I love Osage Orange, it is an ugly duckling that blooms into a swan. What I love about the wood is the strength, the resistance to decay and the natural curves, as well as the color. There are Osage Orange (called “hedge” locally) fence posts in this area that are over 50 years old, still standing strong. When exposed to sun, the beautiful yellow-orange turns gray…but just the upper millimeter or so. I used the Jamestown varnish diluted with naphtha. Multiple coats. I’m curious to see how effective the UV protection of the Jamestown varnish will be. The bench is about 7 feet long and weighs over 300 lbs. The bench seat board is about 3 inches thick.
