1st) I made this devise to twist rope strands between 2 16gage wires. 2 1/4" eye bolts 1 @ 1.5" long and 1 @ 5" long drill a hole in the wood. Bolt on the short eye bolt so it will not move. The longer eye bolt must be bolted on so it can freely turn. Make a handle with scrap wood and put a 6" bolt in the opposite end. This will be the crank handle.
