I once started to make a wind generating propeller from a clear piece of 2”x 6” clear yellow cedar. I found plans with offsets in a Mother Earth book and got underway in my shop one Saturday morning. When I went home for lunch I had one half just about perfect. I went back at it after lunch and it was a good hour before I noticed that I had two leading edges on the same side ……. 🙄😝
It spent several weeks on my burn pile grinning at me but I had the last laugh …. And a great bonfire party as I remember. 🤣😂

The early bird gets the worm but its the second mouse that gets the cheese.
