  1. Hello everybody, while the holding device assumes more and more shape in my mind's eye, I also have to understand the course of the Fuel Cell Pipes, especially their starting points on the Side 2 in the Bay 7 (GH2) and Bay 8 (GO2), as well as their further course to the MLP corner and then on the Side 1. For this purpose here are a few pictures for illustrating the wiring course, for the sake of simplicity, just behind the corner on the Side 1, whereby the two upper lines are the GO2 Pipes, and the two lower ones the GH2 Pipes. Source: NASA While the two GO2 Pipes are running below the Blast Shields to the LOX Tunnel, the two GH2 Pipes run downward in front of the Blast Shield and then below the AccessPlatform up to the LOX Pneumatic Interface Plate in the Bay 6. And so it should fully suffice if I let end up the pipes at the circled places, especially since one can not see their further course on the model. But regarding the starting points of the Pipes on Side 2 in Bay 7 and Bay 8, it's still not quite clear in detail, because one can not recognize it exactly enough, which is why I initially thought that the pipes would come out of the MLP wall. Source: apollosaturn.com (John Duncan) And even this image, which reveals more details already, cannot give a more exact explanation. Source: Library of Congress It is only clear that the two GH2 Pipes in the Bay 7 running down close to each other, while the two GO2 pipes in the Bay 8 run with a significantly larger distance. But then suddenly I remembered, that there is a NASA panorama with a great view of the Side 2 of the MLP-2 from Level 75 on the FSS, on which these two bays might be visible more detailed. And lo and behold, quite right, and therefore here the ultimate shot with the linked panorama, Source: NASA wherewith (now) almost all the uncertainties for scratching should be eliminated. As can be seen, the pipes start on an angle profile and then take a multiple angled course upwards, and follow after merging in the Bay 7 as a quadruple bundle to the right up to the beginning of the side. As coming from NASA's plans, the circled jacks are Moisture Sensors, and one can even see how the pipes are bolted to the angle profile. Source: NASA And with that the matter looks already much more friendly.
  2. Hello everybody, this is certainly a rather demanding and complicated undertaking, which would in any case require a suitable holding jig to be able to paint this wire bundle by airbrush in a first step. Meanwhile I have fiddled around with a solution and have also an idea already. One would have to reproduce the girder structure of the Side 2 from Bay 8 to Bay 1, which can be seen in this image, Source: Library of Congress as a kind of template made of Balsa with the tiny supports strips on girder dummies, and glue the wires on it, whereby the front ends as well as the rear ends should have to be angled already and fixed somehow. The other pipe supports, sitting on feet on the side wall, would have to be painted and glued separately, and then one could glue the painted thin bundle with the support strips onto the girders and the other wall supports, and also lay around the corner. This sounds surely a bit adventurous and perhaps it's hard to understand too, but maybe it's possible. The difficulty results from the minimal distances of the four thin wires from only 0.2 mm on the 1.5 mm short support strips. This filigree arrangement of the wires I have tried to apply now. First I used spring steel wire 0.1 mm, which is unsuitable because the wires are magnetically attracted by the tweezers. But with nickel silver wire 0.1 mm it was possible and looks like this. This is my momentary idea, but maybe it's also too crazy and cannot be realized, therefore I'm still a little bit sceptical, although my feeling tells me that it could work ...
  3. Thanks Pete for your truly refreshing comment, which made me also laugh out loud. But it's all no problem, as long as I do not have to rip out my last hair for scratching such thin pipes ... BTW, you surely know the proverb: Beggars can't be choosers.
