i took a power pole and built a spinning teeter totter for my kids, i used a 3/4" hard steel rod for a center pivot rod, but it broke due to the teetering and the tottering, obviously the spinning was not a stress on it. I would like a larger diameter rod and one that wouldn't snap, so it needs to be springy---- what should i look for. I would reuse or salvage something if i had an idea where to look, or i would buy a new chunk of steel if i was sure what to get. i need something with plenty of spring, maybe an inch in diameter and 24" long. what would i buy?
