  1. Hello everybody, first, I've beveled the strips (0,13 mm x 0,7 mm) for the lateral retaining struts at both ends with the cutter chisel, wherefore I used a small template, which had suffered quite a bit. Then the different length strips (0,25 mm x 0,5 mm) have been glued to form a frame, whereby first the longer strip (3,5 mm) was glued against the shorter strip (2,5 mm), whereto steel rulers served as a guide and for fixation. Then the second side stripe was glued, and finally the other narrow side, wherewith the first of four frames was done. And then the second frame was glued in the same way. Next, these two frames are glued together using four support struts (2 mm) to form a frame box.
  2. Hello everybody, just a quick reminder of the Challenger Rollout - STS-6 in the fog 40 years ago. Let's Keep the Legacy Alive!
  3. Hello everybody, from this disastrous false start of our kickers against Japan I had to recover ... I didn't get much further either yet, only the base plates for the grab rails on the doors are now glued with MEK. Perhaps the grab rails are painted before gluing. Next I took a closer look at the lower Door Actuator linkage and the Pneumatic Drive and determined the required dimensions for the scratch build, which again should become tricky. Source: NASA (STS-135) The brackets for the lower linkages are similar to the Access Platforms, only they are a bit narrower. In between runs the drive shaft connected to the Pneumatic drive, by means of which the lower linkages are extended to be coupled with the upper linkages in order to open the doors. In this photo one can see the entire arrangement again in the top view. Source: NASA (STS-114) Let's see what profiles I can use for the individual parts.
  4. Hello everybody, and from NASA's huge SLS Moon rocket back to my crafting table and to my little puzzle pieces. In fact, the smaller the pieces get, the smaller and slower the steps I take along inevitably get, but I have to get through that now. For the sake of completeness, I would like to add one small but important detail for the safety of the Can Crew, and these are these Grab rails here, which are next to each upper Door Actuator where members of the Can Crew could hold on themselves or buckle their protective belts. Source: NASA (STS-132) In order to roughly fit my scale (1:160), I used NiCr wire (Ø 0,15 mm) and tried to bend grab handles out of it, which wasn't that easy, since they should only be 1,7 mm long and 1 mm high, so they are tiny. For my first attempts I've bent the wire step by step over three 0,5 mm thick steel rulers. However, the first four bending attempts (left) were not satisfactory because the handles with 2 mm were too wide. For more reproducible widths of approx. 1,5 mm (right) I've later modified my bending technique. Here, however, a handle is inserted into the door as a test, which has not completely convinced me, as the handles are still on a narrow base plate (0,1 mm x 0,6 mm x 5 mm), which I initially wanted to omit. But with a brass angle (wall thickness 1,3 mm), narrower handles with a width of approx. 1,7 mm could be successfully bent, which I already rather was more satisfied with. But then I've still decided to try scratching the tiny plates and used my thinnest Evergreen sheet (0,13 mm) for this, into which I've drilled holes with my thinnest Twist drill (Ø 0,25 mm), in which the handle also has fit. First I've drawn the shape of the narrow plate around it, and carefully cut out. The remaining plates I've pre-drilled using the template, and then cut to the final shape. Luckily I only need four of these base plates. Now I have to see if I'm able to carry on during the Soccer World Cup as I've done before. We'll see ...
  5. Hi Richard, well, as far as the SLS Rocket and the Mobile Launcher are concerned, I'm curious if and when the first kit will come out ... One should never say never.
  6. Hi Theb, maybe I should greet you with Welcome to the Machine! in memory of a track from Pink Floyd's great album. Source: quora.com Wow, such an extraordinary compliment for my work I have never heard, but shows me your appreciation and enthusiasm. Well, I'm a bit too tall for a nanobot at 1,78 m, but at least ... what a nice joke! But I must confess, in order to get that level of detail at such a small scale you have to be pretty crazy already ...
  7. Hello everybody, wow, what a spectacular picture-book launch of NASA's SLS Moon Rocket with the Orion Spacecraft atop to its maiden flight Artemis 1 that leaves you wanting more. Source: NASA
  8. Hello friends, before the Artemis 1 will take off in about 5 hours, if everything goes well, here is a short report on the platforms. Here are the already known steps for gluing the individual parts of the platforms. Finally it's done, and I can glue the platforms to the side walls with UHU-CA, here first on the Port Side, and here on the Starboard Side. And here's a member of the Can Crew checking a Door Actuator. And now I'm thrilled to bits for the Artemis 1 Lift-off.
