This reminds me of a story: We had a cabin once, which needed a window sill replaced. When we removed the window sill, we discovered there was rot in the wall, so we had to remove the wall. With the wall removed, it seemed foolish to not take the opportunity to add a small bathroom. (We had been using an outhouse, which, with two small kids, was never a "convenience.")
In the local Lynn Lake garbage dump, where many good items were "stored," we found a fancy, "clean-waste" toilet, which heated up so deposited materials could be removed from the bottom in powder form. This we installed—without first using it to see how it worked. It heated up so much that it was actually dangerous. Later, we were told that the previous owner, while indisposed, had managed to burn some valuable "private parts." Thus, the discovery, of what we called "The Wonderbiff," in the dump. Armed with this vital information, we were determined to make the contraption work. With the Wonderbiff installed, we were now an indoor toilet family. Everyone used the biff, and as the contents heated and were turned to powder (actually a disgusting kind of crust which had to be chipped off a sort of hot plate inside), we noticed an odour we had not perceived before. Our neighbour, who was familiar with lakeside living, advised us to install a "stink-stack" on the roof of the cabin, to disperse any disagreeable smell.
We returned to the dump where we found pipe and flashing. The dump was our "Home Depot"; a place where you could find everything from good furniture to fine used clothing. We called it the "exchange." On the roof of the cabin, we discovered more rot, loose shingles, and a large squirrel’s nest. A portion of the roof had to be replaced. We thought that real soffits might make a difference, and these we ordered from a catalogue. With the wall and window replaced, the roof repaired, the bathroom added and the Wonderbiff installed, we had spent an entire summer, and a huge amount of cash, all because a window sill needed replacing. This, I’m sure, is a saga cottagers and homeowners everywhere can relate to: the ripple effect of a simple repair. *Sigh*
