I'm a little proud of this: My first attempt at a mukyanyong! The arms are concentric PVC pipes with a threaded rod running through, and I drilled some extra holes for tent stakes around the base. The arms are too short and too low, and there's just a little more flex in the post than I want. The next one will have better caps on the arms. I'll also wrap the middle with my white belt and the lower part with dock line for shin kicks. I'll make a bill of materials once I get it straight.
