  1. Thanks Mike for your nice compliments, but please not too much understatement of yourself. Nothing is impossible, therefore Learning by doing is the way to go, and with the New Ware detail kit you made a good choice, because this kit is an amazing help for pimping the Revell Shuttele stack, which is why I try to use it myself for my Airfix stack. BTW, I don't know if you know it, but check out the thread of our friend Mike (egt95), who did use this Newware Kit for his Space Shuttle Discovery STS-41D successfully.
  2. Hello everybody, who wants to know more about the ET cabling as well as about the Cable trays and their Thermal protection system (TPS), here one still can find some interesting information. Source: System Definition Handbook SLWT (Lockheed Martin) Source: System Definition Handbook SLWT (Lockheed Martin) As one can see in the first picture, it was distinguished between Internal and External LO2/LH2 Cabling. But there is another important interface, namely the ET/SRB interface between the ET and the SRBs, about whose cables, sensors, etc. the separation of the burned SRBs has been activated. And unfortunately, this interface with the associated Cable Tray is also missing in the Airfix Kit and therefore also needs to be scratched. In this photo of the ET-8 one can see the transition of the Cable Tray from the vertical strut to the SRB Support, where the wiring passes through the Upper Attach Strut. Source: forum.nasaspaceflight.com (woods170) This also makes it clear what these strange extensions at the end of the vertical strut mean, which I have noticed time and again. Source: nasaspaceflight.com (woods170) These are the cable ends running from the root point of the Upper Attach Strut to the Aft ET/SRB Attach Ring (see previous picture). And these are those cables that can be seen in this photo, which can be seen at the bottom of the SRB Cable Tray in the previous image, Source: NASA and then run into the booster via the Upper Attach Strut.

  4. Thanks Pete for your appreciatory words. And if your jaw is dropping, then I can imagine your astonished face, and have to smirk secretly. But these detailed analyzes belong for me to my understanding of this impressive technique, even if they seem to be too much for some. And Scott Phillips has helped already me with many great images, he was after all close for 30 years.
  5. Have you meanwhile created a Decal sheet for the Early Missions that I can use for my Challenger?
  6. Hello everybody, but this is just one side of the ET/Orbiter Interface. But the other side on the Shuttle has to fit too. And therewith it looks pretty poor on the Airfix Kit, because the two Orbiter doors are not present, let alone their deepenings in the opened state, just like one needs it for the Stack (ET/Orbiter). Source: NASA The least would therefore be a solution in which one could glue a Decal or a paper printout of the two doors in the opened state onto the appropriate place, which would look a bit better, namely something like here. BTW, if I remember rightly, Hotdog had provided similar decals in his set, right, Brian? It would be even still better, of course, if the two deepenings were really brought in, however, and then glue the Umbilical decals into, or simply the printout, and the two doors in between, what I could imagine. This is what my friend Mike (egt95) did in this forum here on his STS-1 stack. Source: arcforums.com (egt95) But since this place at the finished stack on the MLP can not be seen anyway, glued decals/printouts without the openings, but with glued doors would actually suffice. In the meantime I started with the modification of the Airfix-Longerons, which protrude anyway and do not rest on flat. These are these stripes on both sides at the end of the LH2 Tank, on which the oblique Thrust Struts and the Vertical Struts are mounted, because these parts do not look like in reality, as one could see already on this well-known photo of the ET-8. Source: forum.nasaspaceflight.com (Jester) For me, it seems, that the SOFI patterns has been leveled in this area, with only the front wedge-shaped part is supporting the oblique strut. And this I have modified by sanding off the Kit-Longerons accordingly, whereby now the front slant ramp must be filled accordingly. And here I have tried to adapt the TPS cladding from the Newware Kit, for which I had to sand off approx. half of the lower block of the Airfix-Strut, however, whereby the lower part of the Resin-cladding seems too clunky to me, which is why it still has to slim down a bit. But every beginning is difficult, just do not panic ...
