Know anyone in Indiana? Osage Orange is almost a weed there. Know anyone in Texas? Ask them for Bodark. That is what is called here. Because of the shape of the trees, it is full of stress wood and so very few folks will mill it into lumber because it warps and twists so badly unless you can find a large and straight tree. Most trees are bent and twisted resulting in a lot of stress wood.
If you have worked with it, you probably already know that you can make a very bright yellow dye from the sawdust. I discovered it by accident when I was making a chair from Osage Orange . I had been working all day in the shop cutting, sawing and sanding and had Osage Orange dust all over me at the end of the day. As I was coming into the house, my wife told me to strip off my clothes as I came into the utility room and put them into the washing machine so I wouldn't drag wood dust into the house. I did as she asked and went on to take my shower. While I was in the shower, I heard her yell something to me and came to see what the problem was. The Osage Orange dust on my work clothes had stained everything in the wash yellow. Fortunately, she was able to get it out but I was forbidden from using Osage Orange to make anything ever again. It was okay because I didn't like working with it anyway.
