Hey guys I work in a tech shop for semi trucks and large tractors. On the back of a semi there are square steel bars that are used to hang mudflaps. I'm told they are spring steel. So I've gathered several that were replaced and were going to be scrapped. After cuttin both ends off your left with about 25 inches of half inch square. So I thought I would try my hand at forgin some tongs. Things aren't working out. The first two attempts they broke right at the neck and boss area. So after looking at a couple tongs that I bought I narrowed it down to me making the neck too thin. Something else I noticed is how hard they are. Has anyone tried making tongs out of spring steel? I mean tryin to draw out the reins is really tough. I'm just wondering if these are in fact spring steel. I thought it would be a good experiment and good practice since it was free steel and about the right length and size. Most videos I've watched about making tongs they use either square or round stock about the same size I'm trying these at but they don't say what type of steel they're using. So I'm wondering if practice is all I'm goin to get from my mystery steel or will they make a decent set of tongs. Any advice would be great.
