Space Shuttle Launch Pad 39A with Challenger STS-6 (1:144)

Hello again,

but initially the 9'' outlet still received a few small details.

At the feedpoint of the 24'' ring line is a small thickening to see, for what I have punched a small Styrene disc (0.5 mm) with Ø 1.6mm, which has already been glued, as can be seen in the following figure.

Due to the small diameter of the outlet of 1.4 mm also the diameter of the nipple is correspondingly smaller with only 0.3 mm, for what only a tiny hole were to drill,



into which my thinnest rod with Ø 0,3 mm was glued. Next to it is a lead wire with a diameter of 0.3 mm, which I will use for the clamping ring on the other end.





The lead wire I have glued with CA.



And so the final outlet looks, from which I still need a second copy.



And now to the slender support pillar, which stands under this outlet and consists of six parts,

which I have already prepared and are all quite tiny,



which must be glued together now.

And I can tell you, the mounting should become a tricky matter due to the minimal contact surfaces.



Since I glued these things with normal Revell glue for possible corrections, one can not continue, but must wait until hardening.



And the height of the support I should also check from time to time, since it should not exceed 9 mm in order to fit even under the outlet.



And for that reason alone every now and then a break is necessary, like now, why the base plate and the top plate have to wait.

Hello everybody,

and here is the next update.

Since I still wanted to check the total height of the support pillar, I have not initially sanded the tiny rounding in the upper pipe holder, especially since it is anyway only 1 mm x 1 mm "big".

The problem with this prototype is, that the height of the components should be exact as possible on the tenth of a millimeter, if in the end should be reached the calculated required total height of 9 mm, so that the support fits under the transition.

Subsequently, the support was positioned on the base plate and glued,



and then vertically aligned on all sides vertically.



And so the filigree structure looks, which is very fragile and wherefore the further handling is to enjoy with caution.



With the optical look of the support I am already very satisfied, although actually still missing these two screwings,

which I wanted to try at least times. In my estimation, one could scratch it by thin rods, which would, however, which would be again in the boundary region of the nipples with Ø 0,3 mm.

That would be even doable, although this strip (0.37 mm x 1.5 mm) is slightly wider than the only 1 mm wide plate under the pipe holder,



and through the shadows it could be seen even better in the painted state, questionable would be, however, from what distance ...



But more important is the question whether and how the support would fit at all.

And to my surprise, it fits already together relatively well,







although the left side of the pipe hangs a bit in the air, as can be seen more clearly in this close-up.


But this should be still compensable if I sand even a tinier rounding in the tiny pipe holder (1 mm x 1 mm) and it plays along.

Although this support was quite tricky, this looks but overall very well.

Hi there,
making of the tiny rounding was not a problem, especially since only a hint of 0.15 mm was necessary.

And here is the result,



and because the transition now sits a little bit lower, so far everything is okay.



Therefore, the rounding of the second pipe holder will be made before assembly.

I've been following this thread along just in awe and amazement at your level of detail.

[spacerunner]

Thanks whulsey for your kind words.
These small details are quite tricky, cost a lot of time and therefore I can progress only slowly, but the effort is worthwhile.

Hello together,
despite the interesting divertissement by the Olympics the SSWS pipes were continued in the meantime.

Today, the second 9'' transition was scratched, which had to be bent again initially.





Although the processes are now already familiar, the difficulty is to make the transitions as identical as possible.



These are the individual parts up to the two rods for support pillar.



After the filigree U-shaped substructure has been scratched, the difficile assembly of the parts followed, which was quite stressful again.



And so the couple was complete,



and could be tested on the MLP.

Although the provisional fastening of the outlets with Pattex is also such a tiresome game of patience and does not long hold out,





for the imposing overall impression the effort is worth to me, which is why I have brought out the Rainbirds again.





So much for today.

Incredibly detailed work as always Manfred

I'm gonna nominate you for a PhD. in Pipeline Planning & Construction Manfred!

Thanks elliott for your nice proposal.
The SSWS is really a tricky chapter, but I must bite me through, the end is in sight.

Thanks PE for watching,

I try giving my best.
