Well alternating riveted and welded would of course be better, but alternating riveted and butted is the closest approximation that I can actually make. For the riveted rings I have found the easiest thing to do is to flatten the entrire ring usign a flattening jig, a 3/4 inch thick piece of steel with a 1/2 inch hole for a 1/2 inch grade 8 bolt used as a piston. A few whacks with a hammer does the job. <p></p><i></i>
