Hello everybody,
but now hold your hat! Hard to believe but wonders will never cease!
Somehow, this idiotic rejection of the upright standing Set of 20 with flat-lying shoes did not convince me and therefore did bother me.
And as befits a real Challenger, I went on the offensive and ordered the Set of 52 - Flat Ori - Come hell or high water,

and chased then curious the course of the order.

And even though I had already expected the same rejection, my order at SW went against expectation through their process chain Processing, Pre-Production and was then actually In Production, I thought, I do not see right.

And today I got the email Shipped!, which has blown me away.   I have actually outsmarted them, unbelievable ...

Now I'm curious what the set looks like, at which the shoes with the treads lay on the support wax.

Hello everybody,

today, the 52 Set-Flat Ori (FUD) came as if there had never been any problems with printability. Unbelievable, but SW is really unpredictable ...

And I must say, the set not only looks good, but even better than the previous two sets with the upright standing shoes.

Here is the top side of the set, right next to it, the three connected shoes from the previous 20 FUD set.



And here the bottom side with a view of the treads, which feel a bit rougher, but which is explainable, since they were touched by the support wax, but which is not a problem. But the top and side surfaces are smoother because they were not in contact with the wax.



And if one looks carefully, one can even see the small holes ( 0,2 mm), although not on all shoes, but one could even drill out them, if it should be, although they later are hardly visible anyway.  



Here's a little closer view.





And so I will seize the moment and order a further seven sets, wherewith I would then come on the required 456 Track shoes, but I will still order additionally a further Set of 20 to be on the safe side.

Hello everybody,

the Set of 20 is already on the way, and of the remaining seven Sets of 52 six are already printed, only the last one is missing, which is why the shipment will follow soon.
And thus the Crawler would be almost finished already ...

P.S.: Your Shapeways shipment is on its way!

Hello friends,

although I have already experienced some things, Shapeways still has some surprises in store.
Today came the already announced Set of 20 Flat Ori (FXD). But after I unpacked it, I could not believe my eyes.

Because that was not the Track Shoe-Set I ordered,


Source: shapeways.com (Crackerjazz)
but any other one with little mini parts,





what of course I've immediately complained.

Mitchell Jetten (SW) but immediately apologized in return:

Oh no, I'm sorry to hear we shipped the wrong model to you.
I have raised a complaint (CT-48214) ticket right away and asked our production team to reprint the correct model as soon as possible.

There are also less beautiful wonders by SW ...

Hello everybody,

today, Shapeways' big Track Shoe delivery arrived with the seven Sets of 52, which of course were immediately unpacked.



And these are the total of 456 shoes for the Crawler. The new sets look well, though there are small differences in quality between the sets, as one can see on the two encircled sets, which should be due to different thorough after-treatment/cleaning.



But that is no problem, because I will try anyway, to let the sets being cleaned professionally again in the Dental laboratory, as usual.



And the replacement delivery with the Set of 20 (FXD), which had been interconverted, is already on the way. 

For the connecting bolts, I've also still found a suitable solution, for which I would use instead of the insect needles ( 0,3 mm) now Nickel silver rods ( 0,4 mm), which  fit closely through the Pin lug holes.



And with a length of 7 mm per bolt comes together a total length of more than 3 m , which would correspond to 11 rods 30 cm, which I will reorder.

Hello everybody,

today came the complained Set of 20-Flat Ori (FXD),


Source: shapeways.com (Crackerjazz)

which looks impeccable, and one can even see at all shoes the small holes in the treads.





Only the sticker on the bag makes me perplex, which displays the upright set,



Unlike the last Sets of 52-Flat Ori (FUD), which all had rough treads, the treads of this set are nicely smooth, as if they were not lying on the support wax, weird ...
But I don't care at all.

Hello everybody,

after the slowly tiring Track shoe story today again a little puzzle for relaxation.
What do you think, what this could be?



At least it's not a slice of crispbread.
Well, is it dawning?

Hopefully its related to modeling and a section of the crawler way

Hi Mike,

not bad, but unfortunately not quite right.

But I do not want to keep you on tenterhooks for long.

And therefore here's the short solving on the back.



Hard to believe, but it's actually a piece of the original Spray-on foam insulation (SOFI) from the ET-138 which was flown at the last mission of Atlantis (STS-135)

But how I came to this rarity, I would have to tell you separately in an own thread, if you are interested. This is a great story connected to another contemporary witness from the glorious shuttle era who has also written an amazing book, so to speak a "must read" for any space aficionado.

