Nice progress so far Stephen , even though green isn't one of my favorite colours . This shade has a nice feel to it . Would this be moss green ?



As near as I can get it. Yes. My own mix of course.

Looks nice, I notice that its primed in metallic - are you going to use that doing chipping ? - I would imagine, that these crafts would soon show some heavy chipping ?

Yes Jan, This is the method I have developed for all my kits. Metalizer laquer paint as a base. Seal it with clear laquer - dullcotes and then the enamel base coat. You can replicate chipping, oxidizing and wear quite reasonably. Linen covered surfaces are represented by the CDL primer coating and this of course helps me locate and remove all unwanted seams.

Hi Stephen

Great to see your progress and methods on this kit - looking really good so far. Hope to see some more posts on this one soon!

Best Regards

Just finishing up some kit reviews and then back at this. Some progress images to be posted soon.

I think you will find that the wing problem Stephen had was due to nothing more than production tolerances. I had hassles with the fuselage floor that no one else seems to have had. Whereas my wings went together perfectly. You will find that it is only an enclosed space that will vary in size due to changes in air-pressure. In fact, the opposite would happen if the air pressure was the cause, the wing section would expand rather than contract. This is the phenomenon they use to make altimeters work, and airspeed indicators, machmeters, VSIs, IVSIs and many other pitpt-static instruments in aircraft. Did I mention I was originally an Instrument Fitter in the Air Force??

Another quick one, why would you get much chipping on a surface where no one would need to walk? Nothing more than a Mark One eyeball would be used for inspection so where would all the chips come from? I for one would not like to get up on the wing of one os those parked kites as the angle would mean you slipped off everytime!!

The wing would be inspected for buckling of the rivet attachments and stress damage and the top wing was strong enough to sustain the inspection. But the real problem with mild paint chipping comes from motor vibrations translated through the all metal structure during flight.

Nice big model. the wing construction in real plane must to be a hard work, for the early metal construction.

Cheers

Now to continue.


Note the stress break in the bulkhead. Tolerances are a bit tight.

I see the crack, WNW tolerances, I broke my original DVa seat rails trying to ease things into their tight locations.

Sometimes its better to dispose of the locating pegs/pins or whatever you want to call them and set things up by eye it they arent structural of course, easy to say in hindsight.

But it's good to see you fitting time in and working on this again Stephen, how you manage I'll never know, time management has always been an issue with me

Please let me recommend that with this or any build you acquire flush cutting snips.


Here the seat is temporarily installed for a test fit. Still lots of plumbing to install.


Now when it comes to the engine bearers the formers should be lined up correctly and to do this the fuselage should be temporarily united. With the tolerances of the kit parts you can do this with out tape or glue.

Greetings all images to post after midnight tonight. All cockpit parts inplace. NOTE! When it comes to the brass annealing it the best method. Apply candle / cig. lighter heat and bend into position then paint and glue inplace.

Some PE brass requires this at a minimum. But again speaking about WNW tolerances the pilot's seat belt straps must lay absolutely flat when glued in place on the outer sides of the seat. Otherwise you will fight closing up the fuselage.

Here you go.
Firsty the instrument panel with a clear section glued behind it to represent the gauge face glass.


The pilot's left side with some bit of wire to represent cables and the throttle actuation rod.


Here are the pilot's right side shots showing the rudder and elevator cables.

Next I'll finish the gauge faces and a couple of cockpit detail items. Then the engine details and a closing of the fuselage. I am looking at some hinge details for the cowling.

Greetings all,

While in the area lets take a look at the wireless radio / transmitter - receiver. WNW provides 3 parts for this unit. The antenna reel, radio and a pluggin station (molded to the fuselage side wall.

The Company "telefunken" was the powerhouse in WWI that provided many radios "The very first Telefunken customers were the German Army and the Imperial Navy. Telefunken was proud to deliver the first two transmitters for the new coastal radio station, Norddeich Radio, in November 1905. In October 1906, the expansion of a much larger Nauen station was completed with a range of 300 km and HF output of 10 kW. Welcome to the power of Telefunken. "

When a dispute concerning patents arose between the two companies, Kaiser Wilhelm II decided that the two companies were to be joined, creating on 27 May 1903 the company Gesellschaft für drahtlose Telegraphie System Telefunken ("The Company for Wireless Telegraphy Ltd."), and the disputed patents and techniques were invested in it. The name "Transradio" dates back to 1918, when Transradio was founded as a subsidiary of Telefunken.

The type of transradio that WNW has provided appears to be a Siemans Halske.

Small gauge solder comes in handy for representing additional electrical lines.

Here are the results just before I decoides to add some more gauges.
