Title: H.M.I. 'Hydro monoplan 1' (Hansa-Brandenburg W.29 - WNW 1:32)
Post by: kkarlsen on January 13, 2020, 02:02:19 AM
Hi, I've decided to continue with the second part of 'The Duellists' Felixstowe kit... the Hansa-Brandenburg W.29.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-120120164512-16102549.jpeg)

(http://www.danskemodelbyggere.dk/forum/gallery/7698-010120172804-160291701.jpeg)

In July 1919 The Royal Danish Navy bought 1 Hansa-Brandenburg W.29 from Hansa- & Brandenburgische Flugzeugwerke Gmbh.

The first year the Danish Navy had the aircraft, it was tested thoroughly and it was found that it in every way exceeded the planes
that had been operated before. When the aircraft was inspected at the Navy aeroplane workshops, it was measured and plans were drawn.
In the following years no fewer than 15 aircraft of the type were built under license, at the shipyard's aeroplane workshops.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-120120164513-16103455.jpeg)

The Licensed aircraft was named H.M.I. 'Hydro-monoplan I,' They were given the numbers 20-30 (No's 21, 22, 23, 24 & 26 were used twice)
They served from 1920 until the last two (20 and 29) were written off due to age in the spring of 1931.

The subject will be No. 25, with the converted exhaust and no armament (the armament was removed to save some weight).
H.M.I.'s were used solely as reconnaissance aircraft, patrolling danish waters. Little Denmark has 8,750 km (5,440 mi) of coastline.

And the Benz Bz. III engine (engines)

(http://www.danskemodelbyggere.dk/forum/gallery/7698-120120143827-160952151.jpeg)

The valve lifters are reworked, adding wire springs on top of the cylinders. Spark plug cables  are made from 0.1 mm lead wire.
Throttle added with spring and mechanism + some additional tubing.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-120120143827-160962048.jpeg)

On the other side the push rods are made from 0.4 mm tubing. Some small handles are added to each of the cylinders.
Some 'pipe' ends were also added.

I found this photo in my archive, showing some sort of transport cart with an engine.
I just have to add this to the build somehow...

The last engine, well lets just say, that I have plans for another build/scratch project
involving a Benz Bz. III 150 HP engine.

Easier to do more engines when your at it...

Hi!
I built two W.29 in my modelling life, the second was heavy modified Japanese version,
so is a subject that I really love.
Choosing danish version is a good choice in my opinion, I love to build models "out of the normal schemes".
Did you see this?

Hi Roberto, it's absolutely useful!
Yes I do know about the 'candy striped' Hansa-Brandenburg W.29.
I'm not sure about background story though.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120113857-16146495.jpeg)

The build is close to the 'paint phase'

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105508-161402289.jpeg)

I have been 'derailed' from the build because I have been working on the transport 'carts'.
The danish are different from those supplied in the kit...

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105507-161342078.jpeg)

Some have wooden wheels...

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120114817-16148346.jpeg)

The earlier ones had 'steel wheels'.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105509-16141713.jpeg)

Originals + cast resin duplicates...

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105509-161421952.jpeg)

One cart assembled...

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105510-161431864.jpeg)

And.. the float fits the cart!

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120105511-16144448.jpeg)

The geometry is about right, the float is not supposed to touch the ground.

PrzemoL:

The 'Polish' profile is found online on Wings Palette, I do not know of it's origin other than that.

Hi there found a little info on the 'candy striped' Hansa-Brandenburg W.29

Apparently "Det Danske Luftfartselskab" (Early Danish Airlines Company) acquired two Hansa's and used them for some kind of 'Baywatch'.
I will try to get to the bottom of this. But there is no doubt, that these are not associated with the Naval Danish HB 29's.
One HB 29 was bought for the Naval station and was given the number 24. It was stricken after an accident 28-6-1924.
The 15 others were build at the Naval Dock Yard in the following years and a couple of them 'survived' and was operated until 1931.

This guy has build another version than the one in the pictures. Wonder if the wing pattern is correct?

(http://www.danskemodelbyggere.dk/forum/gallery/7698-200120113857-161471890.jpeg)

This photo apparently show s the other HB 29 (Or is it before the nose was painted red too?)

Thanks Terri.

Last markings I needed was the numbers.

For this I had help from fellow modeler Thomas Lund, who own's a Silouette cutter.
He drev the numbers from jpg's I send him and voila! masks for the '25' numbers on the Fuselage.

(https://i.imgur.com/EMtyXSl.jpg)

(https://i.imgur.com/4Aywn5H.jpg)

Painted with Vallejo's Stencil color.

(https://i.imgur.com/G4up1e6.jpg)

Same procedure on the big '25' numbers on the bottom wings, painted using Vallejo's Nato black.
And yes they are supposed to be upside down on either wing.

(https://i.imgur.com/fsv3ae4.jpg)

Everything is initially weathered with Flory models dark dirt.

(https://i.imgur.com/C6JOxmM.jpg)

The weathered floats.

Wings have been given a 'light' version of the salt weathering technique, to add some variation to the large grey surfaces.

Next step will be to assemble the build before adding more weathering...

Hi Kent,
until now your build is first class, I really love the carts, about them I have a question: they were "connected" by a bar or free? Only curiosity!
Painted markings added a touch of reality, really well done!

The (one or two?) candy striped W.29 in my informations was or were bought, the one that you are building, as you stated, was built in Denmark.
I don't think that the modeller that built the one with naval lozenge on wings and striped fuselage made a good decision. From photos that you posted,
it seems that, under the wings, there was a "worms camo" or something like that.

Cheers,
Roberto

Wings have been given a 'light' version of the salt weathering technique, to add some variation to the large grey surfaces.

I'm familiar with Salt Weathering, and I think it's usually overdone and unrealistic. However, your "light" version looks amazing, so would you please expound a little?

Thanks,

Hi Gene, unfortunately I didn't take any photos of the 'light' technique.

However I will try to explain what I mean with 'light' using my last project were I used what I would call 'heavy' salt weathering.
I guess that's the one you are familiar with.

I used it to create a very weathered and well used surface on my Coast Guard Catalina...

After painting the basic surface color, which was white on the Catalina, I moistened the surface with water and applied ground salt (important to get different sizes of salt particles). Then several mixture of grey, brownish and dirty white was airbrushed to get the worn look. You can also remove some of the salt and apply it elsewhere to get varied layers.

(http://www.danskemodelbyggere.dk/forum/gallery/7698-170118124820-128861801.jpeg)

And yes it is a mess working with it, but I haven't found any other method that comes close to the results you get this way.
I have even used it on NMF surfaces with similar great result.

Surface after salt weathering technique:

(http://www.danskemodelbyggere.dk/forum/gallery/7698-170118124820-12885304.jpeg)

This kind of weathering would be 'over the top' for most projects...

Now what is it with the 'light' version? Well same technique, with about the same amount of salt applied to the surface.
The difference is to use very diluted paint and a color not too dissimilar to the base color.

(https://i.imgur.com/YhaFys8.jpg)

This will add a 'milky' pattern/texture to the already darkened surface by the Flory dark dirt.

Hope this explains the 'light' a bit?

Cheers: Kent

Kent, after you moisten the surface (I assume you use a spray bottle of water) and apply the salt, do you let the moisture dry before spraying?  Some of the small salt particles must dissolve completely in the water and then gets dried out?  Does this interfere with the painting process?

Sorry, you are absolutely right Ken, I dry the salt/water mixture thoroughly with a hairdryer, leaving no wet spots anywhere.
If it would be wet it would interfere with the 'pattern' you are looking for!
