Talk about differences: why the Stargate™ of the series ?

“Is there any reason you chose to recreate the Stargate™ of the series rather than the movie’s ?”

That’s a very good question, asked by some on Twitter. So I will answer here and take this opportunity to talk about the differences we find between each model of Stargate™.

The (well thougt out) excuse:

It’s technical.
As regards the movie’s Stargate™, each chevron is engaged, except the main chevron which is juste there to choose the symbol to enter. That’s why a pneumatic system was chosen by the technicians who worked on the first SG. We notice also that the chevrons’ moving is more violent in the movie.
Moving parts of the chevron: front crysal, back crystal (which rises), front V (which goes down).
The chevrons in the movie certainly don’t light, there is so indeed less to do about, but on the other hand it’s more difficult to create a complex mechanical system than a simple electrical system. In our case, only the V and front crystal must move. Besides, the symbols are engraved in the first opus, and from the very beginning of the SG-1 series, they are raised, that means, more simple to make.

The true reason:

It’s of course sentimental.
THE Stargate™ for me has always been the one that’s in the first series. I grew up with and so it makes sense to me to start with it. Also you, if you’re here, it’s because you spent at least 10 years with this model. It’s a part of your daily life (week and/or weekend). Remember !

So, what are these small differences that we don’t see at first glance ? Here a list which should be exhaustive:

Comparison table:


If you have found other differences between the doors, don’t hesitate to tell us ! We could have missed something.

Some sources (if ever you don’t believe what I say): 


Here the famous bar which is only seen on the movie’s gate. She’s put between the wings of the front and back chevrons.



The back of the gate doesn’t switch on, it’s post-production in SGU and only for this series. We also see the sheet which replaces the bars we saw earlier (this detail exists only on the main chevron in SG1).


The two crystals rise.




A new version of the inter-chevrons bars. What a talent ! This is the same which is on the internal opposite side of the gate.






SGU’s gate is activated via a touch-screen system with stylus. A smartphone ?




Summary Tables : Projects Progress

The following tables give a concrete idea of ​​the project’s evolution.

Of course, you’re welcome to bring us your help, we need it !
It’s possible to give us advices, make suggestions and give your opinion on what has been made so far.

If you’re not good in technical fields, we are looking for source images, for the collar for example, but especially for the glyphs at the moment.




Complete description

The main form of the Stargate™ is a ring, we can however notice, that it becomes narrower from outside to inside at the level of the thickness. Every type of piece is being  reproduced several times identicaly. The gate is made with resin and fibreglass, erected on steel.

The detached parts :

are 9 in number and divided at the level of the chevrons:

– The interior ring:

Its finishing touches are not optimal, the joints meet up not in a continuous way between the engravings.

The front Ring has as well a perpendicular part, who concludes the Stargate™ inward, this one is made of 19 triplets like these:

-The exterior ring :

The engravings are the same everywhere.

-The back panel :

It gathers the front pieces of the Gate in one piece.

-The frieze/the flange :

It stands between every chevron, is composed of a multitude of geometric form arranged on two levels.

Are larger:

-The moving ring :

It’s composed of 39 glyphes divided among 8 plaques (7×5 and 1×4). The joints are between the glyphes at the level of the bars.

-The chevrons :

Either they are in front or behind, they are composed of five parts: a main V (in moving sometimes ) and a interior V as well as a transparent orange part and two “pads” right and left too.

The main Chevron has a grey plaque on its transparent moving part. The interior V of the front chevrons is retied to the part that we see behind, and who has many geometric forms. This plaque is the one who reties it to the gate, contrary to the back chevrons, who have not this plaque, because it is molded with the back panel.

We count so 10 type of different pieces and 39 glyphes, 129 pieces in all. Excluding the mechanisms and the steel basis.

The mechanisms :

-The lights :

It concerns bulbs with lengthened filaments. They stand under the transparent orange part of the Chevrons.

They come on slowly . With the exception of the main chevron, who comes on and turns off every time a chevron is locked, the other chevrons light and stay until the Stargate™ closes.

-L’anneau mobile :

This one begins to turn clockwise, then anticlockwise, slows down just before the desired glyphe be in front of the main chevron. It’s with a motor having some little cogwheels that we make turn the ring , who’s placed on a big cogwheel at its exterior end. At its interior end we find a steel tube who is placed on little wheels. Note this: the noise of rumble of the gate is generated by little steel strips who beat at a bar.

