RG Aile Strike Build Day 12

Shoulder back together

Introduction

Welcome to “RG Aile Strike Build Day 12” where I am building up an RG Aile strike model. If you haven’t read any of the other parts I would recommend going back to the start. You can find that here. In the first post I covered the box, runners and provide the manual.

I am taking my time to ensure I clean up all the marks that can be cleaned up. As with any build like this, if you end up with discolouration or a small white “stress” mark you are likely to need painting to get rid of those. I may have a look at simple quick methods of dealing with those items, especially as I find that it has a habit of happening on the grey pieces. I also accept I may need to work on my cutting style as I’m sure that will contribute to it!

The Break

Ok, normally at this point I outline the process that I follow for taking the parts from the runners and cleaning them up. However I have a confession. You may, or may not, have noticed that recent pictures the model was nor sporting their right shoulder pad. This was, I had to admit, not the models fault. Rather I had been a little too keen with the nippers and rendered the joint that clips over the arm to hold the shoulder in place weak.

The part looks like this:

Broken part
Broken part

I guess it would probably be more accurate to say the piece shouldn’t look like that. It should be more a horseshoe shape and less of a “on no some spoon broke me” shape.

What to do?

There there were a few potential options. The first would be to just glue it in place, but that would render the arm with very limited mobility. The next option would be to cut a small square of plasticard to size and then file away till I have something that works. The final, and far more fun option would be to design a piece in some 3d software and print one out.

Which did I choose?

I’m guessing from the way I loaded the what the options were, we all know I went down the 3d route. I recently bought a small 3d printer with the specific view of printing adapters for the stands I sell in the shop (here). They are cheap and versatile but I wanted to offer people the opportunity to get some slightly different connectors.

So that means I have a small 3d printer to-hand (*whew*).

My final model looks like this:

Simple 3d model of shoulder joint

During the process I printed and tested multiple pieces tweaking the width of the legs etc.

Pile of shame

Finally I reached one I was happy with and slotted everything back together. It isn’t perfect, and I may need to tweak it further but I can print more if needed!

As you can see it appears to be doing the job. On the whole an evening well spent I feel. I also got to use the 3d printer which is a bonus!

Conclusion

I was the one who broke the part. I must have trimmed it too close when using the nippers. However, this goes to show that with a little time and patience there are options to work around broken pieces.

HG Gunpla Arms

Labelled Arm Parts

Introduction

In this post I want to highlight the lovely technicalities that Bandai have built into the models. This post specifically I want to focus on looking at the HG GunPla arms … or more specifically my RX-78-2 Revive arm.

Before I go any further I must, I feel, apologise for the state of the arm. I have been doing a lot of testing different things with it. It has been painted, cleaned painted and generally messed with. It looks currently in a slightly sorry state. I will, soon I hope, restore it to a much better condition. When I get chance I will show it off in its restored glory!

The Arm Basics

So this model, and a few others I have built, follow a similar pattern for the arms. This model has a lower section which would serve as the ulna and radius. Then a top section that would be the humerus. The ulna and radius part has two parts clip over it, with the humerus having a piece slide down over it.

In the images above the parts have been colour coded. Firstly the red highlighted part is the humerus. Next is the blue highlighted part which acts as the ulna and radius. Finally is the green highlighted part which is the plate which holds them together. You can see in the next picture the top plate of that is in place holding the main “bones” of the arm together. In the first image the parts labelled 1 shows where the top and bottom part hook over the posts allowing them to pivot.

The following images show the arm being built up, and the level of movement it has once put together.

What do I like?

This design is both robust and flexible. Once put together it allows for a great range of movement bending the arm and thus allowing me to put the model into far more poses. The pieces can break (I did it on the other arm) but that was user headspace error, rather than the parts. There is a load of detail on the parts, but a lot of those details are also functional. It looks like there are grooves and sections, but a lot of them, as well as looking nice, aid in guiding, and holding, the pieces in the right places. The final thing I wanted to mention is the high quality / precision of the pieces. They fit together snugly, helping to hold everything where it should be, and provide a level of stability that looser pieces just couldn’t. All of these small details add up to make the arm a fantastic piece. Both from an engineered point of view, but also from a pure aesthetic point of view.

Conclusion

I am a massive fan of the thought and design that has gone into the HG Gunpla arms. Ultimately the models really shine because of the attention to detail.
