Drive wheel spokes

The spokes added to the drive wheel. Two problems: I should have used a smaller size stock for the rivets, and the stock used was unusually brittle. I've peened a LOT of rivets since I started smithing, and I've never had them crack like these. However, they do hold the two pieces together well. I may replace the rivets, or forge weld the spokes to the wheel and grind the rivet heads off. I haven't decided yet. Even if I leave it as is, it's perfectly functional, it's just more of an aesthetic thing.
