Thanks for the comments guys. I got my brass from the hobby shop and found some square stock I used for the axle. It was a little labor intensive to make. I was going to make 2 more but decided after the first one that if I do, I will try to use the existing plastic leaf spring assembly and only make the axle, spindles and steering bar out of brass. If I could make them more efficiently I'd sell you one, unfortunately I don't think I'm ready to start another one yet, too many other projects on the back burner.
