      PhotoBucket are no longer permitting 3rd party hosting   01/07/17

      As most of you are now painfully aware, Photobucket (PB) are stopping/have stopped allowing their members to link their accumulated years of photos into forums and the like, which they call 3rd party linking.  You can give them a non-refundable $399 a year to allow links, but I doubt that many will be rushing to take them up on that offer.  If you've previously paid them for the Pro account, it looks like you've got until your renewal to find another place to host your files, but you too will be subject to this ban unless you fork over a lot of cash.   PB seem to be making a concerted move to another type of customer, having been the butt of much displeasure over the years of a constantly worsening user interface, sloth and advertising pop-ups, with the result that they clearly don't give a hoot about the free members anymore.  If you don't have web space included in your internet package, you need to start looking for another photo host, but choose carefully, as some may follow suit and ditch their "free" members at some point.  The lesson there is keep local backups on your hard drive of everything you upload, so you can walk away if the same thing happens.   There's a thread on the subject here, so please use that to curse them, look for solutions or generall grouse about their mental capacity.   Not a nice situation for the forum users that hosted all their photos there, and there will now be a host of useless threads that relied heavily on photos from PB, but as there's not much we can do other than petition for a more equitable solution, I suggest we make the best of what we have and move on.  One thing is for certain.  It won't win them any friends, but they may not care at this point.    Mike.

Fantastic enginuity. It always seems that the first try exceeds my expectations, yet you strive for something more precise every time. That will make this build the best ever...

Hello Mark, my faithful companion, and thanks for your continued interest and the joy of my work. lob4.gif

I think the best is just good enough and so I'm often striving for the perfect solution, no matter what kind of material is needed and how long it takes, because only the result is important, and nothing is impossible. up040577.gif

Hello everybody,

 

before starting with the rounding of the longer gutters according to the new method with the plastic core strip, I have tried here the lateral gutter end from a rounded rectangle strip 0.25 mm x 1.5 mm. cool.gif The strip will be cut off only after gluing.

 

ERkDB0.jpg

 

But now to the longer part of the Gutter 1, which was pre-rounded first in the largest half-pipe (Ø 7.5 mm) with an aluminum core (Ø 4.0 mm). 

 

PIfASk.jpg

 

And this went on in several stages with diminishing diameters of the semiconductors and core wires, starting with 

 

Ø 6,4 mm, 

 

VhR6ft.jpg

 

Ø 6,0 mm,

 

XLMhDI.jpg

 

Ø 4,7 mm. 

 

tcwaxK.jpg

 

down to Ø 3,0 mm.

 

lODFrP.jpg

 

The following rounding with the plastic core strip (1.75 mm) was then carried out on the foam strip,

 

R6EBtX.jpg

 

and then by pressing it together in the Balsa "vise".

 

aNMBMH.jpg

 

And then it went on with the 1.5 mm core wire on my "pin board" using my Balsa-Clamp technique, with which I have bent already the SSWS pipes. top.gif 

 

By cleverly clamping, the core wire can be held down with the inserted gutter, while at the same time in the interspace the gutter wall can be smoothed almost perfectly by swaying the balsa board back and forth.  speak_cool.gif And by re-clamping the arrangement one can also reach the previously covered areas of the gutter for smoothing them.

The rounding could then be further smoothed on the other also rounded side of the core strip by pulling a fixed rubber over the gutter rounding. cool.gif

And this is the result of all this tender loving care, top2.gif

 

hzOS79.jpg

 

eV0fCn.jpg

 

which can really be impressive and so is also taken from the quality control of the FSC. top.gif

And since I now know the fact how it works, I can calmly dedicate myself to the other gutters. up040577.gif

Hello everybody,

 

let's have a short break, because I have got an interesting post by a nice fellow (DaveS) in the NASASpaceFlight.com Forum, who has written as follows ...

 

Manfred, I have found something that will require you to go back a few steps. It concerns the grid structure on the north walls of the SRB exhaust holes. It isn't launch equipment. It was in fact a temporary support or bracing structure for the walls when MLP-2 was undergoing some rebuild work back in 2004. I have attached a photo from STS-135 which was MLP-2's last launch which clearly shows that the structure isn't there.

 

together with this image.

 

rwYfk4.jpg

 

Here is a better photo of his stumbling block, what hasn't been surprising me, because I have seen lots of such images already, and I know them very well ... up035091.gif

This refers to my previous rear walls of the SRB Exhaust Chambers, as created by David Maier, which can be seen here at the adaptation of the Water Bags.  rolleyes.gif

 

up056232.jpg

 

In connection with this this image of a SSWS Test (2004) on the MLP-2 was always on my mind, on which these rear walls are to see.

At some time I had even scratched these grid structures,  speak_cool.gif 

 

XMdZWT.jpg

 

which unfortunately had fallen a victim to my emergency surgery for the adjustment of the SRB shafts , but which I have kept so far.  happy.gif

 

But since I decided to install the Water Bags, I had to renounce it for reasons of space and therefore I used the rear walls from the Paper Kit. 

