    Yes, it is a beautiful build, and an interesting cardmodel construction!
    Regarding the slots in the outer wing panels, these are meant to delay stalling of the outer wing in keeping the ailerons effective, and act as fixed slats at a high angle of attack.
    When landing on the decks of an aircraft carrier, one wants to get in as slowly as possible, which leads to the wing acting at a high angle of approach to maintain sufficient lift. If stallingl occurs at approachal, at least the ailerons will have additional airflow resulting effectively because of these slats, therefore maintaining them being effective resulting in the aircraft kept under lateral control. I also do assume, that in very tight turns and possibly on the cost of losing some airspeed, the inside turn wing would also be reaching to higher angles of attack, so also in this aspect these fixed slats could be saving the day.


    The wing panel attachment points are typical for Douglas: the DC-3 Dakota had the same construction (if you look at the 'spanwise' lines you'll notice this aircraft had also 3 spars, making this a very strong wing) and the outer wing panel was bolted with probably 24 bolts to the center panel on L-shaped brackets on the outside surface of the wing. A V-strip covers these bolts for streamlining. This way of constructioning also offers very easy and quick replacement of damaged outer wing panels.

    What a beautiful realistic effect the strips of paper have on the hull representing steelplate reinforcements! The transparant paper as template is indeed a good sulution, I used it on the scratch-built KLM DC-6B, described I think on this forum some time ago.
    I'll be following your thread with great interest.
    Groet.

    Very impressive and beautifully designed!


    Any idea, anyone, about the two little windows in the nose? Maybe they are just landinglights, but then a rectangel shape is unusual.


    I noticed, that the exhaust follows the same "jetpipe" effect as was used in the Convair liners.
    greetings!

    What a great design for a model of a 1950's airliner! I can't wait to download it and start building it.
    I was wondering what the two little windows are in the very nose of the aircraft. Were they meant for a bomber vision, like all Russian airliners used to have in the Cold War era?
    It is also interesting to see how the Iljushin engineers solved the aerodynamic problem of getting as little interference in the airstream between wing and fuselage by designing a large fairing at the leading edge of the wing, resulting in a more or less perpendicular mating of the wing at the underside of the fuselage. I am truly impressed.
    Thanks!

    I would recommend in order to protect this fine model against dust, to spray it first with an inkjet fixative, in Canada you will probably have Krylon Clear. For large unsupported paper area's you must spray very light coats, and I would think 2 or three at the least, with a good drying time in between layers. This is to avoid the blobbing of the paper material. When dry, you can varnish the model with a clear acrylic varnish. Use matt on this stone building. As a result, you will have a model, that you can lightly wipe with a damp cloth to clean it.
    Much succes!

    Ein schönes Modell! Est ist doch schade, das diese Grand Ladies of the Seas nicht mehr da sein. Gelüklich hat die Iniative das Schiff "Rotterdam zu retten gutes Erfolg gehabt. Jetzt liegt diese Lady in Rotterdam!
    O tempora, o mores...

    Ein wunderschone Modell, und es gibt genau die "Gesichtsausdruck" der DC-8 wieder.
    Ich hoffe, das für Privatgebrauch da keine Probleme gibt mit Bezug der Copyrights usw.


    Mit die B 707 von Bob, und die DeHavilland Comet von Lex (auf der Forum Zealots) haben wir jetzt eine richtige Ubersicht der erste Jets aus der 50er Jahre.


    Neben die Frage um KLM Farben habe ich noch eine Vorschlag. Wen es möglich ist, die Schlussnaht nicht am Rumpfunterseite zu stellen, sonst unter die Rahmen, dann kann ich eine Abdruck in SilverPapiere (Red River, aus die USA) machen, und dann die Rumpfunterseite an eine normal Abruck auf weisse Papier von Rumpfobersiete zu kleben, sehe das Beispiel von Cometmodell.


    (Die foto komt später, weil meine pc ein bisschen gecrasht ist mBz My Documents X( )

    I have finished the DC-6B and will make some pictures under the thread "Fun with Models" which I think is in another forum. Meanwhile, to show what the overall effect is of such a large scale (1 : 50) model, and the specific technique of paper panels on balsa, as I showed in previous entries, here are some pictures. They are still raw, I need to adjust lighting and colour in some, bur it will give you an impression.
    Don't hesitate to ask any questions :)
    regards.

    What a beautiful model! Civil ships are really more interesting to look at, and the details of the Johan v. Oldenbarneveld are outstanding, especially the mahogany top of the railings!
    Prachtig, prachtig!

