%X The rectification of eccentricity was revealed to be more effective in tube sinking than drawing wan a mandral. The ratio of thickness to diameter of tube blank on both sides of thick and thin wall seems to be the principal influen- tial factor in rectifying eccentricity. The greater the initial outside diameter and the initial wall thickness difference are and the less the initial wall thickness of the tube blank is, the better the rectification.