  4. Hello everybody, well, so is it with the details, which I wanted to start scratching, but which on closer inspection suddenly vanish into thin air ... Therefore it is absolutely necessary to take care to the mission they are based on and whether they are relevant to the own mission. But that I did not keep in mind at John Duncan's MLP-2 images of 1998, because I was so thrilled about their details, a typical case of Not a bit of it! Afterwards one is unfortunately always smarter, but aside from the STS-1, there are relatively few usable Hi-Res images from the first missions, especially from Side 2, where it unfortunately looks gloomy. That's why I took the trouble and have specifically investigated the first MLP-2 missions until the end of the 80s once again, finally to get information about these ominous Firex Lines. And these were the following missions: Challenger: 1983: MLP-6, MLP-8, 1984: STS-41B, 1985: STS-51B, STS-51F, 1986: STS-51L; Discovery: 1984: STS-41D, STS-51A, 1988: SSTS-26; Atlantis: 1985: STS-51J, STS-61B. And in doing so, I found out, that 1983 during the first missions, there was no transition of the Firex line from the Side 2 to the Side 1, but first in 1984 at the Challenger mission STS-41B, as one can clearly see in this image, especially with zoom. Source: NASA At the previous mission STS-8, this transition did not yet exist, as one can see on this image unfortunately not so sharp, but nevertheless. Source: NASASpaceFlight.com Forum What one can see as a shadow is the detail (?) on MLP-2, what I've already mentioned in the last post, which I will now still examine carefully. And therefore back to the Side 2 of the MLP-2 (1998), on which one can see it also only schematically in the zoom. Source: apollosaturn.com (John Duncan) These are actually four thin Fuel cell pipes (Ø 0.5'' = 12.7 mm) for the fuel cells of the orbiter, namely the two upper GO2 pipes and the two lower GH2 pipes. More clearly, this bundle is seen on this image from the MLP-2 at the STS-132. Source: NASA If one really wanted to scratch these four pipes, one would need wires with a diameter of about 0.1 mm, which I procured some time ago. BTW, here is such a wire (Ø 0.1 mm) in cosy togetherness with a hair (Ø 0.05 mm) of mine, whose color however will not be betrayed.
  5. Hello friends, and thus to the next pipe on this side, whereby I assume that it is a Firex line. The same line there is also on the Side 4, to which we will come later. This pipe is a bit thinner than the first two pipes, it starts somewhere in Bay 13 and then it takes the marked course to the front corner of Side 2, Source: NASA Since on this image one can recognize the beginning of the line unfortunately just as little as on this image of the MLP-2, Source: apollosaturn.com (John Duncan) I have consulted again the Street View panorama of the MLP-1. And here I have found a suitable perspective, on which one can recognize, that the line comes out of the wall of the lower MLP-B Level to the right of the door and then runs first to the top and then to the right. Source: NASA (Street View) Compared to the first two pipes (Ø 0.6 mm), this line should have a diameter of 0.4 mm, for which I also used Cu wire. And here the test line is temporarily layed down, but at the lower end it must be shortened and angled. At the other end of the line at the front corner to the Side 1, I was initially not quite clear about their real run during the STS-6, provided that it already existed at that time. As can be seen in these images from John Duncan's collection (1998), the line runs around the corner to the Side 1, Source: apollosaturn.com (John Duncan) and flows then in the thicker Firex main line, which is running under the Blast Shields to the other end of the side and then on Side 4, where it ends in Bay 13. Source: apollosaturn.com (John Duncan) And now comes the surprise, linked with a fat On my standard reference image of the STS-6 one can see that there was no continuation of this Firex line behind the corner on the Side 1, maybe it was extended only later up to the main line, but it is only questionable when, respectively whether at all? Obviously, there is something else, whereat the red arrow points, to what I'll come back later. Source: retrospaceimages.com (STS-6) To the right side of the Side 1 it looks similar, where the red Firex main line ends in front of the corner and only some cables run around the corner. Source: retrospaceimages.com (STS-6) And so I have arrived at a point where I have to rethink everything, because that would mean that I can save myself the thinner pipe apparently, because it still did not exist at that time presumably. But about it I just have to sleep tonight ...
  6. Hello everybody, today only a short flash from a first attempt to bend the two thin pipes. For this I have used copper wire Ø 0.6 mm and a copy of the Side 2 of the MLP-3 as bending template, which is why I had to correct the double kink a little bit. And these are the two pipes in the raw state, from which the left ends are now adapted to the attachments on the console and the right ends must be shortened and angled. Sorry, but the light conditions are unfortunately not the best. That was it already for the moment.
