  1. Hello everybody, here is still a small addendum to a detail on the Port Side, where below the Personnel Door is still located this Access Platform Mounting Bracket, which I have added. Source: NASA (STS-125) The Bracket (0,13 mm x 7 mm) stands on tiny Base plates (0,13 mm x 0,5 mm x 1,5 mm), whose gluing together was quite tricky. Here is the test fitting on the canister together with the two ECS Ducts. And then there are still these Horizontal Transportation Tie-down Lug Plates
  2. Hello everybody, and after the same knitting pattern briefly to the announced ECS Supply Duct, for which the Pipe bend on the Connection nozzle has to be glued rotated by 90°, wherefore the parts on the right are already prepared. To the left is the finished ECS Return Duct. After the Connection nozzle was glued onto the Ring plate, came the decisive step, in which this time the pipe bend had to be glued lengthwise with the foot of the connection nozzle onto the ring plate, which was then glued lengthwise onto the bas
  3. Hi Al, here you can seen the real walkway mesh and determine the mesh size of a better suitable grid. Source: nasatech.net Maybe such a 40 Mesh stainless steel grid. Source: mallametalica.es
  4. Hello everybody, and thus to the shortening of the Tube turns for the two ECS Ducts, whose dimensions are summarized here again. Source: NASA (STS-104) In view of the small dimensions of the arches, it quickly becomes clear that after cutting the bent round rods (Ø 2,5 mm) to the different lengths, not much of them will remain, what becomes clear after the cutting marks been attached. A firm fixation is required for cutting through the rod, which is why I clamped it in the Mini vise (Proxxon). Then the marking was carefully scor
  5. Hello everybody, and thus to the ECS Supply and ECS Return Ducts of the canister, which are connected via the red hoses to the Environmental Control System (ECS Module) of the transporter. It's starting with the two white Connecting nozzles firmly connected to the canister with the Tube bows welded from five segments, whose dimensions I've determined from this photo. Source: NASA (STS-130) There one can see that the connecting nozzles sit on thin Base plates (0,13 mm) and that the tube bows are attached to nozzles with Clamping rings, which
  6. Thanks Mike for your nice words, well, Real Space Modeling is my great passion and works like a drug, from which I just can't get away, especially since I keep discovering new and interesting details of this ingenious technique. But don't worry, a possible infection with this virus is completely harmless.
  7. Hello everybody to early hour, today is a memorable day in the history of manned US Spaceflight, because on April 4th, 1983 Space shuttle Challenger took off with its crew on its maiden flight STS-6, Source: retrospaceimages.com (STS-6) L-R: Donald Peterson †, Paul Weitz †, Story Musgrave, Karol Bobko Source: wikipedia.org to which I have dedicated my long-term project, with which I'm going already into the 12th year.

  8. Hello everybody, now that the Handrails are safely stowed away until they are glued, I once again looked at the various doors, hatches and instrumentation panels on the canister. Although these are only small optical details, they give the canister its own face and should not be missing. From these details I then printed out true-to-scale copies from original photos and glued them on. First, there's this Personnel Door on the Forward Bulkhead of the canister, Source: forum.nasaspaceflight.com (STS-9, Ares67) which has to be tight and therefo
  9. Hello everybody, and these Mounts were glued today. At it the most difficult step was pushing the Handrail feet into the tiny mounts, which is why I "sharpened" them slightly. Then the gluing followed with MEK by carefully wetting the mounts with the finest red sable brush (10/0). This also finished the third Handrail pair, and could be placed on the template for fitting. It was finally the turn of the last couple, whereby the whole set is f
  10. Hello everybody, today the Mounts were glued to the other three-legged handrail, wherewith the row at the bottom of the canister is complete. Then it was the turn of the two vertically arranged handrails above it, which have two mounts and were done more quickly. And so the image slowly completes, whereby I also still hinted the Personnel door through which one can arrive the Canister Payload Bay. Now only the mounts on the four upper railings are missin
  11. Hello everybody, and with it to the Final Cutdown. This was the chosen arrangement for the second half of the brackets for cutting off the U-profiles (1 mm) that I had previously scratched and marked with a pencil, here after careful cutting with a razor blade under sharp eagle eyes. And that's my valuable yield of 20 mounts (2 reserve) with approximately the same size. I had imagined the gluing of the mounts onto the handrails to be a little easier, but firstly it turns out differently, and
