Thanks Underdog, bow.gif

 

now nothing must not go wrong with the Flour Applicaion, so keep your fingers crossed! JC_doubleup.gif

 

I just have still to think about how best to do this, whether I spray the two tank parts individually with spray adhesive and then powder them with flour, or whether I completely glue the tank together and mask the Intertank ... smiley215.gif

 

Somehow I have to hold the part/parts, both while the spray adhesive is being applied and during the subsequent flouring. hmmm.gif

 

What do the experts think about it? :hmmm:

Hello everybody

 

meanwhile I have decided not to flour the two ET Tanks separately, but to glue them together with the Intertank beforehand, which should make handling easier. cool.gif

 

EbRdDO.jpg

 

And for the Flour application I have in mind a horizontal mount similar to the Test rotisserie, einfall.gif for this I'm going to insert the aluminum rod that was already in use through the front Nose Cone opening, which reaches to the Aft Dome. This rod then is clamped in a side holder so that I can turn the tank around its axis during spray gluing and flouring, whereby I will first flour the LH2 Tank, and then the LO2 Tank.  up045518.gif

Before gluing of the three ET parts, I had to mark the exact position of the 12 Ice Ramps (R20) on the LO2 Tank in order to be able to cut out and mask their contact sites, taking the exact alignment of the GO2 Press. Line up to the Nose Cone had to pay attention, which was not so easy to do. smiley_worship.gif

Afterwards I've marked the position of the Ice Ramps with the help of the Newware template,
 
RiFmOk.jpg

 

and then were cut them out.

 

YJ9CMZ.jpg

 

Then I had noticed for a longer time that the Newware Ice Ramps are rectangular (3 mm x 3,7 mm), and not square like the original Ramps. rolleyes.gif These have the dimensions 1,5' x 1,5', which corresponds to 3 mm x 3 mm in 1/144 scale, which is why I will adjust the ramps accordingly, what has already happened with the front ramp. top.gif

Then I've yet masked the contact areas and the front part of the LO2 PAL Ramp

 

jqK2no.jpg

 

Thereby however, I had not considered that the PAL Ramp is right next to the Cable Tray (0,5 mm x 0,75 mm) and therefore has to be a little wider, huh.gif which I've  corrected after I had put on the channel for better orientation.

That's it again for the moment. Thanks for watching and have a great Sunday.  up040577.gif

Hello everybody,

 

so friends, now it's getting serious slowly, because the final Flour application is getting closer. yikes.gif

 

After I had unrigged the entire ET and freed it from all lines, I've first glued together the Intertank with the LO2 Tank,  

 

v0vd3j.jpg

 

and then also have glued the IT together with the LH2 Tank and removed the SRB Support bar.

 

Then there were some smaller places on the LH2 Tank, like the openings for the two Vertical Struts of the ET/Orbiter Aft Attachments and the LH2 Feedline, as well as for the ET/SRB Aft Attach Struts, which is done meanwhile.

 

After that there were left only the lower parts of the LO2 Feedline Supports, which I've  taped with 1 mm tape so that I didn't have to clean them from the glued flour in order to have uniform contact surfaces for gluing the Feedline. cool.gif 

 

de0R0d.jpg

 

Then I still have taped the Manhole Covers

 

jCscAO.jpg

 

and the openings for the LH2 Recirculation Line and the Diagonal Strut were closed with toothpick tips. smiley228.gif

 

BKjncD.jpg

 

Since I will first flour the LH2 Tank, I then have completely taped the Intertank and the LO2 Tank,

 

k1tQUl.jpg

 

in order to be able to easily turn the ET when spray gluing and flouring. I will try out the holding device for the Aluminum rod tomorrow and then present it.  up045518.gif

 

Sw2Sh2.jpg

 

Well, and these are one by one the necessary utensils for the upcoming Flour Action, the UHU Spray adhesive, the Rice flour, of which I've bought a new pack to be on the safe side huh.gif and a new can of Vallejo Primer (white). top.gif

 

TbNt5Z.jpg

 

Next I will think on and test the Holding jig, and then I only have to overcome the inhibition threshold for the Final countdown, of which I'm scared a little bit because nothing must go wrong. eek.gif

 

And therefore please keep all your fingers crossed, dear friends.  JC_doubleup.gif

Hello everybody,

 

and now to my new jig for the Flour coating of the completely glued ET, which inevitably had to look different than in my first test serieses, when I could horizontally insert the Holding rod with the dummy and let easily rotate around its axis both during the Spray gluing as well as during the Flour coating. cool.gif

 

up067846.jpg

 

For holding the skewered ET I have now chosen this modified arrangement, in which the holding rod is plugged into an upright standing cardboard. 

