    Shapeways best resolution?

    Do you know, if there is a price difference for White Processed Versatile Plastic and White Natural Versatile Plastic?
  2. 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.
  3. Hi Joe, please wait with uploading, because I wanted to make sure that I understood SW right, and therefore have asked the guy once more. And let me know the price of this 40 set in FUD and FXD before. Maybe the 20 set ist better for handling during unltradonic cleaning, or I have to to devide it. I think that this is the most favorable orientation, which I do not see here in ARC, but only in the email, funny !!!

    Shapeways best resolution?

    Hi Brian, I thought that White Natural Versatile Plastic is the new material name for the old WSF. Is White Processed Versatile still a better variant, or is it the same?
  5. Hi Joe, thanks for your modifications, which is the same configuration as by Simpson 3D Design. . Source: shapeways.com (crackerjazz) But if I understood Shapeways correctly, they consider the marked arrangement as the most favorable for the printing direction with the fewest wax residues, if one would turn this arrangement and lay the shoes on the running surfaces, which would be very important for the required Ultrasonic cleaning. If necessary, I'll ask them once again. BTW, as far as I know, Shapeways offers the possibility for showing the placement of the Support wax in the model. Do you know that, or can you check that for the variants? Maybe Bill can say something from his view too, if he's still reading?
  6. Good morning everybody, Shapeways has notified what I already suspected and what is actually logical. Printing a set with sprues will be a bit cheaper to print due to the production team only having to handle one single model instead of 20 separate pieces. So planning the models and cleaning/post processing them is cheaper. While it's more material cost, the labor/handling costs are lower for them! And furthermore I did ask, what arrangement of the shoes in the set is more favorable for printing, upright like in Simpson's set (above), or when the shoes would lie flat? And the answer was: The position doesn't really matter, though it's favorable to keep the parts flat and as close as possible (smaller footprint). If you keep them flat (rather than stacking on top) it will reduce the amount of wax required to print in Fine Detail Plastic (so less support material sticking to your model), which seems to me very important ... Therefore, dear Joe, you should please design a set, okay? BTW, unfortunately they don't have any quantity discounts, since the material costs and labor costs remain the same when ordering it once it 100 times.
  7. Hey Joe, Can you also design such a 20 Piece Set like this one by Simpson 3D Design, because I suspect that printing a set would be cheaper than printing 20 individual shoes, right? Source: shapeways.com (Simpson 3D Design) On the other hand, this set is more material, and therefore it might be even more expensive ... Therefore I've contacted Shapeways, to find out, what is more favorable? Maybe there is a quantity discount for 456 shoes too? BTW, their material is now called Smooth Fine Detail Plastic, which is the old FUD.
  8. Hello folks, this is the news of the month: In 2015 LVM Studios will release the Apollo Saturn Launch Umbilical Tower. Source: NASA At Scale Model World 2014 in Telford UK (11/08-09/2014) LVM presented a prototype of their BIG LUT Project, Source: LVM Studios which will be available in three different scales: 1/144 for the Revell Saturn V or Airfix Saturn V 1/96 for the Revell Saturn V 1/72 for the Dragon Saturn V This is definitely a spectacular and very challenging project, only question is what price will be called for these kits ...

    Apollo Saturn LUT by LVM Studios 2015

    Hello everybody, once again in memory of the beginning of the LVM LUT project in 2014, when € 14,271 was funded by the backers, and the LVM promise: From November 2015 the model kits will be available from our dealers and distributors. Kickstarter's Terms of Use 4. How Projects Work that govern the agreement between creators and their backers, reads: The creator is solely responsible for fulfilling the promises made in their project. If they’re unable to satisfy the terms of this agreement, they may be subject to legal action by backers.
  10. Hello everybody, once again to the Track shoes that Joe has put on thankfully. There's nothing like a good technical drawing with measurements, even if they are just so on the limit of readability. Now he has to downscale the Track shoe "only" still to 1:160, whereon I'm really curious. While the holes in the Pin lugs (Ø 3,3 '') with Ø 0,5 mm (1:160) and the 0,4 mm (1:160) wide grooves (green) should still be printable, the small holes (pink) with Ø 0,2 mm (1:160) should unlikely to be printable, although one should be able to live without them, because later they are hardly recognizable anyway from a normal viewing perspective. Now I'm curious what Joe will be able to do, whereby Shapeways has the last word anyway.

