Development of extrusion as a means of making Hanford cored slugs is continued in this report. Eccentricities of the thick-wall tubes required have been a major problem in meeting an arbitrary specification of 0.032-inches. This eccentricity is defined as the difference between centers of the inside and outside diameters. A new method of insuring better concentricity is described which involves a special type of dummy block. A series of heat-treated uranium dingots were also extruded as rod and found to require lower pressures than normal vacuum cast uranium.