    Scaldis, could you please print the window panes a shade darker, than the light blue you are now using? It would make a more realistic effect, I believe. If you look at photographs, the windows are really quite dark.

    Vielen Dank, René. Ich habe gerade gegoogled und auch eine Englische Lieferant gefunden, mit ungefähr ähnliche preise. Deutlich ist Decalpaper, entweder klar oder weis, teuer, zwischen 2 oder 3 Euro! Na ja, man lebt doch einmal.
    Ich werde einige details geben wenn ich diese Decal machen soll. Ich habe bereits einige Foto's im Thread "Scratch build DC-6B" eingeschlossen. Hier ist eine Abbildung der Entwurf. Im Dc-6B threads werde ich herauslegen wie ich hierzu gekommen bin.
    Grüsse,

    Hallo Kartonisten,
    Für meine DC-6B in 1:50 soll ich spezielle selbstentwurfen Decal machen, die ich in Inktjet Printer will fertigen. Mein eigen Vorrat ist völlig benutzt, also ich brauche neue. Moduni hat nur 10 x 15 cm im Restvorrat, aber keine A-4 klar und weiss. Kann jemand mir ein Lieferer empfehlen?
    Vielen Dank
    Mixbou

    This is going to be a fabulous model!! I will look forward to download it, when available.
    Can you tell us how to print with sufficient accuracy so that the backside print is exactly on the right place? What I mean is, when you cut out the window on the front sife of the print, how will it align correctly with the print on the backside?
    Good luck,
    Mixbou

    Hi everybody,
    I thought I should show you some progress on the DC-6B. As you can see, the fuselage and wings are now fully pannelled and from some distance, it is beginning to look like an aircraft. I have varnished wings and fuselage with water-based parquet high gloss varnish, which is absolutely colourless and somewhat UV-resistant.


    Before attaching the horizontal tailplanes, I must first prepare the KLM colouring, for which I will use normal decals. I have both white and transparant decals, which can be printed on any inktjet printer, a Canon i4500 Pixma in my case, because of the more UV resistant inks it uses.
    In Paint Shop Pro I have painted the blue cheat lines which go under (narrow one) and above (wide one) the cabin windows On the upper cheatline I have inserted the text "The Flying Dutchman" and "De Vliegende Hollander" in light blue, and further I made or scanned the various KLM logo's and registration marks etc. Then I printed this design on a A-4 normal white paper to check if the sizes are correct, by glueing them temporarly with photo (rubber) glue. The effect is already looking like a 1950's KLM airliner, although I am not quite sure of the correct hue for KLM-blue. I am now using blue with RGB-code 24-77-116. I probably will have to try a small piece on actual decal paper and see how it works on the model. If anybody has suggestions for a correct colour-code, I'll be gratefull.
    Bye for now

    The air intakes above and below the nacelle were not much to my liking in the card model, so I modified them, see pictures.
    I added two lips under the air opening in the front by extending two lips which I curved and closed. Further, two narrow v-shaped slits were cut half way the intake, so that they would become slightly more curved. The engine now looks better.
    Next I will show you, how the aircraft looks like up to now.
    Mixbou

    So, let's see how the engines will look like. As I said, I will build them from a copy of a 1956 card model of the KLM Douglas DC-6B, published by EMSCO in The Netherlands. The original scale is 1 : 66 2/3, which I scaled up to 1:50 (130% size increase).
    In the first picture, I noticed the underside of the inside nacelle did not show the bulge covering the main wheels when retracted. So, I slightly extended the shape and made two V-shaped slits. When closing the nacelle, I burnished this part, closed the slits with a little strip of card and got a nice bulging underside. The fit of the other sections of the engine, the middle part and the engine cowling with the curved front inlet is perfect. Again, the cowling and the front opening were burnished to take away the angular shape it would otherwise have.


    Being a copy, the silver colour was reproduced as grey, and the blue colour of the cowling decoration had yellowed with age. Therefore, this needs to be painted in the final stage.


    The propeller needs some more volume in the blade and the hub, so I filled it with heavy card, and cut away a sharp edge to form the trailing edge. To simulate the propeller blade pitch housing, I rolled thin strips around the blade foot. Later I will cover the leading edge with black tissue paper to simulate the rubber de-icing boot. It is not yet visible in the pic's, this will come later.


    The last part will be an overview of the aircraft with wing and engine, to check if the overall impression is good enough.