  7. Hello everybody, okay, I admit that this photo by DaveS takes some getting used to, and I also took some time to find my way, although I've already seen many similar photos, but not yet with opened cable tray. Source: forum.nasaspaceflight.com (DaveS) What strikes all these photos is this ominous 'distribution box', who initially looked orange-brown, as here at the mission STS-6, Source: forum.nasaspaceflight.com (woods170) or here at STS-47. Source: georgesrockets.com (George Gassaway) Only with the later missions he looked then gray, as in the following picture. As one can see, from this 'distribution box' the yellow marked LH2 Cable Tray seems to branch off, which then on the front of the Crossbeam runs to the other side to the LH2 Umbilical. Source: forum.nasaspaceflight.com (DDG40) The confirmation for my guess came then with this great photo by Scott Phillips, whom I've also consulted, here with the front TPS covering removed. Source: Scott Phillips And with that the hitherto searched interface of the LH2 Cable Tray gradually becomes clearer, which I have circled here yellow, which discharges into the TPS cladding of the Vertical Strut. Source: forum.nasaspaceflight.com (DaveS) And, as I've learned by now, not only the LH2 cables run inside the LH2 cable tray, but also the LO2 cables, which was not clear to me yet. But as I learned from DaveS too, the cable trays that time were named after the ET tanks (LH2/LO2) and say nothing about the cables running in it, but what one has to know. And by this picture-in-picture montage will hopefully become clear, where this place is located, whereby this image is rotated 90° and the TPS cladding on the front of the Vertical Strut is open (blue arrows). In the next photo one can see the opened LH2 Cable Tray in front of the crossbeam with the cables running into it, which lead to the LH2 Umbilical, Source: Scott Phillips as well as here the cable harnesses laid in the opened knee of the LO2 Cable Tray. Source: Scott Phillips And so I now know about how the cable trays and other lines run, and thus can try to scratch this ET/Orbiter Attachments accordingly.
  8. Hello folks, to this question I also consulted my friend DaveS (forum.nasaspaceflight.com), who also had some interesting photos in stock, like this one. Source: NASA on which unfortunately one can not see this interface of the LH2 Cable Tray that interests me, as it is obscured by the Vertical Strut as in most photos. But at least one can see more of the arrangement of this gray 'distribution box', which apparently has such a function. Afterwards, I've continued to search for the interface myself, and as one could already see in this photo, Source: NASA the LH2 Cable Tray seems to run diagonally upwards at the point A, possibly to this 'distribution box', as it also appears in this photo of the ET-8 (STS-6). Source: forum.nasaspaceflight.com (woods170) The matter got a bit clearer to me when I saw this photo of the ET-119 (STS-121) zoomed in, Source: NASA on which one can see at the point A the continuation of the gray LH2 Cable Tray, but which not directly leads to the 'distribution box' but apparently to the Vertical strut. And then suddenly the penny dropped, when I've again checked this photo again and asked DaveS for it. And on this image detail of ET-122 (STS-134) one can see this interface almost even better. Source: forum.nasaspaceflight.com (Jester) And finally, DaveS confirmed my guess and sent me this detail photo of the ET-125 (STS-122), whereat the orientation is a bit difficult to see at first glance. Who wants, can first try to find one's way before it goes on with the further course of the LH2 Cables, as they still did not arrive their goal at the LH2 Umbilical ...
  9. Hello everybody, in the meantime, I went into more detail to find out where the interface between the LH2 Cable Tray and the Aft ET/Orbiter Attachments is, or how the cables out of the the LO2 Cable Tray get there, especially since this is a pretty tricky affair and there are hardly any direct photos of this interface. One also should know how the cables run out of the cable tray onto the LH2 Tank from point A via B and C respectively D to the LO2/LH2 Umbilicals and wherefore this gray box (?) is used, which could possibly be a kind of distribution box? Source: NASA Maybe there are useful hints from the forum, if so, then always ago with it.
  10. Thanks my friend for looking in on me and stay tuned.
  11. Hello everybody, to get in advance an idea of the size of the two Umbilicals, which I want to scratch, I reduced the drawing to 1:144 and cut out the Crossbeam with the Umbilicals and Cable Trays and put it onto the Crossbeam of the Airfix ET. And now one can see how small these miniature parts are that always look so huge in the photos. Here is a photo in daylight. And matching it I have a great photo of my friend Scott "Shuttleman" Phillips (see arrow), standing as young but then already about 1.80 m large greenhorn next to a Original LH2Umbilical, which shows the true size of this part. Source: Scott Phillips Mighty impressive, right? By the way, Scott Phillips has been busy for quite some time with two very interesting projects in honor of the 50th Anniversary of the first Moon landing, which is imminent. Source: NASA Since I've supported him a bit, I was also let in on, but I had to promise him not to reveal anything, as it should become a surprise. Here one can see Scott and his wife Dianne in the workshop of the creators before the internal unveiling of the "Corpus Delicti". Source: Scott Phillips Only so much in advance, it has something to do with historic wood ...
