Keeping myself humble, sharing my mistakes. I tried to make a leaf spring front a while back. I used bicycle forks, and a leaf spring from a old Ford. It seemed pretty solid and rode very nicely. One day, I was moving from the street to the sidewalk, and the there was a gap on the side of the sidewalk. The front tire dropped into that gap. I'm not real sure what happened after that. I went over the handle bars and tumbled down the sidewalk. But I was ok, yea! Then the bike landed on me. I carried the damn thing home with a broken hand and some good cuts and bruises. Near as I can tell, the front wheel bent just enough to jam it in the forks, then tumbling. I ordered a springer type front end, and a new wheel, and had the bike back on the road in a few weeks. Don't be like me kids. Overbuild everything.
