I tried it but the spokes are too small in diameter and would only work in soft ground. I tried to use them for stakes for my titanium foil wind screen but had the same results. Also I don't think they're the right alloy and they bend fairly easily. They do make great bail handles and I have modified several of my pots.
I found a source at a local shop that focuses on racing bikes and has a box of used spokes that I can paw through for the least bent up. They charged me a dollar a spoke.
