Then a gust of wind hit. The Stargate held together, the base didn't tip over, but the metal braces attaching it to the base gave up and folded and it ended up face down anyway.
Much swearing ensued.
Then I did some field re-engineering and put it up as a seven-chevron partial gate so it would fit flush against the wall under the overhanging 3rd floor balcony.(This is as much of the gates as you usually see in most episodes of the series anyway, as there is a ramp/pedestal obscuring the lower two chevrons). We had to do front projection of the event horizon effect, but it was still very effective.
It was also wildly popular.
Once it was dark, I went out and took some pictures with my phone.
