Abstract
A method of making a stabilizer bar from a tubular blank to which a mixture of an adhesive and powdered metal is applied to the inside surface of opposite ends of the tube. The adhesive is cured and then the fuseweld powder is placed in an oven to melt the fuseweld powder. The ends are swagged to shape flat tubes ends that are trimmed and pierced to form a fastener eyelet in each end. The stabilizer bar is then heated for hot working to form the bends along the length of the bar. After forming to shape, the stabilizer bar is quenched and annealed.
