Back from holidays ! Well…more exactly after the sequence: Comic Con Paris, a week of summer camp (cooking with some 13-15 years old children), during a week the organisation for the next camp, two weeks in a camp of life-size role-play (13-17 years). And me / us again!
I didn’t have much time to think about the project during these two month, so I continue where I stoped, and I carry on and talk about the rest.
So, coming back from the Comic Con, we brought back the long awaited (three months late) Backpanel! Which is now in my garage, ready to make himself up for molding. In the meantime, I’ll give you some interesting information that can be gained from observation of the piece, hoping that it will be useful for some and interesting for others.
In a general way, the Backpanel is an arc of 70cm thick. It is the ninth of the circle formed by the Stargate™. It is a part which is at the rear, and at each end is added a chevron.
Here are some steps that give an idea of the size of the piece:
Thanks to them, we can determine the exact diameter of the outside door which is 593cm (not 22 feet as it seems to be said in a making of) and the inside 461cm.
The piece has a total weight of 8.9 kg, a full serving should so weigh 25 kg with the electronics (but without the metal frame).
In therms of visual, the entire part look like this:
At each end there are geometric shapes with straight superimposed edges on two levels, these are usually under the chevron, we see one part that shows itself under.
I invite you to check the image bank to see it : https://picasaweb.google.com/106154105695443794525/Relief Note that the forms at the back are not the same as the front ones.
The first sculpted row of the Backpanel is made of 25 repetitive forms as well as two halves at the ends:
What follows is the second part as you can see in the first picture, however it is useful to focus on the different lines of engraved decorations on top, as well as the rest of Backpanel:
Below these symbols we find many small rectangles, 74 in number.
Then some rows of reversed V which are intersected with upside down triangles this way:
/\_ v v_/\/\/\/\/\/\_v_/\/\/\_v_/\/\_v_/\/
We see here the ends:
The edges are completely flat:
The piece is not completely flat, we can be interested in several thicknesses:
That’s about everything, except these two little interesting details: first the small rectangles of the last frieze have been placed by hand, as we can see, they aren’t quite straight. Secondly, here is one of the circle that is at the outer end of the gate:
A not very well known thing, there are several hooks in the back, they are here 8 in number, probably used to fix the iris, there is also a guide / central ring which I do not know the utility:
Some will be surprised, but overall, the paint is a big black layer that became a bit bluish gray. A brushed paint gray / silver has been rubbed above it to give the metallic effect. This technique is widely used for this type of apperance, for exemple to give the impression that a plastic gun is metal.
During a multiple draw of the same mold, we see that some flaws appear, like here on the first image. Besides this detail, we can see a repentance on the gate, the artist removed a part or didn’t complete it. If we can deduct it, that’s because on the master (third image) we distinguish that this piece does not exist either. Finally, between the grooves, there are many tiny beads painted later, I wonder what it is, difficult to remove them without damaging the molding piece, they are therefore likely to remain on the final prints, what a pity, but it is not grave.
So here is the piece that will serve as a basis for all the cover of the SG. As a bonus, a few large cracks :
The Backpanel here is not so heavy because it is made of very thin layers of resin and chopped fiberglass. We see a first layer of black gelcoat too.
Well, all these photos in order to inform you that it’s a serious project, that we will return to work like a beaver and that we have good basics. I’ll keep you posted for further work!