Thanks Ron, and Hello everybody,

after my contact to the two SOFI experts Craig Capdepon and Vincent Morales was unfortunately interrupted, I got a hint from a friend of the ARC Forum that I could also contact Scott "Shuttleman" Phillips

He was an Engineer at the Marshall Space Flight Center in Huntsville, Alabama, and was working on all ETs during the Shuttle program. And the man with this telling nickname has written this great book together with his wife Dianne Phillips, which tells the story of his personal thirty-year shuttle odyssey. 


Source: Scott G. Phillips

And this book with this striking red Remove Before Flight Ribbon, that gave him the title at the same time has cast a spell over me after reading a about it and seeing this  Book Trailer of his son Christian Phillips.

During his time working in the program, he was also able to join his two passions - the Space shuttle and woodworking - by building one-of-a-kind handcrafted wooden tribute shuttle models in large numbers for many Shuttle crews and also for friends, here among others when handing over to the STS-1 crew with John W. Young and Bob Crippen, which also were signed by them. 


Source: Scott G. Phillips

Realizing that each mission carried historic weight, Scott Phillips set forth to preserve each flight through his work as Master Carver, true to his motto: Long live the Shuttle's legacy.
And in the meantime, I have contacted him and also ordered his book, which arrived yesterday along with a few surprises.



It was next to his book with a personal dedication,



as well as the red ribbon and some stickers,



and as icing on the cake this piece of SOFI foam, which he had branched off in the production of the last External Tank ET-138, what I have asked him for, which I am especially proud of now.



More about this, i.a. also to the explanation of this ribbon as a hanger for the book, then in my thread about the "Shuttleman" Scott Phillips, who can also be found on Facebook.
So much for now.

Hello everybody,

meanwhile, my friend Joe (crackerjazz) from the ARC Forum found time and has started with the 3D modeling of the Main Sprockets, of which I need 16 pieces, which Shapeways should print in FUD.



Initially, he had only used the front view of the drawing I had supplied and apparently had some problems with the implementation in his CAD program (Solidworks), especially with the dimension 33,6''.



But then I pointed him to the side view, which shows that this value is the measure at the lowest point of the lower curve of the wheel, what he probably had not considered.   



And now he seems to cope with it, as his following pictures show.











As it looks the modeling seems to be pretty tricky, but he'll get it done, I'm pretty sure, so keep fingers crossed!  
I can only watch again and be amazed ...

Thanks my friends for your continued interest.

Hello everyone,
well, this drive wheel really seems to be a hard nut, if one has a look at the next pictures of my friend Joe, who has diligently continued to model.


Source: arcforums.com (crackerjazz)



At least here it becomes clear how many sub-steps are obviously necessary to capture and model all these contours and ledges,





until finally this single sprocket is finished, which looks great.



But I think, that now not much is missing to make a suitable 3D printing set out of it. And that's why I've thought about the most favorable arrangement/orientation for printing and think that the sprockets could be arranged flat in a set consisting of two rows of nine wheels, whereby I would have two spare wheels.
Now I'm curious to see what will come out in the end and what such a Set of 18 in FUD will cost.

Hello everybody,

My friend Joe just asked me if it would not be better to just print only one sprocket first, to see if will mesh well with the Track shoes, which would certainly make sense. 

Therefore, I had already pointed out to him in advance that the following condition had to be guaranteed, namely, that W2 fits into W1


Source: microartwork.com (Mischa Klement)

But that would have to be guaranteed, provided that the drawings are correct, whereof I go out, and provided that he has correctly implemented them in his model (1:160).

Therefore, he should first upload only a single, flat-lying wheel, so I can let print it in FUD and FXD on a trial basis. After the aptitude test we can then decide about the final Set of 18.
Well, just wait and see!

Yeah,

I was going to ask about that my friend.

Fitment needs to be established between the track shoes when linked together and the sprocket before you go into production just in case some adjustment needs to be made. (probably to the track shoe pin distance) The proper pitch of the track needs to be maintained....

Otherwise the track when assembled won't fit around the sprocket....

Therefore let's wait until the first two Sprockets are printed, then follows the nail test with some linked track shoes around the sprocket, then we're smarter ...
