  1. Hello everyone, today in a quick way some images of the gluing of the three remaining Screw Jacks without many words. After gluing the Gear units onto the fixed Base plates (0,13 mm x 1,4 mm x 1,5 mm) the Folding bellows were glued onto the Worm gears one after the other. And here they are standing in rank and file like the tin soldiers, and can next be glued onto the Double angle holders.
  2. Thanks Kirk, no problem, your joke regarding the fully working Space Shuttle system I've understood especially since it's tantamount to a compliment. The only thing I haven't immediately understood was the Tracking and Data Relay Satellite (TDRS-A) in Challenger's payload bay. Source: retrospaceimages.com (STS-6) But since I'm only building the closed payload canister, I didn't have to deal with TDRS-A. So all you have to do is imagine that he's in my canister, if you want so.
  3. Hello everybody, this was followed by gluing the lower small cross struts (0,25 mm x 0,5 mm x 1,5 mm) at the end of the vertical frame struts. For the gluing of the Diagonal struts I had to scroll back and look at the special arrangement of the steel rulers for fixing. Due to the modest artificial light conditions, I've set up my improvised Object lighting with a Headband LED, which, together with my Headset magnifying glass, gave me the perfect view. For the gluing o
  4. Hello everybody, I can be honest, it is a new challenge every day to sit down at my craft table because I know what is waiting there again for me ... A little fun on the side. In our German forum, a friend was astonished at that my components are narrower than the protruding edge of the 1 Cent coin. And if he really means the width of the protruding edge of my constant companion, then according to the current measurement it is 0,46 mm wide, which shows, that some of my parts are meanwhile smaller indeed. Today I was satisfied with
  5. Hello everybody, and thus to the Folding bellows, their assembly sequence I've quickly recapitulated in my former post (Posted January 21). First, I glued the Lifting spindle protective tubes into the holes in the Double-angle holders. In order not to break off the already glued tiny Angle holders on the sides, this time I clamped the holders at the front and back between the rulers, as well as aligned their seat in scissor tweezers and let dry. This was followed by the well-known tricky threading of the black rubber
  6. Hello everybody, for the remaining three Screw Jacks I came up with a different solution. In order not to have to glue the tiny Angle holders to the sides of the Double angle holder last, which was a pretty tricky affair, I have this step this time brought forward. That's why I first drilled the holes for the Spindle protective tubes in the brackets, first with Ø 0,3 mm pre-drilled, and then with Ø 0,5 mm re-drilled. Then the sides were beveled, wherefore this time I fixed the holders between four rulers and then cut
  7. I can also still clearly remember the horrified faces of President Ronald Reagan and his wife Nancy ...
  8. Dear friends, on this memorable day in 1986 with the Challenger Mission STS-51-L took place the first launch from the just finished Launch Pad 39-B, Source: wikimedia.org which ended in a disaster 73 seconds after lift-off, in which the seven-person Challenger Crew lost their lives. Front: Michael Smith, Francis Scobee, Ronald McNair; Back: Ellison Onizuka, Christa McAuliffe, Gregory Jarvis, Judith Resnik Source: wikimedia.org Let us take pause in silence and keeping their legacy alive forever.
  9. Hello everybody, an exact re-measurement of the small angle holder on the double bracket of the Screw Jack resulted dimensions of 0,4 mm x 0,5 mm, which is why I did not use the initially selected 0,5 mm wide strip, as I would have had to cut 0,4 mm long strips from it, which is almost impossible to do it reproducibly. So I've cut a new strip out of Evergreen Sheet Styrene (0,13 mm x 0,4 mm), although it was difficult to get the width (0,4 mm), which took me several attempts. This gave me the advantage that I could set the length (0,5 mm) on the ruler and
  10. Thanks Kirk for your nice compliments, I sometimes marvel at myself what crazy things I keep coming up with ... As long as you guys like them and don't make bored, it's all okay and I can keep going on the long and winding road ...
  11. Thanks Kirk for your nice compliment, you are such a loyal soul too, still following me ...
  12. Thanks Bruce for staying tuned over the years and for appreciating my photos, that's remarkable. I'm attaching great importance on this indeed, although it takes a lot of time, especially to photograph these tiny things well and sharply, which is not easy every time. Especially white plastic parts have too little contrast, and shadows in artificial light during my midnight sessions are also very annoying. Then I also like to use my little Euro Cent friend, but it mustn't be too close to the object, otherwise the auto-focus of my digicam will focus on it and the obje
  13. Thanks SG for your short but nice compliment, I'm amazed myself that I usually manage to do it the way I imagined.
  14. Hello friends, so let's continue with the remaining struts on the frame for the Screw Jack. After all four top frames were done, the vertical struts were glued, for which the frame had to be fixed again in order not to be able to slip, which can otherwise happen very quickly, whereby had to be rechucked again and again. The test fitting on the sketch fits quite well so far, and the frame so far looks stable too.
