Rough Cut of "Perfect Circle"

Well, I finally got up the courage to do a rough cut of the "perfect circle," the circle on the inner dome that shows through to the outside world. I hadn't been this anxious since I drilled the holes in the inner frame for the gas pipe connecting the arms. If I had botched this, it would have pretty much ruined my dome, so a lot was riding on it.

It turned out okay, certainly good enough that I can now start using a bottle neck with sand paper to sand it down to a round circle. Cutting out all the other circles in the dome first was good practice for this one. I'm glad that's behind me, I can breath a bit easier.
