Abstract
A method of fabricating a chain tensioner includes bending a sheet metal blank to form a connector portion perpendicular to a flat base. The connector portion has an arm extending beyond the base. The method further includes stamping an end of the arm to curl the end into a hollow cylinder having an axis perpendicular the flat base. Curling the end into a hollow cylinder may be performed in a series of stamping operations. The blank may define a gap which extends around a narrower portion of the arm after the end is curled into the hollow cylinder.
