Title: Commandant l'Herminier-French light corvette class-1/100
Post by: midori gaoka on January 01, 2018, 11:13:14 PM

Happy new year and Bonne année.


I 've choosen to build the "commandant l'Herminier" because one of my friend had be above his conscription at the end of the eightees on this boat . And few days ago, he gave me a challenge to complete it in a year.
Having make the small frigate "Prairial" at the scale 1/100 in 2003, I've never build another warship till "Commandant l'herminier".
The D'Estienne d'Orves-class, also known as the A69 type avisos, mainly designed for coastal anti-submarine defence, but are also available for high sea escort missions ( in support missions with the submarine boomer).
 I can give you some indications :displacement 1250 t, lenght 260 ft, beam 34 ft and draught 17 ft.
photos of the beginning are coming

Hello,


I'm cutting out the frames.  As you can see I'm trying to empty them as much as I can. In fact the width is just 8 cm, so there is not much space to install motors, rudders, ect...

Bonne annee Midori!

I was looking at French WW2 warships in a Janes book last night and wondered about building one! So seeing this interesting project start is interesting.

I wish you well with your build and look forward to months of progress and pictures. You have a challenge fitting electrical 'gubbins' in that small a space, but there lots of miniaturised electrical components and power packs as well as powerful but small brushless motors, so I am sure it will all work out well. If you can do without power distribution systems you will save space. M-troniks ESCs and Mixers are quite small.

Hello!

Where did you get plans ..... From "Bateau Modèle" ? There is her sistership "Commandant de Pimodan F787"

Hello,
I get the old plan (1982) from M.R.B magazine.
After the frames cutting, it was time to prepare my work-plan
I have of to adapt my work plan in various deck of the model. There are three decks and the front one is an oblique .
I stuck  poplar slats of various thicknesses to follow at best the frames.

Post by: midori gaoka on January 07, 2018, 12:45:10 PM

Hello everybody,
As you can see, there are staples on slats. I remove them when glue is dry .
I Wonder which kind of motorization I'll use on the model ?
Too often in France, we see trawlers or warships sailing as running boat. I think the best solution is a reducted motor but which one ?

Hello,
Thank you for your advices, but which type of small brushless do I need and which kind of speed controler ?
The hull is totally covered with wooden slats. It is now necessary to sand her with some sandpaper of various grains. Some small retouchs of putty will allow a plane surface.

Good evening,
Thank you for your advices. I've ordered 2 small motors. I'll develop it on a next post.
So , now I'm working on the submarine detection sonar. At first, I've cut it in a wooden block. In a second time i've made a plaster mold.
At the end, I've used lead to represent it. It will low the center of gravity.
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: ballastanksian on January 15, 2018, 08:42:04 PM
I hope the hot lead didn't scald you at all  {:-{ Those dimples suggest there was a little moisture in the plaster. Its a nice shape.
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: midori gaoka on January 20, 2018, 12:03:51 PM

Hello,
At first, you are right , I think the plaster mold was not dry enough.

The hull is going to be covered of one glass fabrics of 20 g / cm2. I am going to spread some epoxy resin with a brush. At the end of 4 hours, the set is dry. But on the other hand the brush will not no to be reused, too difficult to wash
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: ballastanksian on January 21, 2018, 08:32:39 PM
That looks neatly done Midori  :-)) I read recently that you have to be careful when sanding the finer grades of Glass cloths as you can sand right through them  {:-{

Brushes can be cleaned in acetone or cellulose thinners unless the brush was cheapy in which case it would not be worth it for the mess caused!

Post by: midori gaoka on January 27, 2018, 06:48:33 PM

Hello,
Resin and fibberglass are dry. It's time to cut them in order to be at the same level to decks. As you can see on last photo,I had to correct the shape of the front hull.So I add  putty to reduce curvature radius.

Hello,
The model is running.The chairs of propeller shafts are put. I am going to position them on the propeller shaft, then to weld them. At the same time, I take advantage of it to realize the rudder.
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: ballastanksian on February 05, 2018, 08:44:00 PM
Does your rudder represent the one where a section pivots to increase the effect of the rudder? I cannot think what its name is. I know fishing boats often have Y-Tails made by welding angle iron to the after edge of the rudder, but this is more technologimacal.

She's looking splendid Midori  :-))

I think you perhaps have Schilling and Becker type rudders in mind?  This looks allot more like a Mariner type rudder of sorts set-up to me.


...'tis looking good!

Hello,
And thank you for your comments.
I still working  on the wheelhouse's roof. Many details to represent but with the grey colour's I don't know if  it would be good.
It's the beginning of the funnel in the same time.

Hello,
After a long break, I 'm back on my model. It was a little bit boring and difficult to complete the funnel so I've decided to work on the back roof.

Funnels phase me Midori. I like the round ones, but the funny shaped ones mm, I suppose it is down to planning and getting stuck in.

Yes, the Exocet launcher boxes are a challenge to get just right. I did some diddy ones years back for a client, and the ribs took some getting parallel. They look good Midori  :-))

Hello,
At first, thank you for your comments.
Now, MM38 exocet launchers are nearly completed. Paint is missing, I'll scheduled it in next weeks.
I've started an anti-submarine rocket launcher for small deep, old technology and not sure it was very efficicient.
 I'll post some photos next week.

How many of us would put flat bars around our weapons mount and be really happy they are equally spaced and more so if they are level! Those semi-circular cut outs are really neat and add so much to the build. Lovely work as well on yet more brasswork  %%   :-)) :-))

I'd hate to be the one on the structure above the funnel if they were at sea, not least due to the fumes from the funnel, and how greasy / filthy did it get. In awe at the detail.

Hello,
I've just worked on liferaft. I did not succeed in mould and resin. So I put each one in my drill and shape it with sand paper.
They are 8 the same number as  counter measure box. They are stocked  inside

Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: RST on February 07, 2019, 10:18:43 PM
Hi,


Just asking -for the liferaft cannisters did you wrap polystyrene strip round the body?  I never had a problem doing this for years but recently I am finding the polystyrene strip breaks instantly as the solvent is applied.  I have maybe been making polystyrene things for 20 years and never had a problem, but the last 6 months it seems to make no difference what solvent or polystyrene sheet / extrusions I use, everything goes "ping" and breaks when solvent is applied under bending.  I am also finding the same chemical attack when I use CA instead -it never used to happen.  Perhaps the chemical mixes have changed?  Much respect to folk (and you!!!) who can still make it work.


Thanks,

Rich

Post by: NickelBelter on February 08, 2019, 03:36:47 AM
I have had that issue with CA, I suspect it's the glue causing the plastic to go brittle while its stressed from bending around a curved form.  Have not had that issue using Tamyia solvent cement. 
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: Niall on February 10, 2019, 02:24:58 PM
Could I suggest rapping the plastic strip around a suitable diameter metal rod(I usually used the shaft of a drill bit). Tape in place and pour over boiling water. The heat forms the plastic to the curve and reduces the chance of breaking when glueing in place.
Title: Re: Commandant l'Herminier-French light corvette class-1/100
Post by: RST on February 10, 2019, 06:19:06 PM
With the greatest of respects, I'm intrigued how our modeller does it.  I'm not inexperienced, actually I tried the Tamia solvent for the first time recently and I find it the most difficult solvent to deal with -it's very aggressive, clearly designed for plastic model kits.  I'm in France these days also so no easy access to the usual solvents and glues that "just work" over the last 20 years.