  9. Hello everybody, extreme caution was required when gluing the Door Actuators onto the Payload Bay Doors, which is why I haven't glued the filigree support struts for now so as not to take any risks. The gluing was done with UHU-CA, first on the lower rotational axis of the stand-fork, and then with MEK at the sickles, which resulted in sufficient adhesion. Only then the support struts were glued at the upper rotational axis, first on the Port Side Door of the canister, and then at the Starboard Side Door, wherewith a difficult and tricky subassembly was completed. In order not to have to constantly take the canister in my hand during further assembly work and to protect it, I put it down on a small cutter mat. Next followed the four Access Platforms on the side walls, which can be climbed over the ladders when the canister is in a horizontal transport mode, in order to mount the linkages of the upper and lower Door Actuators to be able to open the doors. Source: NASA (STS-125) Source: NASA (STS-132) Of course, it is much easier and, above all, safer from the lifting platform. Source: NASA (STS-126) Here I have already prepared the necessary individual parts, the platforms (0,5 mm x 3,5 mm x 4 mm), as well as the different support struts (0,25 mm x 0,5 mm), the gluing of which will then follow next time.
  10. Hello everybody, but of course this needs to be well thought out so that nothing goes wrong with these fragile parts. Strength lies in calmness. So that the linkages first get a certain stability, I first glued the lower stands between the sickles, for what they have to be fixed somehow gently, wherefore I've used a longer tape strip. Then the stands were carefully grabbed with the pointed tweezers at the axis of rotation between the middle struts, both ends dabbed with a drop of glue and pushed between the sickle ends, where they were aligned a bit. And when you see them lying there, it all looks pretty easy. And if one knows how it works, one only needs to repeat it. Now I only have to cleverly glue the linkages onto the doors, in order to then finally glue the support struts.
  11. Hello everybody, the coupling forks for the remaining three support struts I'm now also still able to do. But first I wanted to give the remaining four sickles their final shape in order to glued them to the upper rotary axles (Ø 0,3 mm), which was stressful precision finishing work that I had to trudge through. Then the 3rd couple of sickles was glued, and after that it was finally the turn of the last couple. And after cutting off the overhang, all four couples were done, and I could take a deep breath. Finally, the remaining three coupling forks and their gluing to the support struts still waited, for what I've taken my time. And to get this fragile odds and ends off the desk before it disappears again or gets damaged, I will now glue the linkages onto the Payload Bay Doors.
  12. Hello everybody, and now still a short look for the return of the “Bermuda Triangle” in my room, whereon Graspaps had pointed out. The whole time the remaining three support struts were always on the table in front of me. I was all the more surprised today when I looked at my desk and saw that there were only two struts left. I thought I couldn't see correctly and I immediately suspected that evil forces were at play again and I remembered the said "Bermuda Triangle" ... However, since I couldn't find the 3rd strut on my desk, I immediately looked at the floor directly in front of me and started searching on my knees, but couldn't see anything of the sort, which got me more and more frustrated ... After pushing my chair aside, I searched the wider area. Lo and behold suddenly I spotted the strut in the "Bermuda Triangle" on the floor, about 1 meter away on my left beside my chair, was jolly glad and put it back on the desk to the other two struts. I don't know how it got there, it was probably hanging on me somewhere and fell off there ... It certainly won't be the last time, slowly I'm experienced in finding lost things ...
  13. Your Tracy Island looks very futuristic. Hello everybody, the remaining three support struts were produced in the same way as described lastly. During the drying I brought the second sickle pair to the final shape. After cutting off the strips on the support struts, both sickles were glued with the rod (Ø 0,25 mm) for the upper rotational axis, then the excesses cut off, and smoothed the ends. Then I tried my hand at a coupling fork and have carefully slit the spacer (0,7 mm x 1 mm), which was used lastly for making the stand fork, on the narrow side with a Fine saw blade (CMK), and widened the slit with fine sandpaper. But since this strip with 1 mm is too thick, I would have had to cut it in half or grind it down, but I didn't want to do that to myself. That's why I slit an Evergreen Strip (0,4 mm x 0,7 mm) in the same way. To cut off the only 1 mm long coupling fork, I secured the slotted end with tape to prevent it from jumping away. From that point of view, the fork could even be a bit narrower ... To glue it to the support strut, the fork had to be fixed again. And then I wanted to know it and try to display the unfolded state of the linkage. To do this, I carefully inserted the strut with the coupling fork between the stand fork, and carefully lifted it with a razor blade, which was pushed under it, and erected up to the point, until the end of the support strut hit the upper rotational axis, which was pure thrill. And after a few failed attempts, I actually succeeded in this game of patience. In contrast, I will build the canister with folded Door Actuators, for which purpose the individual parts are then glued together, which will make assembly much easier.
  14. Thanks Hans for your nice compliments. Hard to believe you have been scrolling through all 96 pages! For that alone you deserve my STS-6 Endurance Medal 1st Class. On your journey you should also have come across the image of this mini diorama (1/700) from Tomytec on p. 81, whose base plate is only 35 cm x 29 cm "big". Source: Andromeda24.de My Diorama of the Launch Complex 39A (1:160) could look something like this, on the other hand it is supposed to be 160 cm x 90 cm. Strange, what a coincidence, related to the “Bermuda Triangle” there is a current event, which I will briefly discuss in the next post. Therefore stay tuned. BTW, I've also checked out your interesting website and saw how versatile your talent is, really impressive. This reminds me of the Miniatur Wunderland in Hamburg that you may know.
