Hello everybody,
 
in the meantime I had thought over, that it would certainly be difficult to remove the paint on these fragile sickle holders, especially since the contact points should be clean for a good adhesive bond.

And that would mean that the fragile sickle holders would have to be sanded gently, which would presumably not happen without breakages.

But I've already considered whether I should not paint the spaces between the sickle holders with a fine brush by hand ...  

I have not painted anything with Airbrush for a long time, which is why I'm simply unsure whether such horizontal surfaces below the ring line would get enough paint. Furthermore the paint application has to be well dosed, which is why several thin layers are advisable and too much paint at one go should be avoided.

Because I would bite myself somewhere else if I would spoil my painstakingly scratched details by an unclean varnishing ...

Hello everybody,
 
and because we have dealt with breakages, of which I had to complain already some at the ring line outlets, without damage the last action with the clamping rings unfortunately had not ended.
 
On closer inspection, I have noticed unfortunately that the small nipples on the outer two 6'' outlets behind the TSMs after the felt 100.000 twists and turns when clamping the ring lines must have been broken, which I had not noticed so far.
 
That is why, for a change, cosmetic operations were announced today, because something like that bothers me, even though it would hardly be noticed by somebody else's.
 
These OPs are, however, rather delicate, since the outlets are only thin round bars ( 1 mm), into which still thinner rods (0.3 mm) have been glued as nipples. That is why I have first carefully sanded off the remaining stumps and then still more cautiously drilled small holes with 0,3 mm, but for which I first had to think on a clever clamping condition of the ring line for a stable support.
 
Seek and you shall find, and here the nipple rod is already glued again with a little overhang, which now only needs to be shortened accordingly, what but also does not so easily go out of cupped hands.
 

 
For the cutting off the supernatant then a different support had to be found and to be newly clamped again,
 

 
so that the rod also has a stable support and can not break off.
 

 
But that worked out well,
 

 
as one can see here.
 

 
And the same OP then synonymous still at the other ring line, as before.
 

 

 

 
And so the damages have been remedied again.

How did you make the pipes using plastic? The way they are shaped? I'm planning the same for my 1/72 scale model. How did you get the pipes to bent into curves like that?

The word Thank you seems to be a foreign word to you, right?

Hello everybody,

in the last few days I have finally brought myself to start with the gluing of the Pipe Supports under the ring line behind the LOX-TSM, for which the already announced removal of the rear SRB Supports was necessary.

Since I can carry out the gluing of the supports only step by step, in order to be able to check their seat, I have to remove the ring line now and then, and because I did not want to risk anything, I have removed the disruptive rear SRB Supports.

For gluing of the pipe supports, the ring line was then introduced again and its exact seat fixed with the spacers. After that, I tried as a first variant the gluing with MEK and have initially positioned and aligned only three supports under the ring line, as well as dabbed the contact points of the sickle holders on the outer side carefully with a fine brush with MEK, which should be sufficient for a first hold.



And as one can see in this picture, that was actually already sufficient. 



Since in the bracket-holder I can reach now the remaining contact places of the sickle holders from all sides, I can now also glue them completely.   
And so it can then gradually go on with the next supports.

This is looking amazing, how do you have this much patience?

Thanks Ian for watching! 

All you need is will of iron, nerves of steel and years-long exercise, as well as the strong conviction that the dream will come true someday ...

Hi all together,

for the gluing of the next Pipe Supports I used again my approved bracket-holder in the mini vise, which is best suited for this.

With this I have much more freedom of movement for the assembly and can adjust the position of the ring line so that the already attached three Supports lay flat on the support block and I can push the next supports below the line by slightly raising and arbitrarily align. 

Then I also modified the gluing technique, whereby I carefully dab the normal Revell plastic glue onto the sickle holders with a acupuncture needle, then push the support under the raised ring line and then lower it. This allows for even smaller position corrections until the support sits in the right place. After that, the ring line is still weighted down, so that it can be fixed firmly on the spot.

Then I can then take the mini vice with clamped ring line in the hand and stabilize the sickle holders also still from inside and outside with MEK, which should give them the final hold.

And this technique I have here exercised with the two Supports behind the corner bow, which also worked great.





And in the same way it went on down the straight line.









And now they hang in rank and file and look  .



Then came the three flatter supports sitting on the Blast Shield, which I have glued with inserted ring line.





And finally, I have glued the small support under the 16'' rejuvenation behind the LOX-TSM, which has only one sickle holder. 



So I want to let it go for today.

Not to mention lots of free time!

I look forward to you finishing the piping and moving on to other interesting aspects of your build.

Thanks Oersted for looking around,

that's right, scratch-building of lots of such tiny details is undoubtably a very time consuming process, or with other words maybe a never ending story ...
But this SSWS pipe and support madness is now coming to an end, slowly but surely.

Hello everybody,

today I want only present a few pictures about the gluing of the six Pipe Supports on the inside of the ring line behind the LOX-TSM, which took place in the same way. 









And tomorrow it will go on with the gluing of the first six triangular supports (left) at the outlets of this ring line,



which hopefully will work similarly well.

Hello folks,

as hoped for, the gluing of the first three triangular supports went smoothly, as can be seen in the following pictures.







And then the three supports at the outlets on the inside of the ring line had their turn.







So far so good, now I need to repeat the same procedure only still on the other ring line behind the LH2-TSM.
