Thanks Elliott.

Secret life....I wish. It sounds so much more exciting to have a secret life as a rocket scientist than say the usual "spy" (not that I am a spy either!).

Hi Kevin

fantastic job...........
I will try to build it in 1: 100, with LUT and crawler from Educraftdiversions

Dear all

So now it is time to do the last part of the 1/24 thrust structure, namely the internal support struts of the F-1 engine fairings

I found that accurate scoring and folding was essential for these (as well as the fins done previously). When creasing it was best to get a really sharp crease and when doing the ends (particularly where a crease runs right to the end of a point, like on the tip of a fin) I found it best to use tweezers (with "flat" ends) to get the crease to go right where it should.

Here are all the parts cut out (note that the last of the four parts 30 on pages 8 and 9 is not printed correctly) and then them folded

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12184.jpg

I was very conscious that I am going to have to keep moving this model about from room to room (so that we can live in the house) whilst it is being made. It just fits through the door and I know I am going to catch the fairings (sooner rather than later knowing me). So I wanted to make the struts in such a way that if a big bash happened then then struts would give way at a glue joint rather than bending and crushing a strut. My thinking being re-gluing a joint is much easier than printing and remaking a new strut. Although the struts are easily able to make all the spans required on the 1/24 model by themselves, I decided to to put strong internal "cores" inside them so that they would give way at the glue points if a big bash happens. Since this is not in the instructions I will (as usual) detail exactly what I did.

For all but the longest struts I used the stem of a cotton bud. I used "Johnsons" (shown below) since they have paper stems (most cotton buds have plastic stems). It is easy to strip off the cotton wool buds from each end and then cut to the required length (which you want to be accurate)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12222.jpg

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12223.jpg

The stems were the perfect diameter (if not you could always increase the diameter by gluing the correct thickness of paper around the stem). A stem was glued to one of the inside faces of the strut and then the strut was glued. In the second photo below it is supposed to be of a strut "end on" so you can see the "core"

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12225.jpg

For the four longest struts (part 29 of pages 8 and 9) the cotton bud stems were too short. I did not think that "joining two of these stems together was a good idea since it would most likely "hinge" at the joint under any pressure thus not do what it was being put in there to do. Instead I used bamboo kebab skewers (which were of the correct diameter) cut to the correct length. (Not paper nor wood but hey it is a grass!). Here are the struts with all their cores inside them as well as all the "tabs" for the fairings glued together.

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12226.jpg

Next I glued the tabs onto the fairings (as per instructions)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12287.jpg

And then sealed all the ends of the struts and joined together the struts (again as per the instructions)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12288.jpg

Then glue the struts to the fairings as per the instructions. Here is the first fairing done.

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12289.jpg

As you can see everything matches up exactly on this fairing. This is not the case on all the fairings. What is crucial is the actual curved shape the inner and outer fairing has taken up. There is one and only one curve for which all the struts will then hit all their contact points exactly. As this scale a tiny variation in fairing curve means a little bit out for some strut. Fortunately for me, two of the fairings were spot on and the other two were such that the struts were at most 1.5mm out for any strut. If it had been more then you could have, in a worst case scenario, struts being too short. So I was lucky.

Here are some photos of all the fairings finished

So the finished 1/24 thrust structure can now be assembled!

Dear Helmut

Thank you for your kind comment.

I look forward to seeing your "full set" of Saturn V, LUT and Crawler.

I recently purchased the Educaftdiversions 1/144 LUT model.

Educaftdiversions do several different scale sizes. If you have not already purchased your copy you may find it worthwhile reading the first 10 or so posts of the thread by mk310149 (in particular post 10 by NYC Irishman)

LUT from Edu-Craft

Dear all

I have finished the 1/24 thrust structure.

So I thought that I would take a few photos. First of all upside down (which is the easiest)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12296.jpg

Then Gunter and Wernher have a look

(ignoring "health and safety" rules!)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12299.jpg

I then had to build a special "stand" in order to put the rocket on its side.

Four more

Did you notice Gunter and/or Wernher in any of the four photos above?

A few more photos in the next post...

Hi Kevin,
thank you for the Info. I got the 1:96 version yesterday for my 65th birthday

.
i know the thread from mk310149. Michael´s postings (in german forum) are the reason why I want to build rockets

**Algebraist** · #**250** 03-18-2018, 09:31 AM

Dear all

So carrying on from my previous post here are some more photos of the 1/24 completed thrust structure.

First the "space voyagers" 1/144 Saturn V

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12309.jpg

Now along with the 1/48 model

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12310.jpg

Now added the 1/24 model

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12312.jpg

Finally I wanted to do some with the rockets standing vertically. The 1/24 model is getting noticeable in its weight. I think the F-1 engines could take the weight but I was not certain, so being cautious I removed the centre engine and put a stand in its place.

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12314.jpg

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12316.jpg

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12317.jpg

It is getting really hard to get everything in shot. However to try and get the feel of the size I took three last photos (by lying on the floor!)

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12318.jpg

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12319.jpg

1/24 Apollo/Saturn V (enlarged 1/48 Greelt et al version)-sdc12320.jpg

You have all been by patient waiting for progress, I went over the top a bit with the photos. It does feel like a bit of a milestone though. I hope you have enjoyed them.

So now it is onwards and (most certainly) upwards.

Regards

Kevin