    Hello everybody,
    I have some more pictures of the progress made sofar.
    First, I started panelling the right wing. To begin, I made a paper strip to carry the panels over both the roots of the outer wing and center wing, which forms an integral part of the fuselage, see pictures. When dry, I slit a razor knife between the two root wing ribs, so that I had on both the outer wing and the center wing a paper strip lying in the same plane. That means that a panel on the center wing will match exactly a panel on the outer wing, so that the two parts are still detacheable. I hope I am expressing myself clearly, if not just ask me.


    Next step is starting panelling the leading edge. This I made from long sections stretching for almost half the wing span, and then cutting this in three parts, so that I will have nice panel lines, while the whole remains in one continuing and straight line.


    The rest of the wing is panelled in the same way as the fuselage.


    Next comes a test build of an engine, to see how it will fit. I will put this in the forum later this afternoon.
    Greetings,
    Mixbou

    Ja, dass ist sehr schön! Ich habe das auch versucht mit meine Dgitalcamera auf Naheaufname gestelld. Es gibt eine Tulpezeichen auf meine Canon Powershot, womit man auf ca 10 oder 15 cm Entfernung fotografieren kann. Damit hab ich erst eine aufname gemacht von der Flugel wann es noch nicht am Rumpf geklebt ist. Ich habe dieser auf eine tisch gesetzt im Garten und eine Aufname gemacht als wäre man in die Cabine (lange Aufnamezeit und also kleine diaphragma fur grosse Scharftiefe), und dan in PaintShopPro selektiert und auf eine Aufname von die wirkliche Welt (Aalsmeer, in der Nahe von Schiphol, Amsterdam) "geklebt". Dann habe ich eine Photo gemacht van ein anderes Model der Super Constellation (das Modell mit Panele auf Balsaholz, siehe meine andere Threma). Mit was hin und her schieben so dass die Perspektive stimmt schlieslich die defitieve Photo zusammengesteld. Siehe die Printscreens, die hier beigefugt sind.

    It is now time to prepare the first window panel for assembly onto the fuselage.


    First however, I want to detail the inside of the panel. Airliners of the fifties had little fabric curtains in homely colours fitting the windows. Those were the days, which I remember as a 10 year old, flying in one of KLM's DC 6B's to South America, and these real curtains were much finer than the horrible plastic sliding panels airliners now have...
    For this, I used the tissue paper in which they wrap up china plates and cups in the department store. I have painted it with acrylic paint in beige, cut out small strips which are squeezed into a diabolo shape and glued to the inside of the window panel, at the window sides.


    Further, I modelled more or less a passenger head out of a small scrap of balsa, with some plastic putty, to make a rounded shape. A tiny triangular piece of paper is attached as a nose, and then I painted it with flesh colour, and brown hair, including an indication of eyes and mouth.
    Since the fuselage will be dark inside after finishing the fuselage, there is no need for too much detail, you will barely see the little head. It gives a lively effect if you see a hint of passenger faces behind the windows.


    I fixed the figure to a bulkhead inside the fuselage and finally glued the window panel onto the fuselage.


    See the pictures, which also includes an general overview with the framework of the wings and horizontal tailplane. Just to get a feeling of how the KLM livery will look like when I make the decals at the final stage, I drew the KLM stripes in a photo painting programme, so that picture is a fake of course.


    Till the next time.
    Mixbou

    I have covered the framework of the fuselage with paperstrips in such a way, that the surface is smooth and in one plane, and so that the panels can be attached with ease onto the fuselage frame, see the various puictures.


    Now it is time to start building the panels with the windows of the DC-6B. I started with a copy from the side view with a selection of the windows. I printed these windows in the correct size (1:50) to the backside of silver cardboard. (I am going to use silver cardboard on the right side and white glossy cardboard on the left side of the fuselage. That is because KLM had two colour schemes in the 1950's: white roof and aluminium at windows and vertical tailplane, but later, from around 1954 colour liveries had white painted area's at the windows and the vertical tailplane. I want to show both colour schemes on the model)


    With a punch that I bought at internet, and which has rotating punches as you push the top, giving very neat holes at various diameters, I punched out the 4 corners of each windaw outline. Then the straight line connecting the corners were cut, and an open window results. From the plastic address window of a heavy duty envelope, I then cut the outlines of the windows in the exact shape as the outline in the aluminium cardboard, and with some plastic glue the treansparant pane was secured in the outline cut out in the aluminium cardboard, from the back. In that way I made the whole length of the window panel.