 

z5sBaC.jpg

 

Since the aluminum rod has sagged too much when the ET was racked, I had to replace it by a more stable Bamboo rod

 

l3ajGM.jpg

 

This gives the ET a better grip, 

 

jGWtN4.jpg

 

whereby it can be easily turned with the left hand when spray gluing and flour coating. smiley250.gif

 

LAeUHV.jpg

 

With this the first part of the ET's Flour coating should work well, I hope so.  top.gif

 

After priming then the second part can follow, for what the masking on the LO2 Tank is removed, after which the LH2 Tank can be floured and primed. up040577.gif

I discovered spray welding this week.
This looks a very similar method.
Can't wait to see the completed model

 

Thanks Pete, bow.gif

 

but this method my ET would not survive ... eek.gif

 

Better not! up040577.gif

Hello everybody,

 

in view of the occasion, here is a little side leap to the meanwhile almost unrecognizable Launch Pad 39A, on which in the meantime Elon Musk with his company SpaceX is at home and had planned a historic thunderbolt yesterday. yikes.gif

Certainly, many of you, like me, waited eagerly for the start of the SpaceX Demonstration Mission 2 (SpX-DM2) last night, but due to the unfavorable weather conditions it had to be canceled and rescheduled to Saturday. rolleyes.gif

 

Here is an image of the crew, Douglas Hurley (left) und Robert Behnken.

Matching to this here is an image of my friend Scott Phillips with the DM-2 Commander Douglas Hurley with one of his legendary Hardwood Shuttle Tribute Models after the last Shuttle Mission STS-135, in which Doug Hurley participated as a pilot of the Atlantis. In the image on the right is Michael D. Leinbach, the then Shuttle Launch Director of NASA, including STS-135.  smiley250.gif

So far, Scott "Shuttleman" Phillips has created more than 450 such one-of-a-kind handcrafted wooden shuttle models from a wide variety of wood types to reflect and honor the execellence and legacy of the Shuttle Program, and had let many of them signed by the shuttle crews at the time, of which he is very proud. up040577.gif

Th eright stuff but they are no Bob and Mike.
I got up early to watch the launch. Maybe I should have stayed in bed and it would have gone off.

Hello friends,

 

now it was finally time and I was able to position the ET in the flour chamber for his countdown. top.gif The spray adhesive I had previously placed  in a warm water bath and then shaken it vigorously again so that it can be sprayed easily. 

 

kP0p4H.jpg

 

Then once again a short test grip with rubber glove and next door a few test sprays on a cardboard that were okay and gave green light. cool.gif

 

d7mQRp.jpg

 

Afterwards, the LH2 Tank was sprayed under repeated turns and at the Aft Dome and then a photo was quickly taken. smiley192.gif

 

aXtW02.jpg

 

And then the flour dusting came in ... 

 

3ukH0a.jpg

 

and it was generously applied all around with the sieve and lightly pressed down with the finger,  up045518.gif

 

mffbjX.jpg

 

while the ET was turned several times. 

 

kChnLG.jpg

Then it was enough with the flour dusting and the excess flour could be shaken off by tapping lightly.

Then I went into my office and was able to have a close look at the preliminary result, which looks pretty nice so far. speak_cool.gif 

 

Now everything should dry properly before the remaining flour can be brushed off.

And then the flour layer can be fixed with a first primer coat.

Let's see what the result looks like after brushing. up040577.gif

Thanks Mike and Joe, lob3.gif and keep cool and curious. 

 

And now, based on the hit by Silver Convention - Fly, Robin, Fly (1975) ... up035091.gif

 

Dry, ET, Dry!  up040577.gif

Great work Manfred. Nice to know that the tank is suitable for vegans - which may keep Gino from being tempted to take a bite.

Once again, your attention to detail is second to none.

Hello everybody on Whit Monday,

 

after the spray adhesive has certainly dried, I've picked up the soft long-haired brush and carefully brushed off the excess flour. This was followed by a gentle Peeling with a pointed tweezer, with which small lints were removed. cant-believe-my-eyes-smiley-emoticon.gif

 

And this is how the LH2 Tank now looks after the Flour coating. top.gif

I'm very satisfied with this result, so that the priming can follow now.  up040577.gif
