Linen color for Voss F.I?

Taz · 14 November 2007, 10:31 PM

Srecko- The photos of the V.4 WN 1661 and V.5/F.I 101/17, WN 1697 before painting clearly show a very light colored linen looking almost white, like a Pfalz Eindecker. I think I even sent you some of those photos. It took Dan-San's comments to make me notice, however, so I owe him a vote of thanks.

Hi Taz- yes you have send me a number of images. As I know the bleached linen look almost white. Problem is as you know the same properties of black and white film and state of coat when it is very fresh.

Cheers

Taz:
The wings and tailplane and rudder were given two coats of clear dope, the fuselage only one coat. From what you guys have come up with, the aniline dye was mixed with the varnish and that was only one coat of dyed varnish?
I sounds a little sparse to me. If you want a comparison check with Alan Toelle about the RFC/RAF and the French did. They were also short of dope.
two coats of dope will not seal fabric. As part of my military occupational spec, (620) Parachute and Fabric Worker. We also were trained to cover and finish airframes. Did not do very much, but did do a few.
Blue skies,

Hey Dan San, Was the fabric and airframe work you did in the military on airborne gliders? What type of glider airframes and/or repairs did you make? This kind of "hands on" experience has a great deal of bearing on what it took to seal linen fabric being stretched over wooden components. Just a thought. Scott

No it was when I was in the Air Transport Command, the Waco at Romulus Michigan, and the C-47s at Dum-Dum Airbase near Calcutta, India. The problem was some of the dirt fields in China and the terrible heat and rain in the mosoon season. A terible place to be in, in service. At Deragon air Base in Assam valley in Northest India we had piece mat runway. Along side the 6500 foot runway was was a 6500 foot long pile of rocks about the sixe of a golf ball, whenever a plane landed or took off the coolies would run out onto the runway and push these rocks into the holes of the steel mats, and raise them back to the surface. It rained 350 inches of rain from May to October, that's over 6inches every day. How about 115 degrees of temperture and 100% humidity!
Blue skies,
Dan-San .

Taz:
I have gone back and read the BLV (Bau=und Lieferungsvorschirften für Militärflugzeuge. Building and Delivery Instructions for miitary Aircraft) and read the doping and painting instruction requirements.
It states in the last sentence of the paragraph:
"After the doping is finished, one more coat of varnish."
I don't know the provence of the Fok.DR.I fabric sample that Alan Toelle inspected, did not have the varnish coat on it, that may well be, but it was there when that Fok.DR.I was accepted by the Bauaufsicht
The 1916 BLV, specified 3 to 4 coats of Cellon (dope), and one coat of varnish and greens and browns coat of camouflage paint and blue under surfaces.
In a USN/RFC document I read regarding dope, stated it was not waterproof by itself, and would require coat of varnish to waterproof the surface.
Varnish does not bond into/with the doped surface, it forms a film over the surface.
Blue skies,
Dan-San

Hi Dan San and others.
I found this article on the homepage of Mr Müller, about the use of Cellon on WWI airplanes and did not want to hold it back. Thought it might fit in this context here: Unsichtbare Flugzeuge

PS:Sorry i didnt know where to put it

regards

Hey Taz! Check your six. . .Thats me. I got your back. You say something I disagree with I'll waggle my wings.

Hi Taz, I'll cover your six as well, your helpful information & photos have inspired me to do the research to make my model as realistic as possible. Only thing keeping me from completing it now is a foot of snow & ice cold temperatures, I have no place available to airbrush inside wher I live so I think it will be a few more months anyway until I can complete it now. Well have a merry Christmas!