  7. Hello everybody, then I tried to paint the caps of the connecting sockets red, first times with two test rods. Since the lengths of the caps with the brush by hand are not to manage with uniform lenght, I have masked the rod tops accordingly. And now it looks better, to the left is a second variant of the handrail, which has only a thin disc at the front, which corresponds more to the real part, which is more likely a blind flange, as I have now found out. Since I would like to paint the small through-sleeves by Airbrush, I have pinned the parts on my Balsa-Holding strip, which I had used for the lampshade lacquer. And in this airbrush job, also a few profiles for the pipes on the side walls will be sprayed, which I have already prepared. These are, inter alia, the two lines with the double kink, Source: apollosaturn.com (John Duncan) whose connection on this console with the two attachments was a mystery to me until now. In the meantime, NASA has also digitized the photos contained in the so called MLP-Report and made them available online, from which I have already taken a lot of detailed information. And these reference photos (unfortunately only black and white) are predestined for detail studies because of their high resolution. Source: Library of Congress In addition to this image as JPEG (316 KB), on which one can not see enough details, there is also a huge TIFF format (38 MB), on which one can clearly see that the two pipes are actually connected to these two attachments, which I had so far only suspected. And on this image one can also see that the front part on the GN2 Line is probably a blind flange. Source: Library of Congress This version of the connectors with the covers is only available on the MLP-3, on the MLP-2 they are missing , as one could already see on this earlier image. Source: NASA (Street View) In any case, similar connector caps are located in front of the attachments, as can be seen from this perspective. Source: NASA (Street View) That this connection console was still slightly different on the MLP-1, can be seen in this image. Source: NASA (Street View) The MLP-Report contains, among other things, also a drawing of the Side 2 from which this image section comes, from which I have determined the dimensions of the box (Fire Hose Reel). Source: Library of Congress And these are the prepared parts for the box of 0.3 mm Styrene with two support struts (0.5 mm x 1 mm), whereby I assume that these were more likely angle profiles, for which I could use an already painted brass profile (1 mm x 1 mm). So much for the theory, which I now only need to put into action.
  8. Thanks for your flattering words, which praise me to the skies ... I'm glad if you like what I'm doing here, I only try to give my best.
  9. Thanks Manfred for your nice compliments, yep, the scientific curiosity and the researcher's urge are still inside me and always stimulate me anew, to get to the bottom of it. And besides, I do not want to paste the details only after feeling anywhere.
  10. Hello friends, now also the last fields on the Side 4 are newly re-glued, which looks now like new-born, compared to the side from the paper kit and only awaits their details. And because we are dealing with cosmetic, I have attached the yellow markings on the LH2 Vent Line, seven in number, as can be seen on this image from the STS-8. Source: NASA In order that the somewhat bulky little decals can easier cling around the pipe, I had to use Decal Soft again. And that's how it looks on the MLP. After the "renovation" of the side walls they look indeed a little bit bald, but now I could finally start with the detailing, first on the Side 2. I am still in the dark, which especially concerns the detail structure of this side during the STS-6, which does not make scratch-building easy. I started with the through-sleeves and connecting sockets of the three ports for the ECS purge lines, Source: NASA (Street View) for which I have separated 1 mm wide rings from the wire end ferrules, which protrude forward on the wall. The small connector to the left beside the downspout belongs to a GN2 pipe, the front of which looks like a handwheel and also sits in a through-sleeve, what I then have tried to scratch laboriously. The sleeve is a piece of a wire end ferrule (Ø 1 mm) and the wheel is from a section of a rod (Ø 1 mm), which I tried to slit all around with the cutter. On the right lay the round bars for the connecting sockets. And so this part in the sleeve looks so far, an attempt was worth it at any rate.
