mikephilippens Posted April 29, 2020 Share Posted April 29, 2020 Again, your attention to detail is beyond belief... The 'barberpole' pattern is a very precise job, but I fear that putting on the strips on the front/bottom of the tank will be even harder bacause it's not a straight surface. How are you going to approach that? Cutting out strips for one 'revolution' at a time or do you apply that barberpole pattern there too? I'm anxious to see the results.

The Underdog Posted April 29, 2020 Share Posted April 29, 2020 Manfred, Once again, your "attention to details" and being able to translate them into your build are phenomenal. No doubt whatsoever, you're going to have the most accurate build - and your work on the ET is just part of the overall equation, and the results! Quote Link to post Share on other sites

Thanks Mike for looking in on me and for your nice words. Also onto the LO2 Tank I will stick a barberpole style endless tape spiral, and I think there will be no problems, because the 0,75 mm tape is so thin and flexible that it will nestle easily against the tank bulge. Cutting out and gluing separate strips for each 'revolution' would be a too brutal punishment, which I would like to save myself. This typical SOFI pattern texture can be clearly seen in this photo of the ET-33 (STS-36) by George Gassaway, Source: georgesrockets.com and also on the LO2 Tank of the ET-8, which interests me, on which I had counted the number of rings, which was the purest stress for my tired eyes. But my previous attempts gave me courage to try it again now. The only difficulty is maintaining the same spacing while the tape spiral is being glued, but I hope being able to do this crazy job successfully. Let's wait and see, and keep your fingers crossed for me. Quote Link to post Share on other sites

spaceman Posted April 30, 2020 Author Share Posted April 30, 2020 (edited) Hello friends, I've tried it on the Aft Dome, which is actually not immediately satisfactory, since the 1,5 mm tape on this flat bulge with decreasing radii is increasingly difficult to bend and consequently fits less smoothly, which then leads to small wrinkles, which of course do not appeal to me. A little remedy can be provided by carefully cutting into the wrinkles with the razor blade and then pressing them flat, which I did here in the middle area above the Man Hole. But that's also not yet exactly brilliant, I think at least ... With the 0,75 mm tape, this should probably look different on the LO2 Tank, i.e. a little bit better.

mikephilippens Posted April 30, 2020 Share Posted April 30, 2020 In Dutch, we have this expression 'monnikenwerk', which translates to monastic work (Klosterarbeit). It refers to the tedious work the monks did in copying books by hand. This qualifies as monastic work at Olympic level... Quote Link to post Share on other sites

I think a lot of us have been trying to find the proper, "Superlatives" in describing what Manfred has been doing with this project, since the beginning. You have found a new and unique way of putting it, connecting it to 'Old World' practices in getting it done! I for one, have learned to expect the unexpected... not knowing and being surprised at what he is capable of doing, with his talents and this project. Quote Link to post Share on other sites

spaceman Posted May 1, 2020 Author Share Posted May 1, 2020 Hello everybody, today fitting to the topic of SOFI Pattern Texture, here once again a small quiz question. Most of you already know this item on the right, this is a piece of SOFI Insulation Foam from the External Tank ET-138 flown on the last mission, STS-135, that my friend Scott Phillips has gifted me. But what could that be on the left in the picture? Quote Link to post Share on other sites

spaceman Posted May 1, 2020 Author Share Posted May 1, 2020 Hey Underdog, Bingo!!! This is a piece of a Heat protection tile from the Thermal Protection System (TPS) used for the Shuttle, which a friend from our Raumcon Forum has gifted to me as a small present from his visits to the KSC, with which he made a great pleasure to me. If one takes the material in hand, one will immediately notice the low weight, which is no wonder with a pore content of approx. 90%. This is a complete TPS tile that has a top layer of Borosilicate that withstands temperatures from 1200 to 1600 °C, underneath there is this material of sintered Silica glass fibers (SiO2), of which now a piece enriches my rarity collection. Source: wikipedia.org Source: wikipedia.org And to match this, the following two spectacular videos demonstrating the amazing properties of this material. This photo is already a little taste of it.

spaceman Posted May 2, 2020 Author Share Posted May 2, 2020 I was also thrilled, especially since the effect is so amazing and overwhelming, that one does not believe one's eyes. That's jaw-dropping! Quote Link to post Share on other sites
spaceman Posted May 3, 2020 Author Share Posted May 3, 2020 Hello my friends, in the meantime I have still thought and tried out another variant with two 0,75 mm tapes glued next to each other, which intuitively should work better on the flat curve of the Aft Dome. After I had removed the previously glued 1,5 mm tapes, this time I started on the inside at the smallest ring and first of all glued the 0,75 mm tape from the roll on the marked circle, piece by piece, and always firmly pressed on tightly, with the tank in the left hand and the tape roll in the right hand. Then I glued the next tape ring right next to the first ring, which was a bit easier because the tape did let easy nestle to it. Since from now on it was important to keep the spacing of the double rings as uniform as possible, I glued four small pieces of the 0,75 mm tape as a spacer for better orientation and then glued the next ring, relying on my sharp eagle eye during the following quarter turns, until the next spacer came into view. And so I've laboriously rolled out ring by ring, which was quite a torture for my eyes, so that I had to take a few breaks. And then it was finally done, and I was done too, and the result is actually as I had imagined it and looks well, in my opinion. With these positive impressions I went to bed early in the morning ... And here are still a few pics in daylight. This time indeed it was twice the effort, but the heck with it, it was worth it ... The Lord of the Rings says hello and wishes all a nice Sunday.

K2Pete Posted May 3, 2020 Share Posted May 3, 2020 🤣 The Lord of the Rings indeed! Such a wonderful ... yet very time consuming ... effort, Manfred!! I can only imagine the strain your poor eyes endured ... it's nice that you treated them with a well deserved rest! Quote Link to post Share on other sites
The Underdog Posted May 3, 2020 Share Posted May 3, 2020 Manfred, I'm so glad you've taken on the responsibility of, "Elevating the Bar" to such a lofty level. It's a Win-win all-around, you're happy with the results and we get to enjoy witnessing a "Phabulous" project such as this... the likes as never seen before! Quote Link to post Share on other sites

But that was nevertheless just an easy exercise in comparison with the job on the rest of the ET with its felt 1.000 rings ... What will I say afterwards yet?