  12. The master is completely in his element! Great job Joe as always!
  13. Hello everybody, and since both Airfix and Revell did not consider these two Umbilicals in their kits, but at least should be hinted, therefore here another view showing the connection of all lines and cables between the ET and the Orbiter Doors. Source: NASA And who wants to follow all the details exactly, can look at this drawing and even find some dimensions, whereby it should be noted that the struts are shown here without TPS. Source: System Definition Handbook SLWT - Vol. II For the further building process, it will become useful to model the ET/Orbiter Interface Attachment incl. Umbilicals separately and to glue it only after the Flour coating, priming and painting of the ET. Then I need to mask only the connecting areas of the two Longerons as well as the foot points of the vertical struts. Then follows the mounting of the LO2 Feedline as well as the Ice Frost Ramps with the two GH2/GO2 Press. Lines and the Cable Tray on the LH2 tank, as well as the installation of the GO2 Press. Line along with its Ramps and Cable Tray on the LO2 tank. And only at the very end the complete and painted ET/Orbiter Interface Attachment are glued and the corresponding line connections adjusted at the interfaces. So far to the theory, that wants to be well considered. I just hope that this can also be realized in practice.
  14. Thanks Mike for this helpful comment, I fully agree with you and did plan to myself to do this way. At this point a special thanks to you, Mike, because I have seen with astonishment, that you did re-store your awesome Revell STS-133 Thread by re-inserting all lost images. That's a great thing, there you have also very nicely scratched some special details of this ET/Orbiter Interface like the Umbilical Assemblies, where I can get a lot of helpful suggestions. P.S.: Small correction, as Mike told me, Photobucket has restored the pictures, unfortunately with their annoying signatures.
  15. Thanks guys for understanding my situation with this SOFI texture. Hello everybody, for masking before Flour coating, I need a stable and secure solution, either with masking paint or tape, especially since I have the cover problem as with the Ramps even with the other ET add-on parts, such as with the ET/Orbiter Interface Attachment, this is the rear support structure of the orbiter with the different vertical and diagonal struts, as well as the LH2/LO2 PAL Ramps, etc. The Airfix solution of this Interface attachment, on the other hand, looks a bit more modest and therefore is not quite realistic, so there some scratch building is needed.
  16. I fully agree with Mike, dipping the tank in lacquer would be really adventurous and would probably mean the end of all dreams. In order to produce a more 'fluid pattern', as you call it, the priming of the flour coated strip spiral and the subsequent airbrushing in several layers should suffice.
  17. Thanks Mike, I think it's important that the stuff should trickle down nicely to scatter itself evenly, like the rice flour doing, unlike wheat flour. And that's why I'm more than satisfied with the last result.
  18. Hello everybody, here for comparison a small photomontage of the new SOFI Pattern structure in the original image of the ET-8 during the Roll-out, which shows that it looks not so bad, right? Source: forum.nasaspaceflight.com (Jester)
  19. Thanks Pete for your nice comment, yeah, how do you say? Necessity is the mother of invention! I was surprised myself - how good that I asked the Lady in the supermarket. A little bit of fun is always good, because without fun there is no progress ...
  20. With or without the Belly Tiles?
  21. Hello everybody, now I can also present the pictures after brushing off the surplus flour, which have pleasantly surprised me, because now the proportions of the SOFI-Patterns fit much better to the diameter of the Intertank, which results in a completely different and more realistic look of the texture, especially since the floured surface looks much finer and smoother this time, which is certainly due to the finer Rice flour. And if I now imagine this structure with primer and painting, then this should presumably give a quite acceptable overall picture. And then I carefully subtracted the Maskol bonnets from the Ramps, whereby I had to realize that the ramp, glued onto the tape strips (left) had no proper hold and has gradually peeled off during unmasking. Consequently, the splices for the Ramps should be exposed before the Flour coating and covered separately either with a piece of masking tape or with Maskol and then the Ramps to glue only after Flour coating. And with these positive impressions, I can now continue with a clear conscience.