-The main chevron :

Once the desired glyph under it, the V drops down almost to the inner ring and lights along with the orange part, which is itself raised about 5 centimeters (but only the front part).

Here the rear lights, however, because the model does not include originally some light at the back we can think that this is done by editing with a computer . Maybe it is only the main chevron that has this light. Difficult to be certain with the shooting of the series.

Then these two moving parts return to their places and switch off, the ring goes in the other way.

The complete procedure :

-We first enter the symbols  either in the SGC program (I have a version made by fans) either on a DHD.

-With the DHD :

Each time you press a symbol, it turns on, as well as the one on the door. Note this: they light up in the direction of clockwise starting with the chevron located to the right of the main one. Once all symbols are entered (usually 7), the door opens, then the chevrons remain lit until its extinction. Strangely, if you compose seven symbols, the two chevrons at the bottom of the door (sometimes buried) do not light.

-With the programme :

Once the symbols entered in the computer, the door rotates in clockwise until the symbol be in front of the main chevron, it is as mentioned above, and at the same time the first chevron lights (and the rest), then the door starts again to do the same anticlockwise , once the 7th, 8th and 9th chevron are locked, the door opens. I have no idea which chevron does not light if one composes eight symbols, it is usually either the 4th or 5th. The chevrons remain lit until the extinction of the door.

The main door is molded plastic, the mechanism inside is metal, each piece is attached with screws placed at a specific location for the chevrons and a little random at times on the door itself. In the first episode of SGU we can see the screws, and even loops screwed behind which are probably used to hang the iris.

The iris :

Talk about it! This is a big round one piece that fits exactly in the middle of the door, the bottom is engraved in a piece, the front bouquet is made of 20 parts. They are cut from sheets of plastic and then painted.

The DHD :

It is composed of a base, of 39 symbols and a main round.

But of a cache at the front too, behind which there is a blue apparatus and transparent plates.
In one episode, the keyboard of DHD is removed, we see below largely transparent panels illuminated as before. (It is almost impossible that the usual keyboard and this panel will be found together in the DHD, this is probably an adaptation for this episode.)

Happy new year

In this last morning of 2011 I think about my good resolutions, and I think too that this year, I have only informed you about the progress of MY project. But originally, this blog should be useful for bringing informations about the Stargate, in order to help people who would like to recreate a part of it.
But I didn’t give the tools to those, who maybe would like to embark themself on a project like mine, without having the necessary budget to buy already existing pieces of the Stargate.
Here is so the measurements of the V Chevron. You must know that I will pass every possible measurements as soon as I’ll receive or/and carry out them.
Thanks to Stephen for his precious help.

I wish you the best for this new year, and I set one’s heart on finishing this year what we began ! ^^


Some of you are maybe interested by the pictures which I’m referring to work with (I was speaking of it here : The Stargate from a new angle).

So here is a Picas album with almost all the pictures I found (except of course the ones I can’t reveal).

If I find some new pictures, I will update the album.

I hope these pictures will be useful, don’t hesitate to send me some like that, that’s useful, especially in HD.

Under the chevron

The beach !  Not really… (Joke based on the french proverb : “Sous les pavés la plage.”)

Here are the geometrical figures we can find under the Chevrons on the back of the gate. It’s not perfect but useful as a reference. When it will be time to build the gate we’ll use exact sizes and photographies.

Thanks to Zat that brought me the detailed pictures of this piece.


Inner ring : Lines

You certainly noticed that, on the central ring of the Stargate™, there are some lines, just like on most weapons and others goa’uld extravagances.

So I looked for these lines in order to draw them accurately. You have to know that there’s a line set for the outworld gate, and an other one for the SGC gate.
The SGC set of lines changed many times because of repairs during the different seasons.

So I was interested exclusively in the last versions of the line set. We find notably images in the “Stargate™ Artifact” catalog of Propworx, but it’s the single image that I had, I did my best with it.

If however you have in your possession this catalog and some time to use, you could check my drawing, and tell me if it’s correct.
There is the picture:

Maybe you will be surprised to see some lines who don’t follow each other….well it’s normal, that’s not an assembly default (as I thought first) but really a will of the artists who realized the gate.

I hope you still continue to follow the progress of the project with interest, don’t hesitate to write any comments here, you help me to speed up, whichever things you critizise.
