A hammer bank assembly for use in line printers. The assembly includes an extruded metal rear frame having a uniform thickness and a plurality of machined mounting surfaces which are machined in accurate relationship with respect to one another. A pair of extruded plastic shoes are mounted to the top and bottom of the frame and also include machined surfaces for accurately aligning them with respect to the frame. The shoes include a plurality of mounting slots which are cut by means of a gang cutter. The slots serve to accurately align a plurality of print hammers in the shoes. The hammers are insulated with respect to the frame and the shoes in order to prevent sliding motion and subsequent wearing of the print hammers. Also disclosed are several methods of simplifying the construction procedure of the hammer bank assembly.