    You will see, Pete, this frustration just makes you still tougher ... Chin up, chest out! Hold on tight to your dreams and keep it up!
  12. Hello everybody, today, still a supplement to the 3D-Intertanks. Meanwhile, Michael Key still also offers a further modified Airfix-IT. And that is the Early SLWT, which was flown since the STS-91 (ET-96), which here is presented in the new Shapeways Design. Source: shapeways.com (The Aerospace Place) For this he only needed to modify a few details on my previous IT, which he thankfully has done too. Here once again the front side with the 26 Integral Ribs and the 7 Circumferential Ribs in the Thrust Panels, etc., and here the back with the Graphite Composite Access Door and the Vent. This configuration of the Early SLWTs was flown up to the STS-107 (Columbia disaster), starting with the STS-114 the PAL Ramps were omitted at the Late SLWTs, and from STS-122 then also the 7 Circumferential Ribs. There are now three versions of the Airfix IT (1:144), my Early LWT, which is now on its way to me, and next to the Early SLWT also the Late SLWT, all of which can be found here both in WSF as well in FUD.

    Apollo Saturn LUT by LVM Studios 2015

    Hello LUT community, as it looks like LVM seems to have switched off their lights, especially because since a few days one cannot reach the LVM website anymore. Also my attempt to reach Leon van Munster via email at store@lvm-studios.com was unfortunately in vain: No valid MX hosts found!!! This inglorious end according to the motto: It's better to make a painful break than draw out the agony ... is for all, but especially for the LUT backers, to whom I unfortunately also count, in addition to the financial loss in total a huge disappointment. That's not the fine Dutch way, Leon ...
  15. Hey Joe, and that on empty stomach early in the morning, that really floored me. Thanks my friend, you are a hotshot! That's really jaw-dropping! Hopefully there will still something be remaining of it after downscaling to 1:160 ... This is how the Track shoes look in David Maier's Paper Kit (1/160). P.S.: I've asked Joe if he could design a 3D model for these Track shoes in 1/160 for my Crawler, of which one needs 456 pieces, Source: NASA and he has delivered promptly.

    Do you remember, when I had tested Gator's Grip for gluing a handrail? That was truly fun!

    1/24 GEMINI 9A part 2

    Hi Pete, why do you want to solder, take Gator's grip, which is usable for brass to brass, plastic to brass, stainless steel to plastic, stainless steel to brass, and even plastic to plastic!
  19. Hello everybody, there are enjoyable news. Fortunately Michael Key had compassion for me and has modified his 3D model of the IT, so that I can save me the painstaking post-processing of the Thrust Panels by using my mini-saw, which I had tested about a week ago. Here is his 3D-Update of the flown STS-6 tank ET-8, which is now to be found at Shapeways under its new name Early LWT. Source: Shapeways (The Aerospace Place) Before this action, I noticed still just in time that at his previous model still lacked two small details that I had previously overlooked. So far I had mostly only ET photos of the side facing the shuttle, but hardly any of the opposite side. Source: retrospaceimages.com (J. L. Pickering) There I was always fixated only on the Access Door and the Carrier Plate Assembly. But also on the back there are exactly opposite the same two items as on the front side, as one can see in this photo from George Gassaway. The pink circle involves the RSS Antenna and the blue circle an aerodynamic Vent. Source: georgesrockets.com And exactly these two items were missing on the back of my IT, which of course could not stay that way, wherefore I should have to scratch them if necessary. But these two things Michael Key has kindly complemented next to the modification of the Thrust Panel Ribs, so that the IT now is perfectly matching the Early LWT. Source: Shapeways (The Aerospace Place) And this IT I have ordered now once more in WSF and will probably use it in this form for my ET. BTW, the IT modeled for my friend Mike (crowe-t) for his STS-135 (ET-138) Shuttle stack is offered at Shapeways under Late SLWT.
  20. Hello everybody, let's go on with the analysis of the SOFI Rings. Since my first count of the rings on the LO2 Tank on this ET-8 photo seemed to be a bit vague and upto the top was incomplete anyway due to the lack of resolution, Source: retropaceimages.com (STS-6) I repeated the count again today on this new (old) photo of the ET-8 because its resolution is much better. Source: forum.nasaspaceflight.com (Jester) For this I had set the zoom mode (MS Word) to 250%, where one can see the rings pretty well, and came up to 66 rings. And that would have to be roughly the area, where at the Airfix-LO2 Tank, which is 81,5 mm long, the front Nose cone cap is put on, the tip of which unfortunately broken several times and must be replaced. With this the determination of the ring widths was made, or in slightly more complicated expert wording, the Valley-to-Valley distances: 81,5 mm : 66 = 1,2 mm, which agrees well with the value of 1,3 mm for the rings determined on the LH2 Tank, and would match also from the optical impression. Unfortunately, in the photo above, the Nose cone is covered with foil, but in the following image one can see different cones on LWTs of the first generation (1988), whose shape is interesting for scratching, Soure: forum.nasaspaceflight.com (Jester) and therefore here once more a slightly larger section. And already thereon one can see that the Nose cones of the LWTs looked a bit different, than one knows them in Graphite composite version from the last missions with SLWTs.