    Next step is marking the correct position of the windows on the fuselage. The side view in the middle bulkhead gives a clue for this, I stuck a pin at the bottom line of the windows postion and one at the end of the fuselage and stretched a thin thread between the pins, see pictures. The DC-6B window line at the underside of the windows runs at a level of around 0,9 of the window hight beneath the side cockpit window back to the leading edge of the horizontal tailplane. Thie postion of the thread was marked on all bulkheads and longerons where posibble to give a guidance for the postion of the later window panels. I hope the pictures make this proces clear.


    Checking the fit of the panels over the length of the fuselage will be the subject of the next thread.


    So long and enjoy your weekend.
    Mixbou

    After having cut out the panel, it needs to be fitted in place. This is an accurate job, for if it doesn't fit well, it will leave ungainly gaps.


    You have to look at all sides bordering to its neighboring panels and determine where to trim, see pictures.


    Next time, I will move on to making the long side panels containing the windows.


    Best regards,
    Mixbou

    Yes Leif, the advantage in my view is, that the shape of the paper model build in panels has not 8 or 13 joints or whatever, where the angle of the shape changes, giving it an angular shape, but many direction changes, so that the curvature is better represented.


    Now some pictures on panelling itself. Using a transparant tracing paper, available at the art shop or office supply shop, I then draw the outline of a panel on the lines of two longerons and two formers or bulkheads. For small curvatures you must use longerons and formers next to each other, for long cilindrical areas, you can use larger panels, covering 2 or even 3 longerons or bulkheads. Not too many however, otherwise the "metal sheet" effect as on the real aircraft is lost.


    Small panels needing to cover complex curves, I found, can be better shaped by first moistening them with a drop of water and then pre-shaping them in the correct double curvature. I use the old cover of fountain pen, which has a sort parabolic-cilindrical shape to it.


    After that, the panel needs to be accurately trimmed to fit precisely in place. That is the subject for the next time.
    Best regards,
    Mixbou

    To continue the description of my way of building an aircraft by attaching panels on a balsa frame, the following pictures explain the process.


    After the central bulkhead is made from a sideview printed to scale (1:50) and glued to thin balsa planking of 2 mm. I glued formers which were copied from the Schreiber Swissair DC-7C and also glued to 2mm balsa planking on the side bulkhead. The similar bulkheads of the cilindrical part of the fuselage were glued at every two windows spacing (ca 4,3 cm) and at the curved shape of the fuselage I glued bulkheads at smaller intervals. The in-between bulkheads were rougly shaped, glued in place and sanded to form a contineous shape, looking alongside the fuselage.


    Then, I held thin wooden strips, 2 mm square, to mark their position on the bulkheads, putting a longeron above and below the window row, and subsequently 2 and 2 longerons evenly spaced in the remaining space above and below the windowlongerons, on both halves. Then I removed the strips. With a battery sanding machine I formed dents in the bulkheads, in which the wooden strips would fit.
    The position of the windows, taken from the side view must first be marked, and a strip goes ca 2 mm underneath and above the window position. These strips will carry the window panel.


    Next will come attaching panels in the nose section.
    Bye for now.

    Hello Paperformers,
    Triggered by Patels thread on constructing a Spitfire model using separate panels, which I also have attempted in the past, I was asked what techniques I used. I'll try to describe how I am going about with the Douglas DC-6B under construction at the moment. So here goes:


    I started by searching for accurate 3-view drawings, scanning them and printing them in the correct model size (in the case of the DC-6B around 64 cm, i.e. 1:50, so two sheets in A-4 size and putting them together.


    I happen to have a set of the Douglas Service, a magazine technical maintenance digest published by Douglas, and in the March/April 1956 issue, there was a clear drawing of the DC-6B fuselage, and of the wing planview. I also copied and printed the formers of the Schreiber DC-7C to use as the formers of the fuselage.
    See picture.


    I'll stop here and see, if this gets into a proper thread all right, including the pictures, before continuing.
    Moderators, the thread by Mr Patel was in English, and without thinking I continued in that lingo. But if you wish me to continue in German, that is OK with me, although there could be some grammar deficiencies in that case. Please let me know what your preferences are.


    Best regards,

    Hello, Dieter and all,
    I tried to open a new thread yesterday on the subject of building panelwise on a (balsa)framework, but I pushed the wrong buttons after a beautiful opening, and it was lost in the eternal bytesbin....
    I will try again, probably under the title "Panels on frame" .
    Meanwhile, the Super Connie and the Staratocruiser are not kits at all, but scratch build, from 3-view drawings. The only exception is, that the engines of the SC were copied and adapted from the Schreiber card model of the Lockheed 1649 Starliner, and those of the Statocruiser are loosely based on the engines of the Schreiber Swissair DC-7C.
    Regards,
    Mixbou (Robert)
