  1. Back to the Beginning of NASA Space Shuttle Missions Space Shuttle Launch Pad 39A with Challenger STS-6 Now it is time for presentation my Launch Pad 39A-Project in the ARC forum and I hope you'll be interested in. To the prehistory: After conclusion the NASA Shuttle program last summer with the last Atlantis-Mission (STS-135), I dedicate my first real space modeling project to the beginning the legendary space shuttle era before more than 30 years. I was inspired to this major project by similar space modeling projects in the German forum Raumfahrer.net. I decided for the STS-6-Mission with the Challenger (04.04.1983) as guidance version for my build, because I would like to build the tower version from the initial years of shuttle era with the red lattice windows and the partial red FSS grating structure inclusive hammerhead crane, which fascinated me somehow. The following picture shows the Challenger during the roll-out in the fog on their way to the Launch PAD 39A, source: NASA as well as with the lift-off to the STS-6-Mission. source: NASA To the project: To be built is the Launch Pad 39A with Launch tower, Shuttle stack, as well as Mobile launcher platform (MLP) and Crawler transporter (CT). Basic module for my project is thereby the Revell kit 4911 in scale 1:144“, in quotation marks and red, because one already is thereby for the cardinal problem of the actually mad Revell kit, the scale dilemma, to which one could be written its own chapter and said therefore some more must. For the addition of the launch tower FSS I procured myself the Detail Kits von LVM Studios. Since I decided for the STS-6-Mission with the Challenger, with the Detail kits of LVM one can represent thereby the elevator shaft of the tower in the original building technique with the red lattice windows, as it in the early years the shuttle era looked quite. In addition Detail kit No. 1 contains parts for the complete staircase in the tower, which is completely missing with Revell's 4910/4911. The LVM kits contain photo etched parts (PE) from thin brass sheet metal, with which very finely detailed structures can be produced as well known. For building MLP and Crawler I use cardboard-model kits by David Maier from EDU-Craft Deversions on scale 1:144. The kits consist in each case of 13 colored building sheets of cardboard (27.5 cm x 42.5 cm) as well as a building guidance on CD-ROM. To the scale problem: As most of you will know, Revell kit 4911 is seriously underscale and not true to scale 1:144, which lead inevitably to problems with the building. Therefore one has two possibilities, if one liked to use the Revell kit. Either one builds the kit Out Of Box (OOB), because in such a way the building groups FSS, RSS, shuttle stack and MLP fit to each other from the size, only stop is not everything on a scale 1:144, but only shuttle stack. Or one is compelling by partial scale adjustment to compromises and to scratch building, if one liked itself to orient halfway at the original. Of course one can do the build also without the Revell kit by overall scratch building. As way out of the scale dilemma I decided for a compromise settlement. Therefore I made myself first of all own assembly drawings, in order to receive a better overview. Starting point for my considerations was the following design of Gold Member Halbtoter in Raumfahrer.net forum, which shows a comparison between the Revell kit 4911 and the FSS/RSS in the true scale 1:144. source: Halbtoter The black design originates from the Revell building guidance, and the version drawn by Halbtoter by original plans of NASA is red in 1:144. It becomes clear one when exact looking that the red MLP (1: 144) does not fit no more into the Revell RSS. Since this line tangle can confuse one first however and in addition the mini MLP of the Revell kit is not with drawn in, I made myself in addition the following designs: This design illustrates clearly the descriptive scale dilemma of the Revell kit 4911, if one would build all OOB. The serious error is evenly the much to small MLP (1:200!!!) of the Revell kit, which does not fit somehow at all the total proportions. In addition it comes that also the FSS Tower (RSS probably similar) is too low approx. 7,6 cm thereby only one scale of approx. 1:168 corresponds. The image quality must accept your stop, because there two transparency sheets lie one above the other. :o The next design shows now a comparison of the RSS/FSS with MLP in 1:144 (with me black!!!) and in contrast to the Revell conditions in 1:168 and/or 1:200 (red). Considering this awkward situation I came to careful consideration in the long run that one does not come with the scale around a compromise unfortunately around, if one liked to use at least the FSS and RSS as main components of the Revell kit. And in such a way now past planning for my project looks as compromise settlement, with which I will build MLP and Crawler in 1:160 and in addition FSS and RSS in the height are supplemented around approx. 3 cm. I hope now that the result will then contently place me also to some extent. So, now however enough the preface and thus finally to the building and to the first parts and pictures. First part of my project will be the MLP platform, for which I procured myself the cardboard model kit of EDU-Craft Diversions on a scale 1:144, with which one the MLP-2 used with the mission STS-6 can build. Since I will build however MLP and Crawler transporter on a scale 1:160, first I went with the 1:144 cardboard sheets into the copy shop to reduced it to 1:160. Here is a small selection from the 13 MLP sheets. The two following pictures show now what then from it is to become, the MLP, first without source: EDU-Craft Diversions and here at the same time with shuttle stack as impressive comparison with Revell's mini MLP. source: EDU-Craft Diversions And in my next post I will show you first pictures of my building site.