  21. Hi everyone, today I glued the first few tape rings of the 1 mm tape onto the ET dummy, but that was not for the faint of heart. Since I still haven't got the 0,5 mm tape as a spacer, I have taken an Evergreen Strip 0,25 mm x 0,5 mm, whereby the difficulty is to position this very thin strip around the tube, in order to stick the 1 mm tape strip beside it. After having tested and rejected some holding methods, I came up with this Magnet sling, wherefore I clamped the strip at both ends between two small magnets and put it over the tube, which may seem adventurous, but still have worked. And in a similar way I would now have to glue 170 of such strips in case of emergency onto the LH2 Tank, whereby the 0,5 mm tape as a spacer should be a great relief. And to such an emergency I really have to adjust myself now, because Michael Key today has given me a knock-back for reasons of time. He means that he has only little time and would need it to spend on projects that are financially worthwhile for him. He would have the feeling that only the front ET part (LO2 Tank) would take a lot of development time, with the prospect, possibly to be able to sell only a few of them. He had also hoped that the IT for the STS-135 SLWT for my friend Mike (crowe-t) would be a quick and easy conversion, but also that was turned into a time-consuming project with several modifications. Unfortunately, I have to accept his decision, so I will now fully be focused on my Scratch variant with those tape-rings and by using the Flour technique for the SOFI texture.
  22. Hello everybody, meanwhile, the 0,75 mm masking tape has arrived, whereby I was lucky and got the last role. The 0,5 mm tape is unfortunately not available at this dealer, as it is no longer offered by his source in England, which is why I have ordered it now in the Sockelshop, where even 0,3 mm tape is offered. Then I tried the 0,75 mm tape on the LO2 Tank to see if or how it sticks to the curved surface. For this I have marked an orientation line and then glued the tape next to it, which is quite feasible, as it clings well to the curvature. If I then have the intended as a spacer 0,5 mm tape, then I can make the test on the ET-dummy, whereby I would need to use 1 mm tape, since the 25 m of the 0,75 mm tape would be needed almost completely for the 130 rings on the LH2 Tank and are reserved for it.
  23. Thanks my friend, the adventurous trip can go on. After I have also revealed the last secret of the STS-6 ET-8, I know now what it must look like and I just have to realize it still somehow.
  24. Hi everybody, in my search for more Hi-Res photos of the ET-8, I came across another great rollout photo here in NSF, even though with a laughing and a crying eye. At first glance, one can still see no details at the Intertank in this resolution, but the picture is also from the thread Michoud: Best of External Tank - Hi-Res Images of Jester, and that's why the zoom finally provides information about the so far hidden detail structure of the Thrust Panel, which surprised me quite a bit. Source: forum.nasaspaceflight.com (Jester) Thereon one can clearly see that these panels of the first LWTs had no circumferential rings and bars, how I let them modeled by Michael Key for my IT. That means that the Intertank, which was modeled by Michael Key for me and since then offered by Shapeways, is no LWT-IT but an early SLWT-IT. My mistake was that at that time I was too inspired by the 3D Intertank of my ARC friend Bill (niart17) and had not researched thoroughly enough. Thus, this is another example of the "curse" of the late pictures, one could almost say, what I had already happened one time at the very beginning, only this time with the difference that I have surprised myself. BTW, even in this photo one could already see this Rib structure without the circumferential rings in the zoom. Source: forum.nasaspaceflight.com (Jester) And also my only STS-6 photo with a view of the Thrust Panel actually indicated that already, although I was not sure yet. Source: forum/nasaspaceflight.com (woods170) Anyway, now I know about it and just have to think about how I handle it now. As you may remember, my two ITs look like that, whereby I really liked these Thrust Panels. But these seven rings and small bars did not exist on the ET-8 at the STS-6 and are therefore out of place. These rings existed only since the transition to the SLWTs since STS-91, but were then left out again since STS-122. What is to do now? But anyone who knows me a bit closer, knows that I can not be satisfied with that, which is why I was looking for a workable solution. And since the grooves between the ribs are very narrow and flat, my mini-saw of CMK (cmkkits.com), was the perfect choice, which is only 0,1 mm thick, With that, I carefully removed the bars between the grooves, which is cumbersome and requires the utmost caution, but is ultimately feasible, which at least my first test on a wasted IT has shown. And with the steel ruler one can then even later smoothen something. In principle, a modification of Michael Key's 3D model would be possible, but the master is currently absent, and if I could get it that way, it would be okay and also cheaper. Consequently I'll probably have to bite the bullet and try to get it right on my Stack-IT, toi, toi, toi!!!
