I took down my old tree fort today. This fort was my first large engineering/design project. It was built out of scrap lumber, salvaged nails, and small trees. A lot of the wood had rotted and I didn't think it was still structurally sound. But it turned out to be sturdier than I expected. I guess I over built it a bit.
|The front first level is about 24 years old.|
|The back half and second floor were built between 24 and 15 years ago.|
This was a long term project. With a lot of design changes.
|I expected the who thing to come down when we pulled on the main tree.|
Instead the tree snapped in two places and the fort just held it up.
|After I pulled the two front supports on the same side as the tree.|
|I pulled out one of the back supports. The chain slipped off the other one...|
Surely if we pull out the other support it will topple over.
|Nope. Still standing with no supports at all on the north side.|
Safety factor >> 2 :)
|It finally fell over after we cut the middle tree and three of the four trees on the south side.|