  22. Hello friends, after the Flour coating with the Rice flour, I can now show the images too. Here the Intertank Dummy already hangs in my tried and tested Flour chamber, and is waiting for the UHU glue spray mist, which has covered it here after some turns from all sides. And then followed the generous Flour coating with the rice flour by using a sieve, whereby the flour was pressed smoothly between several times with the finger, which this time everything went much looser from the hand. Finally, the loose flour was removed by tapping at the rotating rod, so that everything can dry thoroughly first, and then tomorrow the excess flour will be brushed off.
  23. Hi Pete, here at Andromeda you can get the whole stack 1/144 by Realspace Models together with the Energia. Source: shop.strato.de Here's a bit larger image. Source: realspacemodels.com No matter which kit you choose, this model will be exciting, I'll stay tuned.
  24. Hello everybody, and now to the announced Ice Ramps from the Newware-Enhancement Kit (NW131), which I wanted to glue on before Flour coating and therefore had to mask, in order to protect them, for what I used Maskol. These are two of the Ramps (R23), 14 of which sit on the LH2 Tank. I've glued the left ramp directly onto the tapes with Pattex-CA, the right one directly onto the uncovered place, to see how far the ramps and their openings for the two GH2/GO2 Press. Lines will be covered by the flour coating. Here are the two Press. Lines (2'' in reality), for which I'll use Nickel silver (Ø 0,35 mm). Afterwards, the ramps were masked with Maskol, whereby I hope that the masks can still be removed well after the Flour coating. And so nothing stands in the way of Flour coating with Rice flour, on the result of which I am already curious.
  25. Hello everybody, so everything would actually be prepared so far that I could start with the gluing of the continuous spiral (Barber pole) from the 0,75 mm wide tape strip, with which I wanted to simulate the SOFI Pattern, which is followed by the Flour coating as well as priming and airbrushing. But since I'm still not completely satisfied with the quality of the Flour Coating, I wanted to try a few things before yet. Therefore, I will do another Flour coating attempt, for what I have first looked at the local flour varieties in the supermarket. And as I stood in front of the shelf with the many flour bags and was spoiled for choice, stood next to me an elderly woman, who somehow looked competent in terms of baking. And then I asked her briefly if she knew which flour would be especially fine-grained. And her tip was Rice flour or Cornflour, whereupon I then searched for. Bur since faced with so many bags I haven't seen any Rice flour but only found the cornflour, a coworker could show me the rice flour. At home I then made the comparison to my so far used wheat flour by Heimatsmühle (Type 405), the sample of which can be seen on the right in the next picture, whose loose bulk is similar to the cornflour, with both varieties lumping a bit. In contrast, the Rice flour actually seems to be more fine-grained and trickles rather than lumping, which gives me hope for a better result in the Flour coating. Then there was the unanswered question as to whether I should glue the Ice Ramps for the two Press. Lines before or after the Flour coating, whereby I meanwhile tend to the first variant. But then it is necessary to mask the glued Ramps before Flour coating, which is why I tried the Maskol by Humbrol, whereby I was amazed and frustrated that the stuff in the jar was almost completely lumped, because it was probably already too old. Here one can see a few drops of the residual liquid on a Styrene plate and on a glued small piece of Evergreen profile. After drying, one can easily peel off the rubbery skin. Then it was time for the preparation of the new Flour coating test, for which I've used the now no longer needed Airfix Intertank, on which I've glued the 0,75 mm wide tape strip as a continuous spiral (Barber pole). This time, I have dispensed with the 0,5 mm wide spacer strip and glued the strip by eye and pressed on each winding immediately a bit stronger, whereby I have even reduced the distance even slightly. This brought the strips even closer to the estimated Valley-to-Valley distance of approx. 1,3 mm. For this complete gluing of the IT I needed about 1 h , which was certainly pure stress for my still sharp eagle eyes, whereby I'm amazed at how evenly I have managed this. Here are two more shots in daylight. Next to come are the 'masked' Ice Ramps.
