Thanks Mike for your enthusiasm, which I am very pleased. These small details in this small scale cost a lot of time and some do not succeed the first time. I wonder sometimes and say, this can not be true, where is this little part? Only a small episode, not the first time that happened to me. The other day one of the two double ROFIs was suddenly gone, I thought I was going crazy. I have searched until the floor and found nothing, then on my desk and found nothing. Then I thought, I'm going to have to build this tricky ROFI again. But then I had the saving idea, maybe he is slip

Hello Pete, thank you for your honest words of appreciation, each of us likes to hear. I am impressed by your models as well and have already received many valuable suggestions, wherefore I thank you especially. I'm lovin' 'em too and can't wait to see more of your art!

And now the last cut only follows, then this supply line is finished, and can be tried together with the ROFI. As you can see, the front end is still too long and needs to be filed down slightly. But as the two parts fit together already quite well. Now the same procedure is carried out only laterally reversed for the supply line at the LH2-ROFI as long as the work routines are fresh.

Hello folks, and here we go, the same parts I needed again for the second front ROFI. For the second base plate I first had to make a new punching tool, and then bending the supply line and cutting rings for the union nuts. Before fitting the rings I have this slightly widened. And then I have the supply lines modified and adapted a bit. After that I have bent on the TSM-template the inner line from ​​0,4er copper wire, where I proceeded step by step. The difficulty here is that the supply line is relatively small and must be made two bends in tight spaces. Thus, the followi

Bill, already your paper prints of the interface details look great and fit very well. Can not wait to see the 3D prints on the ET. Your work inspires me again and again, it is an amazing and innovative level in Real space modeling, which you are presenting here. Thank you for sharing with us.

CAD should one can, you're meanwhile a jack-of-all-trades, Bill!!!

Today only a small update. As I suspected, the supply pipe of the front ROFI is actually slightly inclined angled down to the TSM wall, as you can see here pretty well in this picture. Source: NASA But I'm still not quite satisfied with the first prototype of the front ROFI. That's why I now have clarified and added some details, and these are now the final parts of the front ROFIs. I hope that the two small cap nuts are still visible, if not, just the magnifier can help. The first round connector plate (made ​​of paper) was yet a little too big, because with 0.4 mm wire diameter t

Hello Guys, let the sparks fly, these ROFIs hold me up quite nicely, but I pull now through, with or without ignition wire. Therefore, here comes the second front ROFI before I'm out of practice. Thus the ROFIs now would be half finished, only missing the feed pipes on the rear side. And so now I have made ​​further with the front ROFI of the LOX TSM. The pipe is made ​​of 0.4 mm copper wire that can be bent nicely. And the little gray disc becomes the connecting plate of the pipe. Since the front ROFIs only have a relatively simple pipe, I will install this now but before pai

F A N T A S T I C !!!

Hi all, I want to briefly report how it went with the ROFIs. Meanwhile, I have completed the rear ROFI for the LH2 TSM according to the same procedure. The gluing of the supposed spark plug wire I have for now postponed. Since I'm namely not quite sure if that really are during launch off or not, especially since there are also pictures where the cables are not implemented. Source: NASA Therefore, I have asked at the overseas friends (NSF Forum) whether maybe someone can answer. Perhaps the ROFIs are armed ​​only before the launch and inserted to the igniter with the cables etc..

Thanks Bill for your nice compliments. You also build a MLP for your stack 1:72? Come on, let's see! This is of course a more comfortable scale for scratch building these and still other tiny details. So Nothing ventured, nothing gained.

And already at this distance, you can see that one can hardly recognize something from the small tubes, and later of the little wires certainly even less ... But the heck with it! In close range you already can recognize and that's enough for a quiet conscience.