  12. I've been saving started posts (text & jpgs) in MS Word for a long time, better you have, than you would have.
  13. Hello everybody, let's go on with the production of the tiny Handrail brackets, which are held up the progress quite a bit, since you always have to let the glue dry before you can handle them any further. In the meantime I have arranged the steel block the other way around when cutting off the end strip, as this way I can better control the cut with the razor blade. The tricky separation of the U-profile can also be done in different ways, which is why I tried out a few things and switched to a larger sheet of steel as a base, whi
  14. Hi Al, that looks good already, keep it up and don't give up, even if it gets tricky anytime.
  15. Hi Mike, you are one of my most loyal companions all time and I know you've been in there from the start, which is why I looked back. That was 11 years before almost to the day (03/15/2012), what a long and memorable time to look back on fondly. And you were the second interested modeler after Bill (niart17) to reply that time. You also recognized early on the difficulties of the scale dilemma and raised concerns about the size of the SRB Blast chambers and TSMs that I only later realized after the Shuttle stack was test set up on the MLP. And that then led to the fir
  16. Thanks Mike for your staying interest in the background. I can understand you, what should you keep writing again and again too about such a long time ...
  17. Thanks Mike for looking in on me again after a longer time.
  18. Hello everybody, is there anybody in there? And thus to this new variant for the production of the Handrail brackets that I have been thinking about. The idea behind it is actually simple and based on the production of such a U profile with a greater length, from which I then carefully cut off small 1 mm long pieces and close on one side. Thought and done, gluing the side strips (0,13 mm x 0,75 mm) to the base strip (0,25 mm x 0,5 mm) took place again in the proven manner by fixing between the rulers. Such a Steel ruler is also
  19. Hello everybody, originally I had immediately thought of my narrowest Evergreen profiles, but both the H profiles and the U profiles are 1,5 mm wide, which would not match to the filigree handrails. Then I've compared a Channel profile (1,3 mm) with my planned four-part variant (right), which, when using strips (0,2 mm x 0,75 mm) for the sides, is approx. 0,9 mm wide, which looks more pleasing in combination with the round rod (Ø 0,45 mm) of the handrail struts. And if I would cut a Styrene strip (0,13mm x 0,75mm) for the sides, it should loo
  20. No problem Kirk, 1:160 is a little bit smaller, if you want so from the Underworld. The dimensions determined from the NASA drawing are decisive, whereby the blue dimension (diameter of the handrails) is my reference dimension. BTW, please ignore the blue 12, it comes only from copy and paste.
  21. Hi Kirk, thanks for your tip and that you have ruminated about it and want help me. I've immediately thought of my narrowest Evergreen profiles too, but both the H and U shapes are 1,5 mm wide, which doesn't match the delicate Handrails. Then I took a Channel profile which is 1,3 mm wide and compared it with my version (right) which is 0,9 mm wide, using 0,2 mm thick strips for the sides, which looks like this. I think if I would cut a strip (0,13 mm x 0,75 mm) for the sides it should look still a little bit better, still closer
  22. Hello everybody, well, the smaller the details to be scratched, the closer you have to look to see their shape and being able to determine the needed dimensions. As you can see in this image section, the Holder sockets are in the form of small U-profiles in which the handrails are articulated. Source: forum.nasaspaceflight.com (STS-9, Ares67) Since this photo shows the canister used during STS-9 (11/1983), it can be assumed that these Handrails and Ladders already existed at the time of STS-6 (04/1983), but unfortunately I don't have any dir
  23. Thanks Kirk, I do what I can and always try to find the best doable solution.
  24. Hello everybody, and thus for gluing the remaining two Handrail pairs, again using the proven method, here first Handrails G-3, and here Handrails G-4. And here is the obligatory test fitting atop the template that I like. As already mentioned, however, all Handrails on the feet also need similar mounts like the Outriggers, so that they can be erected or folded up as required. And these are 18 pieces, which should become similarly tiny.
