Here it is!


The owner installed the chain to hang the net swing temporarily, then asked me to move the swing. An outdoor aerial silk is supposed to reside here one day.


Check out the plans. The basic concept is there, but the homeowner wanted the addition of a climbing net, a zipline, a beam for the aerial silk, and a good place to mount the net swing. For cost reasons that eliminated the slide and monkey bars. The fold down table became a doorway for the climbing net. The climbing wall got lowered from 9′ to 8′ and 7′ wide to 8′ wide. The zipline resulted in changing from 4 x 4 posts to 6 x 6 posts and adding all of those diagonals.

The zipline, due to height of the playhouse and surrounding topography is steeper than suggested. So we began to look for a way to slow the ending. I added a spring and a friend added a magnetic break. They work on the same principle as dropping a magnet down a copper pipe. Copper does not magnetize but it does conduct electric current well. Therefore, when the magnet is moving down the pipe a current is induced which has a magnet field which just happens to be counter to the magnet’s field. The magnet is slowed by this counter-EMF. So is the magnet surrounding the zipline cable. The black bungee brings the magnet back to the point for the next braking action. So, the zipline is fast but has a controlled stop.

It’s a pity when life gets in the way of blogging (just kidding!). But I have so many thoughts and experiences from the summer that I could blog for quite some time. It is not likely to happen as I see more things happening soon, but that’s OK.
I did want to share a few thoughts and pictures. I don’t often suggest books for several reasons. I do more technical reading than reading for pleasure, and frankly many books don’t meet my high standard of what I would unreservedly pass on to those I call friends, or enemies for that matter since I want them to one day be friends. A book that I can enthusiastically suggest is “The Book That Made Your World, How the Bible Created the soul of Western Civilization” by Vishal Mangalwadi. Because of his culture and his faith he simultaneously looks at the West as an outsider and insider at the same time. I keep having the feeling that he is correcting much error from lies our culture has fed us about how we got to where we are. He uses personal experiences and copious quotes to show the deep imprint of the Bible on western culture. I think that you will hear more about it here once I am finished with it.
My friend, colleague, and climbing partner, CC, took me to two boulders I’d never been to before. In fact, he had only been there a few days before with another climbing buddy for the first time cleaning about ten problems, laying a thick base of branches in a wet spot, and clearing part of a large fallen tree. I was privileged to try out the new rock. I like to go back to old familiar routes, but there is a particular excitement about trying new routes, and particularly ones that haven’t been climbed before. I was definitely not climbing at the top of my game, only topping out on a V1 and 3 V2’s. I tried two V4 and got shut down. Both problems involved a gaston with my left hand that I could not stick. It has challenged me to train that weakness. On the second one I discovered that if I did a side pull with my right hand instead, I could top out to the left much easier. We both agreed that it would rate as a V2. I decided to name it “Easy Out”. The two pictures are of me on the right sidepull and the topout. We saw several Cardinal Flowers in the wet, rich spots by the creek. I definitely want to go back, and hopefully clean some problems on new rock myself. (Photo credit: CC with his phone)
