I think it's crazy what you and your son can accomplish, really shows how 1 person can make a difference. The project has gone far! Not something that can be easily done i think. It looks like a good environment you're working in, wondering if you're close to done.
This is something that any son and father would love to work on together, I assume.
Far from done, but coming along nice. I probably would have a VERY VERY hard time alone on such a project. But with the help, and smart idea's coming from My wife @leemlaframboise and two awesome kids, I'm finding ANYTHING can get done.