 

Interesting would be the question to David Maier, why he decided for these rear walls ... nixweiss.gif

 

As an explanatory answer, I sent DaveS the above picture of the SSWS test and said that the back walls also looked like this after the conversion of the MLP-2 in the year 2004 and probably also before were not different, but what still turned out as a fallacy. huh.gif

 

When viewing the image series of this SSWS test in NASA Media Archive was clarified to me by the detailed information that 2004 some equipment at the MLP-2 were converted or exchanged, as can be read there ... 

 

This test is being conducted following the replacement of the six main system valves, which had been in place since the beginning of the Shuttle Program and had reached the end of their service life. Also, the hydraulic portion of the valve actuators has been redesigned and simplified to reduce maintenance costs.  

 

especially because the Shuttle missions after the Columbia Disaster (STS-107, 2003) were interrupted for a year and a half.

 

And in his following answer, DaveS has also confirmed that with two pictures for me comprehensibly. cool.gif

 

In this image of the STS-90 (1998) the known structure of the rear wall of the MLP-2 is to see,  that means before the overhaul in 2004.

This image of the STS-115 (2006) shows the same structure of the rear wall in closer detail in the rear SRB shaft.  cant-believe-my-eyes-smiley-emoticon.gif

And if one looks at the following image from the overhaul phase, this frame structure was, in my opinion, should be the uncovered substructure of the rear  wall, onto which the standard wall cladding was installed again after the overhaul, which was the same on all three MLPs. 

 

up017445.jpg

So I guess that the rear walls of the MLP-2 at the STS-6 at that time also looked like this and I have to redecorate my rear walls accordingly, but that is no problem, because I still have copies of it. top.gif

Then let's go on,

 

of course this was reason enough to mend matters right away, which is gone, is gone! cool.gif

 

Here one can see once again the old, but wrong rear wall (right) of the SRB shaft from the Paper kit, which is now to be exchanged by a piece from the area on its left, which is suitable very well. speak_cool.gif

 

TVMK8L.jpg

 

Here, the two new rear wall panels are already cut out, 

 

0ouo2J.jpg

 

which were immediately tried on the "High seat", but please with greatest caution! schlaumeier.gif

 

xlbT7r.jpg

 

And that looks very well already, top.gif

 

jeU4t8.jpg

 

YVTwle.jpg

 

and also gives a completely different picture, that I like much better. top2.gif

How good that DaveS has still raised his hand, although late, but not too late. up040577.gif

Hi Manfred, just a quick aside... is that Schumacher's Ferrari I see next to your computer monitor? I have a kit of his F1-2000 still to build, from the year he clinched the title in Japan on the last race of the season... I already made the figure of Michael with the decals from 2000. Not quite on the same level as your NASA research, but quite painstaking nonetheless.

 

Back on topic... the SSWS looks great and the back wall does look very nice.

yes, it is Michael Schumacher's Ferrari 248 F1, as you can see here on a very old photo five years ago ...

The new chamber walls do look a little more pleasing.  Not as much visual tension, a cleaner look.  Good call.

Especially the rear walls are now true to the original, what is crucial. up040577.gif

Hmm Schumacher. I know that name from somewhere. Wasn't he No. 2 driver at Mercedes before Lewis joined?? :P

 

Mind-bending model by the way. :D

but sorry, are you pulling my legs? That hurts ... 1-13768.gif 

 

If you speak in riddles about Michael Schumacher, then I would have to ask, who is Lewis? LOL.gif

Didn't mean to cause you pain Manfred. :sorry:

I'm just one of those people who suspects that Michael (brilliant as he was on a driver) is flattered a little too much by the record books. For much as I remember that amazing race (I think it was Spain 1994) where he came second in the race in the wet with only 5th gear, I also remember Adelaide 94 and Jerez 97 and Monaco 06 and so on - incidents which were not fitting of a man with his talents. 

Lewis is the chap who is going to win the F1 driver's championship this year. :penguin:

 

Enough of this diversion though - keep building!! :whip:

Hi Kirk,

 

I knew that you only were kidding me, top.gif your smiley unmasked you. :P

 

But now back to the stressful gutters with their tiny supports,

which I want to scratch today. up040577.gif

Hello everybody,

 

let's go back to the gutters and their supports. cool.gif

 

These were the first patterns,

 

9mjIZC.jpg

 

whose proportions were still too inaccurate to me.  rolleyes.gif  

 

MAIr3y.jpg

 

That is why I have checked the dimensions more precisely with the aid of this photo since I had not considered some of the perspective distortions so far, cant-believe-my-eyes-smiley-emoticon.gif which inevitably lead to errors. 

 

QpUQEB.jpg

And afterwards I drew this template with the new dimensions to get an accurate overview.

 

I7Lfi8.jpg

 

And as one can easily see, there is nearly nothing to be detectible in the scale 1:1, but in 5:1 one can see it much clearer, and so the shape could then also be approximately right.  top.gif

 

This is now the new support that should fit to the gutter dummy,

 

2jQ0HQ.jpg

 

which could fit well.  speak_cool.gif

 

ozkeSw.jpg

 

And with that I could go into the mini-production, I think, or are there objections or any hints? denknf8.gif

 

But maybe the lower part is still a bit too high ... hmmm.gif

Hello friends,

 

in hindsight the lower part seems almost a bit too high for me, if I look at other pictures. undecided.gif

But perhaps it is only an optical trick of light & shadow and the viewing angle, because the lower flange always covers a part of the height. denknf8.gif