  11. Hello guys, today finally came the birthday gift for my grandson Max, which I bought on May 31st, who will surely be in for a surprise. But do not worry, the box remains closed, because I will not be distracted from my MLP.
  12. Hello friends, since most probably have yet to wait for the kit, here already the grandiose building instruction (33 MB), which is now also available online. Well then have a lot of fun with the dry run.
  13. Hello everybody, yep, with the Saturn 5 LEGO has obviously hit the bull's eye. I have already ordered it yesterday, should come in the next days. And this is Felix Stiessen, one of the two fan designers of the LEGO NASA Apollo Saturn V, at the signing event at the LEGO Store in Shopping City Süd located in Vienna, Austria. Source: ideas.lego.com Thanks and congratulation Felix!!!
  14. Hello everybody, since in the laying of the two thin pipes on the Side 2 inevitably the "roof"gutters come into play, Source: apollosaturn.com (John Duncan) I have made a couple of new attempts in the meantime to get some bending feeling again, because unfortunately there is nothing off the shelf. For my first attempts at the very beginning of the project, I got an aluminum tube Ø 2 mm and filed down carefully the upper half with a fine mill file, which basically works, but which was quite elaborate and laborious. Therefore, from today's point of view, I would rather want to return to the already tested variant of moulding a sheet metal strip over a round bar. For the back Gutter 3 over the Bay 18 I need a 23 mm long piece, after it follows an elongated substructure, on which two sockets with connection stubs sit, whose purpose of use I have not yet been able to find out however. But no matter, maybe I still can discover it. And as it looks like, the two thin pipes seem to be attached to these sockets when I see this right. This is indeed a picture of the MLP-1, Source: NASA (Street View) but on the MLP-2 this part looked similar, as one can see on this image detail, only the two sockets sit more in the middle. Source: apollosaturn.com (John Duncan) On this panorama one can see the details more clearly. Source: NASA (Street View) This time I've used thin aluminum sheet (0,2 mm) for the gutters, cut out a strip of 23 mm x 3 mm and molded it over a round rod Ø 1,5 mm, but the strip can also kink axially, instead of curving itself evenly, which should be better prevented. Here one can see the filed down pipe (above) and below it the molded gutter piece, which one can do more precisely than by filing. In order to prevent this axial kinking, I will lay the strip on a rubber pad on the next attempt and then press down the round bar from above, perhaps it will work better then. However, how good this can be done with the longer strips, we will see then. Afterwards, I started with the face lifting of the Side 4, on which there are also some pipes and cables, which I would like to scratch. And since they lie above the vertical struts, then the 2D textures and shadows on the wall template disturb the picture, which would certainly look comical, especially since the 3rd dimension is missing anyway. So I have started to cover the Bays on this side with matching parts, which was quite tedious because one had to measure all the fields and covers before, so that they fit into the fields. Then came the Bay 16 with the four Vent Mufflers, where I first removed the two lower mufflers. But since the shadows there just look too brutal, I then also removed the two upper Mufflers to be able to cover this bay completely new. And the front and rear MLP-2 identities have meanwhile also been renewed and were placed in the right bays. Afterwards, the two vent mufflers were glued again, which now looks much better and corresponds to the original. In order to have more freedom of movement, I've put my turntable on a stand to have easy access from all sides, which makes the work much easier. Now only a few fields have to be renovated, which will be done tomorrow. As far as for today, and thank you for watching.
  15. Hello LEGO Saturn V Fans, in NASASpaceFlight Forum I came across a contribution by Simon Bradshaw (major_clanger), a lucky fan who got the kit in advance last Saturday via John Lewis (UK department store chain) who had it available for online order. Source: major-clanger.dreamwidth.org Over the weekend he spent about 6 hours for building it. Here he has presented his build with a lot of awesome photos. He is enthusiastic and said inter alia about this kit: "It's an amazing kit. Within the limits of what you can achieve with Lego, it's remarkably accurate. It's also very impressive - not only is it huge (about 1:110 scale) but it's very solid." See you thursday ...
