Title: Help with Eindecker engine cowling
Post by: Bluesman on April 24, 2017, 04:10:21 PM
I am going to be starting a Revell 1/72 scale Eindecker. From the pictures I have located online, the cowling seems to be mottled. Were they made from galvanized sheet metal, or was this effect due to some other reason, like paint? I don't have an airbrush yet, but can anyone give me some tips on how to recreate the mottling effect? Any help would be appreciated!

Sam

Good morning Sam,
the strange way the metal Fokker cowling looks is just due the certain polishing procedure at the factory. It is best replicated by painting the cowling in a solid shiny silver color and then adding small irregular squiggles in a contrasting color like silver mixed with a little bit of white using a very fine brush. At least I don't know any other method to replicate that.
Is there a special reason why you go with the Revell Eindecker? It is by far the oldest 1/72 kit of that airplane and I could imagine that you'd be a lot happier with the eduard kit or the brand new Airfix offering.
Best wishes for your project!

As far as my understanding goes, the procedure on the cowling was meant to achieve the contrary effect from polishing - it was meant to reduce the reflections from the shiny metal.

For 1/72 I could imagine a very fine brush, as Borsos said, or mottling with very fine sponge. Polishable metalizers should be the right choice for this, so you can reduce the contrast afterwards by slight polishing.

Cheers

I would imagine the effect could be chieved with a silver ink pen, too.

Mainly because I build 1/72 and it was cheap. I try to get the most kits for my money so I stay in budget. I'd love to build some WnW in 1/48, but cash is in short supply right now.

That's plausible of course. But the Eduard and Airfix offerings are also 1/72 and at least the Airfix kit is a very cheap one too

Nothing against Revell, but this kit is ages old. Just my two cents, I saw pretty builds of the Revell Kit too...

Hi Sam WnW has a "Hints & Tips" section and one of the hints covers this topic:

Thank you, that helps a lot.

The "squiggles" were the result of hand applying an anti-corrosive paste to the metal at Fokker's factory. See Josef Scott's outstanding Fokker Compendium volumes. A soft pencil over a matte aluminum gives good results.

Is this a soft silver artist's pencil you refer to?

No, I used a regular graphite pencil.  A #2 I believe.

An anti-corrosive paste? Is the reference to that in the second volume, I couldn't find it in the first book which is the only one I have (I need to get the second book at some point).

I wonder why they should firstly apply a paste when paint would do the job & secondly apply a paste in such a pattern?

Like many other modellers I assumed the pattern was due to lightly running an abrasive wheel over the metal - variations of such treatment were common on aluminium panels - particularly in car engine bays at the time & for years later.
