Hi, I have a Ryobi 725r weed wacker that I'm using. The only problem is that the clutch drum assembly is a really weak aluminum. I can't weld anything to it. So i need to somehow make one with a lathe(which i don't have), or find one with a spindle already on it. If you guys have any tips or suggestions. I'm making my bike and trying not to spend money on it. So far all the parts have been free and i intend to keep it that way. The most i would spend is about $20. If you guys have a place where i can get a clutch drum assembly made from steel, well that would really help. If you have somewhere where i can get it already with a spindle, well that would be the best thing ever.
