Hello everybody,
It is the moment to build the tank. The boat will have to sink of 1.5 cms. The calculations watch that is needed a ballaste of 1.5 liters. This one possesses 2 partitions inside to limit movement of the water. A 12 v pump can fill up the tank in 40 s, this is not to bad.6 pipes standing  outside avoid exploding the ballast tank during the filling

I like your engine mount Midori. That is a good idea  :-))

Hello ,
I've made a break on mechanism step. I'm back on détails. I'm working on the top. This is one is made with 0.5 mm plasticard. Supports on side are in 0.5 mm rod brass. They supports cover against sun

Midori.......I am well reminded of your previous superbly detailed large and functional ferry build :-))

So just a few preliminary questions from what we see on you ballast system

1. a requirement of 1.5 litre's of ballast
2. the ballast tank which appears to be located with the tank top near to deck level
3. a tank top snorkel
4. two overboard tank discharge lines located just under the tank top lid
5. two 1/2 width tank baffle plates

a. when you pump/press up the ballast tank, will you have valving to stop ballast water from discharging backwards through the pump/ballast water suction line?
b. how will you de-ballast the tank?
c. with the 2 overboard discharge lines located just under the tank-top lid  will allow the tank footprint to be a full volume of air and hence the snorkel will never function. Without internal dropper leg spools, I am unsure of the function for these overboard discharge
d. fully blocked internal baffle plates with a series of water passage holes across the base line of each baffle plate would slow and help overcome any movement of water [due to any air pocket] in the tank during rolling and or pitching

Looking forward to build progress and detail O0

Hello,
I ll try to answer with my poor English.
a- The ballast has not got any valving system, I switch off the pump when I can see water  getting out pipes.
b- I  can de-ballast  the tank with the same pump by getting  water under the bow
c- The 2 big pipes are used in order to to give the signal that the ballast is full, and  avoid to destroy the tank with a over fill up
d- Maybe,  I've made a mistake witha part blocked internal baffle. But, I think I'll use empty or full ballast not with half fill-up


Bye

Hello,
The wheelhouse is on the way. I did not have any regret to paint piece by piece. It took to much time to use mask tape  before  you paint all
things together in the same time.

Hello,
My answer is very late, as you can see, the inside wheelhouse is not totally finish. There are some light I need to hide.
I 've painted the hull, but for once I 've tryed the weathering method. But it need to be improved  with adding some alguae. If some one has got some tricks to represent it , it could help me.

Hello Everybody,
It is now necessary to take care of the front of the ship. The windlass consists of several plastic part of 0.3 mm. I've  tried to make my own stanchions in 0.3 and 0.5 mm of brass

Your rust streaks are very realistic in not being too dark or hard edged, they feather nicely.

I love the mast and winch, it is all coming along well Midori.

Hello,
I've worked on the front deck in order to add the mast and the windlass. I'm waiting for chains to complete it. In the same time, I'm wondering how to represent alguae on the hull.
More photos are coming.

There are surface products such as Mr Surfacer that Military modellers use to create cast/uneven effects in their models that come in different grades, Then there are weathering powders that can be used to build up similar effects but these are costly especially on a large model.

Also acrylic texturing pastes can be used for this but are usually white so need pre tinting. A tub should do you for at least one model. You can use household emulsion if you get the right colour mixed. A 250Ml testor pot would give you loads of paint.

Interior filler powder is also very good with acrylic paints.

I used to use talcum powder and humbol enamel (Earth) mixed together to create mud effects which is cheaper and more random.

Hello,
Thank you for your advice ,I'll follow it in next days. Now, the mast is completed. In few days, the front deck is close finished.

A beautiful build, very clean and precise. Your weathering is extremely convincing, just the right touch. I am very jealous, it is something  have never mastered! I am anxiously awaiting to see her maiden voyage.

Hello,
Thank you Jonathan for your comments. Now, the mast and windlass are fixed, the next step is the main deck. It will take time to complete it, many pipes and curves..

Well Midori...that green fócsle deck is prototypical......and also for the winches

Not sure if your instructions note this but the machinery shed as you have built houses the electric motors and hydraulic pumps for the anchor and mooring winches, however the main hydraulic oil tank is in the mast O0......for a vessel of this tonnage....500 litre oil header tank capacity would be common

You will also have some mooring winches and valving consoles to create and install

Hello,
The trouble with a tanker's bridge is the number of pipes.It is a succession of pipes, gates and reins. And it is not easy to twist in 90 ° pipes. You always wonder if you follow the good line of pipes, they are so similar. I can admit It is a little bit boring

EMA sell a range of pipes and various angles and 'T's etc if that would help with your labyrinthine project Midori! I am not sure if their pipes go down that small, maybe kit sprue corners would provide a cheap source of bends?

Check out Plastruct (EMA)  http://www.plastruct.co.uk/ they do everything for structural and architectural modelling.   See latest catalogue (PDF)  http://www.plastruct.com/catalog/Vol_10_CatalogSMFL.pdf 

I use loads of their stuff for detail work on my boats.

Pipework can be simulated with various thickness wire, for instance mains electricity cable for wiring homes comes in .5, 1, 1.5 and 2mm thickness if you strip away the insulation from the copper wire - it can be thicker if you leave the plastic insulation in place, but then it is more difficult to get a sharp bend in it. Once painted you will never tell the difference between it and plastic tubing.

A tip for your pipework, draw the pipe runs on a seperate piece of board that can simulate your deck, bend all the pipe on to that diagram and when you are happy with them, its just a case of transferring the pipes to your model deck.

If you look at the weathering paints by Vallejo, AK or Mig, you will find a suitable acrylic algae for weathering, one bottle will cost around 3€ and will be more than enough for your ship. If you want a thicker algal growth you can mix in some of the powder sold for model railways to simulate trackside grass, but that stuff is expensive for a bag full when you will only need a small spoonful. I've seen in the diorama pages on facebook that they also use cooking herbs, that might work if given an overspray of matt clear varnish afterwards.

Your model detail is superb as usual, can't wait for the next update.
