A novel method of forming a finishing chamber by inserting a cylindrical tube into a corresponding opening in the bottom of a dished tank head having a bottom and an upwardly-extending outer wall, inserting a cone-shaped gusset or collar having an outwardly and downwardly-extending skirt and an opening in the top thereof, corresponding to the circumference of the cylindrical tube, over the tube and with its outer circumference in contact with the tank head, and welding the tube to the tank head and to the gusset and the gusset to the bottom of the tank head, thereby simply to provide the essentials of a finishing chamber, is disclosed. The outer wall of the finishing chamber may be extended by welding a sheetform annular ring to the top of the outer wall of the tank head, and the chamber may be lined with elastomer and fitted with a screen deck. The chamber itself and finishing machines embodying the same are also disclosed, and are characterized by simplicity of fabrication and structural stability of the chamber, and numerous advantages in operation which follow therefrom.
