I have no training, but I love backyard engineering. I’ve posted before about the pond I built.
But my pride and joy is the zipline I built over my pool. Some have a slide or diving board, but I think I have the only pool zipline.
The posts are steel vineyard anchors bolted back to back.
One end is sunk in concrete in the dirt with rebar for stability, and a guy wire attached to a Japanese maple.
The other end is buried in the concrete of the pool deck and it is bowing because there is nowhere to anchor any counter tension. But it ain’t going anywhere.
Tension on the cable is from a boat cable winch rated at 1600 lbs. The bolts that hold it are rated at 1000 lbs, and the cable is stainless steel aircraft cable. I don’t think it’s going to break.
The carriage was purchased on line from a backyard zipline company. Disclaimer: this is not the intended use of their product. The manual showed it run on a slack cable between two trees or something. I threw that horseshit right in the garbage and got to work on my pool.
It has a stop in the line so it stops over the deepest part of the pool. It is cobbled together from parts I had around with a Nerf basketball to cushion the stop.
It is a popular attraction for kids and grown ups. What do you think of my design? I am open to comments and criticism, especially from those who actually know something about this sort of thing.
As a bonus to Zoidberg, this is similar to my first car when I was 16. There are some pictures of the real deal (and frighteningly 16-18 year old me) in storage that I will share eventually. Have to find them. This will do for now.