  15. Hello everybody, well then let's get to the tricky Double-angle holders, on which the Worm Gears are mounted, which I've cut with the Chisel cutter from my prepared H Profile to 1,7 mm length. However, since the shape of the sides of the angle is not an isosceles triangle, as can be seen in this image, Source: NASA (STS-125) I first had to attach these unequal slants to both sides of the tiny one, which was quite difficult because one can hardly fix the angle for it, but I managed to do this to some extent with the cutter and car
  16. Hello everybody, meanwhile I've been thinking about how I could scratch the tiny Worm Gear and the Folding Bellows as well as the encased Coupling Rod, sitting on top of it. For clarity, this time I've left out the confusing scaling of dimensions and just given the final dimensions of the components, making it easier to see the details to scratch. Source: NASA (STS-132) Then I looked around for suitable materials and found some in my inventory, including a suitable black insulating tube Ø 1,4 mm for the slightly thicker lower area of the bel
  17. Hello everybody, a far trickier component is this pivoted Double angle holder onto which the Worm gear is mounted, which functions as the drive component of the Screw Jack which provides the vertical movement of the trapezoidal spindle. Source: NASA (STS-135) Tricky therefore, because this double angle is very small, as one can imagine from its dimensions (1,7mm x 1,5mm x 1,0mm) in this image. Source: NASA (STS-125) Therefore it would be a clever solution if there was a suitable Styrene profile that would fall within this rang
  18. Hi Kirk, it can't be due to the chamfer on the cutter blade, as I deliberately use a Chisel cutter (Martor) whose blade only has a chamfer on one side, and which can therefore be ideally placed at the ruler edge with its flat side when cutting. But even here it is important to guide the chisel cutter as vertically as possible, because the slightest skewing would result in a faulty cut again. But it's good that you reminded me of my Mitre Cutter (RP TOOLZ), which I actually only use for larger quantities, like back then for the felt like 1.000 pins of the Crawler chains
  19. OMG Pete, I feel for you, I would be frustrated too and I would go through the roof.
  20. Hi Kirk, definitely, these are my standard methods meanwhile. My compliments, you have a good sense of proportion too, which is nearly the same measure what I also would read off. And so to the background of my estimation question. For the frame struts of the Screw Jacks I will use Evergreen Strips (0,25 mm x 0,5 mm). Since the frame is only 2 mm wide, the gap is 1,5 mm, which is why I need a total of 8 snippets of this length. Therefore I initially set the steel rulers exactly to 1,5 mm, but I was surprised that the
  21. Hello everybody, speaking about measurements with a steel ruler vs a digital caliper. Only a short question, especially for my friend Kirk. What do you think, how long will the snippets be that I can cut with this ruler setting using my cutting method with the steel rulers?
  22. Thanks Kirk for your joky comment, you'll laugh, but that's exactly what I'm doing every day, which is why I'll show you my plastic ruler and my digital caliper. But that shows me that you're not such a loopy scratch builder like me. Since I measure the distances on the monitor, the plastic ruler is the much simpler, better and, above all, faster tool, with which I can measure with an accuracy of up to 0,5 mm without any problems, which is completely sufficient for the selected photo enlargement. OMG, that's why I wouldn't drea
  23. Hello everybody, and I tackled that right away, which resulted in the following dimensions. Source: NASA (STS-135) In order to keep track of it myself, I marked the determined heights and widths in color, especially since they also were determined by using different reference dimensions (blue). As reference dimensions I've used the dimensions of the Wall braces of the door actuators, which are identical to those of the Screw jacks. But that's still not all the dimensions I need. A few widths from a front view of the screw jack
  24. Hello everybody, and now the Door actuator followed for the other canister side using the same knitting pattern. With this the Port Side now also has its door drive. Next up are the bottom linkages of the Door actuators on which the Screw Jacks are mounted. Source: NASA (STS-135) They are similar to the adjacent Access Platforms in terms of the structure of the mount, but are much narrower and therefore a bit more complicated, as one can see on this section at higher magnification,
