I made these from an old cylinder of wood I had laying around. I used a hand saw to cut the chain. I fit the chains into the sticks by cutting a notch for them with the bandsaw, then I sanded the sticks with #220 grit sand paper. Once the chains were in place, I drilled a hole through the chain link that was stuck into both sides, and I bolted them together. Finally, I finished my nunchaku by staining them with Dark Cherry colored stain.