  2. Thanks Pete for your impressive hymn of praise for both of us, our cooperation and the results are nothing to sneeze at. And the best part is that we all have lots of fun together and can always inspire each other. Therefore, look forward to more exciting chapters ...
  3. Hello everyone, meanwhile my friend Joe was hardworking and has already uploaded his Main Sprocket model. Source: shapeways.com (Crackerjazz) I was a bit scared when I looked at the 3D view and saw that the sprocket is hollow, which was completely new to me, Source: shapeways.com (Crackerjazz) especially since the sprockets of other crawler modelers in the Raumcon forum are full and not hollow, which I had in mind. Source: raumfahrer.net (Sascha1990) Source: raumfahrer.net (slimgo) Therefore, I was very skeptical at first and have immediately searched for suitable photos to clarify this. But in my archives I did not find anything at first, because on the normal crawler pictures you can not really see the drive wheels under the chains. In this photo, I found the first signs of cavities, if one looks closely. Source: forum.nasaspaceflight.com (AnalogMan) But in the NASASpaceflight-Forum there is a special Crawler-Transporter thread about the modification of the CT-2 for the mighty launchers of the future Space Launch System (SLS) of NASA, in which I then have indeed found clear evidences. Source: forum.nasaspaceflight.com (MechTech) Here to see beautiful in the falling sunlight. Source: forum.nasaspaceflight.com (sprtnsky) And here's a Hi-Res look into a drive wheel or through it out, which would also eliminate the last doubts. Source: forum.nasaspaceflight.com (MechTech) And so I ordered two sprockets at Shapeways, both in FUD and in FXD in order to be able to test their interaction with the Track shoes.
  4. Thanks Karl for your nice words and especially for your staying power and stay tuned. Although I have the goal clearly in mind, the way is still far ...
  5. That's right, Joe, caution is definitely wise. Therefore one condition schould be guaranteed, W2 must fit into W1, so W1 should be larger then W2, but that would fit, right? Source: microartwork.com (Mischa Klement) But I fully agree with you, it's better to first print only one sprocket, maybe in FUD and FXD, afterwards we can decide about the final Set of 18. Therefore lay the sprocket flat, because I think that this should be the best print orientation for less support wax residuals, okay?
  6. Thanks for your kind words, you're right, this is really a great collaboration between us, and Joe is a fantastic and helpful designer, as I said, a hell of a guy. But I think, that not much is missing now to make a suitable 3D printing set out of it. And that's why I've thought about the most favorable arrangement/orientation for printing and think that the sprockets could be arranged flat in a set consisting of two rows of nine wheels, whereby I would have two spare wheels. Now I'm curious to see what will come out in the end and what such a Set of 18 in FUD will cost.
  7. Hey Joe, you're a hell of a guy, these overwhelming shots are coming like a bolt out of the blue, wherefore I need to explain it briefly. After Joe was modeling the Track shows so awesome, I had asked him if he could also still model these Main sprockets, of which I need 16 pieces, which Shapeways should then print in FUD. Source: NASA Therefore I had sent him this drawing, with which he started some days ago. Source: microartwork.com (Mischa Klement) Initially, he had only used the front view of the drawing and apparently had some problems with the implementation in his CAD program (Solidworks), especially with the dimension 33,6''. But then I've pointed him to the side view, which shows that this is the measure at the lowest point of the lower curve of the wheel, what he probably did not notice. And with that he seemed to get along, as his following pictures show. As it looks the modeling seems to be pretty tricky, but he'll get it done, I'm pretty sure, so let's keep fingers crossed! I can only watch again and be amazed, the new shots look so cool, thanks Joe ...
  8. Hi guys, and because it's just now about the SOFI foam, here's a little taster from Scott Phillips' book Remove Before Flight, what happened behind the scenes ... One task after finishing the SOFI spray process included overseeing the disposition of leftover SOFI components - known as Part A and Part B - that formulated the insulation foam. Surplus liquid foam components had to be poured back into their original containers to avoid causing a chemical reaction. One day, our team member, called Buzz, came back after a "liquid lunch" to clean the machine that mixed the foam. Inadvertently, he poured 10 gallons of Part A into a 55-gallon drum of Part B, tightened the bung cap, and walked away. Within minutes, the bung popped and the 55-gallon drum exploded, immediately filling the room with foam. Everything in the room was destroyed. We never saw Buzz again after that incident ... I love these stories, which reminds me of the stories of my friend James MacLaren from the NSF Forum, like A Techno-Redneck's Encounter With NASA's Satellite ... Enjoy!
