I made my own "peening press" out of some old craftsman 1/2 inch drive extentions. The radii on the extentions at the ends matched almost exactly the radii needed on the center sleeve after peening. I just put the extensions into the center sleeve, clamp in a vice and squeeze until the center sleeve is peened properly.