Hello together, so now I have to go to the sleeves and small tubes, and later perhaps also to the little wires in these tubes, of which here already one (0.08 mm) is threaded in the right tube, actually, but probably hard to see, right? Next, the sleeve was glued with CA on the base plate, which appears oversized from this near anything, so do not be fooled. And here's the fitting on the LOX-TSM. So far, so good. But before I now insert the mini-tubes, I started with the holder of the LH2-TSM. To fix the center bar this time I have taken a mini-magnet which is more practical th

Hey John, Have you engraved the tiles?

Hello Bill, fascinating details, looking great. You are doing pioneering work in the use of 3D printing parts, congratulation.

Hello folks, and this madness could also be topped and would even remain in scale. As you can see in the picture, from the inner tubes are running still thin wires, I suspect ignition electrodes of the spark generator, or something like that. Source: NASA I have now made ​​my fun and estimated its diameter. If I take the diameter of the inner tube with 0.5 mm as reference, the wire diameter should be around 0.08 mm. And introduce yourself, I've actually found in the thinnest litz wire (0.6 mm) I have, a very thin copper wire of this diameter, hard to believe, but true !!! Such a sma

Hey Hotdog, you give such a lot of effort with tis stuff, but the surface quality of the Shapeways SSMEs is underwhelming, to put it mildly. In comparison, I like that much better of RealSpace Models.

In this form, the holder can also be handled much easier, as here at the fitting on the LOX-TSM. And also during painting the longer center bar is very practical as a holder. Then arrived just in time the ordered brass tube Ø 0.5 mm for the inner ROFI tubes, whose optics I've tried the same times as compared to the brass wire (0.5 mm), as you can see here. Although this is only a tiny detail that will probably barely recognizable at the model later, but it corresponds to the real thing much better than the wire.

Hello together, let's go on with the next update. First, I have separated the sleeves (1.8 mm) with the Dremel cutting disc, which I've left a few tenths as a precaution supernatant. For cutting I have kept the ferrules on both sides with toothpicks and slowly brought up to the cutting disc. Although I am going again proceeded with extreme caution, the first sleeve piece is flown away shortly before cutting, never to return, :blink: what could possibly have been due to low speed. In the second experiment with a much higher speed it worked well even better. After I had filed down the su

Outstanding progress, I knew that you will solve the problem somehow, really cool! Do you want to smooth out the frayed edges of the medical tape yet somehow?

Hi Mike, now but please don't be overmodest, your attention to detail is also impressive and I like it. And now to the umbilical connections, although the parts of the umbilicals are very filigree, as you can see here, left the LH2 umbilical, and right the LOX umbilical, Source: capcomespace.net I will try if I can simulate it somehow. But that will probably be a pretty tricky stuff in 1:144, I could imagine. So the umbilical parts looks in the paper kit of David Maier. Maybe I build the umbilicals as pluggable connectors (green) that I can take out even if I want to show the MLP

Hi folks, now I know a little bit more abaout the ROFI details. During detailed definition of the dimensions I unexpectedly found still new close-ups from a different perspective on which I could detect and measure the ROFI details more clearly. It has struck me suddenly that the holders of the rear and front ROFIs distinguish. While the rear holder has a U-shaped construction, which I was not previously aware, Source: NASA can be seen at the front holder that this only has a slanted stiffening up, and down is open. Without this knowledge I had built this holder U-shaped too. Sou

Hi Pete, this re-entry wear looks very impressive.

Hello guys, today only a short remark. The prototype of the ROFI looks not bad, but it seems to be slightly oversized. Meanwhile, I have the dimensions specified something else, thereby the sleeve becomes slightly shorter, whereas the final styrene construction will make the holder something of filigree. And for the pipes I'll use 0.4 mm copper wire instead of 0.5 mm brass wire. Then the ROFI will certainly better fit for the TSM design.

Hi Pete, the hairspray weathering is a cool technique for representing wear and gives the model a typical appearance after a very long time out of service. This is a new and great inspiration for me, from you we can always learn great stuff, thank you for sharing your skill and experience with us.