  9. Thanks Mike, and here is the Master Carver at work, Source: Scott G. Phillips and here in front of Pad 39A, proudly awaiting Atlantis' last lauch for STS-135. Source: Scott G. Phillips
  10. Thanks Pete, I'm glad that you enjoy this short introduction into the Shuttleman story. For me yesterday was already Christmas! And I like to repeat myself, it's an absolute "must read" for any space freak. Imagine, Scott has also built a shuttle stack of SOFI foam, which was used during spraying process of ET-138 for STS-135. Source: Scott G. Phillips The ET spraying process is similar to the Airbrush. Before spraying the respective model, one should first spray next to it and then pull the spray gun onto the model. And those foam remnants from testing the Spray guns Scott had cleverly put aside. Source: Scott G. Phillips
  11. Hello everyone, after my contact to the two SOFI experts Craig Capdepon and Vincent Morales was unfortunately interrupted, I got a hint from Hotdog that I could also contact Scott "Shuttleman" Phillips. He was an Engineer at the Marshall Space Flight Center in Huntsville, Alabama, and was working on all ETs during the Shuttle program. And the man with this telling nickname has written this great book together with his wife Dianne Phillips, which tells the story of his personal thirty-year Shuttle odyssey. Source: Scott G. Phillips And this book with this striking red Remove Before Flight Ribbon, that gave him the title at the same time has cast a spell over me after reading a about it and seeing this Book Trailer of his son Christian Phillips. During his time working in the program, he was also able to join his two passions - the Space shuttle and woodworking - by building one-of-a-kind handcrafted wooden tribute shuttle models in large numbers for many Shuttle crews and also for friends, here among others when handing over to the STS-1 crew with John W. Young and Bob Crippen, which also were signed by them. Source: Scott G. Phillips Realizing that each mission carried historic weight, Scott Phillips set forth to preserve each flight through his work as Master Carver, true to his motto: Long live the Shuttle's legacy. And in the meantime, I have contacted him and also ordered his book, which arrived yesterday along with a few surprises. It was next to his book with a personal dedication, as well as the red ribbon and some stickers, and as icing on the cake this piece of SOFI foam, which he had branched off in the production of the last External Tank ET-138, what I have asked him for, which I am especially proud of now. More about this, i.a. also to the explanation of this ribbon as a hanger for the book, then in my thread about the "Shuttleman" Scott Phillips, who can also be found on Facebook. So much for now.
  12. Hi Pete, yeah, With No. 4 you've hit the nail on the head. It's indeed a piece of real SOFI foam, but not direct from an ET, but from testing out the spray guns, before starting with the actually spray process. And here's the evidence. Hard to believe, but it's actually a piece of the original Spray-on foam insulation (SOFI) from the ET-138 which was flown at the last mission of Atlantis (STS-135). But how I came to this rarity, I would have to tell you separately in an own thread, if you are interested. This is a great story connected to another contemporary witness from the glorious Shuttle era who has also written an amazing book, so to speak a "must read" for any space aficionado.
  13. Hello everybody, after the slowly tiring Track shoe story today again a little puzzle for relaxation. What do you think, what this could be? At least it's not a slice of crispbread. Well, is it dawning?
  14. Hello everybody, today came the complained Set of 20-Flat Ori (FXD), Source: shapeways.com (Crackerjazz) which looks impeccable, and one can even see at all shoes the small holes in the treads. Only the sticker on the bag makes me perplex, which displays the upright set, Unlike the last Sets of 52-Flat Ori (FUD), which all had rough treads, the treads of this set are nicely smooth, as if they were not lying on the support wax, weird ... But I don't care at all.

    Bought a Printer!

    Hi Vincent, I had also asked him right away if he had, in wise foresight, extended his house by an own museum. But my friend has an open staircase and would find it brilliant if one could see the Saturn V from both floors. When he will have finished his monster project, he will certainly post pictures from both floors, I think.

    Bought a Printer!

