Fokker E.V wing color preview .....

[womenfly2]

How does one explain the mirrored reflections on the bottom wing surface showing the strut and control cable, see the center photo of Udet on page 14 of the Windsock Datafile #25 seating in a D.VIII.

The surface almost looks wet?

Dear Jumpinjan, Womenfly2 and others,

Thanks for the technical explanation of why even fully flat surface finishes can still have a high reflective capacity (2?), depending on the surrounding light. I don't pretend to understand it fully but I'll accept it because I am ignorant in such matters.
With this explanation in mind, I sprayed the 1/32 Battle Axe D8 wing (spare)with matte, medium green Tamiya paint on both surfaces. I then placed the wing in a similar orientation to those seen in the Windsock Datafile and observed that the sheen on the upper surface differed very little form that of the lower surface, ie a dull lustre.
In order to acheive the level of shine seen in the photographs, I then sprayed
the lower surface with a semi-gloss varnish. The result was indifferent. When I used a full gloss, there seemed to be more of a similarity to the photos, but even then, still lacked that 'wet' look seen so clearly in Windsock.
Interestingly, a flat enamel coat, when burnished came very close to the desired effect.
So, acknowledging that my little test lacks the required scientific rigour to prove or disprove what the manufacturers used on their aircraft, I'll still try to acheive what I clearly see in the photographs on my model. After all, I've gone through a lot of trouble to replicate those ripples and I'd like to have them clearly visible!

Thanks again gentle people.

Regards,

Dennis

Rig, if you can please update your thread on your build. Would love to see what you have so far.

Cheers.

Which sort of laquer is noted in the parts list of the D VIII-wing? I only have the english translation which is in the Windsock publication: 12,5 kg Oil enamel (prime quality), 8 kg Crown (Krone??) priming varnish. 1kg Ersatz turpentine.

No mention of a laquer made by Cohn, Berlin-Neukölln.

Is there any chance to get a untranslated copy?

And I am wondering why a priming varnish is used when the plywood has to be stained....

Hi Hans:
The listing in the Fok.D.VIII DATAFILE 25, on page 34 is confusing, I do not understand the 12.5 kg (27.5lbs) of oil enamel (prime quality) what could it be used for, there is no color reference.
The 8 lg is obviously kg Crown (brand name) priming varnish. I would assume this is to be used for the interior finish to protect against moisture. Neither of these make sense. I can't believe Peter Grosz made a mistake in translation, he was fluent in German. Peter read letters to me that were in German, and translated them to me in English unhaltingly. This may. The drawing of the E.V wing, I had was from Peter, It was very poor and hard to read. I had sent it back to Peter several years ago. So I can not check the bill of materials. Like you Hans, I am stuck with the Fokker D.VIII DATAFILE.
Blue skies Hans,

Dan-San, I am not a woodworker, my father was. Koloman may describe it far better.

You have to close the wood grain before you can laquer it successfully. Using stains only stains it, the grain is still open.

Priming varnish may be a fillered varnish which speeds up the closing of the grain. Several thinned layers of laquer will do it also, but priming varnish will do that faster. After draying it will need sanding and after that one or two coats of laquer will do the rest.

I am really not sure, but for me it is unusual to use fillered primer on a stained surface. May be Koloman will come to help....

Hallo Hans:
Usually shellac is used to seal the wood surface, I wonder if that is what the priming varnish is?

Womenfly2,

I will certainly take a few photographs of the work so far, all I need to do is master the way to get them onto this web site! Is it Photobucket?

All the best,

Dennis

Hellow Hans , Here is some scans of original drawing . Sorry it is in 4 pieces , because it is too big for A4 scanner .
Not very clear quality ...you can see where the pictures fit together
