I have a need for a piece of tubing which tapers from 1 1/4 inch OD to 1 inch OD over 16 inches in length. Material would be DOM seamless steel tube, wall thickness would be 0.090. I need six pieces. Normally this would be made by rotary swaging, but generally swaging dies are only 12 inches long so it would take two sets of dies at roughly $2,500 per set. Too pricey for six pieces, probably they wouldn't touch such a small quantity anyway. I thought about using heavy wall tubing and turning the taper on the ID and OD but gosh, a 3/4 inch boring bar at 16 inches would chatter so bad I don't think it would work. Any good ideas?