    Hi Pete, the guy in NSF is my friend Rich O'Donnell, who had built his first crawler from the Paper kit (1:96) by LUT Guru Mischa Klement (microartwork.com). However, since he got big problems with the paper model (warping, delamination ...) due to the high humidity in his area (Olympia, Washington) he then had built another awesome 1/72 scale NASA Crawler from Styrene, for which he used Mischa's "decolored" and up-scaled kit templates, which is simply Modeling madness ... Maybe one could say this is not building Out-of-the-box (OOB), but Out-of-the- printer (OOP), but first you have to be able to create the 3D models for the printer with your 3D software, I would be glad if I could do it ... BTW, I just wanted to show another example how printers are handled elsewhere, no one has to debate this here ... The size of the Crawler model (1:48) is impressive in any case, which I once estimated: Length: 131' = 40 m = 83 cm, Width: 114' = 34,7 m = 72 cm, Height: 20' = 6,1 m = 13 cm. And if one now still put the Mobile Launcher with a height of 25' = 7,6 m = 16 cm on top of it, then the vehicle is at least 29 cm high, which is why I would say, it's stunning!!! And then just imagine still on top the approx. 2,30 m high Saturn V (111 m), that yields a total height of almost 2,6 m, really deafening ... ...

    Bought a Printer!

    Hello everybody, a friend of mine in our Raumcon forum (Sascha1990) has started a gigantic project NASA Crawler + LUT and Saturn V as 3D printing. He has bought several Anycubic I3 Mega printers and is currently printing the Apollo crawler in 1:48 scale even with interior decoration. Source: raumfahrer.net/forum (Sascha1990) Here are some great photos. So far everything looks fantastic, really very impressive.
  18. Hello everybody, today, Shapeways' big Track Shoe delivery arrived with the seven Sets of 52, which of course were immediately unpacked. And these are the total of 456 shoes for the Crawler. The new sets look well, though there are small differences in quality between the sets, as one can see on the two encircled sets, which should be due to different thorough after-treatment/cleaning. But that is no problem, because I will try anyway, to let the sets being cleaned professionally again in the Dental laboratory, as usual. And the replacement delivery with the Set of 20 (FXD), which had been interconverted, is already on the way. For the connecting bolts, I've also still found a suitable solution, for which I would use instead of the insect needles (Ø 0,3 mm) now Nickel silver rods (Ø 0,4 mm), which fit closely through the Pin lug holes. And with a length of 7 mm per bolt comes together a total length of more than 3 m , which would correspond to 11 rods à 30 cm, which I will still reorder soon.
  19. Stay tuned, my friend, and you will see it ...
  20. Hello friends, although I have already experienced some things, Shapeways still has some surprises in store. Today came the already announced Set of 20 Flat Ori (FXD). But after I unpacked it, I could not believe my eyes. Because that was not the Track Shoe-Set I ordered, Source: shapeways.com (Crackerjazz) but any other one with little mini parts, what of course I've immediately complained. Mitchell Jetten (SW) but immediately apologized in return: Oh no, I'm sorry to hear we shipped the wrong model to you. I have raised a complaint (CT-48214) ticket right away and asked our production team to reprint the correct model as soon as possible. There are also less beautiful wonders by SW ...
  21. Hello everybody, the Set of 20 is already on the way, and of the remaining seven Sets of 52 six are already printed, only the last one is missing, which is why the shipment will hopefully follow soon. And thus the Crawler would be almost finished already ... P.S.: Your Shapeways shipment is on its way!
  22. Thanks Pete, well, that was a great coup, with which I surprised SW. Hopefully the odyssey with the Intertank will also end well, so keep your fingers crossed.
  23. Hi Joe, and thanks once more for your fantastic 3D modeling job. As you see, nothing is impossible, sometimes one has to take full risks and to play vabanque, according to the motto: Nothing ventured, nothing gained. This was an inner inspiration, what should already happen? In the worst case it could be rejected, so what? And luckily it worked, in the meantime the remaining seven Sets of 52-Flat Ori are In Production.
  24. Hello everybody, today, the 52 Set-Flat Ori (FUD) came as if there had never been any problems with printability. Unbelievable, but SW is really unpredictable ... And I must say, the set not only looks good, but even better than the previous two sets with the upright standing shoes. Here is the top side of the set, right next to it, the three connected shoes from the previous 20 FUD set. And here the bottom side with a view of the treads, which feel a bit rougher, but which is explainable, since they were touched by the support wax, but which is not a problem. But the top and side surfaces are smoother because they were not in contact with the wax. And if one looks carefully, one can even see the small holes (Ø 0,2 mm), although not on all shoes, but one could even drill out them, if it should be, although they later are hardly visible anyway. Here's a little closer view. And so I will seize the moment and order a further seven sets, wherewith I would then come on the required 456 Track shoes, but I will still order additionally a further Set of 20 to be on the safe side.
  25. I can also only pull off my hat to these 3D artists here. If I could program 3D models, I would also buy me a printer and print some parts. But it also works differently, only for special things, I would not want going without it, especially since Joe is such a gifted 3D modeler.
