The WSD33 drawings do show the rear turtle deck as having parallel corr., but clear photos seem all to show the rear deck to be 2-piece, split along the fore and aft centerline, with the corr. meeting as a series of "Vees" along that line.

Thanks a lot for that guys. GSPOINTER I know what you mean, thanks. Cheers.

After looking at WS33 I'm not convinced that all Junkers D.I turtle decks were split along the centerline hmmm? My question is:

Did the factory workers treat the corrugated duraluminum sheet as fabric would be treated for the most part?
In other words were any two Junkers D.Is skinned exactly the same?

Nice that Roden gave us this piece in a single part (Makes fixing a whole lot easier)
Still the best D.I in 1/48th scale for the $$$$$ in my book!

I checked all my notes on the turtle decks and all the D.Is are the same. There is a seam in the middle and the corrugations are cut at an angle and meet together at the seam. They are not parallel in the seam.
The corrugations are not treated as fabric, they are part of the airplane's structure. In the wing, there are no wing ribs, the corrugation performs the rigidity in the cordwise direction and transfer the lift forces to the wing spars. Yes, they were all skinned the same.

PS I tried to buy this kit, but my local hobby shop has them all sold out!

So who will be the first to do a resin correction turtle neck????

I was looking over my D.1, and noticed that the prop is backwards. The leading edge is very thin and the trailing edge is really thick. It almost looks like it goes on a pusher type aircraft. Has anyone else noticed this?

Greetings. It seems you are at least partially right. Someone cutting the mold reversed the edge locations but the faces of the paddles are correct. When viewed from the side profile the propeller paddle has a pronounced camber to it. The camber is supposed to curve backward to the last laminations at the rear face.

The fix is to narrow down the thick side (I do this to most kit propellers anyway as they are usually way too thick.) especially at the back side of the boss. The other side is just about scale.

As a side note even Eduard fouled up once on their Albatros D.V/ Va 81xx series. The stub for the propeller mount was placed on what is the face of the prop. So if you followed the kit recommendations it went on backwards. So the camber was reversed.

Interesting note here. On the original aircraft it appears the surface rust inhibitor / primer at least for the interiors of the sheeting was a dark red.

Here is Tom Cleaver's build of this kit.... Roden 1/48 Junkers D.1, by Tom Cleaver

[jumpinjan]

Colors are off. White undersides, pale mossy green & pale mauve and it should be air brushed on (photos don't indicate brushed on). Please no RLM WWII colors.
Check Dan Abbott's color article (WWI Aero) here on this board. I think this model is the short-fuselage production version, not the long-fuse version the author mentions.

Online atleast at some websites there is a debate on this kit and what might be wrong with it. Let me help you set the record. First a little history. Two companies built the Junkers D.I. The Junkers & Co. (Jco) and Junkers - Fokker Werke AG (Jfa). This happened because Idflieg (Miliatry inspection dept for aviation) did not trust Junkers to mass produce his machines. Briefly JFa became the main contractor and the parent company became a license builder of their own design. Curious I know.

1. Concerning the turtledeck.
My sources tell me that initially - Jco turtledecks were centerline 2 part . Jfa one piece (like the kit). After Sept, 1918 they all became centerline 2 piece. Jfa was absorbed by Jco at this time.

2. The walkway plates are absent. These can be added using heat stretched sprue or small .030 thou Plastruct / Evergreen plastic rod.

3. The interior surface of the corrugated metal is not represented. True, but in this case it is probably correct. Evidently there may have been additional plating (1/4 of an inch thick) on the interior side walls and belly of the original aircraft's cockpit area. The contracts for the first 50 D.I (single seat) and CL.I (two-seater) types were titled for ". . .50 Balloon machines. . ." This military designation required the additional plating. And it was the final convince-er for Idflieg to purchase the machines.

If you want to do the interior corrugations back from the cockpit heat stretched sprue could be used here as well.
