in a few days )
Image
Image
Image


I told you a while ago that on riveted ship construction , 95% of the plates used were just straight , no banana shape , no odd shape either ...

Here is the proof of what I once said , all the plates I used till now on Zinnia are plain straight :

Image

Even glued on the hull , they remain straight :
Image
Image

Here under , I began with the keel strake :

Image
Image
Image

almost reaching the stem :
Image

This is where I had to stop for today :
Image

In the picture below , the laps are well shown :

Image

If you have any question about that plating issue , just ask ...

I just love those riveted hulls :woo_hoo:

Laurent, it looks like you pre-varnished your hull before applying the plates. What are you using to stick them on with, and are there any issues with adhesion?

(And what a pleasure it must be to work on a hull smaller than 7+ feet long!!)

Hi Andy ,

I laid a first coat of cardboard on my hull ( the underlayer you can indeed see , being coloured in yellow ) .

I then drew on this hull where all the plating had to be put ( "A" to "I" strakes , which one were IN , where were the OUT strakes , all the butt laps )

After this , I coated the hull with a polyurethane resin , it's an easy product to use , as it is a one component resin , no need to mix something to it .

The brand I use is "Vosschemie" , the products itself is called "G4"

That resin is originally used in the polyester/fibre glassing industry to coat the wood before lamination with polyester/fibreglass can occur

The inside of the hull also received two coats of "G4" .

the outer side of the hull was then "matted" with a pad of "Scotch-Brite" , to get a rougher surface.

The paper , the plating itself , is glued with white glue , the quality of it being D3 , following an European rule , it just will say that that D3 glue can stand moisture

When the hull is completely covered with the plating , I apply again a coat of "G4" , I "sand/depolish/matt" it again with "Scotch-brite" and it is ready to be paint .

Once painted , I put the hull to its waterline in the bath tub , for a few hours , I never got real problems with my models in the water , it just sometimes happen that a little corner of one of the plates comes loose , I then fix it with CA glue .

I have no experience with another resin , polyester resin has the great disavantage of smelling a lot , while epoxy is a serious threat to the health .

"G4" smells also , but remains bearable , I think it can easily be found by any "plastics" retailer , it costs 17 � for a one litre can .

Regards ,

Laurent

Hi all ,

Thanks for your comments , but this is why we are here for , help each other to progress in one or another way in modelling .

What I've done this afternoon :

I began with the "E" strake , I used therefore green paper , and finished the lower bow on the port side , the starboard side will be done when the full port side is done first .

Image
Image
Image
Image

in the picture below , the merging from two strakes ( white "D" & green "E" ) into one strake ( green "E" ) is good to be observed
Image
Image

a little cut has been done to allow the placing of the plate coming just under :
Image

And here comes the strake "C" at the bow :
Image
Image

Regards ,

Laurent

Hi Guys ,

at last , I ended the whole port side of the hull ...

not much words , just pics :eyebrows:

the remaining of the inner plating still had to be put at the forecastle height :
Image
Image

to get some stiffness , I had to coat paper with "G4" resin before glueing it on the hulll , this for the strakes coming near the decks , you'll understand later why

uncoated paper :
Image

paper having just been coated , resin is still "wet" :
Image
Image

beginning to apply the outer strakes at the deck height , from the stern to the stem again :
Image

I didn't bore the portholes into my hull , I don't like to , so I applied little rounded acetate plastic under the "plates" where the portholes come :
Image

in the picture below , you can see the portholes "shining"
Image

nearing the bow :
Image
Image

This is why I had to impregnate the paper first , as the upcoming plates are glued to the deck with stringers , like in real life , those stringers were L bars , riveted to the deck and the plating . It was one of the most important area of the ship for the hull strength :
Image
Image
Image
Image

further on to the bow, it is completely plated ...
Image
Image
Image
Image


That's all for today , folks

the next step is to coat all the L bars with "G4" and the rest of the hull on the port side , as the whole assembly is still a little weak .

Once the "G4" has set , a little sanding will be needed on the plating and another sanding will happen on the top of the upper plates , to get an even line ...

And as you all have seen , all straight plates , no one "banana" :big_grin:

Regards ,

Laurent

Hi Guys ,

the hull has been fully plated , the paper being coated with G4 resin

What still must happen is putting the two bilge keels and the wooden protection just above the waterline height , as shown on the picture below :
Image

This wooden protection has been put by the Belgians , as there below is the Zinnia at Ostend , but without this protection , this is obviously a older picture , as the after mast rigging modifications were not done already , I have no sources for the era as when those two pics were taken :
Image

back to the model , here some bow shots :
Image
Image
Image
Image
Image

the top of the plating at deck level has been sanded :
Image

the midship area , seen from below , with some sea water intakes , the raised plating surrounding the intakes has yet to come :
Image

the stern part :
Image
Image
Image

I don't know for the moment what material I'll use for the bilge keels , I think they'll be made out of brass or stainless steel , they have to be tough , as it will be a sailing model , paper or cardboard is out of the question ! :big_grin:
